Installing internal drives
If you add different types of drives, your system can read multiple types of media
and store more data. Several types of drives are available, such as:
v
Diskette
v
Hard disk
v
CD-ROM
v
DVD-ROM
v
Tape, including digital linear tape (DLT), super digital linear tape (SDLT), and
linear tape-open (LTO)
Note: The server supports both internal and external tape drives.
Your server contains hardware that enables you to replace a failed hard disk drive
without turning off the server. Therefore, you have the advantage of continuing to
operate your system while a hard disk drive is removed or installed. These drives
are known as
hot-swap drives.
Each hot-swap drive has two indicator LEDs (see “Server controls and indicators”
on page 4). If the amber hard disk status LED for a drive is lit continuously, that
individual drive is faulty and requires replacement. When the hard disk drive status
LED indicates a drive fault, you can replace a hot-swap drive without turning off the
server.
Each hot-swap drive that you plan to install must be mounted in a hot-swap-drive
tray. The drive must have a Single Connector Attachment (SCA) connector.
Hot-swap-drive trays come with hot-swap drives.
