Hello everyone,
This is not directly related to CentOS but still: we are trying to set up some storage servers to run under Linux - most likely CentOS. The storage volume would be in the range specified: 8-15 TB. Any recommendations as far as hardware?
I would recommend dont-homebrew. Get a vendor to build you a 3/4U box, get a couple of quad core cpu's in, and enough ram to do you in-use buffers. Also dont go over 1 TiB in storage per spindle if you want to get even relatively reasonable performance ( even when in use as a filer box ).
Not long back, I had the chance to do some performance metrics on a dual Areca-16xx hosted 24x1TiB disk setup - and we tested it for various loads, running CentOS-5.4/x86_64 and it consistently outperformed the sun thumper box's, coming in about 1/4th the price.
The other thing to keep in mind is to estimate and prove the cpu processing capability and network capability you are going to need out of this machine and dont skim on that. Dont just get overly focused on just the hba and disk metrics.

KB, thanks. When you say "dont go over 1 TiB in storage per spindle" what are you referring to as spindle?
Generally 'spindle' == 'physical disk drive'.
