1.2 RAID terminology

Redundant Array of Independent Disk (RAID) is a storage technology used to

combine multiple inexpensive drives into a logical drive to obtain performance, capacity

and reliability over single-disk storage.

RAID 0 - Disk Striping

In RAID 0, data is divided into pieces and written to all disks in parallel. This

process is called striping because the pieces of data form a stripe across multiple disks.

This improves access rate, but makes availability lower, since a single disk failure will

cause the failure of the array. A RAID 0 array is unsuitable for data that can not easily be

reproduced, or for mission-critical system operation.

Figure 1- RAID 0(Disk striping)

1-3

RAID 1- Disk Mirroring

In RAID 1, data is duplicated on two or more disks to provide high access rate and

very high data availability. This process is called mirroring. If a disk fails, the RAID

controller directs all requests to the surviving members.

Figure 2- RAID 1(Disk mirroring)

RAID 3- Disk Striping with dedicated parity

In RAID 3, data is divided into pieces and a single parity is calculated. The pieces

and parity are written to separate disks in parallel. The parity is written to a single

dedicated disk. This process is called striping with dedicated parity. The parity disk

stores redundant information about the data on other disks. If a single disk fails, then the

data can be regenerated from other data and parity disks.

Figure 3- RAID 3(Disk striping with dedicated parity)

1-4

RAID 5- Disk Striping with distributed parity

In RAID 5, data is divided into pieces and a single parity is calculated. The pieces

and parity are written to separate disk in parallel. The parity is written to a different disk

in each stripe. Parity provides redundant information about the data on other disks. If a

single disk fails, then the data can be regenerated from other data and parity disks.

Figure 4- RAID 5(Disk striping with distributed parity)

1-5

RAID 6- Disk Striping with two sets of distributed parities

In RAID 6, data is divided into pieces and two sets of parities are calculated. The

pieces and parities are written to separate disks in parallel. The two parities are written

to different disks in each stripe. Parity provides redundant information about the data on

the RAID member disks. If two disks fail at the same time, the data can still be

regenerated from other data and parity disks.

The RAID 6 algorithm uses two independent equations to compute two sets of

parity, which enable reconstruction of data when two disks and/or blocks fail at the same

time. It greatly improves the data availability.

Figure 5- RAID 6 (Disk striping with two sets of parity- P and Q)

1-6

RAID TP(Triple Parity) - Disk Striping with triple distributed parity

In RAID TP, data is divided into pieces and three sets of parities are calculated.

The data pieces and the parities are written to separate disks in parallel. The three

parities are written to different disks in each stripe. Parity provides redundant

information about the data on the RAID member disks. If three disks fail at the same

time, the data can still be regenerated from other data and parity disks.

The RAID TP algorithms use three independent equations to compute triple parity,

which enable reconstruction of data when three disks and/or blocks fail at the same time.

It greatly improves the data availability.

Figure 6- RAID TP (Disk striping with triple parity – P, Q and R)

JBOD – Just a Bunch of Disks

JBOD stands for just a bunch of disks. In JBOD mode, the host will see each drive

as an independent logical disk. There is no fault-tolerance in JBOD.

Figure 7- JBOD (Just a Bunch Of Disks)

1-7

NRAID – Non-RAID

In NRAID mode, all drives are configured as a single logical drive without

fault-tolerance. The total capacity of NRAID will be the sum of each drives.

Figure 8- NRAID (Non-RAID)

RAID 0+1 – Disk striping with mirroring

RAID 0+1 is a combination of RAID 0 and RAID 1 to form an array.

RAID 30 – Striping of RAID 3

RAID 30 is a combination of RAID 0 and RAID 3 to form an array. It provides better

data redundancy compared with RAID 3.

RAID 50 – Striping of RAID 5

RAID 50 is a combination of RAID 0 and RAID 5 to form an array. It provides better

data redundancy compared with RAID 5.

1-8

Summary of RAID Levels

The following table provides a brief overview of RAID levels. A high data availability

number indicates high fault tolerance.

