Re: Clearly I'm a big fan of "dual" stuff - besides dual PIII/933's I also have 2 Seagate X15 (15,000 RPM) drives. Invites some intriguing configurations.
The X86 MPU systems we've used have never been quite as stable as the uniprocessor systems. I've now seen uniprocessor X86 systems going indefinitely between shutdowns (6 months and more), but the MPU systems never seem to go much more than two or three months without locking up. With single processor systems well over a GHZ, I tend towards the single processor systems. Most programs do most of their work in one thread, and you wind up running at the speed of one processor.
Re: the 15K drives. I've limited things to 10K, so far, going to striping across more spindles if it's needed (but that doesn't help latency). The last workstation I speced had dual 10K drives, RAID 0, off an Adaptec 2100s controller, but I was leery of the 15K drives (no guts, no glory?). What coolers are you using for those 15K drives? I spec dual fan drive coolers for the 10K drives and they still run pretty warm. Have you tried doing a defrag with the case loose, then lifting a panel and putting your hand on one of the drives? Was it no more than very warm?
