The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This document provides system requirements for the Cisco WebEx Meetings Server, Release 1.1.
Cisco WebEx Meetings Server is automatically compatible with Cisco UCS servers that meet or exceed the specifications.
Note |
The following table suggests that you deploy your internal storage in a RAID configuration. For further information, see the "Installing VMware vSphere ESXi and Configuring Storage" section of the Cisco WebEx Meetings Server Planning Guide at http://www.cisco.com/en/US/products/ps12732/products_installation_and_configuration_guides_list.html. Also, note that for brevity, we use the acronym IRP for the Internet Reverse Proxy. |

This section lists the supported requirements for end users to host and access meetings.
Note |
The information in this document is more current and therefore supersedes the browser and system requirements in the end user help. |
Note |
You cannot record a WebEx meeting that was scheduled or started with an iPhone or iPad. |
This release of Cisco WebEx Meetings Server supports the latest version of WebEx Productivity Tools, which can be found on the Downloads page of your WebEx site. If you are upgrading to this release and have an older version of Productivity Tools installed, your older version will still work for scheduling and starting meetings but will not support the latest WebEx features. We recommend that you push out the latest .msi for the optimal experience.
Note |
If you have Java enabled, the Cisco WebEx Meetings Application will automatically download onto your system the first time you start or join a meeting. We recommend that you install the latest update for your Java version. |
This section describes the system requirements for the Mac.
CPU usage, memory, Ethernet, and hard drive requirements are described in the section for your system size. Select from the following sizes:

Note |
Co-residency with vCenter is supported with 50 and 250 user system deployments only. Co-residency with Cisco Unified Communications products on the same physical host is not supported. |
The supported co-resident configurations are described in these sections:
Cisco WebEx Meetings Server is deployed on one or more virtual machines on ESXi hosts. CPU and memory resources, and storage space, is consumed by Cisco WebEx Meetings Server and by ESXi (VMware component that enables virtualization on the physical Cisco UCS Server). Depending on your system size, vCenter and multiple virtual machines may run on the same Cisco UCS server.
Cisco WebEx Meetings Server uses "resource reservation" for its virtual machines to guarantee system scalability. Other VMware workloads do not take CPU and other resources away from the virtual machines. The minimum requirements for each system size includes enough resources to support:
The hardware requirements specified in the OVA file are the minimum requirements that are needed to deploy Cisco WebEx Meetings Server. These requirements do not include any CPU, memory, or storage requirements for VMware vCenter or ESXi.
The requirements for the Cisco UCS Servers, as listed in the following tables, include requirements for Cisco WebEx Meetings Server 1.x, VMware ESXi 5.0 and 5.1, and vCenter 5.0 and 5.1 (in supported co-residency configurations). Be sure to purchase hardware with the specifications defined in the following tables.
Caution |
Co-residency, other than the configurations listed in the following tables, are not supported. If you disregard our system requirements, your virtual machines may not be able to boot. The deployment of the virtual machines may stall from within the earliest product screens during the vCenter OVA deployment. |
This is a schematic diagram of a 50 user system. The diagram illustrates two versions of a 50 user deployment. If you plan to add an HA system, those virtual machines are shown as the "redundant" virtual machines. If you do not want HA, then only deploy the primary system.
The following table lists the minimum hardware requirements for the ESXi hosts (Cisco UCS servers) in your system. For general requirements, see General System Requirements.
For more information about the bandwidth requirements, see Bandwidth on Cisco WebEx Meetings Server Network Interfaces.
Note |
Because the resource requirements for ESXi 5.1 is greater than that for ESXi 5.0, Cisco requires additional CPU cores for a system deployed on vSphere ESXi 5.1. |
Note |
Co-residency with vCenter is supported with a 50 user system deployment as configured in the following table. |
Note |
IOPS numbers for storage are not available for this release. Use the speed for internal drives (last column) as a guidance. You can substitute these internal drives with SAN or SSD. |
Note |
For brevity, we use the acronym IRP for the Internet Reverse Proxy in the following table. |
Virtual Machines on ESXi Host (Cisco UCS Server) | CPU Cores | Memory (GB) | Ethernet Ports | DAS (Local)Hard Drive |
---|---|---|---|---|
Admin | 24 | 1 TB; 7200 RPM | ||
Admin and vCenter (co-resident) | 36 | 1 TB; 7200 RPM | ||
IRP | 12 | 300 GB; 7200 RPM | ||
Admin and IRP (co-resident) | 8 | 36 | 1 TB; 7200 RPM | |
Admin and IRP and vCenter (all co-resident) | 12 | 40 | 1 TB; 7200 RPM |
Note |
If you plan to use an HA system, purchase the same hardware requirements and quantities as the primary system. |
This section illustrates how much media the virtual machines use and is intended for those with expert knowledge of VMware. CPU resources are specified as vCPUs (cores) and MHz (CPU cycles). The VMware VMkernel uses MHz cycles to control CPU scheduling.
Memory resources are specified by maximum memory and reserved memory. Reserved memory is not shared with other virtual machines on the same physical Cisco UCS Server.
Disk resources (storage) are controlled in two separate areas. During the OVA build, the CentOS filesystem partition sizes determine the minimum disk size. Secondly, vCenter controls the maximum disk space available.
The numbers in this table do not include resources for VMware ESXi or vCenter. See Resources Consumed by Cisco WebEx Meetings Server and the ESXi Host.

If you attempt to deploy a virtual machine without the minimum number of vCPUs, then the OVA deployment of the virtual machine will fail. If you attempt to deploy a virtual machine without the minimum total MHz, then the virtual machine will not power on. |

The numbers in the table below represent the design capacity for the Cisco WebEx Meetings Server system. Operating the system at a capacity higher than these specifications can result in a degraded user experience and may result in system instability.
