Chapter 20. System x3950 and xSeries 460 249
2. These processor options support up to 32-socket (64-cores) SMP applications in the System x3950 and
xSeries 460.
3. The System x3950 and xSeries 460 can be expanded only to a two chassis 8-way configuration, four
chassis 16-way configuration, or an eight chassis 32-way configuration by connecting xSeries MXE-460
servers. The two chassis 8-way configuration requires a x3950 or x460 and one MXE-460. The four chassis
16-way configuration requires a x3950 or x460 and three MXE-460 servers. The eight chassis 32-way
configuration requires a x3950 or x460 and seven MXE-460 servers.
4. The xSeries MXE-460 server is functionally identical to the System x3950 and xSeries 460 servers and
supports the same hardware configurations, however it is supported only as an expansion module to a
base System x3950 or xSeries 460 and not in a stand-alone configuration. MXE-460 ships with two empty
4-slot memory expansion cards (13M7409) and two power supplies as standard.
5. On the 8874-1RY MXE-460 the following processor options can be installed: 13N0715, 13N0714, and
13N0713.
6. On the 8874-2RY MXE-460 the following processor options can be installed: 25R8941 and 25R8942.
7. The two chassis 8-way configuration requires two 2.3m scalability cables to interconnect the x3950 or
x460 with one MXE-460.
8. The four chassis 16-way configuration requires three 2.3m scalability cables and three 2.9m scalability
cables to interconnect the x3950 or x460 with three MXE-460 servers.
9. The eight chassis 32-way configuration requires six 2.3m scalability cables and six 2.9m scalability cables
to interconnect the x3950 or x460 with seven MXE-460 servers.
