The ServeRAID-MR10k SAS/SATA Customized Enabler
DIMM is designed for use in the System X 3950 M2 and
3850 M2 servers. The ServeRAID-MR10k DIMM offers a
flexible RAID-on-motherboard (ROMB), direct-attached
storage (DAS) solution based on the LSI1078ROC.
Using the ServeRAID-MR10k DIMM enables the system to
operate in MegaRAID (MR) mode, which uses the MR stack,
and the MR management and configuration tools. If the
ServeRAID-MR10k DIMM is not installed in the system, the
LSI1078ROC operates in the Integrated RAID (IR) mode,
which supports RAID levels 0 and 1.
The ServeRAID-MR10k SAS/SATA Customized Enabler
DIMM consists of two pieces:
• A Customized 240-pin DIMM module that includes a
RAID key, which contains hardware needed to use
advanced MegaRAID features
• A remote intelligent transportable battery backup unit
(iTBBU)
Figure 1 displays the Customized 240-pin DIMM module that
contains the RAID key. The J1 connector on the back of the
DIMM connects by cable to the remote iTBBU.

The iTBBU protects the integrity of the cached data on the
ROMB controller by providing backup power if there is a
complete AC power failure or a brief power outage. For more
information about the battery, refer to the ServeRAID-MR10k
User's Guide on the ServeRAID-MR Support CD.
Figure 2 displays the iTBBU that connects by cable to the
DIMM module.

Attention: The battery in the iTBBU must charge for at least
six hours under normal operating conditions. To
protect your data, the firmware sets the Write
Policy to write-through until the battery unit is
sufficiently charged. When the battery is charged,
the RAID DIMM changes the Write Policy to
write-back to take advantage of the performance
benefits of data caching.
