Open vSwitch (OVS) Open vSwitch, or OVS, in short is an open source software switch. It is installed and run in the Linux kernel. It mimics a Layer 2 switch. In other words, it learns MAC addresses and maintains a MAC address table. It makes forwarding decisions based on these MAC addresses. It has virtual…

The network visualization page in Prism makes use of SNMP and LLDP to find info about the connected top of rack switch. SNMP is used to get switch information like the name, ports, and port statistics. LLDP is used by the AHV hosts to find out which Nutanix node is plugged into which switch port….
Data Protection Strategy The below image is a representation of the capabilities that the Nutanix solution offers across the entire data protection spectrum. Nutanix offers a natively integrated solution for data protection and continuous availability at VM granularity. It gives administrators an affordable range of options to meet the recovery point objectives (RPO) and recovery…
Synchronous Replication is a feature where data is synchronously replicated between two sites in metro availability configuration. In an event of a disaster on any one site, real-time data is available on the other site. The protection domain can be configured for metro availability or for synchronous replication depending on the following: Metro availability: The…
General Requirements and Limitations of Self Service Restore Set disk.enableUUID=true in the .vmx file for the VMs on ESXi. Guest VM must have Nutanix snapshots configured via a protection domain. Self service restore is not supported for the snapshots that you take from the VM table view. vStore protection domains are not supported. Volume groups…
What is Nutanix Guest Tools? As a recap, let’s revisit what is included in the Nutanix Guest Tools (NGT) Bundle: Nutanix Guest Agent (NGA) Service: This provides CVM-to-VM communication. File Level Restore (FLR) CLI: Exactly what it sounds like. This allows users to recover files without the need of an administrator. Nutanix VM Mobility Drivers:…
Memory and CPU are hot-pluggable on supported guest VMs running on AHV while the VM is powered on. Perform the following procedure to hot plug the memory AHV VMs: acli vm.update <vm_name> memory=<new_memory_size> Replace vm_name with the name of the VM and new_memory_size with the memory size. And to hot plug CPU: acli vm.update <vm_name>…
