Host server — On a host server system, MDSM and the storage array communicate management
requests and event information using in-band or out-of band-connections.
•
Management station — On a management station, MDSM communicates with the storage array either
through an Ethernet connection to the storage array management port or through an Ethernet
connection to a host server. The Ethernet connection passes management information between the
management station and the storage array connectivity.
Using MDSM, you can configure the physical disks in the storage array into logical components called
disk groups or dynamic disk group 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 physical disks not already assigned to a disk group. When a virtual disk
is created using unconfigured capacity, a disk group or dynamic 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 how
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 dell.com/support/manuals.
