Planning: MD3200 Series Storage Array Terms and Concepts

Only Dell™ supported 6.0-Gbps SAS physical disks are supported in the 

storage array. If the storage array detects unsupported physical disks, it marks 

the disk as unsupported and the physical disk becomes unavailable for all 

operations.

The MD3200 Series array must contain at least two physical disks for proper 

operation. This is necessary because the physical disks are used to store 

configuration information.

The storage array recognizes the physical disk states. Mode and status of 

physical disks are reported in the MDSM application. Possible values for 

mode and status or described in Table 4-1.
