Throughput Issues

Blussenheide · Wed Sep 03, 2014 3:19 pm

All-

We have a issue with throughput via ISCSI configuration.
Currently the throughput is very very low, approx. 20M/s throughput when migrating a powered down vmware machine.

We have previously clocked the throughput at over 120M/s

We've reviewed our configuration, and everything appears to be match per spec. Has anyone seen this before.

Thanks in advanced for any help.

Unfortunately you provide not that much of a details about your config both hardware (hyper-converged or StarWind runs on the different set of machines? HA or non-HA? If HA 2-way or 3-way replica? 1 GbE or 10 GbE uplinks? Backbone? How many channels?) and software (FLAT or LSFS? Amount of cache allocated? Volume full?) which makes troubleshooting a bit complicated... Can you start with answering these questions from above and also run a fast & dirty test on x-put spawning something like ATTO Disk Benchmark inside any of your VMs. Also StarWind log should help a bit (just don't copypasta it to the message, attach or send to support e-mail acc). Thanks!
