>From 600 MB/Sec per tape drive to 6 MB/Sec per tape drive. How's that
for a performance hit?? :-)

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 at 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
