Cisco Cisco Expressway Installation Guide
Installing a VM
The sections below list the recommended platform and specifications-based system requirements, and
describe the VM installation process. The requirements outlined below refer to the minimum requirements for
Expressway version X8.2. The minimum requirements for future Expressway software releases may differ
and you should refer to the release notes or administrator guide to ensure that pre-requisites are met.

Co-residency support
The Expressway can co-reside with applications (any other VMs occupying same host) subject to the
following conditions:
following conditions:
n
no oversubscription of CPU: 1:1 allocation of vCPU to physical cores must be used
n
no oversubscription of RAM: 1:1 allocation of vRAM to physical memory
n
sharing disk storage subsystem is supported subject to correct performance (latency, bandwidth)
