vSphere 4 - Support on the Way?

[To-M]

Engineers are investigating the bond issue as this is where they think the problem is also they are looking into the maxburst issue as well. I would leave the defaults for now. They will have to get some update for V6 to solve this issue with SCST.

Todd -
Sounds good. I will wait for advice then. It seems to be running OK now and not dropping machines, but the performance is still a little less to be desired.

If you need anything else from me let me know.

Thanks again for your help.

Todd -
I have been running with the v6 beta (update1) in the balance-rr mode since we last spoke, and the virtual machines are no longer dropping in vSphere 4. The performace is still a little on the middle tier, but at lease I have the stability problems resolved. I am getting on average 50-60MB/s read and 40-50MB/s write on both the RAID10 and RAID6 LUNS within VMware.

Is there anything else you would like me to try or change? I can also upload logs from both systems if you would like. I have roughly 38 days left on the beta demo. Any word on the final release?

Thanks again,
Jason

Hey Guys,

I think I have my issues resolved as well. Our issue turned out to be the NetXen-based 10GbE NICs. They were HP NC510C cards (Single Port CX4).

Once these cards were replaced with Intel 82598EB-based cards by SuperMicro the LUN dropping has disappeared and all VMKernel logs and DSS logs look clean and clear.

I will keep you guys posted with test results once I get my balance-rr setup on the 2-port NICs.

Thanks for the update. Engineers will compare other results and look to see if there is anything else. We are working with the SMC 10GbE nics but we wont have time to get the drivers ready for this version.

Todd - Do you want me to send my logs?
