Extensions and conversions
Additional processors
The system board can be upgraded to include up to four processors. You may
only use processors of the same type on the system board. All processors must
have the same frequency and cache size.
The system board can also be upgraded to dual-core processors.
Extension of the main memory
The system board offers slots for four hot-plug memory boards, each of which
can accommodate up to four memory modules (in two memory banks) The slots
are suitable for DDR II/400 MHz DIMM modules with 1 GB, 2 GB and 4 GB
capacity. The board supports a maximum memory configuration of 64GB.
Additional accessible drives
In addition to the existing CD/DVD drive, two tape drives are available as acces-
sible drives. The drives are installed in the server using module frames. The
bays for the tape drives are designed for 5.25 x 1.6-inch devices.
Additional controllers in non-hot-plug PCI slots
The system board has seven PCI slots:
●
Slots 1-5 are hot-plug PCI slots which can be fitted with hot-pluggable
controllers (the hot-plug PCI slots are described in the operating manual).
●
Slots 6 and 7 are 100 MHz non-hot-plug PCI slots and can be fitted with
boards with a maximum length of 315mm.
Additional external SCSI interface
If you want to connect additional external SCSI devices, one channel of the
onboard controller can be made available for connecting storage subsystems
via the external SCSI interface.
Battery (BBU) for the RoMB controller
An optional battery (battery backup unit = BBU) is available for the internal
RoMB controller to protect its memory contents in the event of a power failure.
