Module

Requirements Notes

Host Server & Processors
  • Cisco UCS "C-series" rack server. Equivalent B-series blade may be substituted.
  • Must support "AES-NI" instruction set.
  • 2.4 GHz processor clock speed or faster

Network interfaces
  • Minimum 1 physical NIC for non-redundant configuration. See the 50-user page below, for special requirements where the Internet Reverse Proxy (IRP) and Admin virtual machine are sharing a host.
  • Redundant configurations must have all NIC interfaces duplicated ("teamed" or "bonded") and connected to independent switching fabric.
  • Recommend an additional NIC for VMware management network (optional).

Internal (DAS) Storage for ESXi hosts where internal virtual machines are deployed
  • Minimum of 4 drives in a RAID-10 or RAID-5 configuration
  • Minimum of 1 TB usable storage (For example, 4 x 600 GB RAID-10)
  • Optional 2nd array for ESXi

Internal (DAS) storage for ESXi hosts where IRP virtual machines are deployed
  • Minimum of 2 drives in a RAID-1 configuration
  • Minimum of 300 GB usable storage (For example, 2 x 300 GB drives make 300 GB)
  • May use the same configurations as for the internal virtual machines

SAN Storage
  • May be used as a substitute for DAS.
  • Recommended only for deployments where the support staff has experience monitoring and tuning SAN performance.
  • Fiber Channel (FC) or Fiber Channel over 10 Gb Ethernet (FCoE) only.
  • Performance requirements are the same as for DAS.

To learn about SAN space requirements, refer to the section for your specific system in this document.

Hypervisor
  • vSphere Enterprise Plus license for 800 and 2000 user systems. vSphere Standard license for 50 and 250 user systems.
  • vSphere versions 5.0 or 5.0 Update 1.
  • One VMware license per processor socket.
  • vCenter Server 5.0 or 5.0 Update 1.
  • vCenter may be co-resident with the product providing the processor and memory requirements are added to the application requirements. Co-resident configurations are supported for 50-user and 250-user systems.

50 User System

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 recommendations for your system.

Virtual Machines on Host (Physical Server) CPU Cores Memory (GB) Ethernet Ports Hard Drive
Admin 4 26
  • 2 for the Admin virtual machine (including 1 for redundancy)
  • 1 recommended for ESXi management network
  • Minimum 1 Gbps speed
1 TB; 7200 RPM
Admin and vCenter (co-resident) 8 36
  • 2 for the Admin virtual machine (including 1 for redundancy)
  • 1 for vCenter

System Capacity Matrix

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. Cisco reserves the right to enforce capacity limits at these levels.
