Hi,

We have a dell equallogic used as ESX storage for three esx hosts.

the event log says "

active control module cache in now in write through array performance is degraded" 

This has resulted in a sluggish and very slow performance .

I have unticked both options in Members --> member name --> controllers which reads as :

use write-through mode if only one controller is functional 

use write-through mode if battery charge is below tolerance

still performance is slow and I can not find out how I can find out what mode the array is running in .

it is dell eqaullogic ps4000  model 70-0120 , chassis 1603 with control module model being 70-0120(type8)

please help if you can and all posts are highly appreciated
