Sizing servers

Discussion in 'MCSE' started by Richard Sherman, Jul 31, 2003.

  1. I'm just starting a job where one of the requirements is to provide
    technical assistance to the sales team. Namely advising on server
    requirements for small to medium size customers running 2000 with
    exchange and ISA. My experience has been in 2nd line support on
    existing servers/networks.
    My question is where can I find help with deciding on server
    requirements?
    I've tried using google but I'm obviously not very good with it cos I
    seem to get hundreds of irrelevent pages come up whatever way I try to
    phrase it.

    For my company's exchange setup, we have the following for 115 users ( 150
    at one point )

    2 servers setup like this....

    2gb of RAM
    1- 36gb OS
    1- 36gb Exchange
    2- 74gb mirrored for Logs
    1 - external Array with 420gb capacity (array is dual bus) split into two
    210gb RAID 5 drives.
    Dual 2.4 Zeons w/ HT.

    2nd server connects to the other half the array.

    We keep half the company on one and half on the other so not everyone loses
    their email in the event of server failure and we have an Exchange Front End
    server for this setup for OWA.

    You need to consider whether the company will be using mailbox quotas to
    determine disk space, but definitely for performance I wouldn't get anything
    lower than 2ghz and 2gb of RAM for anything more than 75 users. We cap ours
    at 1.5gb because anything over that, Outlook starts exhibiting problems.

    What we have is overkill but where I work we are extremely paranoid and have
    redundancy for all critical systems, so for this it is better to overkill if
    possible as having an exchange failure is not fun to go thru when you don't
    have redundancy, trust me I know.

    ISA Setup -

    When loading the ISA mmc, it brings down a P3 1.1ghz and 1.5gb of RAM for
    about 15 - 20 sec and we only use it for DMZ, VPN (not more than 10 users at
    any given time) and for terminating SSL for a couple of internal web/SFTP
    sites, and of course performance thru a TS session is obviously worse even
    on a 100mb LAN.

    so go figure.....

    if it is sme's with under 50 users i'd go for sbs2k as the solution, bearing
    in mind the limitations of it.
    As for the actual server, the only limitations that i usually find myself
    working to is budget.
    Hence it's as much as i can get for the available budget. i appreciate that
    this sounds a bit simplistic but in my experience it has usually come down
    to this.
    Budget apart, i'd look at the type of industry.. for instance if they are in
    the print industry they will require a lot of hard drive capacity because of
    file size.

    very true about the budget.

    ahh, tell the morons to share out files in a central location so they don't
    email them if they don't have to.

    we recently had ID10T try and send a 100mb file thru email to our remote
    location NY that has a 1mb/1mb DSL line and then CC'd someone that sits
    across from him. Had to give him the big brother talk and this is of course
    after we put a 10mb limit on incoming attachment sizes.....

    enough ranting...

  7. By being the best that applied for the job :)

    I have MCSE NT4 and will shortly finish my MCSE 2000. My only lack of
    qualification for the job is a lack of experience with choosing server
    requirements. The majority of the job is doing installs, upgrades and
    fixes for the customers. Which is what I've been doing for the last 7
    years (Unix, NT4 and 2000), but unfortunately the systems were spec'd
    by our HQ, so I don't have that experience.

    I will have support from my predecessor in the post who has been
    promoted within the company. I just wanted to try and get ahead before
    I start next week.

    no, you'd use that as a minimum. then you would determine your number of
    users and adjust your hardware accordingly.

    No, but if I were clueless as to what my minimum requirements were I
    would read the documentation. It is there for a reason.

    i'd disagree to an extent.

    minimun reqs are a sales gimick.
    think of it this way.
    to drive an F1 car the basic req's are 2 arms 2 legs and the power of sight.
    to drive like schu, it takes a good bit more

    so wrong

  18. Excellent data!
    Would it be better to put the full company email (replicate) on each of the
    2 servers and then just assign half of the company to one amd the other half
    of the company to the other server for load balancing and full email/data
    available if one server goes down?

  19. No, you laugh at the requirements MS lists and at a minimum triple it!
