HP ProLiant ML310 G3 Data Protection Storage Server - Manual (Page 39)

Physical configurations
Internal storage drives
The two hard drives included with the DL380 G4 DP Storage Server are
configured for hardware RAID fault tolerance using the HP Smart Array
6i RAID Controller. The HDDs are hot-pluggable and hot-swappable. The
drives are configured by default into two logical drives at the controller
level.
The DL380 G4 DP Storage Server uses Microsoft Disk Manager (DM) to
present the 36 GB HDDs to the system as basic disks. The server uses two
logical drives as presented to it from the physical storage layer for the OS
and DON’T ERASE basic partitions. The internal DL380 G4 drives are
configured in a single RAID 5 partition. The non-OS logical drives are
used by DPM and should not be configured using DM.
