[Veritas-bu] NDMP performance tuning (NetApp)
2009-03-01 16:54:42
We've been struggling to tune up remote NDMP backups to windows media
server with LTO-4 and disk storage units attached across 1Gb network.
So far we've been getting around 25-30MB/s (40 at the very best with 2
streams to 2
tape drives) with 16 buffers x 64k each (or 63k each).
- I wonder if anyone has experienced better performance and what
parameters have been used.
- Is there anything else we should try / tune on either NetApp or
NetBackup side (so far we've been playing with Netbackup buffer sizes
only).
- What can we expect if we are to connect LTO-4 fibre drives
directly to NetApp? Is it worth the effort in terms of significant
performance improvement?
Regards
Glen
