So lt looks like we are migrating our University to a murder setup. We are
about 50,000+ users, with currently a number of mailstores (UWash) and
users directly addressing them.
We are looking towards adding new hardware for an MUPDATE box and some
frontends. Anyone have recommendations on these? Sparc/Solaris versus
X86/Linux? single-CPU versus duals? storage?
I poked around in the mailing lists, didn't find anything really current.
And we all know how our users email usage has gone up in the last couple
of years.
We are running a Cyrus murder with 2 frontends, 2 backends, and 1 mupdate
master for approximately 30,000 users (although actual usage varies
greatly). The frontends and mupdate master are Dell 2850s with dual 3GHz
Intel Xeons. In general, the frontends and mupdate master are pretty
bored. You can view the performance graphs for these servers at:

These servers have Dell's hardware mirroring for 2 internal drives, which
seems to be more than sufficient. I'm a big fan of dual-core and/or
dual-cpu solutions regardless of the size of the server. Usually the
price difference is negligible. Personally, I would buy the new low-power
Intel Xeons or AMD Opterons if I were purchasing these servers today.
