We have an R710 Server with five 2.5 SCSI drives $146GB each and three 600GB SCSI drives. We have no more slots.
We want another 2-4TB of space. This server is used for running virtual machines for testing software applications. We need decent speed but more importantly need a cost-effective solution for running the VMs.
The budget would be in the $1000 range give or take. I might be able to get $3000 but a $10,000 solution would be too much. We could consider removing the 5 146GB drives and replacing them with larger ones but that might not be the first choice.
What you're asking for is really hard to do within the given budget without sacrificing significant performance (from what you have right now in performance).
For $3k any (Dell) external storage solution is out of the question (think MD1200/1220).
On the market, 2.5" drives max out at 1TB @ 7200rpm, 900GB @ 10k rpm or 300GB @ 15k rpm.
Dell has 1TB 7200rpm 2.5" enterprise drives (for PowerEdges) for ~$440 (see here). These aren't the best choice if you want any kind of performance though.
You could look into upgrading to 900GB 10k rpm drives. These run $799 each right now on Dell's site (see here).
If you replace each of the 146's one at a time and let them rebuild you could then use the extra space to make another virtual disk. This would yield about 2800GB.
If you cannot budget 5 of these, depending on the current raid setup, you may be looking at a backup and restore of the virtual disk on the 146's.
- use 2 of the existing 146's in raid 1 for the OS and some extra space
- use 3 x 900 in raid 5 (yielding a raw 1800GB (so ~1674GB usable)
- use the 3 existing 600's in raid 5 (yielding ~1116GB usable)
