TSM 5.1.6.5 on 2K server. Current library is Overland Neo 4100 LTO-2.
We need more capacity in our backups, and I'm looking at faster restore altenatives. Has anyone here used the Overland Reo 400x series, or anything similar? It's basically SATA drives enclosed and RAID'd. And you can configure it into LV's that emulate LTO-2 tapes.
Does any TSM'er use disk based backup? Right now the cost seems to be twice as much as LTO-2 based. I can get a 12TB LTO-2 library for about 35K (Overland NEo 4100), yet the same capacity with disk (Reo 4000) is about 70K. I can also buy a DAS RAID system with 4TB capacity for about 10K (Excel Meridian). What is so special about a D2D disk backup system that makes it twice as expensive as the DAS and tape backup?
But I'd prefer not to attach a DAS to the TSM server, because I definately want the virtual-LTO-2 functionaility, which I *think* is part of the Reo 4000 device, right? I mean, TSM doesn't do that does it? That must be a functionality of the D2D device, right?
Thanks,
Alex
