[QUOTE=bgbeuning;417562]Score! I would like to hear your experiences with it. I do not see Keyboard, Video, Mouse (KVM)
connections, just Ethernet connections.

I have the server. It's a full generation older than the C6100, using Xeon 5420 and DDR2. On the bright side, the 8 slots of DDR2 are *not* tied to one processor, so I have 8 full cores sharing each node's memory. I think that's better for NFS matrices than NUMA-style.

Each node has a VGA port, 2 USB, 2 GigE network, and 3 hotswap SATA drive bays. Ubuntu 14.04 installed off a USB stick without issue- no drivers nor special treatment needed.

4 nodes, each node 2x4-core@2.5ghz + hyperthreading. A variety of scrounged memory in it, currently populated 12/5/4/4GB for the 4 nodes (lots of 512MB ECC sticks!). 6 Dell 250GB server-grade disks included, as well as all 12 3.5" drive trays.

With 16 threads of sr2sieve, 16 of NFS, 21 ECM, my kill-a-watt says 660 watts. I will not need a home heater this week. I need to get a network switch and more cabling before I tinker with LinuxPMI and try to run a single NFS job over the entire machine.

You should PM me your details. If memory serves me correctly, I have a TON of older DDR2 memory modules (ECC). They were pulled out of HP Proliants whenever I had to update the memory and was unable to use the originals. In some cases these are brand new, never been used. It was sometimes cheaper to order with the base memory and then add-on later, rather than do a custom order.

In fact, let me go check right now...

Okay, I have:
74 x 1GB PC2-5300 ECC modules (official HP spares, #416471-001)

I have a feeling I have more somewhere, but these are just the ones I have in my "junk memory drawer". Don't we all have one of those?

So, let's face it, 1 GB sticks don't do much good for me when I need servers with 192-256 GB (and everything I have now use DDR3/DDR4), and it's easy to look back and see how I wound up with so many. Plus, when we send servers off to the great recycling plant in the sky, I feel bad sending their memory to be shredded, so I hoard them.

I'd *love* to send them off to someone who could use them. Let me know.

Speaking of memory, I have some bog standard non-ECC memory. 2*1GB of DDR (possibly 1 stick faulty, could be the motherboard though, not sure), and 2*1 GB and 2*2GB DDR2. If anyone wants these I can post them, but otherwise I'll just throw them away.

256GB DDR4
Dual NVIDIA Quadro K6000 12GB

Seems like most of the $14K is in the K6000's... probably get a cheaper setup by forgoing the Xeons and 256GB (unless that was needed for something else) :smile: Of course a good dual Xeon with that much memory is VERY nice, I have to admit.

I suppose I don't really need to RAM disk my entire computer :P

Most likely not...

But thanks for demonstrating that distraction is worth money to some, and that you should be ignored....

Edit: Sorry, that might come across as negative...

Umm.....I thought it was a humorous remark. :huh:

I'm not worried, the Australian sense of humour is often misinterpreted :)

Madpoo turned out to have *much* more than dozens of 1GB sticks. He mailed me a complete set of 32 sticks of 4GB DDR2 ECC, filling the server with 4 nodes at 32GB each. The memory is now installed, and will be used to run large-bound ECM curves on M1277 on a thread or two while the rest of the nodes run NFS tasks.

Thanks, Aaron! If M1277 falls to my ECM, you deserve credit for making it possible.
