Nutanix on HPE ® ProLiant ® 4. General Best Practices | 11 4. General Best Practices HPE ProLiant DX systems come from the HPE factory with AHV installed as the hypervisor. If the customer wants to use a different hypervisor or an earlier version of AHV, they can use the Nutanix Foundation provisioning tool. When using Foundation to image a cluster with VMware ESXi, use the HPE-customized ESXi ISO image that includes HPE-specific device drivers. Nutanix nodes use a whitelist of hypervisor ISOs based on the file hash, and this whitelist includes the custom HPE ESXi ISO. You can view the hypervisor whitelist under the Foundation downloads page on the Nutanix Support Portal. Refer to the Field Installation Guide for step-by-step instructions for installing ESXi on Nutanix. Follow the LCM workflows and best practices to determine and update the correct firmware and BIOS versions. From version 2.3.1 onward, LCM supports appliance firmware management for both HPE ProLiant DL servers and DX integrated systems. LCM automatically downloads the firmware bundle from www.nutanix.com (if reachable), or a local web server can host it on-site. HPE ProLiant DX integrated systems ship from the factory with the appropriate firmware and AOS software. Nutanix does not recommend using HPE tools such as SUM or OneView for firmware management and upgrades. As in any other Nutanix deployment, administrators should typically perform hypervisor, AOS, and firmware upgrades through the Nutanix Prism interface. There are some situations that may require SUM and OneView, such as when downgrading firmware to meet a corporate mandate or when applying an urgent security patch not covered in an existing SPP bundle. When performing physical server maintenance in such cases, ensure that you shut down no more than one node in a Nutanix cluster at a time. Because HPE tools, and not Nutanix tools, conduct host management operations, the process needs coordination between the hardware and software layers. Unlike Nutanix LCM, HPE tools (like SUM) are not cluster aware. 4.1. Common Networking Best Practices In all Nutanix deployments, the Controller Virtual Machine (CVM) and hypervisor management network adapters must share the same network broadcast domain and subnet. You must have connectivity in the same layer 3 network between all CVMs and hypervisors in the same Nutanix cluster. The host management adapters do not have to be in this same subnet but placing them in the same network simplifies network address design. Storage Traffic Between CVMs in ESXi In ESXi hosts, you can create a port group named CVM Network that prefers vmnic0 as active and vmnic1 as standby to ensure minimal latency between Nutanix CVMs. Connect vmnic0 in
