SVC With IBM Spectrum Virtualize Transforms Storage

Improving Data Value

Reducing the cost of storing data by increasing utilization and using compression, and accelerating applications to

speed business insights

Increasing Data Security

Helping protect data from disclosure, and enabling a complete high availability

strategy including data and application mobility and full

DR protection

Enhancing Data Simplicity

Data strategy independent of infrastructure choice with tightly

integrated functionality and consistent management across

heterogeneous storage

21

• Improves efficiency of your storage, increasing utilization up to double

• Increases the amount of data you can store, enabling up to 5x as much data to be stored in the same space

• Improves storage performance so you can get more done with your data

• Optimizes storage use by moving data to the most appropriate type of storage based on policies you define with IBM Spectrum Control

Improving Data Value

22

23

Enhancing Data Simplicity

• Improves agility with automated provisioning of storage as it is required by applications, integration with virtualization tools such as VMware vCenter, and easy deployment of new storage technologies

• Consolidates all your storage—no matter the vendor—for simplified management, consistent functionality, and greater efficiency

• Enables flexibility in storage acquisition by supporting common capability across all types of storage so you can mix vendors with ease

24

Increasing Data Security

• Improves data security with software based encryption

• Improves data protection with 5-10x faster rebuild of data following a drive failure with internal flash drives

• Improves data availability with fully duplexed copies of data and automatic switchover across data centers

• Eliminates storage downtime with nondisruptive movement of data from one type of storage to another

Planning for unplanned site failures with Stretched Storage

• Active-active storage does NOT eliminate need for proper unplanned site failure planning

• Active-active storage provides much greater business value from the same infrastructure investment

• Active-active storage achieves more robust recovery
