Hardware sizing made simpler
Posted by primalcortex on January 24, 2008
Suppose that you need to provide some hardware specifications for some web-servers.
Also suppose that the number of users are bigger than 300/500 users, how do you size the hardware if the software provider or you don’t know what might the load be?
Easy:
If a machine has 2 dual core CPU’s in reality it has 4… so you can save on 4/8 way chassi.
RAM, bigger than 3GB needs a 64 bit OS, and Application server, so take notice on that.
Number of machines? One or two is a bad idea. In the first case if it fails you have nothing, on the second case, one of the machines gets 100% of the load.. So three machines in a load balancing cluster is better…
