I'm switching gears for now. I know for sure that increased VM usage causes intermittent outages for us. I look at the performance graphs in vcenter at all levels and don't see anything exciting. I am mostly concerned in the storage at this point. I am looking at read/write latency from within vsphere. We have an iscsi environment and we have average read latencies for the last week as high as 30ms. This doesn't sound too bad on the surface but curious what you guys think.
