Upgrade VMware ESXI from 5.5 to 6.5 now seeing latency issues

Can I just start of by saying I only have a basic understanding of netapp so please bare with me, unfortunately our netapp admins has been signed off work for a few weeks sick.....

 

 

We have ESXI hosts 2 for managment (mgt) and 6 for development (dev). All ProLiant BL460c Gen8 Intel Xeon CPU E5-2670 0 @ 2.60GHz x 2 262gb ram

 

Both Dev and Mgt connect to the same Netapp  We upgraded our hosts from 5.5 to 6.5 and since then we've been having latency issues with the dev cluster which eventually brings everything to a halt.

 

We have 2 netapp FAS2240-4

Type: HA Pair

Version 8.2.3p6 7-mode

 

 

netapp1

In aggregate i see 1aggregate

hybrid0

RAID Type:
mixed_raid_type, hybrid

 

 

netapp2 has 2 agrregates

aggr0

sata0

RAID Type:
RAID-DP

 

The 2 ESXI mgt hosts connect only use datastores from volumes on netapp2

 

The 6 ESXI dev hosts connect to both netapp1 and netapp2

 

We are using Emulex Corporation 2 x HP FlexFabric 10Gb 2-port 554FLB Adapters for iscsi on each host.

 

Sometimes we are seeing latency for some vm's up to .5 seconds. Every now and then a host will fail and the vm's will start to be moved around which causes more heavy disk usage and one by one the other hosts fail.

 

I see this in the vmkernel logs:

It only happens to the dev cluster which is uses the ssd hybrid volumes.

 

We reverted back to 5.5 once before and everything was ok. We then updated all device firmware then upgraded to 6.5 and installed the drivers according to vmware compatibility lists.
