Well, with a shared NIC. accessing a share on a VM will basically be funneling traffic through the NIC twice. You are taking a 50% network performance hit right there. It is a limitation of the network architecture you have.

Hi Cliff,<br />
<br />
Ok the server does have 4 nic's in total so could we do something there, i dont understand the virtual switch in hyperv so may not explain myself correctly.<br />
<br />
Also the nic that is assigned to the virtual switch says it has a connection speed of 10Gig but is only a 1gig card

Hi,<br />
<br />
We have a HP DL 360P G8 with 96 Gig ram, the server runs 2012 server with the hyperv role installed, there are 6 vm's installed these are all located on a Netgear Ready Nas 3200 with a single iscsi lun connected to the server.<br />
<br />
HyperV is setup with a single virtual switch connected to a single nic on the server, we have issues with read speed when accessing data on shares that are on the vm's but not when accessing shares that are on the iscsi but shared off the physical host server.<br />
<br />
Thanks,<br />
Craig

Microsoft Virtual Server was a virtualization solution that facilitated the creation of virtual machines on the Windows XP, Windows Vista and Windows Server 2003 operating systems. Virtual machines are created and managed through a web-based interface that relies on Internet Information Services (IIS) or through a Windows client application tool called VMRCplus. Features included Linux guest operating system support, Virtual Disk Precompactor, symmetric multiprocessing (SMP), x64 host operating system support, the ability to mount virtual hard drives on the host machine and additional operating systems support, including Windows Vista, and a volume shadow copy writer.

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.

Windows Server 2012 is the server version of Windows 8 and the successor to Windows Server 2008 R2. Windows Server 2012 is the first version of Windows Server to have no support for Itanium-based computers since Windows NT 4.0. Windows Server 2012, now in its second release (Windows Server 2012 Release 2) includes Foundation, Essentials, Standard and Datacenter, and does not support IA-32 or IA-64 processors.
