Cisco Expands UC Virtualization Support

Stand back….this is a pretty big announcement!  As of June 7, 2011 Cisco began support for some Collaboration (formerly Unified Communications) applications running in a virtual environment on hardware other than their own Unified Computing System (UCS). The is the first in hopefully many steps to come in widening support for benefits we often realize with typical desktop and server applications running on a VMware hypervisor. The details are as follows.


Cisco is pleased to announce expanded virtualization of Cisco Unified Communications starting Jun 7, 2011.

On Jun 7 Cisco will add two additional virtualized UC offers. Customers will then have three deployment options:

1. UC on UCS – Tested Reference Configurations

2. UC on UCS – Specs-based VMware hardware support

3. HP and IBM – Specs-based VMware hardware support

Phase 1 support begins Jun 7, 2011 and should include the following (see for final products and versions supported):

– Cisco Unified Communications Manager 8.0.2+ and 8.5.1

– Cisco Unified Communications Manager – Session Management Edition 8.5.1

– Cisco Unified Communications Management Suite

– Cisco Unity Connection 8.0.2+ and 8.5.1

– Cisco Unity 7.0.2+ (with Fiber Channel SAN only)

– Cisco Unified Contact Center Express and IP IVR 8.5.1

Support for additional products and versions will phase in over rest of CY11.

Specs-based VMware hardware support adds the following

– UC Compute support for UCS, HP, IBM servers on VMware’s hardware compatibility list and running Intel Xeon 5600 / 7500 family CPUs

– UC Network support for 1Gb through 10Gb NIC, CNA, HBA and Cisco VIC adapters that are supported by above servers

– UC Storage support for DAS, SAN (Fiber Channel, iSCSI, FCoE) and NAS (NFS).

– More co-resident UC VMs per physical server if more powerful CPUs are used

– Note that UC / non-UC / 3rd-party co-residency is still not supported.

– Note that hardware oversubscription is still not supported by UC.

– No changes to VMware product, version or feature support by UC


This most certainly gives us far more agility for the manner in which we deploy these applications. More info to come as I get it…
