    websites per server ratio

    I see some websites are on servers that entertain, at times over 100 other domains. Isn't there a recommended level?
    Sure the servers' size and speed has something to do with such an equation, but a rough dosage from experience should not go missing...

    We are still working on building the hosting site and kind of offers/services we want to provide. Surely, we do not want to bangup the server with too many domains, no one should, really.

    Any ideas as to that magic ratio?

    Thanks!

    anywhere from 1-10000.

    It depends on what kind of website they are.

    If they are a medium usage website, we find that around 250-300 is a nice fit on a P4 2.4ghz server.

    hummm... have you actually tried to host. say, 9999 domains, even small ones on the same server, and it never dropped because of the number?
    Surely, there is a calculated risk built into the numbers you mentioned?

    Of course there is a risk. There always is.

    I haven't personally hosted a server with 9999 domains on it, but I have been handed servers with a couple thousand domains on them. But the servers was mainly used for parking the domains.


    As long as the domains are not very active and your server is setup right., you can add as many domains as you want within a reasonable limit.

    Also, as dual 2.4ghz xeon will be able to handle many more websites that a celeron 1.7ghz.

    How many accounts a server can handle is a very trivial matter as it depends on many things such as server specs, activity, content, etc.

    There could be 1000 domains attached to only 100 accounts. People could have multiple domains going to the same site, or seperate domains for subdirectories.

    There is no limit really. The only limit is on what the domains can do. You can have a server with 100 domains where apache fails regularly or you could have a server with 1000 domains that maintains 100% uptime.

    We've found the number of accounts is not really important. It's really a case of server load.

    As an example: we have one reseller server that has 400+ accounts that has an average server load of about .30. We also have one reseller server with less than 100 accounts that has an average server load of .40. They both provide the same basic "speed" for the clients.

    It's really about the ability to provide the needed resources regardless of the number of accounts. Don't worry about the number of accounts worry about keeping a stable server and fast performance.

    Summed it up exactly. There is no such thing as a set number, it simply depends on what sites there are. I'd suggest that you just keep an eye on how the server performs as you add accounts.

    Hi phoenix_aa
    There are no magic numbers because it's not a magical thing, it is common sense that dictates how many domains can be manage on a particular server.

    Server load is ultimately what governs the amount of domains, it certainly isn't the only thing however if you are maintaining acceptable server loads and the server speed is not affected it is safe to say that you have the right amount of domains on that server. That's about as magical as it gets.

    Yes its all about load, but then potential Customers have this list of queries...and often one of them is "How many domains per server ".... and answering "Depends on Load, can be from 1 to 10,000" is the wrong marketing answer.

    No customer is going to sit easy knowing that you are intending to host 5,000 domains on the same server he's on.

    then tell him the truth, that the server they will be on currently has X amount of domains and the amount of sites per server varies dependent on server load and resource usage and you constantly monitor your servers to ensure maximum performance of those servers and therefore they are never overcrowded and are always running at their best performance levels.

    Well, without going into all the high-pitch Sales stuff that marketing gurus keep blabbing about...which do you think is a better selling line...


    Sales Pitch-1
    =========
    That the server you will be on currently has X domains and will host a MAXIMUM OF 5000 domains, dependent on server load and resource usage and we constantly monitor our servers to ensure maximum performance of those servers and therefore they are never overcrowded and are always running at their best performance levels.


    Sales Pitch-2
    ==========
    We only have X domains right now on the server and Max we will ever host on that server is 100 domains thus ruling out all possibilities of overcrowding. This ensures your site always has abundant system resources available, and in addition we constantly monitor our servers for perfomance and resource usage.

    Sales Pitch-3
    =========
    That the server you will be on currently has X domains and will host a MAXIMUM OF 250 domains, dependent on server load and resource usage and we constantly monitor our servers to ensure maximum performance of those servers and therefore they are never overcrowded and are always running at their best performance levels.

    If you have to put a maximum on it the the above is more realistic than either of the 2 you just posted

    The number of domains has little or nothing to do with server performance.

    If I had two servers:

    One server has one reseller with over 180 domins/subdomains. Each one is only 2 pages and uses less than 5 Gb per month. Total serve bandwidth is 100 Gb

    I also have one server with a client with 3 domains that does 470 Gb of bandwidth a month and I add 97 accounts. Total bandwidth is 565 Gb.

    They both have 200 domains. Which server would you want to be on?

    It's server load and stability that counts.

    Bright-byte, agreed...250 domains is fine of course. Its the 4-figures number that's a bit scary.

    mgphoto, you are talking about ground reality on perfomance. We are already agreed on that, no second thoughts... a single Google site runs on 10,000 servers, so that part is amply clear.

    But as far as your question, should hosts stick that question in the New Customer Signup form, in the Banner Ad, in the Offers section or in responses to Pre-Sales questions.

    I really can't think of a good place to stick a question to a new customer on the lines of "Which server do you want to be hosted on considering present loads ? "

    we just give our clients two domains and get then use cheaper plesk lisence on each server for 100 domains....this keeps our cost down fairly and then prevents others clients from feeling the effects of a slashdotting

    also keep in mind when you design you plans so there tailored to your customer and to match the avaible resources of the server
