    Virtual Plan Advice

    Hi there guys

    Can you look at the plan I made, see what you think

    Don't really know about the last few on the list, seems overkill to have its own virtual server

    Just to add, has I didnt say this in the document, all host servers have 2x intel quad processors (can't remember what speed)

    Maybe in the future we use one of the server hosts for the admin network? (configure it with a vlan)

    Thanks

    Reading it quickly some things cam through my mind :

    * Why need w2k8 r2 datacentre or enterprise ?
    * I would split the FMSO roles between the 2 DC's (possible due to both DC are GC)
    * VM14 is not needed.. you add DHCP roles to both DC's
    * 1 VM for exchange2010 ? i dunno how many users you have but this seems a little to less
    * VM15 & VM 16 are not needed you can add those roles to both DC's as well
    * i would recommend an 3rd DC that is running on a physical server

    regards

    Because If you have standard, you have to buy a standard licence for each VM (not the host)

    Enterprise allows for 8 vms you only pay for how many processors you got on the hosts (unless you buy more licences, to be able to use more vms), so only 10 licences needed for us, will be more expensive but will allows for more headroom in the future.

    Datacentre is licenced the same way has enterprise but allows for unlimited vm (doubt we will go for this one unless it not much more the enterprise)

    How can you have two DHCPs? Through you can only have one per a doamin?

    Well at the momment we only have one server for the exchange, so im assuming it will be ok still, or do you think to have two? Maybe one for students, and one for staff, or just a backup?

    Why would you recommend doing that? I through dcs were fine all virtual? I was thinking of having the hosts not on the domain, has the dcs would all be virtual, which mean they start up after the host, so there wouldn't be any problems

    You can split the scope between the 2 servers so that they don't issue overlapping addresses.

    I too would recommend still having a 'Physical DC' alongside the virtual infrastructure and that is what I have.

    You can never be too sure!!!

    Regarding the standard or enterprise\datacentre license... I was thinking the VMware way. But i see you are going for hyperV
    Most consultants will say to have at least one DC that is not part of your virtual infratructure. If the virtual infrastructure collapses you still have a DC with an AD database up & running. It will speed up the recovery progress
    For exchange 2010 : ms recommends at least 12 GB ram if you combine a server with roles like CAS, HT,mailbox. If possible i would place 2 of them. Lets say with 8 GB mem. If troubles arrise you'll have 50% of your exchange environment still running

    Ok sorry for me being dumb here but how does the failover feature work?

    Is it just when a server goes down it move the vms over to a another server?
    If that is true does it do that when you restart a host server too?

    So if a vm image goes down, it case of manually fixing it like a normally on a normal server?


    Well it does seem we have spare ram going, so we could do two exchanges

    I would say one for students and one for staff.

    Well if you run vmware it will failover fine if one hosts goes down. (or if a VM thats is fault tolerance enabled goes down)I dunno if hyperV also does this.
    Regarding the exchange : if one vm goes down you still have 1 VM with some mailboxes up and running. You won't lose your entire exchange 2010 organization if the only one VM goes down. I would create 2 exchange databases per exchange server. 1 DB for staff and 1 DB for students...

    Definitely agree with a physical DC - as the 'PDC' with DHCP. Yu'll be glad yu did. A lot less hassle in the long run

    Ok will try to soft out where to place a physical dc, don't know where tbh. Don't really want to put it on a vm host, want them use to be a host only.

    Agreed about dns on both dcs has well has using 2 dhcp on both two with splitting the scope, and splitting the CMOS roles on them two.



    Ok have I got this right?

    A failover is where one vm host goes down?
    All the vms transfer to other vm hosts? (shared SAN)
    How about if you was to restart a vm host, would the same way happen?

    If this is the case, is it worth splitting some of the sites on the website.? Ie I could move the vle to it's own VM

    Gonna put in a share pint vm too, have can get that ŵorking and that will replace word press has our school website, even I have just got word press point there are a lot of limits, chaining things ain't easy, got to work with php coding in the theme files, which I don't know how to do

    ok updated again - how would I setup exchange to failover to the second exchange server if the first one went down?

    Or should I just setup each server like this?

    MAIL01 - Student Database
    MAIL02 - Staff Database

    I like the idea about the physical server, but at the moment I can not see a server we can use for it, I dont want to use a VM host server

    Cant use the old server 3, has this is not x64, so no good for 2008R2

    Can I just pick up on the Enterprise/DataCentre licensing.

    I am currently in the process of splitting a couple of our virtual servers up and short term, will probably require a couple of extra server licenses. Long term, may also need an extra one. Looking at prices, a standard license is about £50, enterprise about £160 and data-centre a few £ more. So basically, data-centre and enterprise = 3 standard licenses but allow multiple virtual servers under the license agreement. We are going to end up with one server host running 3 virtual servers, so the maths with enterprise and data-centre are beginning to stack up.

    I just want to confirm a few things...

    Quote Originally Posted by p-dave

    Are you saying that with a host running 3 VM's that I only need 3 standard licenses total and not a fourth to cover the host itself?

    If I go enterprise or data-centre, is it one license per physical machine or is it per processor licensing?

    If I go enterprise or data-centre, can I retro apply this to my existing host and move its license off for later reuse? Don't think I need any of the enterprise or data centre features other than just the license, but if the server could be upgraded easily, then it may be worth considering.

    If I remember correctly, all versions of Server were included on the media installation disc?

    If I go enterprise or data-centre, do I then have to buy other versions of software or can I stick with standard versions like SQL, TMG and Exchange (SQL and TMG licensed on per processor model)?

    Thanks

    We have been quoted £70 on microsoft schools agreement for each lience for the data centre. Yes it is per a processor licence.

    Yes if you have standard you need one for the hyperv host and one for each virtual server that you use.

    Data centre will allow you to use has many virtual servers has you want on the server. Enterprise I believe was only 8.

    Yes all versions of the server is included on the install disc.


    Yes you can you any version of SQL etc. The licening is only for the servers, doesnt matter about anything else


    Cant see why you couldn't move you current licening to other servers

    Couldn't you run the host on Hyper-V Server 2008 R2? There's no licence cost to potentially worry about then.