RAID Level Description Capacity Data Availability Minimum

RAID 0 Disk striping N 0 1

RAID 1 Disk mirroring N/N 5 2

RAID 3 Striping with dedicated N-1 1 3

RAID 5 Striping with distributed N-1 1 3

RAID 6 Striping with 2 sets of N-2 3 4

RAID TP Striping with triple parity N-3 4 4

RAID 0+1 Disk striping with N/2 2 4

RAID 30 Striping of RAID 3 N-2 2 6

RAID 50 Striping of RAID 5 N-2 2 6

NRAID Non-RAID N 0 1

JBOD Just a bunch of disks N 0 1

This chapter introduces a simple way to configure the RAID system. It is written for

those who use Maxtronic RAID system for the first time and want to create an array

quickly. It includes these topics:

� Section 2.1, “ System diagnostic during boot cycle ”

� Section 2.2, “ LCD screen symbols (drive status)”

� Section 2.3, “ Menu navigation and mute system beeper from front

panel ”

� Section 2.4, “ Quick Setup - Flow chart and procedures ”

2.1 System diagnostic during boot cycle

Figure 9 displays a flow chart of the RAID system self-test on boot-up. During boot-up, the RAID system executes CPU, peripheral device, host and, disk chipset initialization. It consists of three modes (A, B, and C).

A - Initial RAID status

The RAID system has not been configured. Drives have not been installed;

there is no RAID configuration present in the hard drives and RAID controllers

NVRAM.

B - RAID system initializing

The RAID system is configured and drive initialization has begun.

2-2

C - RAID system exists

The RAID system has been configured. There is a RAID configuration present

in hard drives and RAID controllers NVRAM.

Figure 9 - System Diagnostic Flow

Note:

The RAID configuration is stored both in a reserved area of the hard drives

and RAID controller’s NVRAM after an array set is created.

2-3

2.2 LCD screen symbols (drive status)

The LCD screen shows an overview of RAID system drives status. This

section explains the meaning of symbols that appear on the LCD screen.

Symbol Meaning

R The drive has an error or a fault

I RAID system is identifying the drive

S Global hot-spare drive

X No drive installed or drive is offline

W Warning – Too many bad sectors or unrecoverable data blocks in the drive or drive triggered “SMART failure warning” after running Disk SMART test

A The drive is being added to an array either during online expansion or rebuilding

C A clone drive (target drive)

1~8 Array group number that a drive belongs to

J The drive is in JBOD mode ( No configuration mode)

Below are some examples.

Example Description LCD Screen

2.3 Menu navigation and mute system beeper from front

panel

The RAID system can be configured using the front panel function keys.

Menu Navigation from LCD Panel

Key Description

“UP” arrow key. To select options or scroll forward each character during data entry

“Down” arrow key. To select options or scroll back each character during data entry

ESC To escape or go back to previous menu screen

Enter To go to a submenu or to execute a selected option

Mute System beeper from LCD panel

The RAID system emits a beeping sound periodically when an error or

failure occurs in the disk array. This audible alert can be turned off temporarily

for the current event by pressing “UP” and “Down” key twice simultaneously.

The beeper will activate again if a new event occurs.

2-5

2.4 Quick Setup – Flow chart and procedures

This section provides a quick way to configure the RAID system with one-click

using the front panel. The RAID system will automatically create a single array

and map it to its first host channel.

Before you begin

It’s not recommended to connect the RAID system to the host computer before

completing configuration and initialization. If connected during configuration

process, resetting the controller could lead to occasional host server error

messages like parity error or synchronous error.

Note:

To ensure power redundancy, connect the power supplies to a

separate circuit, i.e. one to a commercial circuit and one to a UPS

(Uninterruptible Power Supply)

Using the unit without a UPS will greatly increase the chances of

data and RAID configuration corruption.

2-6

Quick Setup Flow

Figure 10 shows the quick setup from the front panel function keys.

Figure 10- Quick Setup Flow

2-7

Quick Setup Procedures

Step1. Insert drives into RAID system Make sure all of the drives are mounted

securely to the disk trays and insert disk trays

into disk slots.

Step2. Power ON RAID system

Note: After powering on. The LCD status

should display as seen to the right.

Ex: Model Name: SA-6640S

Step3. Enter password “0000” to login Main Menu from LCD

Press “Enter” key.

“Enter Passwd” message will appear on the

LCD screen.

Use “ ”or“ ” to select each character and

select “0000”, press “Enter” to proceed

Note: “0000” is the default password.

Step4. Select RAID level in Quick Setup

Go to “Quick Setup->RAID Level”

Use “ ”or “ ” key to select the desired level.

For example: 6+spare, Select “Yes” and

press ”Enter” to proceed.

Note: If a spare drive is not selected or reserved,

all of the installed disks will be configured as a

drive member of Array 1.

RAID level options in quick setup:

0/1/3/3+spare/5/5+spare/6/6+spare/TP/TP+spare

/0+1/30/50/NRAID

TP: Triple Parity allows three drives to fail in a

single array

Step5. Automatic system initialization

After setup, the system will begin to initialize.

