Dell EqualLogic 6100 with high average latency

I have an array with very high latency mostly on the reads.  It's affecting performance on our VMs.

Its 8TB, has solid state drives, iSCSI and has 4, 2TB volumes attached as datastores to vCenter 6.7.  I'm not sure where to begin.  This is not normal and has recently been discovered.  I've added some screen shots.

Any help would be appreciated.
