Page 17 of 34 ● For Virtual Machine Hardware (vmv or vmx), see Broadcom.com for Major/Minor/vmv compatibility. o Application versions will define the minimum compatible version. For example, UCM 15 requires a minimum vmv 17/vmx 15. o Newer vmv/vmx versions are compatible unless explicitly indicated otherwise. o Cisco only provides Application OVAs for the required minimum vmv; if the customer needs a newer vmv, deploy OVA with the old vmv, then upgrade the vmv. ● VMware VM Tools (vmtools) are not compatible with applications release 15. Open VM Tools (open-vmtools) are required and are provided with the application. VM Placement and Required Hardware Specifications Co-residency of Cisco core calling applications, other Cisco applications and 3rd party/customer- homegrown applications is allowed as indicated in VM Placement Rules. You can use QuoteCollab to save time, or follow the VM Placement Rules in the sections below. CPU/Processor Requirements General ● If Cisco Calling Appliance, the CPU vendor/architecture/model is selected by default in the appliance model (no changes are supported). For more details, see Install Guide of each appliance.

1. Cisco Unified Communications Manager and the IM and Presence Service
2. Cisco Expressway Installation Guide
3. Cisco Emergency Responder Administration Guide ● For Cisco General-purpose and 3rd-party General-purpose hardware, must follow: ◦ CPU vendor/architecture must be listed in the table below. Applications are not supported for unlisted vendors/architectures (for example, ARM is not supported, nor is the Intel Processor-D architecture). ◦ Within a vendor/architecture, the selected CPU model must follow these rules: ◦ Model range must be listed in the table below (for example, Intel 69xxP or AMD 9xx5). Applications are not supported on unlisted model ranges. Some applications support different model ranges for different scale points. ◦ Have a minimum Base Frequency defined by each application’s Installation Guide (which may vary by scale point). Applications are not supported on frequency-scaling technologies like Intel Turbo Boost or AMD Turbo Core / Core Performance Boost / Precision Boost. Applications are not supported on CPUs that use power management “throttling” features.
