Superserver Ks series


System

The Fujitsu Superserver Ks is a development of the earlier Teamserver Hs, expanded to provide a faster memeory bus, more CPUs, more I/O slots, memory, and storage capacity. It is a slightly more distant descendant of the ICL DRS-6000.

The Superserver Ks has 4 slots for MBus modules, and is capable of using HyperSPARC modules (so it is not an XBus/XDBus system), and thus must have either:

or

As for the MBus speed, it could be any of:

Due to firmware and the I/O bus structures beyond the MBus, the Superserver Ks does not run SunOS 4.x or Solaris, but runs an ICL multi-processor derivation of UNIX SVR4.2 called DRS/NX.

The standard Ks models are:

All models use the same chassis, CPU/memory boards, I/O boards, etc.

The K42Xs models can be upgraded with SM71 or HM142S-1024 modules, as long as the required PROM upgrade is applied at the same time.

The K47Xs models can be upgraded to HM142S-1024 modules, as long as the required PROM upgrade is applied at the same time.

Presumably, the Ks series (and the O/S, NX) can use any single-width HyperSPARC modules with the possible exception of modules equipped with RT620D CPUs.

Similarly, I would expect that the SM71-capable members of the Ks series could also use SM81 modules but, of course, this is neither proven nor supported.

Finally, I would also expect that all members of the Ks series can use all SM61 modules with the possible exception of Sun part number 501-2571.

As I know so little about these systems, I cannot advise on exactly which SM51 modules work, the specific firmware revisions needed to support the SM71 and HyperSPARC modules, the set of unsupported but useable MBus modules, or any other issues not covered above.
