Capacity Considerations

There are four variable criteria that need to be considered to successfully deploy a UCx virtualized software:

1. Amount of memory (RAM)
2. Size of the persistent storage (HDD or SSD)
3. CPU processing power
4. IOPS (drive I/O operations per second)

The required criteria for these four variables can be computed based on four pieces of information as follows:

However, to simplify the process of determining the resource requirements for systems of various sizes, the following table shows the capacity specifications of the E-MetroTel hardware appliances and the resource sizing required to simulate that same environment.
