Well, if I'll tell you that we still have a 7009-C10 (POWERPC-601),
still running with all originals parts except for memory upgrade, with
RAM modules taken from CISCO router, since 1995, and Model 390
(POWER2) bought in 1995 as well, as our test server for applying
PTFs/perl-dbi development and DNS/proxy server resopectively, the
whole RS6K line would seem a pretty stable platform.

In fact, we had more trouble with later machines, 7025-6F0 (sort of a
successor to F50?) - had to upgrade RAID controller firmware and
system firmware to prevent crashes.

As to ULTRA3 controllers we bought for F50, they are as follows:

root@dbsrv01-313-> lscfg -vp -l scsi3
