Esxi 5.5 on HP DL380 servers and local SSD datastore. Veeam backup and Win 2008/12 hosts
Running fine for a long time, all of a sudden its ground to a slow pace with lots of disk write latency errors.
Nothing has changed.
Veeam one doesn't show any one particular VM - just lots of VM's
Have updated the hpsa driver and the 440 controller firmware.
Looking for any ideas on what it could be?
I'm currently checking for snapshots and none exist.
Hardware all reporting as ok. Have power cycled everything with no difference.
