Re: [Veritas-bu] NDMP backups from Netapp using Netbackup

I assumed since someone mentioned CIFS that we were talking
about file servers. I don’t mean to disparage NetApp or Sun. I’ve
had no issues pushing 100+MB/sec from my filers with large files. However, I’m
in the untenable position of having a 20-30Kb average file size which necessitates
creative backup solutions. I’ve had success in this scenario running
multiple streams.

We’ve got one Sun device we run 16 simultaneous NFS streams on that
pushes 30MB/sec. Have you tried hitting multiple mounts with individual streams
at the same time to get better CIFS performance?
We did some testing of VMware accessing our FAS3140 via NFS and benchmarked a
guest at 340MB/sec over port-channeled 10GigE connections using jumbo frames.
And that was to 1 head in the 3140 cluster.
