Okay, I've hit a wall. Short story setup: We have 3 VMware ESXi hosts. They connect to our network via a HP Procurve 2510G-48 at the top of the rack. Each has a pair of Gigabit ethernet connection connections going to that switch, setup as a trunk. We have been dealing with some minor latency issues, mostly the occasional timeout on our Mail server's web interface. My current thought is that the 2510G-48 might not be able to handle the load... So I've moved the three servers' uplinks to our 5308xl as a test to see if these timeouts disappear. The move went smoothly, except on the 3rd host: If I have both Gigabit connections enabled on the 5308xl, I cannot ping Host 3. As soon as I disable one of the two ports on the 5308xl (either one), it pings. Switch Configuration:Port H1-H2 Trnk-1 TRUNKPort H3-H4 Trnk-2 TRUNKPort H5-H6 Trnk-3 TRUNKEach has Spanning Tree Priority 4. The vSwitch on all the hosts are setup the same way:Load Balancing: Route based on IP hashNetwork Failure detection: Link Status onlyNotify Switches: YesFailback: Yes If I can't figure this out, I'll be contacting my vendor for support. Thanks for any ideas.
