This article provides guidelines and examples to aid in sizing Unified CMBE 6000 suite of applications for UCS C200 server .

Application Co-residency Support and Server

  • Co-residency of 3rd-party application VMs - such as TFTP/SFTP/DNS/DHCP servers, Directories, Groupware, File/print, CRM, etc. - is not supported with Unified CMBE 6000 at this time. These applications may be placed on a separate physical server from Unified CMBE 6000 UCS C200 server.
  • Co-residency of non-UC VMs is not supported at this time. These applications may be placed on a separate physical server from UC.
  • All component applications must use a supported virtual machine OVA template.
  • All applications require a 1:1 mapping of VM vCPU cores to physical CPU cores.
  • For Unity Connection VM one CPU core must be idle/unused (it is actually being used by ESXi scheduler).

Redundancy and Failover Considerations

Application-layer considerations (such as Unified CM Cluster over WAN) are the same for Unified CMBE 6000 as well as non-virtualized (MCS 7800) deployments.

However, since there is no longer a 1:1 relationship between hardware and application instances, "placement logic" must be taken into account to minimize the impact of hardware unavailability or unreachability:

  • Avoid placing a primary VM and a backup VM on the same server, chassis or site
  • For failover groups, avoid placing all actives on the same server, chassis or site
  • Avoid placing all VMs of the same role on the same server, chassis or site

Sizing Example

This section shows a sample system configuration based on following the Design and Implementation Checklist for the following set of customer requirements:

  • General Requirements
    • 500 Phones, use Cisco TFTP server with hardware redundancy
    • 500 Messaging users with high availability
    • 500 users equipped with Cisco Unified Personal Communicator (CUPC)
    • Contact Center with 45 agents and 5 supervisors with high availability

Following two servers would be required to host the Unified CMBE 6000 suite of applications with full hardware redundancy:

  • Two Cisco UCS C200 General-Purpose Rack-Mount Servers
