3Par 8200 displaying latency issues when Sharepoint 2013 crawl is happening

[Largechicken8]

Hello,

Over the last few weeks we have been experience latency across our 4 controller 3par 8200. When a Sharepoint 2013 full crawl happens over the weekend it cases issues with other running virtuals such as Orcale back ups etc. This has not always been the case. No infrasturcture changes have happened. We have had HPE update the SAN OS over the last few months but can't point the blame at this. Currently running 3.2.2.612 (MU4)+P51,P56,P59,P74,P84,P92,P95

Any ideas? Thanks in advance.

What Type of Disk?

Are u using Dedup, Compression or AO?

Is it replicated (Sync, Async)?

You can limit the Sharepoint IOPS by setting a QoS.

(Will not fix the root caus, but my help.)
