We have a five member PS6500 pool using 6248 switches.
The PS6500's are at firmware 7.1.9
The symptoms experienced are high iowait spikes for VM's at times when there are page moves going on whereas datastores loses connecitivty for a second or two. Note that the active page moves happening (I have pm mon in a window constantly monitoring) are not for the datastore(s) affected at that time. There is some correlation in the logs in SAN HQ when there are connection reconnects or volume moves noted but not 100% of the time.
So for example when the current pm plan is done everything is extremely stable. As soon as a new plan starts the issues rear their ugly head again.
We do have a case open with a great pro support engineer but it seems like my choices are to break the pool to three and two members which is not something I want to do for a number of reasons, or ask Dell to simply stop the re-balancing period as it is causing far more harm than good.
Anyone else experience the same issue and if so how did you solve it?
