CUPS Server capacity

[Gordon Ross]

I've been scouring the CUPS documents to try to find the maximum number of users supported per server. But I've failed to find a simple table that says server type X supports Y users. (I understand that there are differences between the deployment method: i.e. full CUCM integration or just IM)

There is information about capacity in both the Deployment Guide and the SRND, but I can't see the wood for the tress.

Thanks,

GTG

Hi Ross,

Please have a look into Docwiki if it helps

http://docwiki.cisco.com/wiki/Virtualization_for_Unified_CM_IM_and_Presence#Notes_on_1000_user_VM_configuration

Number of “Jabber for Everyone” users = (Number of full UC users/Maximum number of full UC users) x

Maximum number of “Jabber for Everyone” users

For example, if you have 10,000 full UC users on a server that supports a maximum of 15,000 users, then

you are operating at 2/3 of the scale for UC, which means that 1/3 is available for “Jabber for Everyone” users.

The IM and Presence Service supports 25,000 users for IM-only mode, therefore, you can add 8,333 users

(25,000 x 1/3) through “Jabber for Everyone”. This amounts to a total of 18,333 users.

this is table 23.4 for above link

Cisco IM and Presence Service Platforms and Number of Users Supported 

Server Platform	Users Supported Per Platform in Full Unified Communications Mode	Users Supported Per Platform in Instant Messaging Only Mode
Cisco MCS 7816	3,000	7,500
Cisco MCS 7825	6,000	15,000
Cisco MCS 7835 or OVA equivalent	15,000	37,500
Cisco MCS 7845 or OVA equivalent	45,000	75,000
