Capacity is typically measured in Gigabytes (GB) or Terabytes (TB). It should include the total space required to support the current requirements, the space required to support growth, the space required for virtual machine swapfiles, and the additional slack space for snapshots, logs, and other virtual machine data.
In order to calculate the storage capacity requirements, you need to perform the following steps:
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...
