Capacity Definitions

The Cisco Unified MeetingPlace system refers to various forms of capacity. The following definitions are provided to help you understand and calculate the usable capacity of your system:


Licensed Capacity

Refers to the number of ports for which you have a license.


Physical Capacity

Refers to the capacity of the media and web servers associated with your Cisco Unified MeetingPlace system.

  • Voice capacity: This is equal to the number of Cisco Unified MeetingPlace Audio Blades subject to the Global Voice Parameter.
  • Video Capacity: This is equal to the number of Cisco Unified MeetingPlace Video Blades subject to the Video Global Parameter. The Global Video Parameter determines the bandwidth supported by Cisco Unified MeetingPlace video conferencing:
    • "Standard Rate" allows video connection with bandwidth from 64 Kbps up to 384 Kbps. System capacity is calculated as follows: 48 ports if single blade, or 40 ports/blade * n blades.
    • "High Rate" allows video connection with bandwidth from 64 Kbps up to 2000 Kbps. System capacity is calculated as follows: 24 ports if single blade, or 20 ports/blade * n blades.
    • For more information, see Video Endpoint Compatibility.

Note: If the physical capacity is less than the licensed capacity, the system generates an alarm each time it starts up or whenever the capacity changes. To prevent this alarm and bring the licensed capacity in line with the physical capacity, set the capacity override values fields for voice and video on the Meeting Configuration page in the Administration Center. This changes the effective licensed capacity to match the override values.

Note: Unless the system is audio only, Cisco does not recommend provisioning a system with fewer video blades than audio blades. The capacity on the audio blades, without attached video blades, may not be predictably reliable and usable.


Global Voice Parameter Supported Number of Audio Ports Maximum Number of Supported Ports per System (a system consists of 1 Application Server, 2 Web Servers, 6 Audio blades, and 6 Video blades)

G.711

250 per Audio Blade

1500

G.711, G.729, G.722, and iLBC codecs, with transcoding and echo cancellation enabled

166 per Audio Blade

996

G.711 and G.729 with echo cancellation disabled

Note: We do not recommend this option for wide area networks or long distance callers.

250 per Audio Blade

1500


Video Global Parameter Number of Video Ports Maximum Number of Supported Ports per System (a system consists of 1 Application Server, 2 Web Servers, 6 Audio blades, and 6 Video blades)

Standard Rate

  • Single Video Blade system = 48 ports
  • Multiple Video Blade system = 40 ports/blade * n blades

For example, two Video Blades = 80 ports.

240

High Rate

  • Single Video Blade system = 24 ports
  • Multiple Video Blade system = 20 ports/blade * n blades

For example, two Video Blades = 40 ports.

120

Available Capacity

The effective licensed capacity modified by the value of the global audio mode or the global video mode. If the physical capacity is less than the licensed capacity, the system schedules resources based on an inaccurate count of ports.

  • In the higher capacity setting of each mode ("G.711, G.729; 250 ports/blade" for voice or "Standard Rate" for video), the available capacity matches the licensed capacity.
  • You can increase the function of each port at the expense of capacity by using the lower capacity setting. For voice, the lower capacity setting adds additional codecs at the cost of one third of the number of voice ports. For video, the lower capacity "High Rate" mode allows higher bandwidth at the cost of one half of the number of video ports.
  • There are "capacity override" parameters in the Administration Center which should be used if the licensed capacity exceeds the physical capacity. Use of these parameters allows the system to operate by using the correct system capacity. See "Media Resource Configuration Page" in the "Administration Center Page References for Cisco Unified MeetingPlace" module in the Cisco Unified MeetingPlace Release 7.1 Configuration Guide at http://www.cisco.com/en/US/products/sw/ps5664/ps5669/products_installation_and_configuration_guides_list.html.

Schedulable Capacity

The available capacity plus the number of overbook ports, minus the number of floater ports. We recommend that you set the number of overbook and floater ports to a percentage of the available capacity, so if the available capacity changes (such as by changing the mode) you can adjust the overbook and floater ports accordingly. Overbooking parameters only apply to the MeetingPlace Scheduling deployment model, Floater port settings are needed for either MeetingPlace or Webex Scheduling deployment models.

