I keep having a recurring issue that I thought I might get some help from here.
I have A vcenter 6.0 cluster with 3 hosts and approximately 180 VMs. We are in a VDI environment. Horizon View is version 6.1. We use a Dell m1000e chassis with m620 blades on the newest firmware accross the board. Storage is a Nimble CS420-X8 on version 2.2.8. I have Veeam backups to a seperate san and vcloud air as DR (but that is shut off right now, except for a couple of replicaitons).
Every few hours (not the same time of the day nor the same ammount of times a day) we get a major cpu utilization spike on our Nimble as well as our Hosts. This causes the above error: alarm.vmdisklatencyalarm accross multiple guests, sometimes as few as 1 or 2 but usually it's about 60-80.
I have tried turning replication off, backups off, checked against symantec endpoint protectoin, updated firmware, updated software, added the nimble connection manager - everything i can think of and I can't crack it.
Has anyone seen anything like this or have any insight?
I can add details as needed.
