The following sections describe how these HD Ds are configured for each

Four-HDD configu rations
The four HDDs included with the DL100 G2 DP Storage Server (1TB model)
are configured for hardware RAID fault tolerance using the Adaptec RAID
controller. The HDDs are hot-pluggable and hot-swappable. The drives
can be removed and installed with the power on; the Adaptec controller
determines whether a rebuild of a drive is necessary.
The DL100 G2 D P Storage Server (four-HDD) uses Microsoft Disk Man ager
(DM) for managing the logical drives presented to the file system. The
DL100 G2 D P Storage Server (four-HDD) uses all three logical drives as
presented to it from the physical storage layer. The first two logical drives
are used for housing the OS and DON’T ERASE basic partitions. The
third logical drive houses the data volume to be added into the DPM
administration console on a basic partition.
