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
VCS version X7.1. The minimum requirements for future VCS software releases may differ and you should
refer to the release notes or administrator guide to ensure that pre-requisites are met.

Recommended platform
The recommended hardware on which to run a VCS VM is:
n
Cisco UCS C200 – M2, UCS C210 – M2, or UCS B200 – M2 with:
l
Processor supporting AESNI feature
l
6GB of RAM per VM
l
132GB disc space per VM (for a 4GB virtual disc 1 and a 128GB virtual disc 2)
l
R2XX-LBBU (Raid disk battery backup to enable cache)
l
Four hard disks (450GB SAS 15K RPM 3.5in HDD/hot plug/C200 drive sled)
l
PCI card Intel Quad port GbE Controller (E1G44ETG1P20)
Ensure that:
n
VT is enabled in the BIOS before installing VMware ESXi
l
ESXi to be ESXi 4.1 or ESXi5.0 (Update 1)
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 VCS VM has been moved to the Automatic startup section
automatically with the system”, and that the VCS VM has been moved to the Automatic startup section
n
your UCS system is configured with RAID 5
Specifications-based system – minimum specification
If using a specifications-based system, the minimum requirements are:
n
VM Host operational and running ESXi 4.1
n
6GB of RAM per VCS VM
n
132GB disc space per VM (for a 4GB virtual disc 1 and a 128GB virtual disc 2)
n
2 Cores reserved per VCS VM; each core >= 2GHz processor
n
vCenter or vSphere operational
Note: ESXi 5.0 is currently not supported; during testing a problem was observed on a Host using ESXi 5.0
and a LSI MegaRAID card. We strongly recommend using ESXi 5.0 Update 1, where this issue has been
resolved.

Co-residency support
The VCS can co-reside with applications (any other VMs occupying same host) subject to the following
conditions:
conditions:
n
no oversubscription of CPU: 1:1 allocation of vCPU to physical cores must be used (2 cores required per
VCS VM)
