There are many different devices on which data can be stored. The selection of devices to best meet your storage needs depends primarily on three factors:
Performance
Availability
Cost
You can use Solaris Volume Manager to help manage the tradeoffs in performance, availability and cost. You can often mitigate many of the tradeoffs completely with Solaris Volume Manager.
Solaris Volume Manager works well with any supported storage on any system that runs the SolarisTM Operating Environment.
