Cisco Unity Connection 7.x Supported Platforms List [Cisco Unity Connection]

This document provides details about the platforms supported for Cisco Unity^® Connection, including those shipped by Cisco and those provided by customers, as well as platforms supported for migrations.

The Cisco Unity Connection installation application prevents installation on servers that do not meet the exact specifications or models listed on the Cisco Unity Connection 7.x Supported Platforms List.

Platform Overlays for Cisco Unity Connection 7.x

Platform overlays are generic platform categories based on the configuration of processors, hard drives, and RAM. Each platform in this document corresponds to an overlay based on its configuration of these components. Table 1 defines the overlays for Cisco Unity Connection 7.1 and 7.0, and lists the currently shipping servers for each overlay. Cisco ships Cisco Unity Connection servers with the operating system and Cisco Unity Connection application preloaded. Further technical details and specifications for each of these servers, as well as technical details and support limits for older media-convergence-server (MCS) platforms supported by Cisco Unity Connection 7.x, are further described later in this document. Cisco ships the servers listed under "Co-resident Configuration" with the operating system as well as the Cisco Unity Connection and Cisco^® Unified Communications Manager applications preloaded. For technical details and specifications for the co-resident servers, please refer to the data sheet at: http://www.cisco.com/en/US/products/hw/voiceapp/ps378/products_data_sheets_list.html.

Note: The Cisco MCS 7828 Media Convergence Server is supported for Cisco Unified Communications Manager Business Edition only. This server is not supported for repurpose in Cisco Unity Connection 7.x.

Note: Cisco Unity Connection supports HP servers in the form of software only. Please refer to the HP Server Solutions page for more information about HP server configurations: http://www.cisco.com/en/US/prod/collateral/voicesw/ps6790/ps5748/ps378/product_solution_overview09186a0080107d79.html.

Voicemail-Only Configuration Supports only telephone user interface (TUI) or voice user interface (VUI) and Cisco Unity Assistant clients connecting to the Cisco Unity Connection 7.x Server
Total number of available ports (Voice + Text-to-speech [TTS] + Voice recognition) per server	482	962	144 2	16
Total number of available ports of an active-active node	962	1922	2882	-
Total number of users with mailboxes	2,000	4,0003	10,0004	500
Number of Cisco Personal Communications Assistant users	2,000	4,000	10,000	500
Total number of corporate directory users (per standalone server or active-active node; up to 50,000 digitally networked users)	10,000	10,000	10,000	1,000
Integrated Messaging Configuration Supports clients including TUI, VUI, and Cisco Unity Assistant
Total number of available ports (Voice + TTS + Voice recognition) per server	245	485	725	16
Total number of available ports of an active-active node	485	965	1445	-
Total number of users with mailboxes	1,000	3,0003	7,5004	500
Number of Cisco Personal Communications Assistant users	1,000	3,000	7,500	500
Total number of active clients (Cisco Unified Personal Communicator + Third-party Internet Message Access Protocol [IMAP] + Cisco Unity Inbox)4	1,000	3,000	7,500	500
Number of Cisco Unified Mobile Communicator and Phone View users	1,000	3,000	7,500	50
Total number of corporate directory users (per standalone server or active-active node; up to 50,000 digitally networked users)	10,000	10,000	10,000	10,000

1 2 GB supports up to 2,000 directory names; 4 GB total is required for more than 2,000 names in the directory.

2 G.722 and Internet Low Bandwidth Codec (iLBC) codecs decrease the maximum number of ports supported by 50 percent for platform overlay 1 and the co-resident configuration. For platform overlay 2, the maximum number of ports supported is 36. For platform overlay 3, the maximum number of ports supported is 48.

3 Storage space is ~10 minutes per mailbox using existing 72-GB hard disk drives (HDDs).

4 This number assumes all Internet Message Access Protocol (IMAP) Idle clients. Refer to the note later in this document about mixing IMAP Idle and non-Idle clients.

5 G.722 and iLBC codecs decrease the maximum number of ports supported per platform by 50 percent.

IMAP Idle Clients

The calculations for the total number of active clients assume the use of IMAP clients that support IMAP Idle. Cisco Unified Personal Communicator, Cisco Unified Mobility Advantage, Cisco Unified Mobile Communicator, and the IBM Lotus Sametime plug-in do not support IMAP Idle. As a result, each active instance of each of these clients (that do not support IMAP Idle) that is accessing Cisco Unity Connection voice messages counts as four active clients.

Active-Active High-Availability Configurations

Cisco Unity Connection 7.x supports active-active high availability. In this configuration, a single high-availability node consists of two media convergence servers, each with up to 144 ports (depending on the MCS model). The total number of node ports is additive (meaning a single node can support up to 288 ports), but the total number of users supported is applicable only to the primary server.

RAM Requirements for the Media Convergence Servers When Digital Networking and Voice Recognition Are Configured

Cisco ships the Cisco Unity Connection Overlay 1 platforms (Cisco MCS 7825) with 2 GB of memory. When digital networking and voice recognition are configured, and when you are using one or more Cisco MCS 7825 Servers, 2 GB of additional memory is required in the Cisco MCS 7825 Servers when the sum of contacts, users, distribution lists, locations, personal contacts, and personal distribution lists exceeds 2,000. You can increase the number of digitally networked users to 10,000 by adding 2 GB of memory to the platform for a total of 4 GB.

The Cisco MCS 7835 Overlay 2 platforms for Cisco Unity Connection 7.x require 4 GB of RAM.

Platforms Qualified for Use with Cisco Unity Connection

Cisco Unity Connection 7.x is shipped from Cisco as an appliance on the Cisco 7800 Series Media Convergence Servers ending in the suffix "UCB2" or "UCB1". However, Cisco Unity Connection supports upgrades from some media convergence servers shipped for previous versions of Cisco Unity Connection and Cisco Unity messaging. Tables 2 through 26 outline the supported media convergence servers for Cisco Unity Connection 7.x as well as hardware specifications, and, where applicable, required hardware changes for Cisco Unity Connection 7.x to support the product. Table 2 is a condensed list of Cisco Unity Connection 7.x currently shipping supported platforms with noted required hardware changes. Where possible, Cisco product numbers are listed in the tables for hardware upgrades, as are original-equipment-manufacturer (OEM) product part numbers for direct sourcing of the equipment.

Note: Because of changes in disk-space requirements in Cisco Unity Connection 7.x, if you are running Cisco MCS 7835 first- or second-generation models (H1, I1, H2, or I2) and if you want to install Connection in a cluster (active-active) configuration, you must upgrade your hard disk from 2 x 72 to 2 x 146 GB. For details, refer to Tables 2 through 26 for the specific models and required HDD spare part numbers.
