Try some other utility to measure network throughput...perhaps even an FTP
between the servers. See what the max speed is, then at least that can tell
you if its the network.

If the network isn't the problem, how is the file list / policy setup ? is
it multiple streams from a client ? if only 1 stream can you add more
concurrency by giving multiple drives rather than all drives ( I dont know
netware, so I'm applying windows/unix terms )..

On solaris, with DLT7k you might be able to up buffers to 128k, but this
isn't likely to make much difference to the sort of level you want.

Subject: [Veritas-bu] Extremely slow thruput from my Netware 5.1 SP6
Clients


All,

We are running NBU Datacenter 4.5_FP6 on a Solaris 8 master DLT7000
drives. All NIC's are mandatory AUTO - AUTO campus wide.

Historically, we are seeing less than 100kbps thruput from at least 2
of the Netware servers we backup. They claim no NIC problems and no
other network speed problems, which led me to concentrate on the
netbackup config.

Buffer size = 64 on the netware server

NET_BUFFER_SZ = 65536 on master / media servers

>From the technotes I read, this should be ok..  and having OTM enabled
shouldn't slow things down THIS much right ?

Any ideas would be appreciated, we are probably going to open a case
with Veritas soon as well.  Even if we could increase this to 400kbps or
500kbps that would be fantastic at this point.

Thanks,

Paul
