Introduction
Features
SCSI Controller
For operating internal hard disk drives or an internal magnetic tape drive, an
onboard 2-channel Ultra320 LSI SCSI controller is available. Alternatively, an
external storage subsystem (e.g. magnetic tape drive) may be connected to the
second channel at the rear of the server. If both channels are already being
used internally, an additional SCSI controller must be built into a PCI slot.
MegaRAID RoMB Controller
RAID functionality is assured by a MegaRAID controller which is configured as
"RAID on Mother Board" (RoMB) by default. If the server was ordered with the
RAID option, activation of the RoMB controller is performed "ex factory" by
means of an activation key on the system board. RAID levels 0, 1, 10, 5, 50 are
supported. The MegaRAID RoMB controller uses the onboard Ultra320 SCSI
controller by means of a logic specially integrated on the system board.
Optionally, a BBU is available for the RoMB controller to secure memory
contents in case of a power failure.
Accessible Drives/Components
Various mounting locations are available:
–
one location with a LocalView module (standard)
–
one location for a slimline CD or DVD drive (standard)
–
one location for a SCSI 5,25-inch magnetic tape drive (option)
The accessible drives/components integrated in these locations cannot be
replaced while the system is up and running.
Power Supply
The server has two hot-plug power supply units that adjust automatically to any
power voltage in the range from 200 V - 240 V. Thus, redundancy of the power
supply is ensured. If one power supply unit fails, the second unit will maintain
uninterrupted operation. The defective power supply unit can be replaced online
(for further details see section “Replacing a Hot-plug Power Supply Unit” on
page 71).
