Summary: We have reported an odd issue to Compellent about drop offs in performance on our SAN. They've come back to us saying that they wish to replace all 4 Dual port 10GigE cards in both controllers as a result of the issue we are seeing.While the issue at hand isn't causing a lot of problems it could do in the coming hours. Compellent have dispatched an engineer with all new cards for both controllers. The SAN in this instance provides the storage for all of the Qmail services that we currently operate. The connections from the san to the mailstore and other services are working ok. i.e. all 8 logical paths to the storage network are working but we are seeing a high error rate on the ports in the controllers which could cause performance issues.
At approx 17:00 today we'll be replacing all the cards in the SAN while the it is online. This can be done because it's built in a resilient fashion. We'll post an update in a few hours once we have firm timelines from Compellent.
