But I suspect that for most purposes, a single CPU with more memory would probably work out better. SMP adds a lot of cost-- you've gotta get P3's or Xenon's, right, not normal P4's, to do SMP, as well as the dual-proc motherboard? > Now I need to choose storage solution for it.

How much disk storage are you going to need? What kind of I/O patterns is the workload going to entail? (What balance of reads and writes, sequential versus random access, etc.) What kind of fault-tolerance and hot-swappability do you need/want? -Chuck To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
