Readynas 2100 with esxi 4.1 peak every hour
Hi!
I have noticed that i have a hugh latency on my virtual machine disks that are located on readynas 2100 over iSCSI. iSCSI is running on a separate network/switch HP gigabit. The pattern is every hour a peak occurs on all VMFS volumes (i have 4) on the readynas 2100. I have added das storage and also started my old Open-E appliance. Look at the image and you can see the difference. Before i connected das and Open-E storage i had all my vm on the 2100 and then the latency could rise to 160ms in latency. I hade a crash recently on one machine that is a fileserver. I guess i overloaded the 2100. I only use the 2100 for virtualmachines and nothing else is activated.
Nas01-04 is the Readynas 2100 and i run 17 vm´s now the other 10 vm´s is located on either DAS or the open-e and their latency is ok. Does Redaynas 2100 do some kind of indexwork every hour that could explain the pattern?

- Nothing that should be taking up too much resources. You can check the logs and see if there anything happening at those times or you can send them to to me to look at.
