Advice on new Server Hardware
Posted on 2012-03-27
I have a hardware dilemma so I am turning to the sharpest group of tech people I know.
I am purchasing a new 2U server. This server will be running VMWare 5.0 esx for the OS, and the main VM running under that will be a windows server 2008 with a SQL database for Prolaw software. (Other VMs may be added later.) We will be running 4 constellation 3TB drives in a raid 10 configuration. 128 GB RAM and dual processors. I am leaning towards Dell brand servers.
I am satisfied with most of my specification decisions but I would like some input on the items below. I am looking at 2 processor / ram configurations and I am very torn between them. Some of this indecision is because I haven't kept up on the higher end technology so I am not sure which would suit our system best. Here we go.
Processor = AMD Opteron 4284, 3.0Ghz, 8 core, 8MB L2 / 8MB L3 cache
RAM = (8x16) 1066Mhz, Quad Ranked, RDIMMs (Low Volt), AECC (?)
Processor = Intel Xeon E5-2630 2.3Ghz, 15MB cache, 7.2 GT/s QPI, Turbo, 6Core, 95W
Ram = (8x16) 1600Mhz, Dual Rank, x4, RDIMMs (Std Volt)
I like the extra bang for the buck that I get from AMD, and VMWare says that both processors run equally well with their OS.
I like the extra cores & Mhz with the AMD, I like the 1600 Mhz RAM with the Intel.
I don't know what the Dual and Quad ranking means to the RAM performance.
I don't know the GT/s rating for the AMD.
I don't really care about the power usage (Low Volt vs. Std Volt) unless it is a factor in performance or longevity.
The AMD says that is supports 1600 Mhz RAM, I'm assuming that they are not in the AMD quote because of motherboard / other limitations (I have that question submitted to Dell and I am awaiting an answer).
My Question is:
Which or these configurations would you recommend given the information above, and why.
Also, if anybody can briefly explain what Dual and Quad ranking means to the system (performance? Longevity? stability?) that would be very helpful.
Thanks in advance!
