Capacity is usually measured in Gigabytes (GB) or Terabytes (TB). Capacity should include the total space needed to support the current, the space needed to support growth, the space needed for virtual machine swapfiles, and the additional slack space for snapshots and other virtual machine data.
In order to calculate the storage capacity requirements, you need to perform the following steps:
Determine the capacity required to support the current workloads.
Determine the capacity required to support future growth.
Capacity is calculated to support the current and future growth based on the design requirements as follows:
Current Capacity = 100 Virtual Machines x 100 GB = 10 TB
Growth Capacity = 25 Virtual Machines x 100 GB = 2.5 TB
20% Slack space = 12.5 TB x .20 = 2.5 TB
Capacity = 12.5 TB + 2.5 TB = 15 TB
Each virtual machine will have a swapfile or .vswp file that is created when the virtual machine is powered on. The size...
