Page 13 of 34 VM Placement Derive server/appliance count using applications’ VM Placement and co-residency rules vs. your needs for sites and redundant hardware. You can use QuoteCollab to save time. For VMware vSphere ESXi and Nutanix AHV, unless otherwise indicated in application-specific documentation, co-residency of supported Cisco core calling applications + other Cisco applications + 3rd-party/customer-homegrown applications is allowed if the underlying virtualization environment allows. For more information, see Virtualization Requirements for VMware vSphere ESXi and Virtualization Requirements for Cisco NFVIS-for-UC. For Cisco NFVIS-for-UC, only Cisco core calling applications are supported. Other Cisco applications are not supported. 3rdparty/customer-homegrown applications are not supported. For more information, see Virtualization Requirements for Cisco NFVIS-for-UC. All applications sharing hardware must align with the requirements in this document. To diagnose or resolve an issue with a Cisco on-premises calling application, Cisco TAC may ask that workloads be powered down or moved to another server (for example, if a 3rd-party workload is a “noisy neighbor” causing symptoms in Cisco Unified CM). VM Placement rules for each hardware component are in the next section.