It may take several hours depending on the

total capacity of the array.

Step6. Connecting host computer to 1st host channel of RAID system

Power off RAID system and connect 1st host

channel of RAID system to host computer.

Power on RAID, wait for the unit to completely

power on, then power on host computer.

2-8

Note: Before connecting RAID system(SCSI) to host server(step 6) 1. Check the SCSI/FC ID of RAID system and the HBA to ensure that

they are not sharing the same ID with another device on the same

channel. The default SCSI ID of RAID system is 0, Fibre ID setting

is Auto.

2. In a SCSI daisy chain, SCSI termination is required on the last SCSI

device. Make sure it is properly terminated on SCSI bus.

3. Before you disconnect or connect a SCSI cable from the RAID

system, power off the host computer, than the RAID system for

safety. Also note, SCSI bus does not support hot-plug function.

Step5. Assign IP address of RAID systemObtain IP address automatically

The default ethernet setting of RAID system is DHCP enabled. Connect

the RJ-45 port of RAID system to a dynamic (DHCP) network. An IP

address will be automatically assigned to the RAID system.

Use “Up” and “Down” arrow key to navigate the LCD screen to get the IP

address of the RAID system.

Assign IP address manually

The RAID system can also be assigned with a static IP address via LCD

manually.

1. Enter password “0000” from LCD panel to login in RAID utility

2. Use arrow key to go to “System Params->Ethernet Setup->DHCP”,

select “Disable”

3. Return to “Ethernet Setup” to set the network manually.

Use “Up” and “Down” arrow key to assign,

IP address: xxx.xxx.xxx.xxx

Main Menu

The following figure is the main menu for SCSI/FC RAID system after logging into

the monitor utility using a VT-100 terminal program.

3.1.2 Setting real time clock(RTC) and checking drive health

In order to perform advanced RAID functions, such as scheduled disk scrubbing,

SMART disk cloning and recording the date and time of event messages, etc the

real-time clock must be setup.

Refer to Chapter 4 for detailed information about disk scrubbing, SMART.

Real Time Clock menu tree

Step1. Go to “Main Menu->System Params->RTC”

Step2. Select “Set RTC” to set the clock for RAID system in the format of

“MM/DD/YY W HH:MM”

Symbol Range Description

MM 00~59 Minute

Checking drive health

Go to “Main Menu->Utility->Disk Utility->Disk Self Test” and run “Short Self

Test“ for all disks.

If the suspected disk fails to pass Short Self Test, it’s recommended to

replace a new drive or run Extended Self Test to further investigate drive

health. For more information about Disk Self Test, see Chapter 4, Section

4.3.

The RAID system can be configured up to 8 array groups with different RAID level and

each array group can be divided into a maximum of 16 slices.

Follow the following steps to create and slice an array.

Step1: Choose the stripe size of RAID system

Go to “Main Menu->Array Params->Stripe Size” and select a stripe size

based on what kind of application behavior will be applied.

Recommendation:

1. Using the default stripe size, 128 sectors (64 KB), should be sufficient

for most applications.

2. Choose 256 sectors (128KB) stripe size if host application is mainly

sequential read/write IO

3. Choose 32 sectors (16KB) stripe size if host application is mainly

random read/write IO

Note:

Once the stripe size is selected, it will apply to the whole RAID system. All

arrays will use this specified stripe size.

3-12

Step2: Decide whether or not to create an over-2TB slice (Optional). Skip this

step if you do not wish to create a slice over 2 TB.

Currently, there are two ways to break 2 TB limitation per slice.

One is to change the sector size or enable 16 byte CDB(Command

Descriptor Block)

2.1 Go to “Main Menu->Array Params->Slice Over 2 TB” and select

“enable”

2.2 Select “Sector size” or “16 byte CDB”

Note:

1. Currently, “Sector size” option is supported for Microsoft Window

2000/2003/2003 SP1 “16 Byte CDB” option is supported for Window

2003 server SP1

2. If Slice Over 2 TB option is disabled, after initializing an array if the

capacity is over 2 TB, the RAID system will automatically create multiple

slices limited at 2TB.

Step3: Create multiple arrays groups

3.1 Go to “Main Menu->Array Params“, then select an array number

3.2 Go to “RAID Level”, and select a RAID level

3.3 Select drive members of the current array.

Note: Hot-spare disk is not a member of an array, reserving at least one

spare drive in a unit is recommended.

