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

Physical packaging Dedicated rack packaging for enterprise data centers

Modular 2U building blocks that can be housed in existing standard 19” rack alongside servers or other storage

Storage needs at the onset

Larger initial capacity – for immediate needs starting at around 50TB, or

>$150K

Small initial capacity point starting at 1TB and can grow in single drive capacity

increments

Performance management

Provides automatic data distribution to yield even, consistent performance

for all applications

Gives clients the ability to tune and/or tier data placement to maximize performance

across diverse application needs or service levels

13


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

Real-time Compression Implementation

Install Real-time compression appliances in the data path

Configure and test implementation– Network – Set up network transparency – NAS – Add connections to Filers – Compression Filters

Choose data to compress

Begin compressing data

*Run Compression Accelerator–Reduce already stored data

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)
