  • add exchange 2k7 to exchange 2k3 env + config

    Hi,

    I've a few question about add EX2K7 and config EX2K7.
    i use EX2K3 STD SP2 today and i bought a new Server that i'm going to install an EX2K7 64BIT STD my first question
    1.after that i installed the new EX2K7 server on the domain can i start to move mailboxes while the users still working and there outlook is open? or i need to close the outlook for every user that i move?
    2.from right perspective i use 2X146GB 15K Mirror to system OS + Exchange binaries
    2X146GB 15K Mirror to exchange Logs database
    and about the database itself what is better for performance a 4X146GB 15 is Raid5 or 4X146GB 15K in Raid10?
    3.today i've about 70 users and my DB is about 70GB.
    is it will be wise to create a separate database for every department that i have (Sales,Production,Accounting,Management)?

    THX.

    Personal thoughts:
    1. Just like every version of Exchange the mailbox isn't accessible while it moves. For the best user experience I would make sure they have outlook closed otherwise it could hang. Having said that why not schedule the move overnight or do it when they aren't in?
    2. There are plenty of choices and thoughts about RAID on google. One is here (LINK) but you would be best to read up yourself.
    Best performance is 1 mailbox database per storage group with each of these on separate drives.
    Diskpart too:

    3. With what you have I would keep it all in one database as per #2. Unless there are specific reasons why you want more that we don't know about.
    cheers

      I would generally concur except for point 3. Since Exchange 2007 Standard allows 5 databases (IIRC) rather than the previous 1 and since you can apply database level limits and policies, it makes sense (to me anyway) to have smaller departmental databases.

          Ossian, 5 databases would mean 5 x the attempts to read/write to the same logical disk wouldn't it, would there be performance hit as opposed to 1 DB having direct read/write access? Plus store.exe could hold more of a single DB in RAM rather than smaller bits of many (the last be may not be much of an argument either way) Anyone else have input for this too?

            That could well be the case, although I would think the actual amount of RW activity should be pretty much the same since the amount of data in/out will not change.

            Given the relatively small load, how much difference will it make vs the possibly improved admin of separate dbs

            (Note this is likely to degenerate into "how many angels can dance on the head of a pin" I think we need Sembee's definitive input )

              Sure, that sounds like the best course of action!

                Alas this wasn't the only place this question was asked.
                I responded in another place.

                "You can't move a mailbox while Outlook is open. Therefore if you want to move a mailbox then tell the user to close the mailbox.

                On that number of users, and the size of the store, you will see very little difference between RAID 10 and RAID 5. I would also say that on the number of users splitting up the database in to four isn't going to gain you a great deal. I would consider splitting it in two, but that is about it.
