• Configure and monitor physical subsystem components such as controllers, physical disks, power
supplies, blowers, and network connections.
• Configure and view controller logs and events.
Controller software
HP StorageWorks Virtual Controller Software (VCS) manages all aspects of storage system operation.
VCS provides scalable capacity on-demand, improves performance, increases disk utilization efficiency,
and allows for easy dynamic storage expansion. VCS is installed on the storage system and is also
included in the VCS for HSV Controller software kit.
