Study Notes

Nutanix Move and Failover

Nutanix Move minimizes downtime during VM format conversions between hypervisors.
Enables migrations with a single VM or groups of VMs.
Third-party tools often have similar experiences to Nutanix Move, but may involve additional costs and a learning curve.

Cross-Hypervisor Disaster Recovery (CHDR)

CHDR supports both sites with all non-end-of-life (EOL) AOS versions.
Limitations include:
- No support for vSphere snapshots or delta disk files, risking VM loss during migration.
- Does not support VMs with attached volume groups or shared virtual disks.
- Requires manual reattachment of virtual groups (VGs) when migrating from AHV to ESXi.

VMware vSphere Fault Tolerance

VMware FT should not be enabled on VMs protected with CHDR.
If already enabled, it must be disabled to prevent failure or crash of services post-migration.

AHV Graphics and Compute Performance

AHV supports NVIDIA GRID technology, allowing multiple VMs to use the same physical GPU.
The virtual switch aggregates similar OVS bridges and uplinks across AHV nodes.

Networking in AHV

Bridges and ports facilitate connectivity between physical and virtual network interfaces.
Default configuration includes OVS bridge (br0) for VM network traffic and Linux bridge (virbr0) for management.

Network Controller in AOS

Network Controller is part of Flow Virtual Networking for VLAN and Overlay network deployments.
Managed at Prism Central (PC) level.

Port Types in AHV

Internal ports connect to default bridges, tap ports connect vNICs, and VXLAN ports support IP address management.
Bonded ports aggregate physical interfaces for fault tolerance and load balancing.

CVM Network Requirements

Default is using eth0 for public traffic and eth1 for internal storage.
Advanced settings may include dedicated VLANs and additional interfaces if required.

AHV Bridge and Uplink Configuration

Manage AHV bonds via Prism or command line, selecting load-balancing algorithms.
Virtual switches control network configuration in the AHV cluster.

Traffic Mirroring

Enables monitoring of inbound and outbound traffic on AHV hosts' interfaces.
Mirrored traffic can be used for security analysis and visibility.
Each host supports two SPAN sessions, with destination traffic needing to go to a VM on the same host.

AHV Host Link Aggregation

Three modes available for link aggregation:
- Active-Active (MAC): Simple setup, limited bandwidth due to one active link.
- Active-Active (Backup): More robust but requires additional configuration.
- Active-Active (LAG/LACP): Optimized for bandwidth aggregation across multiple links; recommended for performance.
