  • Exchange 2007 consolidation

    Hi,


    Our current scenario is as follows

    Total 12 Exchange 2003 with SP2 which spreaded across globe, now we are plannning to migrate to exchange 2007 and removing all server from remote location and installing only one server at head office.

    My queries:

    on which factor its recommended to install exchange server on remote location..

    e.g
    1) if users on a remote site if users/mailboxes are more then hundered then its recommended that you haev to install exchange on remote location

    2) if your network bandwidth is less then 1MB and users are 75 then its recommended tht you have to install exchange server.

    _________

    My Details.
    _________
    Site Mailbox Link Dataflow
    site 1 1000 2 Mb Message + Application
    site 2 300 2 Mb Message + Application
    site 3 250 2 Mb Message + Application
    site 4 75 1 Mb Message + Application
    site 5 75 512KB Message + Application
    site 6 60 512KB Message + Application
    site 7 80 512KB Message + Application
    site 8 50 512KB Message + Application
    site 9 30 512KB Message + Application
    site 10 45 512KB Message + Application
    site 11 20 512KB Message + Application

    Please ask me questions/revert, if any further details require

      Re: Exchange 2007 consolidation

      Reading your question brings up more questions than answers.
      For short, it all depends..

      How many users are in the remote sites?

      What kind of exchange users are these?
      Low, medium or heavy exchange users?

      How are the WAN links?
      Are they stable, dependable?

      How is your Active Directory designed?
      Domain Controllers, Global Catalogue's and DNS servers.

      What about redundantie?

      What about Migration?

      Which Client is ussed?
      How do users access there mail?

        Re: Exchange 2007 consolidation

        HI,

        thanks for your reply.....

        How many users are in the remote sites?
        well average 150 users seating in the remote site

        What kind of exchange users are these?
        Low, medium or heavy exchange users?
        Low= 70 usesr (their daily trasaction per day is around approx 2.5MB per user)
        Medium= 25(their daily trasaction per day is around approx 3MB per user)
        heavy = 15 (their daily trasaction per day is around approx 8MB per user)
        very heavy = 20 (their daily trasaction per day is around approx 10MB per user)


        How are the WAN links?
        Are they stable, dependable?
        We have 2 MB wan link between all locations low critical site have 512KB wan link yes all are realiable (goes down once in a month for around an hour or less then an hour)

        How is your Active Directory designed?
        Domain Controllers, Global Catalogue's and DNS servers.
        all location have their own DC+GC+DNS in single forest.


        What about redundantie?

        for WAN link we have redunfancy and for existing AD & exchange we dont have.

        What about Migration?
        Since company is spliting so we will create new forest for new subsidary and 30% of willl migrate to new forest/domain(ADMT)


        Which Client is ussed?
        All are Outlook 2003..

        How do users access there mail?
        we planning (need suggestion) to put centralized messaging system..


        all location users mailbox will host on exchange 2007 and they will accees it over wan using outlook 2003 client..

        average users volume for location..
        approxmately 100 users will be in remote office,...

                I was thinking that in team someone have face/done implementation for this kind of case/scenario would like to share the experience.

                once again many thanks.

                  I think the general point is there are too many factors to say "if X then deploy, otherwise, dont"
                  A lot will depend on your infrastructure and exact requirements, which we do not fully understand. Also, given you are going to be setting up a live environment based on our recommendations, there is a certain amount of "duck and cover" to make sure we dont get held liable if (when) things go wrong.

                  You have two options:
                  1) Get a consultant to spend time analysing your exact requirements and give you a best solution
                  2) Get materials to help you do it yourself

                  1) is more expensive but quicker
                  2) is cheaper but slower, but gives you the knowledge to do it again

                    Muneer,
                    Hey! I'll help you out in this. Let's complete it by Friday. I've attached a file. Please fille the same and pass it on. Rename hte file with ".xls" extension.

                    I also would like to know the expected growth in terms of remote/local mailboxes. This would help in designing right infrastructure for you. If you don't have idea, please get in touch with your management and let me know. I'll try to provide a solution based on that.

                        Re: Exchange 2007 consolidation

                        Muneer,
                        As per the data that you have provided, here are my suggestions

                        1. Total user count is 800 ( 75V.Hv. + 130Hv. + 595Av.)
                        2. Expected growth is almost double in next 3 to 5 years span of time. (i.e. 1500 - 1600 mailboxes)

                        based on the hardware availability, deploy as follows:

                        Solution 1:

                        1 - Mailbox Role (4 Gb RAM)
                        1 - HT/CAS (2 GB RAM)
                        1 - SCR (This provides DR sollution incase if you are planning to keep one server in a different site that has very good network bandwidth continuous replication) (2GB RAM - if possible add some more RAM)

                        Solution 2:
                        1 - Mailbox Role
                        1 - HT (You can have CAS role installed on this server if the situation araises if future)
                        1 - CAS


                        Storage layout:
                        3 SGs (One Store per each SG)

                        If possible, Provide RAID 10 for Logs and RAID 5 for DBs. Considering your scenarion, this would give good results.

                        If there are too many 'Very Heavy' profile users are in Remote site, either ask your management to go for better bandwidth or have a Mailbox/HT/CAS Server on remote site(s).



                        I welcome for expert's feedback on the same if time permits.



                        Note: V.Hv - Very Heavy, Hv- Heavy, Av -Average


                        All the best!!!
