Notes on 2500 Agents VM Configuration

(top)

Cisco Enterprise Chat and Email configuration for deployments that support up to 2500 concurrent email or chat agents. Deployment requires 6 VMs as shown below:

VM # of VMs to deploy of each Component

VM 1 - File Server 1

VM 2 - DB Server 1

VM 3 - Services Server 1

VM 4 - Messaging Server 1

VM 5 - Application Server (833 concurrent email or chat agents per server) 3

VM 6 - Web Server (833 concurrent email or chat agents per server) 3

IOPS and Storage System Performance Requirements

(top)

Enterprise Chat and Email follows UC storage system design requirements. For more information, refer to UC Virtualization Storage System Design Requirements.

For information about TRC versus specs-based support for storage systems, refer to UC Virtualization Supported Hardware.

All Enterprise Chat and Email VM vDisks must be deployed Thick Provisioned, Lazy, or Eager Zeroed. Thin Provisioned vDisks are not supported.

Storage Area Networks and Specs-based policy storage solutions must be able to handle the following Enterprise Chat and Email application disk I/O characteristics. Tested Reference Configurations (TRC) for Cisco UCS C-Series servers do not need to apply these requirements against their Direct Attached Storage Arrays (DAS).
