One Ethernet controller is integrated on the blade server system board. A controller
provides a 1000 Mbps full-duplex interface for connecting to one of the
Ethernet-compatible I/O modules in I/O-module bays 1 and 2, which enables
simultaneous transmission and reception of data on the Ethernet local area
network (LAN). The Ethernet controller on the system board is routed to a
different I/O module in I/O-module bay 1 or bay 2. The routing from an Ethernet
controller to an I/O-module bay varies according to the blade server type and the
operating system that is installed.
You do not have to set any jumpers or configure the controller for the blade server
operating system. However, you must install a device driver to enable the blade
server operating system to address the Ethernet controller. For device drivers and
information about configuring the Ethernet controller, see the Broadcom NetXtreme
Gigabit Ethernet Software CD that comes with the blade server.
To find updated information about configuring the controller, complete the
following steps.
Note: Changes are made periodically to the IBM Web site. The actual procedure
might vary slightly from what is described in this document.
1. Go to http://www.ibm.com/systems/support/.
2. Under Product support, click BladeCenter.
3. Under Popular links, click Publications lookup.
4. From the Product family menu, select BladeCenter HS12, and click Continue.
Configuring a SAS RAID array
Use this information to configure a SAS RAID array.
Configuring a SAS RAID array applies only to a blade server (machine type 8028)
in which two SAS storage drives are installed.
You can use two SAS storage drives in the blade server to implement and manage
RAID level-0 (striping) or RAID level-1 (mirror) arrays in operating systems that
are listed on the ServerProven list at http://www.ibm.com/servers/eserver/
serverproven/compat/us/. For the blade server, you must configure the SAS RAID
by using the LSI Configuration Utility program.
If an optional expansion unit is installed, you can use it to control all of the SAS
storage drives that are installed in the blade server. Enable this feature by using
the Device and I/O Ports choice in Configuration/Setup Utility program (see
"Configuration/Setup Utility menu" on page 36 for information and instructions).
Important: You must create the RAID array before you install the operating system
on the blade server.
You can use the LSI Logic Configuration Utility program to configure the SAS
storage drives and the SAS controller. To start the LSI Logic Configuration Utility,
complete the following steps:
1. Turn on the blade server (make sure that the blade server is the owner of the
42
BladeCenter HS12 Type 8014 or 8028: Installation and User's Guide
keyboard, video, and mouse). See "Turning on the blade server" on page 13.
