Introduction

Virtualization has emerged as a leading trend in the data center. Organizations are embracing the virtualized data center for a variety of reasons, including total cost of ownership (TCO), consolidation, operational efficiency and flexibility, disaster recovery and business continuity, security, and reduced carbon footprint. Cisco is committed to leading the transition toward the virtualized data center through innovative products and solutions, including support for Cisco Unity messaging on the VMware ESXi platform, part of the VMware Infrastructure suite.

Deploying Cisco Unified Communications on VMware ESXi delivers the following advantages:

  • Allows customers to extend the benefits of their virtualization and storage data center investments to Cisco Unified Communications.
  • Maintains the same predictable scalability provided by running the Cisco Unified Communication applications on a physical server.

Cisco Unified Communications are real-time application, which makes it more difficult to virtualize than traditional data-centric applications, such as database and email servers. Delivering this level of performance in a reliable, predictable, and serviceable manner requires some concessions, primarily around not oversubscribing the CPU, RAM and other resources.

You can virtualize many of the Cisco Unified Communication applications, such as Cisco Unified Communication Manager, Cisco Unity Connection, Cisco Unified Presence Server, Cisco Unified Contact Center Express and other Contact Center applications

You can also run a mix of virtual and nonvirtual machines, including the servers in a backup or failover pair. Also note that to virtualize Cisco Unified Communications applications, there is an additional support burden. Customers provide the hardware, VMware ESXi software, and are responsible for coordinating support for these components, including provisioning and performance troubleshooting. Customers who are unwilling to take on such support may be better candidates for deploying Cisco Unified Communication applications on physical servers.


Hardware Requirements

The following hardware requirements apply to the currently-supported Unified Communications applications:

  • The hardware must be the half-width B-200 blade, with the Intel E5540 CPU or greater.
  • SAN storage must be used.
  • The SAN array must on the VMware list of supported SANs.
  • SAN connectivity must be fiber channel.
  • SAN array disks must be fiber channel or SAS with 10k or 15k spindle speed.
  • No over subscription of of any resource is allowed.

A complete list of requirements is located here.