Web Server Capacity

Cisco supports a maximum of six Web Servers for Release 7.1; three Web Servers for internal meetings and three Web Servers for external meetings.

Web Server capacity refers to the number of ports that a Cisco Unified MeetingPlace Web Server can support. Web Server capacity depends on the following:

  • Type of hardware that you are using
  • Features and applications that you have installed, for example, Secure Socket Layer (SSL), recording, or integrations with scheduling clients such as Cisco Unified MeetingPlace for Outlook.


Cisco Unified MeetingPlace distinguishes between:

  • The number of web ports supported per system.
  • The number of web ports supported per Web Server.
  • The number of web ports supported per meeting.


Note: For the purposes of these descriptions, a "system" is comprised of the following:

  • 1 Application Server
  • 2 Web Servers
  • 6 Audio blades
  • 6 Video blades


Supported Number of Web Ports Per System

A system is comprised of one Application Server, two Web Servers, six Audio blades, and six Video blades. The following numbers assume that the web ports (or number of web sessions) are spanning across multiple meetings.

One system supports the following:


Web Conferencing Configuration Supported Number of Web Ports for MCS-7845

No SSL, no recording

1000

SSL or recording enabled

1000

Supported Number of Web Ports Per Web Server

Table: Number of Web Conferencing Ports Supported for 7835 and 7845 H2, I2, I3 Servers lists the number of web conferencing ports supported per server for the following models:

  • Cisco MCS 7835-H2
  • Cisco MCS 7835-I2
  • Cisco MCS 7845-H2
  • Cisco MCS 7845-I2
  • Cisco MCS 7845-I3


Note: The 7845-I3 server is only supported for Release 7.0.3 (MR2).


These numbers work for systems with Secure Sockets Layer (SSL), Cisco Security Agent (CSA), scheduling with Microsoft Outlook or IBM Lotus Notes, outdial, and various audio and video codecs. The web capacity is limited only by whether you have recording enabled on the system.

Table: Number of Web Conferencing Ports Supported for 7835 and 7845 H1, I1 Servers lists the number of Web Conferencing ports supported per server based on the most common configurations for the Cisco MCS 7835-H1, Cisco MCS 7835-I1, Cisco MCS 7845-H1, and the Cisco MCS 7845-I1. For these servers, the web capacity is limited by whether the system has SSL and a scheduling program installed.

Tip: Remember that the maximum supported number of web ports or web users per meeting is subject to the maximum number of audio ports per meeting. Audio meetings are restricted to 500 ports due to the rate at which a single Audio blade can accept traffic. For a quick reference table of various system capacities per Cisco Unified MeetingPlace configuration, see System Capacity Quick Reference Tables Cisco Unified MeetingPlace does not support a single meeting spanning multiple servers.

Supported Number of Web Ports Per Meeting

The maximum supported number of web ports or web users per meeting is subject to the maximum number of audio ports per meeting. Audio meetings are restricted to 500 ports due to the rate at which a single Audio blade can accept traffic. For a quick reference table of various system capacities per Cisco Unified MeetingPlace configuration, see System Capacity Quick Reference Tables


Note: Cisco Unified MeetingPlace does not support a single meeting spanning multiple servers.

About Monitoring the Capacity and Usage of the System

Cisco Unified MeetingPlace has three reports that assist you in determining the capacity of your system. See the Port Utilization Report Page and the Unattended Ports Report Page in the Reference Guide at http://www.cisco.com/en/US/products/sw/ps5664/ps5669/prod_technical_reference_list.html for descriptions of these reports. These reports track the following:

  • Port utilization
  • Unattended ports
  • Amount of minutes used monthly

Cisco recommends a Port Utilization averaging 80%, when system utilization is higher, then adding additional port capacity is recommended to keep system from growing to 100% utilization which will block callers at peak periods.
