We recently needed to expand the storage space we use for backups. For this, we use a HP NAS 2000S, which is just a DL380 G3 with a faceplate, and two MSA20 storage shelves with SATA disks.
We had 12x 250GB, and 12x 750GB drives.
There is plenty of discussion around on the web about upgrading the drives yourself, and it’s hard to get a clear picture on whether or not 2TB drives are supported. On his blog, Stephen Wagner mentions that he had used a 2TB drive successfully. This was enough for us to know, so we went out and ordered 12x 2TB Seagate Constellation ES, and 12x 1TB of the same model. We chose to use these drives because that’s what our original HP-branded ones were.
There’s also another interesting blog article about upgrading the drives here which goes into some more detail.
Ours are now all up and running perfectly without any issues, we’re still running enterprise-class drives, and we saved a heap of money.
