enables simultaneous transmission and reception of data on the Ethernet local area
network (LAN). The Ethernet controller on the system board is routed to
I/O-module bay 1 or bay 2. The logical link of each Ethernet port to an
I/O-module bay is assigned by the operating system.
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, go to http://www.ibm.com/

Creating an array using the ServeRAID H1135 configuration utility
Use these instructions to create an array using the ServeRAID H1135 configuration
utility.
Use the LSI Configuration Utility program to configure and manage redundant
array of independent disks (RAID) arrays. Be sure to use this program as described
in this document.
The integrated SAS/SATA controller with RAID capabilities supports RAID arrays.
You can use the LSI Configuration Utility program to configure RAID 1 (IM),
RAID 1E (IME), and RAID 0 (IS) for a single pair of attached devices. If you install
the optional ServeRAID H1135 SAS/SATA controller, it provides RAID levels 0, 1,
and, 10 support. If you install a different type of RAID adapter, follow the
instructions in the documentation that comes with the adapter to view or change
settings for attached devices.
In addition, you can download an LSI command-line configuration program from
http://www.ibm.com/supportportal/.
When you are using the LSI Configuration Utility program to configure and
manage arrays, consider the following information:
v The integrated SAS/SATA controller with RAID capabilities supports the
following features:
– Integrated Mirroring (IM) with hot-spare support (also known as RAID 1)
Use this option to create an integrated array of two disks plus up to two
optional hot spares. All data on the primary disk can be migrated.
– Integrated Mirroring Enhanced (IME) with hot-spare support (also known as
RAID 1E)
Use this option to create an integrated mirror enhanced array of three to eight
disks, including up to two optional hot spares. All data on the array disks
will be deleted.
– Integrated Striping (IS) (also known as RAID 0)
Use this option to create an integrated striping array of two to eight disks. All
data on the array disks will be deleted.
v Hard disk drive capacities affect how you create arrays. The drives in an array
can have different capacities, but the RAID controller treats them as if they all
have the capacity of the smallest hard disk drive.
v
If you use an integrated SAS/SATA controller with RAID capabilities to
configure a RAID 1 (mirrored) array after you have installed the operating
system, you will lose access to any data or applications that were previously
stored on the secondary drive of the mirrored pair.
