Supported Source Environments You can migrate VMs from the following source hypervisors to AHV: VMware ESXi Microsoft Hyper-V Unified Extensible Firmware Interface (UEFI) Support Information In the current AOS and AHV releases, the UEFI implementation is limited. The following table describes the level of support available for various usage scenarios: Scenario Support Level Generation 2…
A storage container is a defined subset of available storage within a storage pool. Storage Containers allow you to apply rules or transformations such as compression to a data set. Logical segmentation of SP containing groups of VM’s/files (vDisks). Typically have 1:1 mapping with datastore VMware Storage presented via NFS (default) or iSCSI AHV Storage…
Active-backup The Active-Backup bond mode is the simplest, easily allowing connections to multiple upstream switches without any additional switch configuration. The downside is that traffic from all VMs use only the single active link within the bond. All backup links remain unused. In a system with dual 10 gigabit Ethernet adapters, the maximum throughput of…
The default AHV configuration includes an OVS bridge called br0 and a native Linux bridge called virbr0. The virbr0 Linux bridge carries management and storage communication between the CVM and AHV host. All other storage, host, and VM network traffic flows through the br0 OVS bridge. The AHV host, VMs, and physical interfaces use ports…
Unsegmented Network In the default, unsegmented network in a Nutanix cluster, the Controller VM has two virtual network interfaces—eth0 and eth1. Interface eth0 is connected to the built-in external virtual switch, which is in turn connected to the external network through a bond or NIC team that contains the host’s physical uplinks. Interface eth1 is…
No backplane for internode communication All I/O’s handled by hypervisor on private network I/O is forwarded from hypervisor to CVM CVM replicates with other nodes with external IP over public 10GB network Read requests are served locally Typically, the only traffic on the 10G public is replication Occasionally CVM will forward requests in event CVM…
A virtual network can have an IPv4 configuration, but it is not required. A virtual network with an IPv4 configuration is a managed network; one without an IPv4 configuration is an unmanaged network. A VLAN can have at most one managed network defined. If a virtual network is managed, every NIC must be assigned an IPv4 address…
I have always been a fan of leveraging community resources when studying for certification exams. The VCAP study guides here, and here were invaluable when I was studying for those exams. When I began preparing for the Nutanix NCP, I was a little bummed out when I couldn’t find any community resources like these. I…
