7. Understand the Current State
• Discovery of all your storage assets
– Storage assets: fabric and arrays
– Host assets: virtual machines, databases, applications
• Single view of full storage stack from application to spindle
– Understand dependency of application on infrastructure elements
– Dynamic update of changes
Results
• Foundation for everything else: you can’t improve what you can’t see
• Provides the visibility needed for capacity management and tiered storage
• Builds organizational transparency

8. Storage Capacity Management
• Asset Management
– Unified view of SAN, NAS, DAS, and host assets
– Lifecycle management and relationship tracking
• Storage Consumption Analysis
– “Waterfall” view of consumption at each level
– Classification of file-level data
• Storage Optimization
– Storage reclamation and file migration decisions
– Purchase the appropriate amount of storage
Results
• Reduction in capital expenditure
• Better decision-making and procurement planning

9. Stop Buying Storage

amount of terabytes that they installed in 2008”

13. Adopt Thin Provisioning
Adopt Thin Provisioning
“Thin provisioning or data reduction, data
compression, deduplication, and single
instance store, can greatly reduce storage
growth and may actually allow us to not
purchase any storage for a year.“

15. Thin Provisioned Storage
Challenges Innovations
• Thin provisioning alone isn’t • Thick to thin migration
enough • Storage reclamation
• Improving storage capacity • Getting & staying thin
utilization
• Thin aware file systems and
volume managers
15

16. Organizational Benefits of “Thin”
Provisioning
• Delay storage capacity upgrades
– Increasing efficiency from 35% to 70% may delay hardware purchases
for a year or more
• Reduce software license fees and maintenance costs
– License fees and maintenance are tied to total capacity, used or not
• Reduce provisioning labor
– Thin volumes grow automatically
• Maintain SLAs
– Thin provisioning has no negative effect on performance or availability
• Reduced total storage reduces environmental needs
– Power/cooling go hand-in-hand with capacity

17. Wandering File Systems….
• Thin Storage is ‘Write Once, Allocate Forever’
– A file created triggers allocation. A file deleted does nothing
– Another file created, if on brand new blocks, triggers allocation
• File systems differ in their ability to reuse ‘free’ space

• Thin Storage is ‘Write Once, Allocate Forever’
– A file created triggers allocation. A file deleted does nothing
– Another file created, if on brand new blocks, triggers allocation
• File systems differ in their ability to reuse ‘free’ space
• Veritas File System aggressively recycles freed space
• Minimizes unnecessary space allocation in array

19. Optimize Thin Provisioning on Windows
• Veritas File System is very thin friendly on Unix and Linux
• However Windows (NTFS) behaves very differently
– NTFS is OK at creation time
– NTFS has a strong tendency to wander across entire volume
– Known problem in the industry documented by storage vendors
• Veritas Storage Foundation Windows can automate the
management of NTFS on the underlying storage volumes
– Ensure storage teams benefit from high thin storage utilization
– Don’t increase operational burden on server teams
– With dynamic volumes, growth can be automated and dynamic

20. Challenge of Migrating to Thin Storage
• Migrating online typically involves FULL ‘block level’ copy to Thin Devices
– Effectively writes across entire TP mirror, causing full allocation
– If volume 1 is 100 GB with 30 GB used, 100 GB will be allocated to thin volume 2
• This applies to ALL block level copy methods (Host, Network, Appliance, Array)

21. Migrate Online and Reclaim Storage
• SmartMove allows online reclamation as you migrate to Thin Storage
– When mirroring, SmartMove only copies useful blocks
• SmartMove is hardware independent and works with ALL thin storage
• Industry’s only solution for online thick to thin conversions
SF Host (Unix, Linux, Windows)
VxFS / NTFS

22. Need to Optimize
Thin Storage Over Time
• Ability to reclaim ‘no longer used’ thin storage is needed
• SmartMove provides a great starting point
• VxFS and SFW minimize unnecessary allocations...
• … BUT unnecessary allocations are caused by applications
• Only the host can differentiate between free and used blocks
– Hardware tools do not provide sufficient insight
Used space File deletions SF Thin
in large VxFS file reduce VxFS Reclamation
