So it's time to upgrade my home server a bit. It's currently an AMD Phenom 1090T w/ 16gb ram. Ram is becoming a bit of a bottleneck for what I'm doing, so I want to expand.
It's a 24/7 general purpose (primary NAS) server located in somewhat shared living space (home office), so power consumption and noise are important. Being a NAS, support for LFF SATA drives (min 8, ideally 12) is important.
Cost is a concern, but mostly from a value perspective. I don't mind paying an extra $100-200 or more for something substantially better.
After catching up on some research, I was leaning pretty heavily towards getting an R510 w/ L5640s. After seeing some numbers for power usage of those though (150w+), I decided that it would be worthwhile to step up to the next generation and get something from LGA2011.
Making this decision has opened up 2 somewhat orthogonal questions:
1. Is Ivy Bridge worth price premium over Sandy bridge? E5-2670 seems pretty comparable perf wise to E5-2650v2, at a 50% price premium ($100ish versus $150ish). This probably seems worth it, is it?
2. Dual socket versus single socket. The last time I upgraded this proc was back in 2011, so I tend to hold onto things for some time. Going a little overkill now with like dual 8-core will hopefully prevent the need to make another purchase for a few years.
If a single Ivy Bridge (like the E5-2650v2) idles in the 50-75w range (is this reasonably accurate?), what could I expect a dual socket to idle at? If I'm gonna pay a 15-20w penalty to have all of that extra power on tap when I need it, that seems worth it. If it's like another 30-50 watt, then I might start giving consideration to having a 2nd machine that isn't powered on 24/7.
