Memory

Disassembling the Lenovo Thinkpad T520 is easy, which makes upgrading the device a simple procedure. As described in my previous article I bought a T520 with only 2 GB RAM in order to replace the shipped memory with two 4 GB modules from Kingston. I also bought Intel’s mSATA SSD 310. This is a short description of the upgrade and installation procedure.

Here are some very simple guidelines that help determine how much memory a particular server actually needs in order to perform well. Of course, these are just rules of thumb, but nevertheless they might come in handy.

Even with the most meticulous design, the day will come when your farm’s capacity is not sufficient any more. User numbers increase, applications become more resource-hungry and the amount of data to be handled increases steadily. So what do you do? Simply more of the same, i.e. buy more servers and add them to the farm? That is one way of increasing capacity, but it is not the only one and therefore may not be the best.
