Proxmox Production Level Setup
There are several key pieces of information for the hardware that is being used in a network that an administrator should any time have access to: these include information such as the brand, model and serial number of a hardware component, when was it purchased, who was the vendor, when is it due for replacement, and so on. A proper tracking system can save a lot of time when any of this information needs to be retrieved. Each company is different; accordingly, the tracking system could be different. Nevertheless, the responsibility of gathering this information solely falls on the network manager or administrator. If there is no system in place, then merely creating a simple spreadsheet can be enough to keep track of all hardware-related information.
Several factors affect the process of selecting a type of hardware. For example, is the cluster going to support many virtual machines with smaller resources or will it serve a few virtual machines with high resources? A cluster focused on many virtual machines needs to have many more core counts. So our goal should be to put as many cores as possible per node. A cluster is focused on a few virtual machines; therefore, if there are many users per virtual machine, we need to have a large memory. Thus, a system with less core but large memory is much more appropriate. Also, with this, a cluster can focus on both the types and create a hybrid cluster environment. A hybrid environment usually starts with an entry -level hardware setup and then matures into an advanced-level setup as the company grows and budget becomes available. For example, a small company can start its cluster infrastructure with a stable desktop-class hardware and then gradually replace them with a server-class platform such as Xeon to accommodate the company's expansion. Since we are working with a clustered environment, we will assume that all our nodes are identical to each other. Therefore, we are only going to look at one node setup.
Do not let the word entry-level fool you to think that it is a substandard, under-performing cluster setup. An entry-level setup provides a balance between high-core and high-memory cluster hardware setup. It is usually a single CPU setup, which can be easily set up using commodity hardware. This is a setup where choices between desktop CPUs, such as i5 and i7, and server CPUs, such as Xeon, can be made.
