The difference is that this counter does not consider the size of the request, just the fact that it is a request. Like disk bytes/sec, this also measures the throughput of the system. This is the total number of read and write requests processed per second (commonly known as I/O operations per second or IOPS). This provides information about the throughput of the disk system and how busy it is.ĭisk transfers/sec is the rate of read and write operations on the disk. It's best to divide your average queue length by the number of spindles in your RAID group to get a more accurate number.ĭisk bytes/sec is the rate bytes are transferred to or from the disk during write or read operations. Typically, most Windows servers have very low overall CPU usage ( 5) can indicate an I/O bottleneck depending on the number of spindles (hard disks) in your RAID group. Let's go over the categories, some important metrics, and some guidelines on each one. Consolidation ratios can vary from as little as 2:1 to as high as 50:1 based on the total amount of resources that your VMs will require and the size of your ESX host servers. The combined results of these metrics will help determine your overall consolidation ratio (number of VMs per ESX host) and how many ESX servers you will need for the number of physical servers that you want to virtualize.

It is also important to gather metrics during critical business cycles (for example, weekly payroll processing or a monthly reporting process) where performance may spike. Gathering these metrics for a longer period of time gives you a better understanding of any performance trends that you may be experiencing that might not happen on a regular basis.

You should gather these metrics for a minimum of one week, and preferably over a one-month period of time. You should focus on four general performance categories: CPU, memory, disk, and network. Doing this before you start your project is important so that you do not run into any surprises that can cause problems during your deployment phase. By doing this, you can ensure that you properly size your virtual hardware and can avoid any bottlenecks on your ESX hosts. Measuring your current performance is necessary so that you can get a good idea of how your current environment is performing.
