I have a cluster of servers that are all running either with
BCM5716C NetXtreme II cards or
BCM5709C NetXtreme II cards. All servers have their cards teamed by the
BACS3 software as:
- Smart Load Balancing and Failover
- No standby members
- No live link
- No VLAN
All servers then connect to a pair of Dell 6224 switches. The problem I've been observing is that if one of these switches is off (or on but stuck in a diagnostic loop) then the servers loose all connectivity to anything. I was under the impression that with the above configuration they would just drop their speed and continue with the remaining switch until the one with issues is restored.
Why does all connectivity stop and how do I fix it? All servers are Windows 2008 R2 Standard or Datacenter. Some are used for a Hyper-V cluster.
