Management station—On a management station, MDSM communicates

with the storage array either through an Ethernet connection to the

storage array management port or though an Ethernet connection to a

host server, which passes management information between the

management station and the storage array using FC connections.

Using MDSM, you can configure the physical disks in the storage array into

logical components called disk groups and then divide the disk groups into

virtual disks. Disk groups are created in the unconfigured capacity of a storage

array. Virtual disks are created in the free capacity of a disk group.

Unconfigured capacity comprises of physical disks not already assigned to a

disk group. When a virtual disk is created using unconfigured capacity, a disk

group is automatically created. If the only virtual disk in a disk group is

deleted, the disk group is also deleted. Free capacity is space in a disk group

that is not assigned to any virtual disk.

Data is written to the physical disks in the storage array using RAID

technology. RAID levels define the way in which data is written to physical

disks. Different RAID levels offer different levels of accessibility, redundancy,

and capacity. You can set a specified RAID level for each disk group and

virtual disk on your storage array.

For more information about using RAID and managing data in your storage

solution, see the Owner's Manual at support.dell.com/manuals.
