Page 4 of 34 Introduction to Supported Virtualization Environments Cisco only supports on-premises calling applications in the following virtualization environments when configured in accordance with this document. This document covers common virtualization baseline support. Note: For application-specific details, including any application-specific differences from this document, see the Install Guide of each application. VMware vSphere ESXi VMware ESXi (formerly named ESXi, now renamed back to ESX in version 9.0) is an enterprise-class, type- 1 hypervisor developed by VMware and Broadcom. As a Type 1 hypervisor, ESXi runs directly on bare- metal hardware without requiring a host operating system, providing direct access to hardware resources for enhanced performance and efficiency. Cisco on-premises applications are supported on VMware vSphere ESXi running on a broad spectrum of Cisco Calling Appliances, Cisco General-purpose Compute/Storage, and third-party General-purpose Compute/Storage. For more information on vSphere ESXi, see Broadcom.com. For more information on Cisco on-premises calling applications support on ESXi 8.0, see Virtualization Requirements for VMware vSphere ESXi. For more information on Cisco on-premises calling applications' support of vSphere ESXi 7.0 and older, see Cisco Collaboration Virtualization. Nutanix AHV Nutanix is a hyperconverged infrastructure (HCI) platform that integrates compute, storage, and networking into a single, software-defined system, providing a robust foundation for hybrid cloud deployments. Acropolis Hypervisor (AHV) is a hypervisor from Nutanix that runs alongside Acropolis OS (AOS) hyperconvergence software and Prism Central (PC), a web-based, centralized management software. These products are all part of Nutanix Cloud Infrastructure (NCI) or Nutanix Cloud Platform (NCP) portfolios. Cisco Compute Hyperconverged with Nutanix (CCHN) is a joint solution that runs Nutanix software on Cisco hardware, with joint support from both companies. Cisco on-premises applications are supported on Nutanix AHV, AOS, and PC with CCHN hardware. For more information on Nutanix software, see the Nutanix Home page. For more information on CCHN hardware, see Cisco Compute Hyperconverged with Nutanix For more information on Cisco on-premises calling applications support on Cisco Compute Hyperconverged with Nutanix, see Virtualization Requirements for Nutanix AHV.
