This is really a pre-sales question, but I have not been able to find a sales person who can answer this question.
We're think of buying an R510 to use as a massive 7000+ user mail spool. I would like to configure the 12 internal SAS disks as 6 RAID1 volumes. (Please I am set in this decision. We cannot afford a SAN, I want to maximize write performance , minimize RAID rebuild time, and the app lends itself well to 6 individual volumes.) The online configurator will only allow me to configure a 12-disk with the H700 and "two sets of Raid 1", "Raid 1 with exactly two hard drives and RAID 5 minimum three hard drives", "RAID 5 minimum/maximum four hard drives and Raid 10 minimum four hard drives, maximum depends on backplane [??]" Is this just a limitation on the preconfigured RAID configs I can order, a licensing restriction, or a true limitation on the number of volumes that the H700 can support? I suppose I could go with one or two big RAID 5 volumes but I want to be able to get 500 or 600 iops small write performance and less than half a day RAID rebuild time. If anyone is getting those kinds of numbers from an H700 with RAID5, let us know, that would be helpful. I'm also willing to install a 2nd controller if it can be connected to the hot-swap SAS disks.
