Hello,

So, our company is growing rapidly and as any business that grows we need to start thinking about the future.

On average, we have been adding 2 servers every month. Now, our biggest concern with this amount of servers is that we cannot afford ANY downtime. Period. So far we have been very successful in preventing downtime.

This is due in big part to our servers. We try to prevent HD from crashing by installing RAID controllers in all of our servers.

As we consolidating our data centers, and moving all our servers into 1 place we want to implement a fail over solution via a loadbalancer.

The biggest problem that we are seeing is that WHM and CPANEL will not allow us to deploy on multiple servers.

So, has any one ever done this? and if yes, how? I am open to any suggestions.

best regards,

Alex K.

I know you can have the HSphere control panel with multiple server - but I am not familiar with CPanel sorry.

Hi,

Can you not use clustering? That way CPANEL won't know it's on more then one server

With Linux, I am not sure. I just know that in thory this should work. I have only done it with Windows 2000 Advanced Server

The term "clustering" in Linux in ambiguous. It could mean "Hot/Fail" (as in Windows 2000 where it is called active/passive or active/active - which is really the same thing), it could mean "Load Balancing Cluster", it could mean "Application Cluster" (ala Oracle or the like), it could mean "Computational Cluster" (ala Beowulf), or it could mean "Single System Image (SSI)".

I am going to presume that you are interested in Load Balancing Cluster. The easist way is to get something like an F5 (www.f5.com) and let it do hardware based load balancing. In that case, the individual nodes do not know that they are part of a "cluster" at all and the only real technical problem left is sharing of data.

If you are asking about something (especially an SSI cluster - my personal favorite), then the solutions would be very different.
