changes to the physical storage without impacting host applications. 

● 

Improve storage resource utilization: By combining the storage capacity 
from multiple disk systems into a single pool, SVC uses existing storage 
capacity more efficiently, which can defer additional storage purchases to 
save costs. 

● 

A single, cost-effective set of advanced copy services: SVC can apply 
copy services across all the managed storage, regardless of the disk system 
supplier. This capability helps simplify the environment, reduce the costs of 
implementing disaster recovery solutions, increases flexibility in using stor­
age and increases personnel productivity. 

● 

Create a tiered storage environment: Using virtualization technology, SVC 
enables customers to match the cost of the storage to the value of their 
data. For example, mission-critical data can be stored on high-performance, 
highly available Fibre-Channel disks while non-mission-critical data can be 
stored on serial-ATA disks. Data can easily be moved from one tier to 
another without application disruption. 

Adds value to the storage subsystem solution by providing information for better management. 

Provides a high-performance monitoring tool to help simplify the management of IBM tape subsystems that 
include the IBM TotalStorage Enterprise Tape Library, Virtual Tape Server and Peer-to-Peer Virtual Tape Server 

Provides the ability to monitor and evaluate the performance of a running XRC configuration; the monitor func-

tion provides information at the real-time, historic and summary levels 

Provides automated and central storage management in the z/OS environment 

Provides data access, program and device management functions that furnish effective management of active 
data 

Provides data movement, copy, backup and space management functions 

Provides backup, recovery, migration and space management functions that furnish effective management of 
inactive data 

Provides a policy-driven solution for the management of removable media, such as tape cartridges and reels 

Provides a solution for faster and easier data sorting, reporting and analysis 

Enables batch jobs and IBM CICS® (Customer Information Control Systems) online transactions to update 
shared VSAM data sets concurrently
