Hardware selection

Several factors affect what type of hardware to select, such as whether the cluster is going to support many virtual machines with fewer resources or serve few virtual machines with more resources. A cluster focused on many virtual machines needs to have a much higher processor core count, so our goal should be to put as many cores as possible per node. When a cluster is focused on few virtual machines, with a lot more users per virtual machine, we need to have a large memory. Thus, a system with a smaller core but a greater amount of memory is much more appropriate. Also, a cluster can focus on both types and create a hybrid cluster environment. A hybrid environment usually starts with an entry-level hardware setup and ...
