Network problems with DSS

[hologic]

Hello Beng,

I was thinking in the same direction.

I've tried to set the ports to a fixed speed (1000Mbit/full) and it appears to be working.

Latency is a little bit higher on some machines but the network is stable.

It appears to be one of the two network interfaces on the server.

When connected to the second network interface the network gets unstable.

Going to do some further testing.

G'day Hologic,

Latency is a little bit higher on some machines but the network is stable.

Good to hear, is the latency just during pings? ie does it stay at <1 and then spike for a few and return?
If so I have seen that too, and not quite sure what is going on. So far it does not seem to cause any issue with the clients...

I've read through:
http://www.vmware.com/files/pdf/ESX_...erformance.pdf
and
http://www.vmware.com/files/pdf/perf...devices_wp.pdf

Which are interesting.

But this is WAY offtopic, and Thom will probably shut us down soon

Cheers Ben

It seems that the NAS part still has problems. When we start the copy with 2 concurrent robocopy actions, the system works for about 10min and then the network problems begin.

Also we are receiving errors that the specified file cannot be written to the share. On the network we are seeing ping time-outs and rising ping times.

The amount of files were a copying are big, very big. Several millions in several thousands of directory's. Sizes range from 50kb to 35Mb.

The seems that after a certain amount of files, the shares/smb disconnects.
Somebody on the forum had the same problems after approx. 65000 files.
Does anybody know what the limitations are of the NAS/SMB part for Open-E?

The ISCI part is running stable now, with the Nortel ports set on a fixed speed.
No more network disconnects/timeouts.

3 systems are now connected to the Iscsi (1 system with 2 robocopy sessions copying several millions of files and 1 ESX 3.5 system).
