Referring to the SRND ; here is what we found;
http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/srnd/collab10/collab10/presence.html
referring to this section; "Instant Messaging Storage Requirements"
The minimum storage requirements (in bytes) for message archiving per month for Cisco Jabber users can be calculated as follows:
(Number of users) ∗ (Number of messages/hour) ∗ (Number of busy hours/month) ∗ (600 + (3 ∗ Number of characters/message))
The message archiving requirements above must be doubled if Enable Outbound Message Logging is enabled on Cisco IM and Presence compliance configuration.
The minimum storage requirements (in bytes) for persistent chat per month for Cisco Jabber users can be calculated as follows:
(Number of users) ∗ (Number of Persistent Chat messages/hour) ∗ (Number of busy hours/month) ∗ (700 + (3 ∗ Number of characters/message))
Quoting the same doc; refer to the following table to get more idea;
Table 20-4 Examples of Cisco Collaboration Client Message Logging Storage Requirements
Profile | Number of Users | Number of Messages per Hours | Number of Busy Hours per Month | Average Size of Message | Message Archive Storage Requirement | Persistent Chat Storage Requirement |
|---|
Light | 1500 | 10 | 200 | 100 | 2.7 GB | 3.0 GB |
Medium | 2500 | 15 | 200 | 250 | 10.2 GB | 10.9 GB |
High | 2500 | 25 | 200 | 500 | 26.3 GB | 27.5 GB |
