  • New Exchange 2007 Server (software and hardware)

    hi guys,

    From you past experience, what hardware will I need for a server that would hold Exchange 2007 with ~150 mailboxes (maximum mailbox size would be 400 MB).

    Also I'm not sure about the licensing part...

    I'm asking this as this is my first task in creating something, and not just administering it.

    Thanks !

    You can't just say "exchange with 150 mailboxes"

    do you have a need for redundancy? What about tiered storage?
    are your users spread across multiple sites?
    how many users do you expect the environment to grow by?



    you need to have way more information than just "150 users"

      Thanks for the quick reply.

      Redundancy (if you refer to a cluster) is not needed.
      Most users are located centrally (only ~5% access via VPN).
      Future groath should be no more than 250 mailboxes.

      Feel free to ask anything cause, as I said, I lack the experience in doing this.

        run on 250GB of space required just for data stores (250 users, 1GB each. I know you said 400Mb, but I like to add fat.)

        no less than 16GB RAM, 2 quad core CPUs.

        Alot of people beleive in splitting OS, Logs and Database, so you need at least 3 RAID disk groups. (minimum of 6 disks then)

        I'd be more inclined to go with:
        RAID1 ; RAID5 ; RAID5


        depending on whether you go for a multi-server environment, you need to decide which roles go on where.
        Let's assume a single server: you need Client Access (CAS), Mailbox (MBX) and Hub/Transport (HT)

        In terms of licensing, you need an OS licence, you need an Exchange licence, and you need a Client Access Licence, for each user.

          Why are you wanting an obsolete product (Exchange 2007) when a far superior one (Exchange 2010) is available?
          You gain:
          DAGs for easy redundancy later
          Much better OWA
          Granular security
          Archive Mailboxes...

          Also I suggest you review your mailbox sizes -- 400Mb is pretty small.

            I'm going for 2007 cause I have no experience with Exchange 2010.

              so basically an HP ProLiant DL360 G7 but with 8*250 would be enough...(if it's considered I'm broking some rules by posting a brand here please let me know so that I can remove it).
              RAID 1 for OS and RAID 5 for logs and DB ?

                potentially
                although remember to take disk speeds into consideration.

                I would also probably echo ossian -Ex10 is far superior.. and if you're used to admining Ex07, wouldn't be massively different

                  Re: New Exchange 2007 Server (software and hardware)

                  So a hardware like one above should be enough for my needs ?
                  What backup type and software do you suggest ?

                    Re: New Exchange 2007 Server (software and hardware)

                    One that is exchange aware (BackupExec, BackupAssist...)
                    If it isnt you are left with zillions of log files

                    Beyond that, it depends on your backup frequencies, retention periods, SLAs, maintenance windows and any other factors.

                    Seriously, hire a good consultant to analyse your current infrastructure and requirements and at least plan, if not implement, the migration

                      I won't do the migration myself (I don't have the experience/knoledge for this). I just want to aproximate the amount of money involved in this. If it profitable for us, of course a professional will do this.

                        The change from Exchange 2007 to 2010 is not as huge as the change from Exchange 2003 to Exchange 2007 or higher. There are some differences, but if you have solid experience in 2007 then those skills will move across to 2010 easily.

                        I wouldn't dream of putting a new server with new licences at 2007 level. You immediately take 3 or 4 years off its useful life with support from Microsoft. Only if licences are already owned do I do Exchange 2007 deployments.

                        Microsoft have provided resources on how to scale Exchange 2010, including calculators and some overview of the typical hardware required. That will give you a good start.

                        The same rules apply as with other versions - storage, storage, storage. The most gains are from money spent on Storage. Then RAM then processor.

                          In the end decided that hosting our mail service to a 3rd party is the best option (especally that we got a good deal).
                          Thanks all for support.
