Disk Manager; Disk Partitioning And Raid Configuration (Ml110 G1 And Dl100) - HP ML110 G1 User Manual

Disk Manager

The 100 series storage servers use Microsoft Disk Manager (DM) for
managing the various types of disk presented to the file system. Disk
Manager has two types of disk presentations: basic disk and dynamic
disk. Each type of disk has special features that enable different types of
management. The 100 series storage server uses all disks as presented to
it from the physical storage layer.
Disk partitioning and RAID configuration (ML110 G1 and
DL100)
The four hard drives included in the ML110G1 and DL100 storage
