NIC in StoreVirtual VSA on Hyper-V is not running at wire-speed when attached to a 10 Gb Windows 201

Hi,

We use two HP StoreVirtual VSA 12.5 nodes installed at Windows Server 2012 R2 hosts with 10 Gb network adapters. But communication with VSA is not running at speed 10 Gb.

I think that the problem is in drivers inside VSA virtual server based on Linux. Virtual servers with Windows Server 2012 R2 operating system with enabled SR-IOV option are running at 10 Gb speed without any problems.

I have found notice in document HP LeftHand OS Version 12.0 Release Notes at chapter Workarounds at page 19 http://h20564.www2.hpe.com/hpsc/doc/public/display?docId=c04514442 ) :

NIC in StoreVirtual VSA on Hyper-V is not running at wire-speed when attached to a 10 Gb Windows 2012 Hyper-V vSwitch

When a Hyper-V VSA NIC is connected to a 10 Gb Windows 2012 Hyper-V Switch, it does not run at the full potential of the physical NIC. Currently, there is no workaround. The issue is being investigated by Microsoft.

The problem is not solved in version 12.5 that we use. Is the problem solved in version 12.6 ?
