Business As Usual?

• It is cheaper to buy new rather than optimize existing – We’ll dispel this by showing you your own numbers

• Budgets crimped; storage professionals asked to “domore with less”

– We’ll show you how to squeeze every last bit out of your existing equipment and show you how to makethe right investments going forward

• Storage is “too complicated”

– It’s hard work, but not too complicated when you havethe right tools and the right partner



How Did We Get Here?

• Everyone has the best interest of the business in mind;not always the right approach however

• Running out of storage is BAD! Overcome your fears

• The “doubling” factor and other math problems

• Old School: Take all you want – just don’t try to give anyback

• John Madden obvious – “We’re not hoarding; We’re justtaking extra to make sure we don’t run out.”

• “I can buy a terabyte disk for xx dollars at Best Buy…” -It’s not just the disk!



Storage UtilizationWhat is your REAL storage utilization?

• Ask three internal sources, get three different answers (Our Case Studyexplains why all three can be right and wrong at the same time)

Why?

• Everyone is “missing” data; nature of Storage design• Lack of inter-department communications• No tools, ineffective tools, inaccurate tools• “Special case” data collection problems – VMWare, Microsoft Hyper-V,

Linux Zen, AIX LPAR’s, Solaris Zones, clustering, raw volumes• Under the restrictions of last decade’s technologies

• Simply not easy to measure and harder to fix utilization issues• Not anyone’s problem; is *everyone’s* problem



Case StudyXYZ Corporation: Understanding REAL Storage Utilization

• Case Study reflects real results from manypast engagements – not a worst casescenario

• XYZ Corporation – A single data center

– A mixture of storage from many

manufacturers – Experiencing moderate storage growth drivenby new applications, video capture new datawarehousing projects

Case Study: Orphaned StorageThe Storage Manager’s View

• Most basic form of storage reclamation: Orphaned StorageReclamation• Occurs when servers physically move or disconnect from the

storage network and no one notifies the storage team• 10-15% of a data center’s capacity can be tied up in orphaned

storage at any given moment

• Easy to identify with simple SRM reporting• Each instance must be investigated to insure the storage is reallyorphaned; servers that are powered off can look like they haveorphaned their storage

• Orphaned LUN reclamation needs to be part of standard operationsand performed either weekly, monthly or quarterly

• Best case scenario is server teams notify storage when movingservers (via work order, service request or other mechanism)



Case Study: Orphaned StorageThe Storage Manager’s View

• Note that Allocated Storage decreases and orphaned diskbecomes available disk

• Utilization drops to 73% from 83%

File System/Directory

Description

/SID/arch File system for database archive logs.

/SID/backup File system for database backup files. This partition is currently only created for the Production instance.

/SID/oracle File system containing the Oracle database binaries and configuration files

/SID/oradata File system containing data01, data02 and data03 directories.

/SID/oradata/data01 All data files except system and temp data files. For example, data files for Oracle Portal, Oracle Files,e-mail, tools, and so on. These are mainly the *data*.dbf , *idx*.dbf , and control01.ctl files.

/SID/oradata/data02 Contains the system and temp files. These are mainly the system*.dbf , temp*.dbf , andcontrol02.ctl files.

/SID/oradata/data03 Log files only. These are mainly the log*.dbf , and control03.ctl files.

Case Study: Storage UtilizationThe Server Admin’s View

• LUN’s are used by Server Admin to create file systems

Archive Logs

Backup

Oracle Program Files

Oracle Data

Reserve

• Standard practice thatsome LUN’s held in“reserve” for future growth

Case Study: Storage UtilizationReserve LUN’s

• 20-50% of your storage can be tied up on “reserve”LUN’s

• Convenient for Server Admin, expensive for theorganization

• A practice born from distrust or lack of design – fear storage won’t be there when needed; fear thatstorage team can not execute quickly enough

• “It’s not hoarding, I am just keeping a little extra incase I need it.”

• Can be fixed with good engineering design, finelytuned operations and open communications betweenstorage and server admins



Case Study: Reclaimed ReserveThe Storage Manager’s View

• Note that Allocated Storagedecreases and orphaned diskbecomes available disk

• Utilization drops to 73% from83%

Case Study: File System UtilizationFilesystem Data

• Typical average file system utilization acrossan organization is 30%

• Some file systems contain more disk than

needed for performance reasons (morespindles)

• LUN size is important; a variety of small,medium and large LUN’s is best

• “Right sizing” is difficult without any history or accurate data regarding growth

Analysis Steps



Case Study: ConclusionsOpportunities

• Reclaim orphaned LUNs• Reclaim reserve LUNs

• Reclaim unused allocations

• Shrink filesystem data

• “Re-platform” servers with “right sized” disk allocations• Move non-critical data to secondary tier of disk

• Create storage friendly policies and procedures thatprevent over allocation and misuse of disk

• Examine technologies that can help prevent futureissues with disk allocations: thin-provisioning, storagevirtualization, tiered storage



The MSI OfferingStorage Efficiency & Optimization: Stair Step Approach

Data Collection

Analysis

Remediation

Notification

Prevention



The MSI Offering• Storage Efficiency & Optimization Review engagement

that requires no new hardware or software investment• Stair step approach

• Goal of letting the customer choose how muchinvolvement they want

• Data Collection usually completed within several weeks;Other steps are dependant upon the size of theenvironment and the number of optimizationopportunities uncovered in Data Collection; typically four to eight weeks

• Installation and temporary use of MSI SRM tool as partof overall offering is required; software removed uponcompletion of engagement

• Project management included throughout each step



Policy Changes• Must be top down; lateral policy implementation is

ineffective• Must be a common understanding between departments

why a policy is in place; the policy is for the commongood of the company

• Must provide alternative means of accomplishing

business goals if a new policy negates long standinghabits/processes

• Must be enforceable and monitored• When appropriate, consider historical data in formulating

or modifying policies• Continue to review and fine tune policies over time; is not

a “one and done” activity



What is the Opportunity?

• Simple math; if 80% allocated can be reduced to20% allocated the environment can double twicewithout any new disk purchases

• The three year total cost of one PB of Enterprise

Storage is $10 million*; shrinking from 80%allocated on one PB to 20% allocated allows for 4x growth and avoids growth to 4PB – netsavings or 3 x 15 million equals $30 millioncost savings over three years

* Conservative estimate based on standard industry pricing. Please use your own cost numbers to

calculate your own savings – most likely the savings potential will be HIGHER!



Conclusions• MSI engagement can potentially save companies

millions on storage purchases; Potential for HUGEpayback

• Will highlight what storage team is doing right and helpremediate what needs additional work

• Helps in implementing policies that can prevent futureproblems/issues

• Because MSI has expertise and experience in theseengagements they can be accomplished quickly andquietly in an organization; potential for some “quick

wins”
