IBM IntelliStation - ps-2

Part
Number
xSeries 440 provides four drive bays on the lower front panel of the system chassis. At the bottom, two adjacent slim-line bays contain the standard CD-ROM and
a 1.44MB diskette drive. Two 3.5in, SCA-2-compliant slim-line hot-swap hard disk drive bays are located directly above. The IDE CD-ROM is cabled directly to the
IDE port on the planar, and the hot-swap backplane that supports two hot-swap bays is connected to one channel of the dual channel integrated SCSI controller
through a 16-bit LVDS cable.
An optional ServeRAID controller is supported for internal and external RAID applications. An additional, longer 16-bit LVDS SCSI cable is provided standard with
the system to connect the hot-swap backplane to the ServeRAID controller for internal RAID configurations. The integrated controller includes a second channel
that supports external tape enclosures. A 16-bit LVDS cable connects this channel to an industry-standard, 0.8mm VHDCI connector.
For additional information regarding internal cabling, refer to Appendix F: Internal Cabling Overview.

1. Due to four-way interleaving, installation of memory options in banks of four is
required. Banks may be populated in any order. A minimum of four RDIMMs are
required for each SMP Expansion Module (minimum of eight required to enable
memory mirroring).
Notes:
1. See numbering of RDIMM sockets on memory card for bank configuration.
2. Performance is optimized by balancing the amount of memory between ports (and
between SMP Expansion Modules).
3. In order to enable memory mirroring during BIOS set-up, the same memory
configuration must be installed in each port (memory mirroring reduces the amount of
memory available to the operating system by half).
4. Memory mirroring is specific to each SMP Expansion Module, i.e., it is not required in
both the standard and optional CPU/memory boards.

This table does not represent all possible memory
configurations. RDIMMs must be added in sets of four to
support interleaving technology.
1. Network operating systems may limit the maximum
amount of addressable memory. See operating system
specifications for further information.
2. To obtain the quantity of memory identified in the “Total
Memory” column, select the appropriate row and order the
quantity of RDIMMs identified in all columns for that row,
which will be added to the standard memory noted at the
top of the left column.
3. Model 4RY ships with 4GB of memory standard (4 x
512MB RDIMMs installed in each SMP Expansion Module).
4. Optional xSeries SMP Expansion Module (P/N 01R1338)
is required if total RDIMMs exceed 16.
5. Requires removal of standard memory. Installation of
greater than 16 RDIMMs requires optional xSeries SMP
Expansion Module (P/N 01R1338).