3.4 Press<Escape> until the main menu appears

3.5 Repeat the step 3.1~3.4 to create more array groups.

Step4: Creating slices of an individual array

4.1 Go to “Main Menu->Array Params“, then select the array you want to

divide into slices.

4.2 Go to “Slice”, and select the first slice - Slice 00, type the size in

megabyte(MB), then press <Enter>.

Note: The output area will display the slice size that has been created.

4.3 Repeat Step 4.2 to create the next Slice 01 until the array is divided as

planned

Note: It is not allowed to create slices randomly. Create slices in

ascending sequence, for example: Slice 00->Slice 01…->Slice 15

3-13

Step5: Setting initialization mode

Initialization mode has two options, foreground and background. With

foreground initialization, an array will be accessible after initialization is

completed. With background initialization, an array will be accessible

during initialization.

5.1 Go to “Main Menu->Array Params”, and select the array group

5.2 Go to “Initialization Mode”, and select a mode you prefer, for example:

background, the array can be accessed during initialization.

Note: It may take several hours to complete foreground initialization

depending on the total capacity of an array.It’s recommended to set

“foreground” mode to double check drive health during RAID system

initialization.

3.1.4 Assign SCSI/FC Channel ID & Mapping LUN to hosts

Every device requires a unique SCSI or Fibre channel ID. A SCSI chain can

support up to 15 SCSI devices with “Wide” function enabled. A Fibre loop can

support up to 125 FC devices. If there are multiple host computers that require

access to the same storage device (LUN) than there must be clustering or

multipath I/O software installed on these computers.

Note:

Maxtronic RAID also supports host-based multipath I/O software

PathGuard.

3-14

SCSI/Fibre Params menu tree

Assigning SCSI or Fibre Channel ID

Setting SCSI ID

1. Go to “Main Menu->SCSI Params”, then select a SCSI channel for

example: SCSI CH1

2. Select “Set SCSI ID”, then select a SCSI ID

3. Repeat Step 1~2 to set another SCSI Channel ID

Setting Fibre ID

1. Go to “Main Menu->Fibre Params”, then select a Fibre channel for

example: FC CH1

2. Select “Set Loop ID”, then select “Auto” or key in a number (0~125)

manually.

3. Repeat Step 1~2 to set another Fibre Channel ID

3-15

Note:

1. Check the SCSI/FC ID of RAID system and the HBA to ensure that

they are not sharing the same ID on the same channel.

The default SCSI ID of RAID system is 0, Fibre ID setting is Auto.

2. In a SCSI daisy chain, SCSI termination is required at the last SCSI

device. Make sure it is properly terminated on the SCSI bus.

3. QAS(Quick Arbitration Select) setting is required for Ultra 320

devices. If the QAS setting on the RAID system differs from the

HBA, there will be problems accessing the RAID unit from the host.

Refer to the following table to properly set QAS option in SCSI

Mapping LUN(s) to a host channel.

LUN mapping is the process to make a slice visible to a desired host channels.

Each LUN will appear as a storage device to the host computer.

1. Go to “Main Menu”, then select “SCSI Params” for SCSI RAID or “Fibre

Params” for Fibre RAID

2. Select a specific host channel, for example: SCSI CH1 or Fibre CH1

3. Go to “Lun Map”, and select a LUN number.

4. Select an array, then select the desired slice to map to the chosen LUN

Ex. SCSI Params -> SCSI CH1 -> LUN Map -> LUN 0 -> Array 1 -> Slice0

This will map Slice 0 of Array 1 to LUN 0 of SCSI Channel 1

Note:

i. The same slice may be mapped to multiple LUNs on separate host

channels, but is only applicable for clustering or multipath environments.

ii. Selecting “Disable” will delete a LUN map. Deleting a LUN map will not

delete the data contained in the array or slice.

5. Press the <Escape> key to return to the Main menu

6. Repeat step 1~5 for each slice until all slices are mapped to a LUN

an array with different drive members, RAID level, or stripe size, delete the existing

array and then reconfigure the array.

To delete an array, follow these steps:

Step1. Go to “Main Menu->Array Params”, and select the array you want to

delete

Step2. Go to “RAID Level”, and select “None”

Step3. Select “Yes” to proceed

Step4. Go to “Main Menu->Save Config” and select “Save to NVRAM”. The

RAID system will not automatically reboot, and the array will be

deleted immediately.

Caution:

Deleting an array will destroy all data contained in that array.

