Dell PowerVault DL2000 - Manual (Page 16)

PowerVault DL2200 Disk Configurations Running Windows Server 2008 Standard x64
Edition
The PowerVault DL2200 supports SAS and nearline SAS drives only. The operating system resides on a RAID 1
(mirrored) virtual disk located within the system. These disks appear as slots 12 and 13 in Dell OpenManage Server
Administrator. For information on these disks, see the
Dell PowerVault DL2200 Owner’s Manual at support.dell.com/
manuals.
The standard configuration is comprised of hot spare in slot 0, a disk group occupying slots 1 through 5, and a disk group
occupying slots 6 through 11. Automatic disk configuration creates one or more RAID 5 virtual disks on each disk group.
The standard configuration of the optional PowerVault MD1200 storage enclosure is identical to the DL2200’s slots 0
through 11.

PowerVault DL2200 Disk Configurations Running Windows Server 2008 R2
In addition to the RAID 5 standard configuration supported under Windows Server 2008 Standard x64 Edition, the DL2200
and MD1200 storage enclosure support alternative RAID 6 standard configurations, provided the disk subsystem state is
standard. For more information on disk subsystem states, see the topic “Disk Subsystem States”.
The two RAID 6 standard configuration is comprised of a disk group occupying slots 0 through 5 and a disk group
occupying slots 6 through 11. Automatic disk configuration creates one or more RAID 6 virtual disks on each disk group.
The single RAID 6 standard configuration is comprised of a single disk group occupying slots 0 through 11. Automatic
disk configuration creates one or more RAID 6 virtual disks on the disk group. See figure “Dell PowerVault DL2200 and
MD1200 Disk Slots”.
Disk Subsystem States
The disk subsystem state is standard under the following conditions:
• The appliance software stack version must be at version 3.3 or higher.
• Symantec Back Exec must be version 2010 R3 or higher.
If any of the conditions above are not met the disk subsystem state is advanced. After the condition(s) that caused the
disk subsystem state to advance is corrected, the disk subsystem state automatically reverts to the standard state.
NOTE: Under certain circumstances a physical disk failure can cause the configuration state to transition from
advanced to standard. In this case, the disk subsystem reverts to advanced after the failed physical disk is
replaced and the copy back operation is complete.
