  • Exchange Server 2007 SP1 as Guest on Virtual Server on WS 2008 Core?

    OK, now I have an HP ProLiant ML350 G5 server (2 X Intel Quadcore porcessors installed at 1.6 Ghz each only), 16 Giga RAM, 5 X 146 GB SAS drives.

    My plan: I want to install Exchange Server 2007 SP1 as Guest on a Virtual Server (Citrix XenServer v5.0, 64 bit).

    Questions:
    1. I want to install on the Virtual Server as OS Windows Server 2008 Core and on top of it Exchange Server 2007 SP1. I read somewhere, I really can't find the source, that Exchange Server 2007 SP1 cannot be installed on Windows Server 2008 Core. Is there anyone who can explain to me as to why this is not possible?
    2. I want to install the Unified Messaging role of Exchange Server 2007 SP1 as well, but I read that the Unified Messaging role of Exchange Server 2007 SP1 is NOT supported to run as Guest on a Virtual Server. Source: http://technet.microsoft.com/en-us/l...EXCHG.80).aspx
    Is there anyone who can explain to me why specifically this role is excluded and not the other roles like Mailbox Server, Edge Server, Hub Transport, CAS?

    I also would appreciate if someone can send me the link where Microsoft states that Exchange Server 2007 SP1 is not supported to run on Windows Server 2008 Core.

    I am looking forward to receiving your expert advise.
    Kind regards, switch

    You can't use Core for Exchange 2007 because you need the full GUI. You need MMC, Powershell etc. Core doesn't have that. I am not aware of any document from Microsoft that says you CANNOT use Core, but if you look at the requirements then you will not see core edition on the list.

    But if you don't believe me, why don't you try it?

    As for UM, it is not supported in a virtual machine for the simple reason that the performance sucks. UM is very very processor intensive. I have tried it, with a fast machine giving it everything that is available, and it was useless for one user. I can't even demo UM unless I use a physical machine.

      Sembee, thanks for your feedback. Makes sense that Exchange Server 2007 SP1 won't work with SW 2008 Core as you explained. Believe me, I'm not going to try it out myself; I have no time for experiments. I take your word and have complete trust in what you're saying.

      On the other hand, the issue with UM is related to performance. How about allocation 4 cores (@ 1.6 Ghz) on UM with e.g. 8 GB RAM? I currently have 16 GB RAM, but I have no problem at adding another 16 GB just to get it working. Or allocating 16 GB RAM. 16 GB RAM costs less than $ 1'000 today (2 kits with 2 modules 4 GB each). That's cheaper than buying me a separate (hardware) server.

      Please note that I will use XenServer v5.0, which has significantly less overhead than VMWare's ESX. From hearsaying, so I don't know if I'm correct here. Also, please note that all is on 64bit, which should give it a boost compared to 32 bit. But I assume you already discounted the 64 bit into your consideration, as Exchange Server is available in 64 bit only.

      What's you opinion?

      Appreciate your expert knowledge!

        Do you want to be in a supported environment or not?
        Microsoft have stated that UM is not supported in VM, whereas everything else. That should be the end of the conversation. Microsoft have tested throwing lots of power at it, and have made that decision. If you decide to go against that then you are unsupported, which means Microsoft could quite rightly turn round and say that any problems you have with the product are because it is in an unsupported environment.

        UM isn't about RAM. It is all about raw processing power because of the voice capabilities.

        Simon.

            Sembee's reply was factual, clear and (more importantly) correct. I sense no improper "tone" in his post and I don't see any reason for a response in this vein.

              I suggest you go to Experts Exchange and check out the "hall of fame" before you start rejecting this particular piece of advice.

              As stated, there is absolutely nothing offensive in Sembee's post -- he is giving you, for free, support that he could charge a lot of money for.

                I'm with Sembee. Additionally, you can't really carve up 5 disks into a Best Practices recommended configuration even on a physical box. UM and MBX shouldn't go on virtualized hardware for just the reason Simon mentioned - it's not supported, and it just plain sucks from a performance standpoint. UM requires true access to processors, and MBX needs hardcore access to the drives. Putting something in the middle of that is just asking for trouble.
