Does anyone have a lead on non-DCS Dell c6100 servers? I'm hunting for either barebones units or units with six-core chips like the L5639.
They appear to be getting scarce, but the prices are still good. I found (and bought) a pile of them with 8x L5639 CPU and 96GB RAM for %1,400 each.
At this point they are starting to look slow, but if your power costs are reasonable, and you buy used, they are still very hard to beat when measured in terms of compute power per dollar all costs included. When the 6-8 core Xeon E5 CPUs drop to $200 each then I will switch.
This particular purchase is probably out of scope for the STH list, but it's a fun one for me. I'm adding almost 3,000 CPU cores to my existing processing cluster, shifting 3.4 of the work from AWS to private colo. Call it "hybrid cloud".
