    Hi All

    Dunno if this is the appropriate forum for this and i apologise in advance if its not.

    At college we have been given a mock project to setup a small network with a server(s) with 12 clients. The company is hosting its own website in house.

    My questions are?

    Which would be the best server setup scenario?
    A. 2 identical servers with RAID 5 and backup facility with 1 acting as a failover


    B. If both are identical and one is acting as a failover, can it do other functions in the meantime instead of just sitting there


    C. 1 quite well speced server and 1 less speced server doing the hosting


    D. If option C above can the less speced server take over networking functions like DHCP, DNS etc if the main server fails, and can the less speced server backup to the main one.

    Confusing i know but any help would be appreciated

    Not confusing at all... but shouldn't you know the answers to these questions from what you've learned in the course?

    We have only just started server 2003 in a stand alone (typical first server) environment and there seems a few options here.

    Cost.

    I would find it very difficult to sell more than one server to a company that only had 12 clients. SBS can support up to 60 (approx) clients.

    SBS supports all the roles you have highlighted and if you spec the server with a hardware RAID 5 then that should be all you need.

    OK. Sounds good but the company is hosting its own website selling IT products to the public. So am i right in saying that if the server goes down, and we only have one, then they lose the website and the local network therefore becoming totally non productive.

    We really dont wanna lose that website or the lan. Hence my enquiries on a 2nd server setup.

    Keep it coming guys

    It depends how much redundancy they want, if there were a hardware failure other than a drive then the entire network would be down.

    Depending how important the networks and it's functions are to the business will clearly decide this. I wouldn't want all my employees twiddling their fingers for possibly a day or more and I wouldn't want my website to be offline either

    I'd go for the two identical, they both have to be capable of running all services should the need arise to failover

    With 12 clients and a webserver they don't need to be too high spec either to break the bank

    How much traffic is the website getting?

    If it is getting bombarded with hits then you are talking leased lines. When it gets to this level it may be a better option to outsource the webhosting.

    What are doing about email? No mention of this so far.

    For the project we have to assume that the website is popular and that the appropriate WAN connection is already in place. These items we can ignore as they are not required for the project. We can just start with the servers. And outsourcing the webhosting is not an option.

    As for email it states that all staff should have internal/external email access

    Ok, you need more that two servers then.

    Load balance two webservers (in a DMZ) and then you will have to configure servers for your LAN,I would say a SBS server would do nicely, but if not you would need a DC and a Mail Server at least.

    Expensive! :biggrin

    There are several options here but not much to work with.

    You need the following in your LAN:
    Domain controller (also hosting DHCP)
    Mail Server
    File Server

    You would be best to buy SBS to do this. I support 30 odd small business networks and the physical spec of the servers are high for fault tolerance. They have RAID 5 and also backup PSUs. None of the servers have ever gone down for more than hour over the past 2 years.

    For Your Web Server:
    The technologies used for the website can influence your options here. If you have a basic website then you can have a load balanced cluster (you would need at least two servers for this not including the SBS) however if your website has an online shop (say SQL based) then load balancing isn’t an option for the *whole* hosting setup.

    Probably best to install the website on one high spec server with RAID 5, backup PSU and more than one NIC. 8)

    So 1 high speced server with most if not all points of failure covered.

    Seems ok, I prefer SCSI RAID though (old school!) with its own controller card. Do you have enough ££ for the rest of the network? Remember you need another server. Also does that spec cover backup software as well? You can use Windows backup (free) but it doesnt have as much functionality as other backup software. 8)

    I guess it all depends on whether this is a business critical server which I would guess it was and in which case I'd always personally prefer the option to failover

    Why do I need another server? I thought creating one with full fault tolerance would be enough. I have found another, cheaper, better server with 2 of everything including a redundant PSU for £3525. Say another £500 for my 5 printers leaves me £6000 for my 12 PCs, a switch(s) any any cabling.

    What do you think?

    I bet your server doesn't have 2 mainboards?

    How important is it that this box is up and running 24/7

    Would the company be carrying out servicing and carrying onsite spares such as a mobo or are you going to include a 4hour response service 24/7

    I guess you can go to extremes with ensuring redundancy, business continuity and disaster recovery precautions.
