Alletra 6030 iSCSI performance during cloning operations

[jbeach44]

Hello!

We are seeing an odd issue with our VMware environment when performinig high I/O cloninig operations where the ESXi hosts will lose access to the datastores. It lasts for around 10-15 seconds and some VM's will become unresponsive. 

ESXi hosts are Dell Poweredge R740's with 4 qlogic 41000 series NICs connected over 25gb fiber.  ESXi version VMware ESXi, 7.0.3

Alletra is also running NICs over 25gb fiber. OS is on 6.1.2.300-1042680-opt. 

Performance is great throughout the day, but whenever we perform cloning operations from within VMware, we see issues. 

Any thoughts, ideas or same issues being observed?