3-18

3.3 Deleting a slice of an array Follow these steps to delete a slice

Step1. Go to “Main Menu->Array Params”, and select the desired array

Step2. Go to “Slice”, and select the last slice in the array, for example: Slice 02

Step3. Type “ 0 ” (MB) to delete Slice 02\

Step4. Return to “Slice” then select “Slice 01”, type “ 0 ” (MB) to delete Slice 01

Step5. Go to “Main Menu->Save Config”, then select “Save to NVRAM” to take

effect the change. Delete slices in a descending sequence.

Similarly, you can follow the same steps to change the slice size.

Note: The use of a third party storage resource management (SRM)

software or an OS file management program to divide or stripe a slice

may lead to data fragmentation that causes decreased I/O performance

of the RAID system.

Caution:

Deleting a slice will lose all data contained in that slice. Backup

your data before deleting or changing the slice size

3-19

3.4 Expanding an Array Follow these steps to expand an array.

Step1. Go to “Main Menu->Array Params->Expand Array”, and select the

desired array

Step2. The disk numbers will then prompt, select a number that will add to the

array

RAID system then enters on-line expanding process automatically

After array expansion is complete, a new slice will be created from the

added capacity.

Refer to Section 3.1.4 to map the new slice to the desired host

channel/LUN.

Note:

Expanding an array will impact system performance, performing

array expansion during off-peak time is recommended.

3.5 Regenerating an arrays parity and performing a parity

check

RAID parity might become inconsistent with data after extended periods of time.

Users can re-generate array parity or perform a parity check to ensure data integrity.

Follow the following steps to expand an array.

Step1. Go to “Main Menu->System Params“ then select “Init Parity” to

regenerate RAID parity or “Parity Check” to verify the parity

consistency.

Step2. Select the desired array, then select “Start” to proceed

Note: After the RAID system starts parity check if a parity inconsistency is

detected, the parity check will stop and report a discrepancy.

Refer to Chapter 4, section 4.1 about disk scrubbing to correct parity

errors.

Note:

Init Parity and Parity Check can only be performed when RAID

system is in an optimal condition.

3.6 Configuring SAN masking for FC disk array

SAN masking is a RAID system-centric enforced method of masking multiple

LUNs behind a Fibre channel port. As Figure 13 shows, with SAN masking, a single

large RAID device can be subdivided to serve or block a number of different hosts that

are attached to the RAID through the SAN fabric. The host servers that access a

certain LUN through a particular port can be masked from accessing other LUNs

through the same port.

SAN masking can be setup on the RAID system or the host computers HBA.

Masking a LUN at the device level is more secure than masking at the host computer,

but not all RAID systems have LUN masking capability; therefore, some HBA vendors

allow persistent binding at the driver-level to mask LUNs.

4.1 Disk Scrubbing – Bad block detection and parity

correction

Objective

With the increasing capacity size of hard drives, storage subsystem vendors

face the challenge of handling bad blocks and parity errors. Bad sectors can form on

HDD areas that are not accessed for long periods of time. These problems may lead

to unrecoverable data loss. In order to effectively solve the problem and improve

data availability disk scrubbing (DS) was developed. DS can scan for bad sectors

and/or parity errors in a RAID array. The RAID system reconstructs bad sectors

from other sectors and re-assigns it to an undamaged area. At the same time it also

detects parity inconsistency; users can decide whether or not to overwrite

inconsistent parity. DS is a proactive approach to address data integrity, it maintains

the RAID system in a good condition.

Unrecoverable data loss

As Figure 14 shows, although all of disks, disk #1~4, are online at t=t0, block

number D3 is already a bad sector. Even after the rebuild process is completed at

t=t3. Data block D1 will not be able to successfully regenerate from the other data

and parity blocks.

Figure 14- Unrecoverable data

4-3

Parity inconsistency

Over long periods of time, parity blocks may not be consistent with data blocks.

This may result from unexpected power outages or resetting the RAID system

before cached data is written to drives. If the parity inconsistency is detected, it

indicates a data error exists either on the data disk or parity disk. However, the RAID

system can not determine if the error resides on data or parity disks because of the

RAID algorithm. Enabling “Overwrite Parity” in disk scrubbing will automatically

correct data on the parity disk whenever parity inconsistency is detected.

If the array’s parity is seriously damaged, with overwrite parity enabled, data

loss may occur after disk scrubbing is completed. Disable it if the parity data has

been seriously damaged.

Figure 15 describes the detailed flow of disk scrubbing (DS). When DS is

running, the controller will read data and parity blocks of a stripe in an array and

execute a parity check. DS predicts data block failure and corrects parity errors in

order to enhance data integrity and availability.

