Installing a SAS hard disk drive
The blade server has two connectors on the system board for installing optional
SAS hard disk drives within the blade.
All SAS connectors are on the same bus. 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 array.
Note: Do not install a rear SAS hard disk drive in SAS connector 1 if you intend to
install an optional standard-form-factor expansion card. The standard-form-factor
expansion card occupies the same area as the second hard disk drive.
Figure 13 shows how to install the rear SAS drive. The procedure is nearly
identical for the front drive.

To install a SAS hard disk drive, complete the following steps:
1. Read "Safety" on page v and the "Installation guidelines" on page 239.
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 a
BladeCenter unit" on page 241.
3. Carefully lay the blade server on a flat, static-protective surface, with the cover
side up.
4. Open and remove the blade server cover. See "Removing the blade server
cover" on page 244.
5. Locate the SAS connector for the hard disk drive.
