I've got a Dell PowerEdge R420 I'm using for backups (both disc to disc and to LTO tape). In addition to local disk (around 2TB) and an old EMC connected SAN with several LUNs, I'm looking to augment with some sort of el-cheapo DAS. Lurking in this forum I see the Lenovo SA120 might help me reach my goals, and I'd like the group here to check my ideas to make sure they are sound.
Initially I have access to a bunch of 10K 300GB SAS drives due to workstation upgrades to SSDs. These are just lying around, so I'd like to use those in this enclosure for JBOD. My R420 has a dual port LSI SAS 3801X card in it which the tape drive is connected to leaving me with an open port that could connect to external storage. I'm not concerned with hardware based RAID, though I could do RAID 1 or 10 with this unit. I'm probably not going to do RAID though, and I think single connection with a single PSU SA120 is fine for my requirements. I'll be mostly housing transitory data that will sit there then get streamed out to tape on a different interval.
At some point I'd like to be able to up the size of these drives considerably though, moving from my "free" drives to something like WD Reds in the 4+ TB range.
Does purchasing and loading up an SA120 seem to fit with my above logic? I have minimal budget, it seems like a pretty reasonable way to get 12 X 300 gig additional drives attached to my backup server.
Thanks!
