We are in the midst of licensing the SAS software product for a
server. This is an extremely expensive product, and the charge for a
quad-core machine is tens of thousands of dollars more than for a
dual-core machine. If you are unfamiliar with SAS, it does lots of
sequential I/O and is rarely CPU bound. So we are looking to put
together a high performance machine that uses only a dual-core
processor. I know that dual-core is now usually very low-end (or
laptop) but creative suggestions are welcome. Ideally we would like
PCI-e slots for SAS or SATA controllers so that we can have a lot of
fast local storage.
You might look at something like an older Core 2 Duo E8600, possibly
overclocked. I have an E8400 (actually the Xeon equivalent, due to
availability at the moment I bought it) that's rated for 3.00 GHz but
I've OC'ed it to 3.60 with no difficulty (the limit was probably how
fast I could clock the memory, plus I didn't try for anything more).
Those processors have always overclocked very well.
I bought a Compaq AMD Athlon X2 dual core just under two years ago, it
has never given me a day of trouble. I'm very happy with it.
