Note:
- If you have more than 10,000 users in Cisco Unified Communications Manager, you must use the 5,000 user OVA template at a minimum, even if you plan to license less than 5,000 users of IM and Presence.
- The recommendations below only apply to single cluster deployments. For multi-cluster deployments, it is recommended that you use the 5,000 user VM configuration at a minimum.

Notes on 500 user VM configurations |
(top) |
| |
| This is a minimal VM configuration for use with Cisco Hosted Collaboration Solution.
Maximum capacity:
- 500 Full UC users
- 1,000 IM-only users
- 6 single nodes or sub-clusters
This VM size can be used when performing a DRS migration from a non-virtualized/physical server with a disk capacity of 80 GB or less (e.g. MCS-7825-H2).
If you are migrating from a physical server with more than 80 GB of storage space to a virtual machine with a user deployment size of either 500 or 2,000, see the Disaster Recovery System Administration Guide for more information.
