Scalability

Enables resource intensive applications torun up to 200,000 I/Os per second.

Offers hot add capability for increasinghardware resources. Enables applications to scale without

disruption or planned downtime.

25/38

StorageManagement

Dynamic storage allocation enables thereduction of storage by >50%.

Uses memory only as required and tracksactual usage for billing. Reduces storage by sharing common user

data. Linksallstorageformanagingcapacityandimprovingperformance

25


26/38

Economics

Cloud data centers can be billed in actualusage increments.

The infrastructure can obtain processingpower from clouds of external vendors. Capacity can be distributed across several

data centers for handling of peak loads.
