Newbie needs some direction with Exchange Server 2007 RRS feed

  • Question

  • I am in school and I have been given an assignment that is kinda hard for me.  I am not asking for answers but I am asking for direction.   If you guys can point me to some research that will help me It would be much appreciated.  Here is the scenario:

    Your organization plans to open a remote location that requires a server to host Exchange Server 2007
    with the CAS, Hub Transport, UM, and Mailbox roles. Your Senior Administrator has assigned you the
    task of choosing the hardware to support this server. Using the links below and internet research, design
    a server capable of hosting the previously mentioned roles and 1,000 mailboxes. Choose a processor,
    hard drive, and RAM.

    Here are the questions associated with the scenario:

    Questions
    1. What is the total cost of the server you designed?
    2. Would you recommend a multiple core processor? If so, why or why not?
    3. What is the minimum amount of RAM necessary?
    4. Would you recommend a RAID setup? If so, what RAID level? If not, what would you suggest for
    fault tolerance.

    Your guidance and expertise is much appreciated.  Just point me in the right direction for research....

  • Hi Mikenater,

    Thank you for your question.

    1. What is the total cost of the server you designed?

    A:the total cost depend on the price of hardware and software in your country, we didn’t give an exact answer.

    2. Would you recommend a multiple core processor? If so, why or why not?

    A: I suggest we use the multiple core processor, because Exchange consume much hardware resources. including CPU,RAM and so on, when we use multiple core processor, Exchange will deal with a mount of request without no response. It is convent for us to manage Exchange server.

    3. What is the minimum amount of RAM necessary?

    A:  AS you said that a server to host Exchange Server 2007 with the CAS, Hub Transport, UM, and Mailbox roles. The minimum amount of RAM is 4GB. However, if there are 1000 mailbox, we suggest the RAM is higher, we could refer to the following link:

    4. Would you recommend a RAID setup? If so, what RAID level? If not, what would you suggest for fault tolerance. 

    A: Exchange 2007 have high availability for database, for example LCR,CCR,Scc or SCR, we could refer to the following link:

    If there are any questions regarding this issue, please be free to let me know. 

    Best Regard,

  • In addition to the good links above, some general tips.

    Storage Requirements

    When we evaluate mailbox requirements (and if we have a previous mail system as an example), we consider the number and size of existing mailboxes but also the profile of users. For example, how many messages sent/received per day? This has an effect on the I/O (input output) requirements for the hard drives. Number of messages is important but also the type. If content is essentially text, and nothing else. messages will not take up much space. If sending / receiving of large attachments is the rule, then storage requirements will be higher.

    RAID

    One recommendation for Exchange 2007 was to have 1 volume for the OS (Windows Server), 1 volume for the database and 1 volume for the logs. Ideally, the volumes would be separate RAID arrays (and not just different partitions on the same physical disk). I've seen RAID1 recommended for the OS, RAID 5 for the database and RAID 1 again for the logs.

    In reality, for a small organization with limited requirements (infrequent I/O operations), you might be able to have database and logs on the same volume. It's still a good idea to separate OS and Exchange. 

    Except for LCR (almost never used in practice from what I understand), CCR, SCC and SCR all require at least two servers and add a certain level of complexity - and cost.

    So (as you may already know), RAID provides DISK redundancy (I lose one disk but the server can still function) and the clustering methods (SCR, CCR, etc.) provide SERVER redundancy (I lose one server but my organization can still function - for email).

    It looks like you only need to plan for disk redundancy in your assignment.
