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.
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.
4. Supported only in models 1xX, 2xX and 3xX.
5. Supported only in models 4xX, 5xX and 6xX
6. 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.
7. 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.
8. Maximum internal HDD storage capacity is based on 12 hot-swap 73.4GB 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 and are capable of supporting both Ultra320 and Ultra160 HDDs. The entire bus is limited to the speed of the
slowest HDD.
9. Variable read rate. Actual playback speed will vary and is often less than the maximum possible.
10. 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).
