Question regarding Hyper-V environment planning

    質問

  • Hi,

    We are planning a Hyper-V environment for our client. The client has about 70 workstations and 10 servers. There is already test environment running on one Hyper-V host. This server's hardware specs are: HP Proliant DL380 G6, 18 GB RAM, Intel Xeon E5520 CPU and 2 TB hard disk.

    There current servers have very common roles... AD, DNS, DHCP, file, print, WSUS, Exchange (2003!), etc. Nothing that special that should be considered here.

    The client is budjeting very soon and I should recommend them something. :)

    I think I would recommend them to have two Hyper-V host server and one shared storage. What do yout think?

    Can we use the existing server (HP Prolian DL380) with one Hyper-V host and buy only one new server? Or should we buy two new servers?

    How about the storage, any recommendations? What RAID to use? What disk speed? What system (iSCSI, SAN)? What are the key differences?

    Best regards,

    Toni

  • Hi,
     
    If you want to convert all 10 servers into virtual machine, then you need to consider the performance of the Hyper-V host machine. If the existing server is powerful enough, you can still use it as a Hyper-V host machine. Then you can buy a new one. You can balance the virtual machines on two Hyper-V host machines.
     
    Storage is always a headache, if you have enough budget, SAN with fiber channel or iSCSI(10GB is better) is a good choice. Or else, you can use RAID 10 as local storage.
     
    If you want to build a Hyper-V Failover Cluster, you have to use a shared storage instead a local RAID array, such as SAN.

  • Hi Tony,

    If your client wants to have unlimited VMs, yes the client should buy 2 Datacenter License.

    Note : Standard Edition can have 2 VMs, Enterprise Edition can have 4 VMs, Datacenter can have Unlimited VMs.

  • Hi,
     
    If you don’t need a Hyper-V Failover Cluster, use RAID as local storage. SAN is not required for Hyper-V Failover Cluster, you can use some iSCSI NAS, or a computer with Microsoft iSCSI Target software installed(if it’s acceptable in your environment).
     
    By the way, in Windows Server “8”, you can use a network share.

  • Hi,
     
    General speaking, as best practice, it is recommended that you use identical servers in the same cluster, this will make configuration easier and eliminate potential compatibility problems. In Hyper-V Failover Cluster, you can use different mode of servers. However, the processors of the servers should be come from the same manufacturer, both from Intel or AMD, you can’t mix them in the same cluster.

  • Hello,

    If you are looking to build a highly available infrastructure for your client, then a two server topology with shared storage would certainly make sense.  You could use iSCSI, SAS, or Fibre.  For a small implementation SAS might be the easiest, though iSCSI also uses a very common skill set.  The topology should include the necessary networking, as well as storage for your workloads.  For disk that calculation will need to be done by understanding your applications.

  • Hi,

    Do I have to have SAN system to use Hyper-V Failover Cluster or can this be used with iSCSI as well?

    SAN system could be a bit too expensive for this sized company... So I think perhaps some 10GB iSCSI could be the right choice... Any recommendations for manufacturers / models? Any good / not so good experiences?

    Best regards,

    Toni

  • Hi,

    Thanks.

    How about the host? Does the hardware need to be identical or can use the G6 series server as one host and buy G8 series server to a second host?

    Best regards,

    Toni

  • Hi Toni,

    for Hyper-V Cluster , 2 servers should be identical in every thing like model , processor Type , number of cores . put in mind the cluster scenario you want to acheive , are you planinng to use Active/Active or Active/Passive

    Thanks,

  • Hi,

    Thanks for all these great replies!

    How about licensing on these servers? What would you recommend for licenses? Currently the customer has mixed environment with Windows Server 2008 R2 standard, Windows Server 2008 R2 datacenter and Windows Server 2003 standard.

    What would be optimum licensing solution for this (if we ignore the existing licenses)?

    Best regards,

    Toni

  • Hi,

    If the Hyper-V host machine is Windows Server 2008 R2 Datacenter Edition, then you can run unlimited virtual machines on it. The virtual machines can be any version of Windows Server system.

  • Hi,

    In this scenario when there would be two hosts... Does client have to buy two Datacenter Editions?

  • Please run MAP tool and do assess your existing physical servers. This will assess CPU, Memory, storage & Network of all your servers. Please share the output so that we can seize the server hardware and storage easily. You can download MAP tool from http://www.microsoft.com/download/en/details.aspx?id=7826

    I have downloaded, installed and ran MAP tool. What output of the map tool you would like to have shared?

  • Hi,
     
    Does client have to buy two Datacenter Editions?
    >> It depends on your planning, requirements and budget. If you want to build a Hyper-V Failover Cluster, then you need another Hyper-V host machine.
     
    What output of the map tool you would like to have shared?
    >> Didn’t get your concern.
     
    However, if you want to use Microsoft Assessment and Planning Toolkit, you can check the following guide.

    >>> As I have said earlier in this discussion, I am building failover environment. So two hosts would be needed. So: "Does client have to buy two Datacenter Editions?"

    What output of the map tool you would like to have shared?
    >> Didn’t get your concern.

    >>> As Sajeed said: "Please share the output so that we can seize the server hardware and storage easily." -> so what output would you like me to share? It generated quite a lot of files...

  • Hello,

    I would suggest datacenter edition.  You can then hold unlimited virtual machines on the hosts.
