CONTROLLER INSTALLATION
Perform the following steps to install the ServeRAID-MR10is
SAS/SATA Controller.
Step 1 Unpack the Controller
Unpack the controller in a static-free
environment. Remove the controller from the
antistatic bag and inspect it for damage.
If the controller appears to be damaged, or if the
ServeRAID-MR Support CD is missing, contact
your place of purchase.
The CD contains utility programs, device drivers
for various operating systems, and the following
documentation:

Unit User’s Guide
•ServeRAID-MR Device Driver Installation
User’s Guide
Step 2 Prepare the Computer
Review all safety information provided with the
computer. Unplug the power cords from the
power supplies, disconnect the computer from
the network, and remove the computer cover.
Refer to the documentation provided with the
computer for instructions.
Step 3 Review the Connectors
Figure 1 shows the location of the connectors on
the controller.
Attention: Back up your data before you change your
system configuration. Otherwise, you might lose
data.
Important: When you handle static-sensitive devices, take
precautions to avoid damage from static
electricity.
Attention: Before you install the controller, make sure that
the computer is disconnected from the power and
from any networks.

Table 1 describes the connectors on the
controller.
Step 4 Install the Controller in the Computer
Insert the controller in a PCI Express slot on the
motherboard, as shown in Figure 2.
Press down gently but firmly to seat the card
correctly in the slot. Secure the controller to the
computer chassis with the bracket screw.
Note:Refer to your computer documentation for
information about the PCI Express slot.

SATA Controller
Step 5 Configure and Install the SAS Devices, SATA
II Devices or Both in the Host Computer Case
Configure the SAS devices, SATA II devices, or
both, and install them in the host computer.
Note:The ServeRAID-MR10is controller supports
SATA II protocols but not SATA I protocols. All
references to SATA in this document are to SATA
II.
Step 6 Connect the Controller to the SAS Devices,
SATA II Devices, or Both

connector locations.
Note:Refer to the ServeRAID-MR10is SAS/SATA
Controller User’s Guide for information about the
cables and the connectors.
Step 7 Turn on the Power to the Computer
Replace the computer cover, and reconnect the
power cords. Turn on the power to the computer.
During boot, a MegaRAID BIOS message similar
to the following is displayed:
LSI MEGARAID BIOS VERSION xxxx [date]
Copyright(c) 2007, LSI Corporation
HA-1 (Bus x Dev y) MegaRAID 8708E
PCI-Express RAID Controller
Standard FW xxxx DRAM=xxx MB(SDRAM)
The firmware takes several seconds to initialize.
During this time the controller scans the bus(es).
Step 8 Run the WebBIOS Configuration Utility
Run the WebBIOS Configuration Utility to
configure the physical arrays and the logical
drives. When the message Press <Ctrl><H> for
WebBIOS displays on the screen, immediately
press CTRL+H to run the utility.
Note:Refer to the ServeRAID-MR Software User’s
Guide on the ServeRAID-MR Support CD for
detailed steps on configuring the physical arrays
and the logical drives.
Step 9 Install the Operating System Driver
The controller can operate under various
operating systems. To operate under these
operating systems, you must install software
drivers.
The ServeRAID-MR Support CD includes drivers
for the supported operating systems. You can
view the supported operating systems and
download the latest drivers for the controller at
http://www.ibm.com/systems/support/.
Refer to the ServeRAID-MR Device Driver
Installation User’s Guide on the CD for details on
installing the driver. Be sure to use the latest
Service Packs provided by the operating system
manufacturer and review the readme file that
accompanies the driver.
SUPPORTED RAID LEVELS
The ServeRAID-MR10is SAS/SATA Controller supports disk
arrays using the following RAID levels:
•RAID 0 (Data striping): Data is striped across all disks
in the array, enabling fast data throughput. There is no
data redundancy. All data is lost if any disk fails.
•RAID 1 (Disk mirroring): Data is written simultaneously
to two disks, providing complete data redundancy if one
disk fails. The maximum array capacity is equal to the
available size of the smaller of the two hard drives.
•RAID 5 (Disk striping with distributed parity): Data is
striped across all disks in the array. Part of the capacity
of each disk stores parity information that reconstructs
data if a disk fails. Provides good data throughput for
applications with high read request rates.
•RAID 6 (Disk striping with distributed parity across
two disks): Data is striped across all disks in the array
and two parity disks are used to provide protection
against the failure of up to two physical disks. In each row
of data blocks, two sets of parity data are stored.
•RAID 10 (RAID 1 and RAID 0 in spanned arrays): Uses
mirrored pairs of disks to provide complete data
redundancy. Provides high data throughput rates.
•RAID 50 (RAID 5 and RAID 0 in spanned arrays): Uses
both parity and disk striping across multiple disks to
provide complete data redundancy. Provides high data
throughput rates.
•RAID 60 (RAID 6 and RAID 0 in spanned arrays): RAID
60 uses both distributed parity across two parity disks and
disk striping across multiple disks to provide complete
data redundancy. RAID 60 provides high fault tolerance.
TECHNICAL SUPPORT
Refer to the Warranty and Support Information document for
information about the technical support available for this
product.
Attention: The battery in the iBBU must charge for at least
six hours under normal operating conditions. To
protect your data, the firmware changes the Write
Policy to write-through until the battery unit is
sufficiently charged. When the battery unit is
charged, the controller firmware changes the
Write Policy to write-back to take advantage of
the performance benefits of data caching.
