    (ROMB), direct-attached storage (DAS) solution based on the LSI1078ROC (RAID-on-Chip). You can use the ServeRAID-MR10k DIMM to make the system operate in MegaRAID (MR) mode, which uses the MR stack, and the DIMM management and configuration tools. If the ServeRAID-MR10k DIMM is not installed in the system, the LSI SAS1078 operates in the Integrated RAID (IR) mode, which supports RAID levels 0 and 1.

    Integrated RAID (IR), CTRL+C, MegaRAID Storage Manager (MSM), and management utilities cfggen (command line interface) MegaRAID Mode The ServeRAID-MR10k DIMM is used to make the LSISAS1078 adapter operate in MR mode. This mode offers the MR stack, and the MR management and configuration tools. Table 1.2 lists the DIMM features and software features for MR.
