I need to buy a server with 50TB usable disk for a production environment. A high speed disk subsystem is critical. And the project may scale up over time.
It doesn't need to be a fail-over cluster, just a single server. I'm looking at used equipment most likely.
I was thinking one with 4 CPU sockets would let me start with 2 CPUs and then expand to 4 later on. Lots of RAM capacity would also be great.
My first thought was to get a Dell R920 and throw a bunch of disks in it.
24 disk slots!
But then I looked at what size drives are available for those slots: 2.5 inch. I only see 2TB drives max.
Greg, for storage servers, we use some fairly plain Supermicro SC846 boxes with 24 x 3.5" slots. They were bought 2nd hand, I think we have 12 or 14, with some being used for spare parts. (power supplies), 8 currently in production. They were cheap, maybe 400-500chf a piece. They have server boards, with ipmi board etc., but not overly beefy. One quad-core CPU, 8Gb RAM. They're mainly used for serving disk to xen guests over iscsi. You might look for something like that and then upgrade with faster SATA, if needed. We have been experimenting with adding a large SSD cache (pcix) to each box, but I don't have any numbers yet. Otherwise, in the 2nd hand area, EMC and Fujitsu both do some very nice storage arrays. IBM and HP too for that matter. Careful you get one with SATA, not fibre-channel disks. SATA is easier/cheaper to replace.
