Multinode Cluster Hardware Specifications

Migration from the Stand-Alone Cisco Unified Communications Domain Manager 10.6(x) system to a 4 Unified Node/2 WebProxy Node cluster is supported. The resource requirements for each configuration are provided in Table 1.

Table 1 Virtual Machine Requirements
Node Type Quantity VM Level Memory1 CPU Disk Network
Unified >= 4 VMware 5.1 or later 8 GB 4vCPU @ 2 GHz 370 GB partitioned as follows:

  • 20 GB for OS

  • 50 GB for application

  • 50 GB for compressed backups

  • 250 GB for database

1 Gbit/s minimum
WebProxy >=2 VMware 5.1 or later 4 GB 2vCPU @ 2 GHz 70 GB partitioned as follows:

  • 20 GB for OS

  • 50 GB for application

1 Gbit/s minimum
1 For the 4 Unified Node/2 WebProxy node deployments where the total number of end users is expected to exceed 100,000, it is recommended that 16 GB of RAM be provisioned for each Unified node. The recommended memory allocation for the WebProxy nodes does not change.

The size of the database storage partition supports the maximum deployment size for the release. Further increase in the size of the partition is not required when new customers are on-boarded.

To set up the disk requirements, the disk should be set up on the VMware GUI Resources tab where a disk can be created. This task should be done after the OVA import but prior to the boot of the system.

The Database storage partition is sized at the initial installation to support the maximum deployment size for the release. Further increase in the size of the partition is not required as new customers are on-boarded.

For the disk requirements, the disk should be set up on the VMware GUI Resources tab where a disk can be created. Perform this task after the OVA import but prior to the boot of the system.
