System Capacity Quick Reference Tables
This module contains the system capacity tables for the system.
Maximum System Capacity and Scalability for Each System Size
The following table lists the maximum capacity for each system size.
| Maximum Number | 50 Concurrent Users | 250 Concurrent Users | 800 Concurrent Users | 2000 Concurrent Users |
|---|---|---|---|---|

| Playback recordings of meetings that have ended | 12 | 63 | 200 | 500 |
| Recordings of meetings in progress | 3 | 13 | 40 | 100 |
| Calls per second | 1 | 3 | 8 | 20 |
| Conferences (assuming 2 participants per meeting) | 25 | 125 | 400 | 1000 |
 Tip | The maximum length of a meeting is 24 hours for all size user system deployments. |
 Note | When considering an upgrade, plan for the increased size of the data stores, as the original system and the upgraded system share data stores until testing of the upgraded system is complete and the original system is removed. |
For information about network bandwidth requirements for the various size user systems, see Network Bandwidth Requirements.
