SAN 101 : Host layer

24

Host layer of SAN is made up of server and its components like

• Host bus adapter (HBA)• Host bus adapter drivers• Gigabit Interface Converter (GBIC)• Cables

SAN 101 : Fabric layer

25

Fabric layer is the actual, tangible network part of the SAN. Which moves data around from a source to a destination.

• SAN Hubs• SAN Switches• Data routers• Protocol bridges• Gateway devices• Cables

26

Storage layer consists of all the disk and tape arrays that stores your data

Some of the Key Players in Storage Industry

27

NetApp

28

Lets see what makes

stand out!!

NetApp : Philosophy

29

NetApp believes in one tool for many jobs

Data ONTAP® 

NetApp : Data ONTAP

Based on FreeBSD Unix like operating system

Implements proprietary file-system called WAFL (Write Anywhere File Layout)

Implements proprietary redundancy algorithm NetApp® RAID-DP®

30

Data ONTAP : Features

Data Deduplication & Compression

FilerView Tool

NetApp Flash Pool

NetApp FlexShare

NetApp FlexVol

RAID-DP

NetApp Snapshot

31

NetApp : Protection Software MetroCluster

SnapVault

SnapRestore

SnapLock Compliance and SnapLock Enterprise Software

SnapMirror Data Replication

SnapProtect Management Software

32

33

Let’s have a look at how each of these protection

software work!

NetApp : WAFL

It is implemented similar to log-structured file system

Snapshots is one of the most salient feature of WAFL. It is a read only copy of the file system. This gives raise to a host of software products from NetApp

Supports Unix like file & directory layout for NFS users and Microsoft file & directory layout of CIFS users i.e. Windows and Unix users can use the same networked volumes

34

MyAutoSupport : Icing on the cake

Is a suite of web-based applications hosted on the NetApp support site which helps you Analyse, Model and Optimize your storage

NetApp AutoSupport has to be enabled by the customer/vendor to leverage all the tools in NetApp My AutoSupport

My AutoSupport proactively identifies storage infrastructure issues through a continuous health-check feature and automatically provide a step-by-step plan to avoid disruptions