Figure 15 function description of disk scrubbing

4-4

Note:

1. Disk scrubbing can only be activated when the array is in

optimal condition. This means there are no drive member

failures in the array and no background task in progress, i.e.

array expansion etc.

2. Disk Scrubbing will impact I/O performance; running DS during

off peak times is recommended.

3. If the RAID system is powered off while DS is running, it will not

resume on the next power up.

Follow the following steps to configure disk scrubbing.

4.2 Auto Shutdown – RAID system in critical condition

Objective

The RAID system will be protected against internal overheating condition or

UPS AC power loss. In the RAID system, there are several thermal sensors located

on the RAID controller and midplane. If the temperature increased to a dangerous

level in the RAID system, it may damage internal components including disk drives.

With auto shutdown enabled, if overheating occurred or AC power loss is detected,

the RAID system will shutdown after a given time duration.

Under the following conditions, auto shutdown will activate automatically if it is

enabled.

1. System temperature exceeds threshold

2. All fans failure or not available

3. UPS AC Power Loss

Auto shutdown menu tree

Note: System real time clock (RTC) must be activated in order for the auto shutdown

feature function properly.

Follow the steps to set up auto shutdown,

Step1: Go to “Main Menu->Utility->System Utility->Auto Shutdown->Enable“

Step2: Select “Event Trigger” and enable or disable each trigger option.

Step3: Select “Shutdown duration”, for example: 15 min, RAID system will turn off

the power automatically after 15 minutes if shutdown event has triggered.

Note:

1. If the event triggers are disabled or critical events return to the

normal, auto shutdown will be inactivated or canceled.

2. If an auto shutdown event is triggered, the write cache will

change from “Auto” to “Write-through” mode to ensure data

integrity.

4.3 Disk Self Test – Check drive healthy in RAID system

Objective

Disk Self Test (DST) is used to test the health of disks with them installed in the

RAID system. Prior to DST a user would have to remove disks individually and run

a vendor proprietary disk utility in a separate host computer DST predicts the

likelihood of near-term HDD degradation or fault condition.

DST performs write test, servo analysis and read scan test on the disks.

Follow the following steps to check disk health condition in RAID system,

Disk Self Test:

Step1: Go to “Main Menu->Utility->Disk Utility->Disk Self Test“

Step2: Select “Short Self Test” and select “All Disks” or “Disk X” to start

drive self test

Step3: Select “Extended Self Test”, if there is any error occurrence after

short DST (Step2)

Then select “All Disks” or “Disk X” to further check the suspected drive.

Swap the suspected drive if it doesn’t pass Extended Self test.

Note:

1. Running DST before creating an array is recommended.

DST will not overwrite data.

2. DST can only be executed in offline mode. This means that if

there is any host activity DST will be terminated and host I/O

access will resume.

3. DST can also be performed thru LCD function key directly. Key

in password- “1111” to start short or extended self test of all

drives.

4. It may take several hours to run Extended DST depending on the

drive capacity and spindle speed.

5. Most newer hard drives support DST, contact your drive vendor

to see whether your drives support DST.

4-10

4.4 Disk Clone – Manually cloning a failing drive

Objective

Hard drives are the most likely component to fail in a RAID system, and are

very difficult to predict when the failure will occur. When a failure does occur the

RAID unit will have to regenerate data from the non-failed hard drives to rebuild a

new drive, and during this time the RAID system will be in degraded mode. This is

where Disk Cloning (DC) can aid a user. Disk Clone can copy a failing drive to a hot

spare, and upon completion of cloning, the new cloned disk can take the position of

the failing disk immediately or can stand-by until the cloned disk fails. Disk cloning is

to help prevent a rebuild from ever occurring and having the unit in degraded mode.

There are two options to clone a failing drive: “permanent clone” and “swap

after clone”.

In "permanent clone" mode, the clone disk (hot spare disk) will be the mirror of

the source disk until the source disk has failed. The clone disk will then replace the

source disk.

In "swap after clone" mode, immediately after the clone process is complete the

clone disk replaces the source disk and the source disk is taken offline.

Disk Clone menu tree

4-11

Follow the steps to start disk cloning manually,

Step1: Go to “Main Menu->Utility->Disk Utility->Disk Clone“, then select “Start

Disk Clone”

Step2: Select “Source Disk” which is the suspected failing drive in the array.

Step3: Select “Target Disk” and select a target drive. (Clone drive)

Note: Only the hot-spare drive will be displayed in target disk.

