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.

OVERVIEW OF THE ServeRAID-MR10k

SAS/SATA CUSTOMIZED ENABLER DIMM

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.

-

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.

Step 5 Open the retaining clip on each end of the

connector.

Step 6 Touch the static-protective package that contains

the DIMM to any unpainted metal surface on the
outside of the server; then, remove the DIMM
from the package.

Step 7 Turn the DIMM so that the keys align correctly

with the slot.

Step 8 Insert the DIMM into the connector by aligning

the edges of the DIMM with the slots at the ends
of the connector.

Important

: Incomplete insertion might cause damage to the

server or the DIMM.

Step 9 Firmly press the DIMM straight down into the

connector by applying pressure on both ends
simultaneously.

The retaining clips snap into the locked position
when the DIMM is seated in the connector.

Step 10 Install the iTBBU in the divider that contains the

battery holder.

Step 11 Install the divider that contains the iTBBU holder

in the server.

Step 12 Route the iTBBU cable through the cable routing

guides on the divider to the DIMM.

Step 13 Insert the battery pack harness at the end of the

cable into the J1 connector on the backside of the
DIMM.
