Singlewire recommends that you deploy InformaCast on any hardware supported by VMware ESXi because it provides the lowest overhead of the VMware products1. VMware ESXi is available free of charge from vmware.com. If VMware is new to you, you may find these resources useful:
If you are unsure whether your server hardware supports VMware, check the VMware ESXi compatibility list.

- 4Gb of memory
A dedicated virtual CPU (vCPU)—the InformaCast operating system and application are 32-bit, and may run on 32- or 64-bit CPUs.
The CPU speed requirements are defined as follows:
- For IP phone deployments, InformaCast does not have a minimum CPU speed requirement; regardless of the number of phones, InformaCast will scale to meet the need. In general, faster CPU means faster phone activation time.
- For computers running the InformaCast Desktop Notifier or IP speakers in excess of 1,000 endpoints, contact Singlewire for the most current recommendations.
- A single virtual NIC configured for bridging, not NAT; InformaCast will not work through NAT’d network connections
- 80Gb disk, which can be either local disk or SAN-attached disk (the SAN may be of any type supported by VMware)
As a virtual machine (VM), InformaCast may be run co-resident with other Cisco UC virtual machines on a VMware ESX host2, as long as you don’t modify the InformaCast OVA configuration or oversubscribe the host CPU or memory. It is possible to run more virtual machines than the VMware host physically supports (i.e. oversubscription), but this will adversely affect audio quality and phone activation performance.
In order to avoid oversubscribing your VMware host, please make sure the following is true:
- The sum of all vCPUs does not exceed the number of cores on the VMware host
- The sum of memory needed by all VMs does not exceed the amount of physical RAM on the VMware host
- The InformaCast VM is run in thick disk mode
1 Other VMware products (i.e. VMware Player, VMware Workstation, or VMware Server) will work for lab or demonstration purposes.
