cPanel / WHM Overselling



Quote:


Suppose kumquat creates 23 Accounts, each with a minimum of 1 GB of Disk Space
assigned ( Allocated ). That effectively gives kumquat a potential of 23 GB of
disk usage across the 23 accounts ( @ 1 GB / account ). Once the total disk
space used by all the accounts exceeds 1 GB ( the Max Disk resource limit),
kumquat can no longer create accounts. However, his accounts can continue using
disk space, up to their disk quota ( the Allocation ). The resource limit does
not apply to the account's use of their resources, only kumquat's ability to
sell more accounts.
The resource limits only apply to a reseller's ability to sell, upgrade and
downgrade accounts. It is not used to govern suspension of a reseller or his
accounts.


Your customers could be using a lot more then what they are allocated. A customer with 1GB of reseller account overselling enabled, could create an account with 100GB of disk space allocated to it and actually use up the entire 100GB of disk space without any problems. No notifications or alerts of any kind sent to the server admin or reseller.
The whole point of overselling was to sell more then what you have in order to squeeze every bit of "available" resources allocated to the reseller, not use up the entire server's resources.

That is pretty nasty to say so myself. A customer could get away wth using 100gb of space without any notification! That would be pretty aggravating to find during a manual server audit to figure out what the heck is using up all of the available hd space. Those poor overselling hosts. I doubt they will care though, and will continue down the road they are already on.

cPanel has definitely got to fix this. It would be rather annoying to have to constantly monitor your user's resource usage to make sure that they never go over the limit.

As of right now they do not have any plans for fixing it, rather adding notification feature as well as changing the explanation of the "overselling" bit of the cpanel/whm reseller center.

This is a heads up to all the web hosts offering "Overselling Enabled" reseller packages. Your customers could be using more then their allocated resource limits, a lot more.
A customer with 10gb of bandwidth and overselling enabled, could simply create a 1000gb of bandwidth package, assign it to an account and actually use up the entire 1000gb with no notification to you at all. Applies to disk space and bandwidth.
Just a heads up

Again, almost all web hosting companies offer "overselling" enabled reseller plans including you. This affects all those packages with "overselling" enabled. cPanel has designed a extremely poor overselling system that allows the user to exceed the limits.

This is why I don't do overselling ^_^

Serves them right for overselling for a quick buck.

<< removed >> Overselling is the standard business model for any service. Do you think the phone company has 1.4MB of bandwidth for every single DSL user? Does the water company have 70psi of water pressure for every household to use at the same time? Does the power company have 150Amps available to every household on the grid? No they don't. Not every webhost has the full space and bandwidth pre-purchased for every single hosting account. Dedicated bandwidth and storage space are available with a Dedicated server, that is what that means. Everything else is oversold somewhere down the line no matter how many people lie about it and try to obscure a really simple to understand concept. When a company sells a reseller account without overselling enabled, then they are lying to you by calling it reselling and cheating you by jacking up prices on a regular hosting account.
