Thank you, Leon.
Could you please collect the logs from the problem system and post here the link to them?

hello Michael,

i send you a PM with logs of hyperv3.
Do you received it ?

Hello Leon,
Yes, I have got the logs, thank you.
In Starwind logs I found the events about the read/write delays on HYPERV3 node.
Also in System logs there are events from Server Administrator like: Command timeout on physical disk: Physical Disk 0:0:13 Controller 0, Connector 0
Could you please double check the underlying storage there?

hello Michael,

thanks for your help, i dont have see this logs before but
i don't think this "dell server administrator" logs are some clues.
i change a lot of sata drives in this server and i think this alarm come from that.
(i change from sata 3g/s to 6g/s for test if that's correct my StarWind speed probleme, but not )

i double check logs but this alert logs does not show again since 06/11/2016.

and i have a another dual node StarWind cluster for test with ssd disk and it has the same issue.
first node write speed is slow.
So i don't think that's an hardware issue.

some news here ?

Hello Leon,
We never saw such behavior in our lab and on HCA servers as well. Every time the performance of HA device is equal on both servers.
Could you please run the performance script on both servers and compare the results? I will send you a link to download it in PM.
