OTV and MS SQL

Hi all,

We lost some SAN disk, which meant we had to fail over to our DR site. Our web servers was brought up, and now they were communicating over OTV with the SQL server cluster (which was not affected). The response was horrible, and with wireshark I could see some retransmission etc, but not excessive. So we decided to also fail over SQL servers to the DR site, and all worked good. Also, our VMWare VCenter clients has absolute horrible response when it was talking to the VCenter DB, which is MSSQL, at the DR site. There is ample bandwidth (500Mbps) of which abour 125Mbps was used, and voice, which also runs on the line is fine. The rest of the virtual machines was fine.

I  know NLB has issues with OTV, but have anyone experienced similiar problems with SQL?

Thanks!

Jacques
