I have a 3 node cluster and I am experiencing some strange network issues.
I have 4 10G adaptors in each node. 2 teamed for normal network traffic using LACP and 2 for ISCSI using MPIO.
The cluster throws a ton of errors out if I select "do not allow cluster network communication on this network" on the ISCSI network. I enabled it a while back, because the guests were failing over every 5 minutes.
I would think that with 2 10G NIC's there would be enough throughput for the heartbeat. I am thinking that is what causes this.
Any ideas?
Thank you
