I'm currently doing some NDMP testing.
=20
Netbackup 5.0MP4 master server, on Sun V240/Solaris 8
NetApp gf940 filer, SAN attached to Hitachi storage.
Adic Scalar 24 library with two IBM LTO2 SCSI drives and onboard FC
bridge.
=20
all devices are attached via a Brocade SW24k.
=20
"Virtual Private SAN" utility on the Library FC brdige was used
configured to advertise the robotic controller and one drive to the
master server, and the other drive to the filer.
=20
Brocade has once zone for filer and drive, and second zone the master
server, library and 2nd drive.
=20
NDMP backups have been running at 14,000, 16,000, 18,000 kbps........not
in the 30,000+ neighbourhood I was expecting.
=20
Seems buffers and such on the master server would have *zero* effect on
NDMP data rates.....filer options for NDMP are basically just "on" and
"off".
=20
is there any IP "heartbeat" between filer and master that coul/would
affect data throughput?