Step4: Select “Start Permanent Clone” or “Start Swap After Clone” to start disk

clone.

After DC is complete, the target disk (clone) status will be marked with a “C”

on the LCD panel.

Step5: Repeat these steps to clone other drives.

Note:

1. If cloning is in progress, and the source disk fails or goes offline,

the cloning disk will replace the source disk and become array’s

member drive. Also the RAID system will begin rebuilding at the

point where cloning stopped.

2. If cloning is in progress, and a member drive fails in an array,

excluding the source disk, the cloning will stop and the RAID

system will begin rebuilding.

3. Disk clone can only be performed while the array in an optimal

condition.

4-12

4.5 SMART – Predicting a drive failure and automatic disk

cloning

Objective

Disk Clone (DC) is a process of manually cloning data from a source disk to

target disk. With the SMART function, the RAID system monitors drive health on

preset polling intervals, if hard drive degradation is detected or the user-defined bad

sector threshold is reached, the cloning function will begin immediately.

SMART Event Trigger

There are two SMART event triggers that will begin disk cloning: a SMART

failure flag, and a user-defined bad sector threshold. The SMART failure flag is

triggered by the drive, and is defined by vendor-specific attributes that may differ

model to model. The user-defined bad sector threshold is a specific number of bad

sectors per drive. The user must input the bad sector threshold to start disk cloning.

SMART Mode

There are four modes in SMART function.

1. Disable:

SMART function is inactivated.

2. Enable ( Alert Only) :

The RAID system monitors using drives SMART on preset time intervals. When

a SMART failure is detected, the user will be alerted with a beeper and the

drive’s status will be changed to a “W” on the front LCD which indicates a

warning

3. Enable ( Permanent Clone) :

The RAID system monitors drives SMART, if a SMART failure is detected or

user-defined bad sector threshold is reached, disk clone will begin. Upon

completion, the clone disk (hot spare disk) will be the mirror of the source disk

until the source disk has failed.

4. Enable ( Swap After Clone) :

The RAID system monitors drives SMART, if a SMART failure is detected or

user-defined bad sector threshold is reached, disk clone will begin. Immediately

after cloning has completed, the clone disk (hot spare disk) replaces the source

disk and the source disk is taken offline.

4-13

Follow the following steps to configure SMART function,

4-14

SMART menu tree

Follow the steps to configure SMART function,

Step1: Go to “Main Menu->Utility->Disk Utility->SMART“, and select “Test Disk

SMART”

First, check whether or not your drives support SMART. If your drives don’t

pass SMART test, drive’s status will change to “W” on the LCD screen.

Step2: Go to “Bad Sector” and decide the value of “Threshold for Clone” or

“Threshold for Swap”

For example: Threshold for Clone: 130, if a drive accumulates 130 bad

sectors, disk clone will start. Threshold for Swap: 200, if a drive

accumulates 200 bad sectors, the source disk will be taken offline.

Step3: Go to “Disk Check Time” then select a time interval to monitor drive’s

SMART and bad sector status. For example: 60 minutes

Step4: Go to “SMART Mode”, then select the mode you prefers.

Note:

1. Make sure system clock is enabled before configuring SMART

function.

2. If bad sector threshold is disabled for Clone and Swap, disk clone

will only be activated when drives a SMART failure is detected.

4-15

4.6 AV Streaming - Performance-critical streaming

application

Objective

Bad blocks and read or write delays of drives are unavoidable in a RAID system.

For AV streaming applications, such as broadcast, post production, video/audio

editing application, etc., these errors will cause choppy audio and/or video frame

loss. In some instances the entire RAID system will stop operation.

Enabling AV Streaming option in the RAID system can eliminate the chance of

data transfer delays in a performance-critical streaming application. AV stream

option will shorten drive I/O response time, re-arrange cache buffer management for

read/write commands and changes the algorithm to read/write data.

Only enable the AV Streaming option after it has been tested in a real AV

streaming environment by an experienced engineer.

AV Streaming menu tree

Follow the steps to configure AV Application,

Step1: Go to “Main Menu->Utility->System Utility->AV Streaming“, then select

“Enable”

Step2: Go to “Disk Timeout” and then select a disk I/O timeout value, for example:

3 seconds

Note: Once AV streaming option has been enabled and disk timeout has

been changed to a low value, the RAID system will frequently alert

remapped blocks in the status log.

Step3: Go to “Remap Threshold” and then select a threshold that the RAID

system will start to alert remap warning message.

4-16

Note:

1. AV streaming can only be enabled for a single array configuration.

If multiple arrays are present in the RAID system, AV streaming will not

work.

