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
Concurrent meetings at any given time (assumes there are at least two meeting participants)	25	125	400	1000
Calls connected during a one second time period	1	3	8	20
Participants in a single meeting for non-HA deployments at any given time. (Users can connect as audio-only, audio+desktop sharing, or audio+video+desktop sharing.)	50	100	100	100
Participants in a single meeting for HA deployments at any given time. (Users can connect as audio-only, audio+desktop sharing, or audio+video+desktop sharing.)	50	100	250	250
Participants in a single meeting who are sharing or receiving video	25	125	400	1000
Playback recordings of meetings that have ended	12	63	200	500
Recordings of meetings in progress	3	13	40	100

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.

Note

For new installations of Cisco WebEx Meetings Server Release 2.0, the ESXi hosts (Cisco UCS server) with the Admin virtual machine require 1.5 TB of disk space. The ESXi hosts (Cisco UCS server) without an Admin virtual machine require 1 TB of disk space. When you are upgrading to Cisco WebEx Meetings Server Release 2.0 from Release 1.x using your existing Cisco UCS servers, the ESXi hosts will need 1118 GB of free disk space if the UCS server has only the Admin virtual machine (primary or HA system) or 990 GB of free disk space if the UCS server has one Admin and one Media virtual machine (primary or HA system). Disk space can be local (DAS) or external (SAN or NAS). For complete details, see the "Resources Consumed by Cisco WebEx Meetings Server and the ESXi Host" section in the System Requirements.
