What is the formula used to calculate the size of the PSM server?

The formula for calculating the size of the PSM (Privileged Session Manager) server is based on the expected number of sessions, their average length, and the average bit rate. The correct choice combines these factors systematically to ensure that the server has sufficient capacity to handle the expected load.

By using the maximum number of sessions alongside the average length of each session and the average bit rate, this formula accounts for both the duration and the data rate of the sessions being recorded. The addition of 20 GB serves as a buffer for the system's operational overhead, ensuring that there is enough storage not only for the recorded sessions but also for any additional functionalities or future expansion. This is crucial for maintaining optimal performance and ensuring that the system does not become overloaded or run out of storage space.

The other options do not encompass the necessary elements in a comprehensive manner. For example, some formulas may focus solely on recorded sessions or may not incorporate the average bit rate, potentially leading to underestimations of the required storage, thus highlighting why this particular formula is critical for accurate capacity planning in a PSM environment.
