Note: xSeries 255 supports the IXA Adapter (P/N 1519100) for connection to iSeries models for Windows 2000 Server and Advanced Server. Installation is restricted to slot two and
Remote Supervisor (P/N 09N7585) must be installed.
Bays (Total/Avail) 8
1. Ships with standard keyboard and mouse. See Power, Monitors and Accessories section for tower-to-rack conversion kit.
2. Housed in a 19in rack-mountable drawer and ships standard without a keyboard or mouse. See Rack Cabinets and Options section for supported IBM racks.
3. Intel Xeon MP processor with integrated full-speed ECC L3 cache and 400MHz (quad-pumped) access to memory and I/O buses. Processors in models 7 ... 9RX are not compatible
with processors in models 4 ... 6RX.
4. Advanced Chipkill ECC memory corrects two-, three-, and four-bit memory errors. Standard memory supports two-way interleaving. Two or four optional RDIMMs are installed in pairs
to support two-way interleaving (up to a total of six RDIMMs). Four-way interleaving is supported with the selection of two optional RDIMMs and selection of an additional four or eight
RDIMMs in groups of four. Hot-spare memory is supported for both two-way interleaving (up to six RDIMMs) and four-way interleaving (see Memory section). Four-way interleaving
outperforms two-way interleaving. Memory options must match in density and technology in order to support interleaving and hot-spare memory. Maximum memory is based on 12
2GB RDIMMs. When 2GB RDIMMs are installed, the BIOS and diagnostic firmware must be later than version 1.02.
5. Two optional 370w Reversed Fan Hot-swap Redundant Power Supplies (P/N 31P6133) are required to support N+N redundancy. Refer to the Power section in xSeries 255 Power,
Monitor & Accessories for additional information.
6. Maximum internal HDD storage capacity is based on 12 hot-swap 146.8GB HDDs, which requires optional 6-pack Ultra320 Hot-swap Expansion Kit (P/N 32P8163). Both the standard
and optional hot-swap HDD backplanes are Ultra320, but only Ultra160 HDDs are supported.
7. Variable read rate. Actual playback speed will vary and is often less than the maximum possible.
8. Total number of bays includes the standard bays plus six additional bays provided by installation of optional 6-pack Ultra320 Hot-swap Expansion Kit (P/N 32P8163).
