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 X8.6. 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.

list of supported UCS Tested Reference Configurations and specs-based supported platforms.
Ensure that:
n
VT is enabled in the BIOS before installing VMware ESXi
n
the VM host “Virtual Machine Startup/Shutdown” is configured to “Allow Virtual machines to start and stop
automatically with the system”, and that the VM Expressway has been moved to the Automatic startup
section

When using vSphere, configuration of the network properties must be done through the console.
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
no oversubscription of NIC: The Expressway handles large volumes of data, much of which is for real-
time communications, and it needs dedicated access to all the bandwidth specified for its interfaces.
For example, you should not assume that four co-resident small Expressway VMs can handle the
expected load if there is only a 1 Gbps physical interface on the host. In this example, none of the VMs
meet the required minimum specification.

Note: The CPU reservation requirement excludes provision for the host's hypervisor. You should specify
your host CPU resources to accommodate the hypervisor and still be able to dedicate the CPU reservation
requirement to all co-resident Expressway VMs.
