[Veritas-bu] Encryption - LTO-4 or Media Server

Hi All,

We are considering NBU Media Server encryption rather then LTO-4 encryption. I know there is potentially a performance hit at the media server, but also a potential performance increase due to multiple streams being converted to a single, larger, encrypted stream being written to tape.

We are NBU 6.5.2a Solaris 9 master, another Solaris 9 media, stretched metro SAN, LTO-2 drives (moving to LTO-4), EMC CDL700 (moving to DL3D). Hardware for both master and media is SUN V440 4CPU@1062MHz 8GB RAM. Also use VCB proxy host (W2K3), and remote media servers (windows) for Puredisk.

Just wanted to see what others are doing, and if anyone has any good/bad experiences with either one.

Thanks.

--Jeff