2. Single array and single slice is the optimal RAID configuration for AV

streaming. Partitioning an array into multiple slices for AV streaming is

not recommended.

4-17

4.7 Disk Standby Timer – Hard Disk Spin Down

Objective

Disk Standby Timer command makes hard disk to go into idle state when no I/O requests are

directed to the hard disks within a selected period of time. Allowing the disks to spin only when

needed greatly reduces power consumption and thereby decreases operational cost and may

extend the MTBF of a hard drive.

Follow the steps to configure Disk Standby Timer,

Step1: Go to “Main Menu->Utility -> Disk Utility -> Disk Standby Timer “.

Step2: Option items: Disable (default), 5 mins, 10 mins, 15 mins, 30 mins, 60

mins, 90 mins and 120 mins. Select proper period time.

Note:

Restriction: firmware will reject "Disk Standby Timer” operations under

below conditions.

a. AV Streaming function be enabled.

b. Disk timeout value less than 7 seconds

4-18

4.8 PreRead cache - Enhancing sequential read

throughput

Objective

PreRead cache is used to accelerate the performance of applications that

access data sequentially, such as film, video, medical imaging and graphic

production industries.

With PreRead cache enabled, the RAID controller move to cache the next

blocks of data that will be needed in the sequence. It reads the data from slow,

nonvolatile storage and places it in fast cache memory before it is requested.

Only enable PreRead cache after it has been tested in a read-intensive

application environment by experienced engineer.

Move sequential block

data to RAID’s Cache

in advance

Move Pre-Read data

to Host from RAID’s

Cache

4-19

PreRead menu tree

Follow the steps to configure PreRead function,

Step1: Go to “Main Menu->Array Params->PreRead Setup”, then select

“Enable”

Step2: Select “Max ReadLog” and key in a number, for example: 32

Max Readlog is the record of Read commands that were issued from a

host application.

Step3: Select “Max PreRead” then key in a number for example: 16

Max Preread is the data depth that will be read ahead in advance.

Note: If PreRead is not properly setup, it will decrease the I/O performance of the

RAID system.

4-20

4.9 Alignment Offset – Multipath IO S/W (PathGuard) on

Window OS

Objective

Operating systems (OS) reserves private information, known as a signature

block, at the beginning of a LUN. The result is an un-alignment of disk striping. As

Figure-18 shows, after a physical device is formatted with a file system, a data

segment may cross two stripes causing a split I/O command to complete a read or

write.

Alignment offset is used to set the host logical block address (LBA) alignment

with the stripe boundary of a LUN so that it enhances I/O performance of the RAID

system. In order to fix this problem and enhance system performance under

different operating systems, the LUN should be offset based on its file system type.

Setting alignment offset is recommended when using PathGuard, Maxtronic’s

Multipath I/O software, for Windows operating system.

Upgrading Firmware of the RAID System

The firmware of RAID system can be upgraded via LAN port. Contact Technical

support team for the latest RAID firmware.

Note: Group F/W upgrade will be supported soon.

Step1. Use a serial cable to connect the RS-232 port of the RAID system and the

management console (host computer)

Repeat the same step in Section 3.1.1 – Using the RS-232 serial port to set the

RS-232 serial parameters and start the Hyper Terminal program.

Make sure the connection is linked and logged into the Monitor utility interface.

Step2. Use a RJ-45 cable and set up a connection to the LAN port of the RAID

system and the management console via an ethernet switch

Ex : IP address of console: 10.10.4.85 (FTP server)

IP address of RAID system: 10.10.4.88

2.1 Connect to the RAID system from your management console via an

Ethernet switch

2.2 Set up a FTP server on your console and assign the firmware file path.

For example: Use a freeware FTP server, Tftp32, and select the directory

where the latest firmware is located.

Step3. Login to the Boot Utility Menu of RAID system via terminal program

Reboot the RAID system and while RAID system is self-test, press <Ctrl>+<B>

to enter RAID’s Boot utility interface via Hyper Terminal program.

-III-

Step4.Set IP address of the console and RAID system

In “Boot Utility Menu”, press<N> to set IP address for the console and RAID

system

For example: Local IP address: 10.10.4.88(RAID system)

Server IP address: 10.10.4.85(Console)

Step5. Load firmware image file to the RAID system

Press<L> and then the file name prompt. Type the firmware file name and press

Enter to load image file from the console(FTP server) to RAID system cache.

Note: Make sure the firmware file name and path is assigned and correct.
