Inescapable Data GrowthImplications for our clients
Inescapable Data Growth– IDC predicts 500% over next 4
years
– Gartner predicts 650% over next 5 years
Inescapable financial motivation for our clients– CAPEX budgets won’t grow like
this to buy capacity
– OPEX budgets won’t grow like this to manage the capacity
Inescapable technology adoption– Clients must be more efficient in data storage
● De-duplication, Compression, Thin Provisioning, Automated Tiering, Archiving
– Clients must stop copying and transmitting backup copies everywhere● Snapshot, Replication
– Clients must make their people more efficient● Automation, Integration

Understanding SVC and Storwize V7000
SVC– Disk virtualization system targeted primarily to large enterprise customers
looking to virtually consolidate storage to reduce cost, improve productivity, improve availability, and gain greater flexibility
IBM Storwize V7000– Midrange disk system targeted primarily to midsize businesses, who will use
it as their principal storage, and large enterprises, who will use it as tier 2 storage or in smaller locations
– Employs advanced storage virtualization technology to deliver high performance, rich software functions, high availability, modular and scalable capacity, and great ease of use
– Also supports virtualization of external storage for nondisruptive data migration or to consolidate and extend the life of existing storage assets

Efficiency FeaturesThin provisioning More productive use of available storage
Across all supported host platforms
Without thin provisioning, pre-allocated space is reserved whether the application uses it or not.
With thin provisioning, applications can grow dynamically, but only consume space they are actually using.

Why Gateway vs. General Purpose Filer Server
Unix Windows Linux
Clients & Servers
.
A single Gateway supports Unix, Linux and Windows file protocols
Potentially reducing the number of servers required for accessing SAN storage in mixed protocol environments
Connecting small inexpensive servers to premium priced SAN storage is very costly.
FC HBAs, FC switch ports… costs could exceed the actual cost of server
A single Gateway extends the reach of SAN storage to many servers attached to an IP network
Potentially reducing overall connection costs
Allowing access to SAN storage at extended distances
A Gateway provides functionality of N series technology to other vendor storage subsystems
A Gateway provides increased protection investment in SAN storage by increasing SAN utilization & accessibility

No Performance Degradation – How? Real-time Compression!Move, Cache and Store Less!
• Real-time Compression Compresses data on initial write
– Less data stored on primary storage (up to 80%) – Much smaller I/O / lower disk workload
• Real-time Compression Compresses data before it gets to the storage array
– Larger effective storage cache (up to 80%) – Array can serve more requests from its read / write cache– Lower storage CPU overhead
• Real-time Compression Does not cause performance degradation
– Reads/Writes are faster due to storage array’s response from cache instead of disk
– Additionally reads may come from Storwize advanced read ahead cache (no write cache)
