Exchange running on hyper-v with two vhds running extremely slow RRS feed

  • Question

  • Hi All,

     

    I have two separate installations with this same problem - It seems that when I create a virtual Exchange Server installation with two separate (VHD) drives attached the virtual machine slows down to a crawl, takes about 10 minutes to boot, and another 10 minutes before it enables the network card and begins serving clients.

    In both cases I am using Hyper-V R2 on Dell servers. RAM and CPU is not a limitation. I have tried with a shared NIC, a dedicated NIC and a team NIC. In both cases I am using a NetApp SAN on the back end with both VHDs on the same LUN. The NetApp gets a performance/drive usage boost when you create an aggregate with all drives and biuld your LUNs on that aggregate.

    The Guest OS/ Exchange combo is 2008 with all patches and Exchange 2007 with all SPs. The other install is using server 2008 R2 with Exchange 2010.

    Anyone seen this before?

    Shaun
