Re: [Networker] NetWare throughput
2007-12-04 12:14:32
Somewhat better here, though we've never been impressed with the speed
of the NetWare client. Our biggest volume (~770GB, 1.2 million files)
backs up to disk in about 13 hours (1GB/min, 16.67MB/s).
This is pretty much what we get from all of our NetWare volumes. The
only exception is the volume that hosts our workstation images (maybe a
dozen 2GB files). Here we see ~25MB/s.
We used to tweak the TCP/IP stack a tad (to increase buffers, receive
windows, etc.) but recent kernels do a good job of autotuning and this
is generally frowned upon.
No magic bullet here, unfortunately...

Hi
I'd be interested in the asnwer to this too.
We basically have the same issue - a 380GB volume which takes about 15-16 hours
to backup.
My hunch is that it's the number of files (1.2 million) or the poor Netware
client (7.2).
I've also setup load balancing on 2 GBe NICs but it doesn't really help. The
bottleneck seems to be trawling through the file system.
Be interesting if anyone is getting much better throughput than this on Netware
with similar sized volumes/number of files.
Cheeers... allan.

Fellow admins,
Just need to find out if there is something like 'bigasm' on Windows and Unix servers which I use on my NetWare clients to test backup throughput. Somehow to backup 500 GB of data, it is taking almost 24 hours to complete. This NetWare server is a Dell PE 2850 with quad processor and 8 GB of RAM and connected to a GB network.
My environment is:
Networker server v7.3.3 on Red Hat Linux ES 4 backing up to disk devices.
NetWare client/server v7.2 on NetWare v6.5 support pack 6.
Any help or advise is greatly appreciated.
regards,
