John, just cause the machines we use to serve web content to our

afford, doesn't mean equipment that other people use is inferior, or
worthless.

I have a problem with one of my machines, and have narrowed down that
it could either be the CPU, RAM or motherboard, but before I take it
back to the suppliers, I need to know what is wrong. They will switch
it on, and see that it works. But it's not taking the load that I
expect it could. In fact, it's not taking the same load as a machine
with a Intel E6750 Core 2 Duo & 4GB RAM. This server should be 2 - 4
times faster & handle 2 - 4 times the load of the E6750, yet it
doesn't and I need to know why. I don't appreciate being told that the
hardware I have if inferior.




Hi Rudy,

John is a veteran on this list and you could probably learn many things from him. I suggest you read:

(that could maybe explain why you seemed irritated by John!)

By the way, server grade hardware is just that: Meant to serv and include specific features for that particular kind of job. That doesn't mean that a workstation board won't be able to do a server job at all. Having said that, i manage servers since a long time and i can assure you that using serious server hardware with ECC translates in lower costs in the long run.

Sure you can still have problems with server grade hardware! But then, we could try to obtain statistics and MTBF to get a better idea.

But i find ECC error indicator to be invaluable and there a many other features that will help to pinpoint problems rapidly.

So Rudy, i can understand that you may have hardware problems and probably pressure to solve them but IMHO, it's just a classic example of TCO. And i read that you had problems with Dell servers, then try something else! It's OT but can say that i have many Tyan and HP servers in production and no problem at all.

Hope you'll solve your problem.
