IBM ServeRAID M5025 User manual

Thank you for purchasing the ServeRAID M5025 SAS/SATA
controller. Please take a few minutes to read this Quick
Install Guide before you install the controller. For more
information about any topic covered in this guide, refer to the
other documents on your ServeRAID M Documentation CD.
Note:Record your controller serial number in a safe
location in case you need to contact IBM.
The ServeRAID M5025 SAS/SATA controller (Serial-
attached SCSI/SATA) is a PCI Express 2.0, low-profile RAID
controller based on the SAS2108ROC, which is a SAS/SATA
RAID On-a-Chip device. The controller controls eight
external 6-Gb/s SAS/SATA ports through two SFF-8088 x4
Mini SAS external connectors.
The ServeRAID M5000 Series Battery Assembly can be
mounted directly to the controller using a daughtercard or
remotely using a cable.
You can use the ServeRAID M5000 Series Advanced
Feature Key to enable support for RAID 6 configurations and
self-encrypting disks (SED).
For more information about this controller, the iBBU, and the
key, refer to the ServeRAID M5025 SAS/SATA Controller
User’s Guide on the ServeRAID M Documentation CD.
Note:SATA II is the only type of SATA supported by
this controller.
SERVERAID M5025 CONTROLLER
INSTALLATION
Perform the following steps to install the 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 M Documentation CD is missing,
contact your place of purchase.
For the utility programs and the device drivers for
the operating systems, go to the following

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.
See the documentation provided with the
computer for instructions.
Step 3 Review the Connectors
Figure 1 shows the location of the connectors.
Attention: Back up your data before you change your
system configuration or you could lose data.
Important: When you handle static-sensitive devices, take
precautions to avoid damage from static.
Attention: Before you install the controller, make sure that
the computer is disconnected from the power and
from any networks.

ServeRAID M5025 controller.
Table 1 Jumpers and Connectors
Note:J6A1, J6A2, and J6A3 are behind the iBBU when
it is installed directly, but they are still accessible.
Step 4 Install the Controller on the Motherboard
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:This is a PCI Express x8 card and it can operate
in x8 or x16 slots. However, some PCIe slots
support only PCIe graphics cards; if a RAID
controller is installed, it will not function.
Refer to your motherboard guide for information
about the PCI Express slot.

Step 5 Configure and Install the SAS Devices, SATA
II Devices or Both
Configure the SAS devices, SATA II devices, or
both, and install them in the external enclosure.
Note:Refer to the documentation for the external
devices for pre-installation configuration
requirements.
Note:The ServeRAID M5025 controller supports SATA
II protocols but not SATA I protocols. All
references to SATA in this guide are to SATA II.

Connect the cables between the controller and
the SAS devices, SATA II devices, or both. Refer
to the external device documentation to view
connector locations for the external devices.
Note:Refer to the ServeRAID M5025 SAS/SATA
Controller User’s Guide for information about the
cables and the connectors.
Step 7 Turn on the Power to the Computer
Reinstall the computer cover and reconnect the
power cords.
Turn on the power to the computer, making sure
that the power is turned on to the SAS devices
and the SATA II devices before or at the same
time as the host computer. If the power is turned
on to the computer before it is turned on to the
devices, the computer might not recognize the
devices.
During boot, a BIOS message similar to the
following displays:
LSI MEGARAID BIOS VERSION xxxx [date]
Copyright(c) 2010, LSI Corporation
HA-1 (Bus x Dev y) MegaRAID 9260-8i
PCI-Express RAID Controller
Standard FW xxxx DRAM=xxx MB(SDRAM)
The firmware takes several seconds to initialize.
During this time the adapter 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, press CTRL+H
immediately to run the utility.
Note:Refer to the ServeRAID-MR Software User’s
Guide on the ServeRAID M Documentation CD
for detailed steps on configuring the physical
arrays and the logical drives.
Step 9 Install the Operating System Driver
The ServeRAID M5025 controller can operate
under various operating systems. To operate
under these operating systems, you must install
software drivers.
View the supported operating systems and
download the latest drivers for the controller at
http://www.ibm.com/support/en/us. For updates,
click Downloads and drivers. Access the
download center and follow the steps to
download the driver.
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 M5025 controller supports drive groups
using the following RAID levels:
RAID 0 (data striping): Data is striped across all drives
in the group, enabling very fast data throughput. There is
no data redundancy. All data is lost if any drive fails.
RAID 1 (drive mirroring): Data is written simultaneously
to both drives in the drive group, providing complete data
redundancy if one drive fails. RAID 1 supports an even
number of drives from 2 to 32 in a single span.
RAID 5 (drive striping with distributed parity): Data is
striped across all drives in the group. Part of the capacity
of each drive stores parity information that reconstructs
data if a drive fails. RAID 5 provides good data
throughput for applications with high read request rates.
RAID 6 (drive striping with distributed parity across
two drives): Data is striped across all drives in the group
and two parity drives are used to provide protection
against the failure of up to two drives. In each row of data
blocks, two sets of parity data are stored.
Note:The ServeRAID M5000 Series Advanced Feature
Key is required to make RAID 6 configurations on
the ServeRAID M5025 SAS/SATA controller. For
information about the Feature Key, see the
ServeRAID M5000 Series Advanced Feature Key
Quick Install Guide.
RAID 10 (RAID 1 and RAID 0 in spanned groups):
RAID 10 uses mirrored pairs of drives to provide
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.

DISPOSAL OF BATTERY BACKUP UNITS
Warning:If the iBBU is damaged in any way, toxic
chemicals may be released.
The material in the battery pack contains heavy metals that
can contaminate the environment. Federal, state, and local
regulations prohibit the disposal of rechargeable batteries in
public landfills. Be sure to recycle the old battery packs
properly. IBM reminds you that you must comply with all
applicable battery disposal and hazardous material handling
laws and regulations in the country or other jurisdiction
where you are using the iBBU.
For battery disposal instructions, see the IBM Systems
Environmental Notices and User Guide on the ServeRAID M
Documentation CD.
TECHNICAL SUPPORT
Refer to the Important Notices document for information
about the technical support available for this product.
Important: Replace your battery with only the same or
equivalent type recommended by the
manufacturer. For the replacement battery part
number, see the ServeRAID M Problem
Determination and Service Guide on the IBM
Support website.
