Disk On Module (DOM)

The Storage System SSR212MA ships with a single 512 MB Disk On Module (DOM)

installed directly to the SSR212MA baseboard's IDE connector. The DOM is a storage

device based on flash memory technology, which emulates an ordinary magnetic hard disk

drive.

The DOM is segmented into two 256 MB useable redundant areas. The OS and SAN

Application Software resides on one 256 MB block, while the other 256 MB area is reserved

for upgrades. In the event of a catastrophic failure while performing an OS/SAN Application

Software upgrade, the system will automatically boot from the previously known good

image.

NOTE:

The DOM contains the Storage System SSR212MA OS and SAN Application software, and should never be removed

from the IDE connector while the system is operational, or data corruption could occur.

For more information on how to upgrade the Storage System SSR212MA SAN Management Software, please refer to the

Intel® Storage System Software Manual available from Intel Business Link (IBL) or your Intel sales representative.

WARNING – Like any IDE device, the DOM should not be removed from the IDE connector with

power applied or damage to the DOM could occur.
