Reserved Disk Space during Configuration

Up to 20.6 MB of disk space is reserved when a hard drive is being

Designating Drives as Hot Spares

Hot spares are physical drives that are powered up along with the RAID
drives and usually stay in a standby state. The hot spare drive should be
larger than or equal to the smallest logical drive. If a hard drive used in a
RAID logical drive fails, a hot spare will automatically take its place and the
data on the failed drive is reconstructed on the hot spare. Hot spares can be
used for RAID levels 1 and 5. Each PERC 3 controller supports up to eight
hot spares.
