Installing a SAS hard disk drive
The blade server has two connectors on the system board for installing optional
SFF SAS hard disk drives.
Depending on the blade server model, at least one SAS hard disk drive might
already be installed. If the blade server is equipped with one SAS hard disk drive,
you can install an additional SAS hard disk drive. These two SAS hard disk drives
can be used to implement and manage a redundant array of independent disks
(RAID) level-1. See “Configuring a RAID array” on page 47 for information about
SAS RAID configuration.
The following illustration shows how to install a SAS hard disk drive.

Note: Do not install a SAS hard disk drive in SAS connector 1 (SAS ID 1) if you
intend to also install an optional standard-form-factor expansion card. The
standard-form-factor expansion card occupies the same area as the second
hard disk drive.
To install a SAS hard disk drive, complete the following steps:
1. Read the safety information beginning on page v and “Installation guidelines” on
page 21.
2. Shut down the operating system, turn off the blade server, and remove the
blade server from the BladeCenter unit. See “Removing the blade server from
the BladeCenter unit” on page 22 for instructions.
3. Carefully lay the blade server on a flat, non-conductive surface.
4. Open the blade server cover (see “Opening the blade server cover” on page 23
for instructions).
5. Locate SAS connector 0 or SAS connector 1.
Attention: Do not press on the top of the drive. Pressing the top could
damage the drive.
6. Put the drive into the tray and push it, from the rear edge of the drive, into the
connector until the drive moves past the lever at the back of the tray.
7. If you have other options to install or remove, do so now; otherwise, go to
“Completing the installation” on page 34.
