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.
See "Configuring a SAS RAID array" on page 47 for information about SAS RAID
configuration.
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 7 shows how to install the rear SAS drive. The procedure is nearly identical
for the front drive.
