When you create logical drives in ICP Storage Manager, you can assign a RAID level to protect
your data.
Each RAID level offers a unique combination of performance and redundancy. RAID levels
also vary by the number of disk drives they support.
This chapter provides a comparison of all the RAID levels supported by ICP Storage Manager,
and provides a basic overview of each to help you select the best level of protection for your
storage system.
