Study Notes

Key AHV Features

AHV includes VM High Availability (HA) to ensure virtual machines remain operational during hardware or software failures by automatically restarting them on healthy nodes.
Fast VM Migrations are facilitated by micro-stunning and Cross Cluster Live Migration (CCLM), allowing uninterrupted service during VM transfers, including cross-hypervisor migrations from ESXi to AHV.
Acropolis Dynamic Scheduling (ADS) monitors for compute and storage contention, creating migration plans to prevent hotspots and optimize VM placement for efficiency.
Intelligent VM Placement adjusts workload distribution across clusters for optimal performance and utilizes Automatic Cluster Selection in AOS 6.8 for intelligent workload placement.
Comprehensive Security features include one-click STIG applications and automated compliance with self-healing capabilities to enhance virtualization security.

Data Locality in AOS Storage

Reduces network congestion, optimizing access speed and performance by keeping data close to where it is needed.

Key Resiliency Features of AOS Storage

Automatic self-healing addresses component failures, improving system reliability.
Independent scaling allows separate expansion of compute and storage resources for better resource management.
Granular and efficient snapshots facilitate quick data recovery and backup without heavy impact on performance.

Storage Optimization Techniques in AOS Storage

Erasure coding offers data protection while minimizing storage overhead.
Compression reduces data size, enhancing I/O performance and conserving storage space.
Deduplication eliminates duplicate copies of data, maximizing storage efficiency.

AHV's Key Capabilities

VM High Availability ensures continuous VM operation.
Fast VM Live Migrations enhance operational resilience during VM transfers.
Software-defined Networking enables flexible and dynamic network management.

Acropolis Dynamic Scheduling (ADS)

Optimizes VM placement based on workload demand and resource availability, enhancing cluster performance.

Deployment Options for Prism Central Instance

Available as a Single VM or up to three VMs, providing scalability based on operational needs.

Nutanix Asynchronous Replication Advantage

Allows for flexible replication topologies, offering resilience and efficiency without strict latency requirements.

Flow Network Security Capabilities

Allows independent scaling of compute or storage resources, optimizing resource allocation based on application requirements.
Compute-only (CO) nodes dedicate resources exclusively for computing tasks, while storage-only (SO) nodes expand storage capacity without requiring additional hypervisor licenses.

Storage Policies in AOS

Easily created and attached to VMs, allowing dynamic management of storage attributes like replication factor, encryption, compression, and QoS.
A single storage policy can manage several entities, enhancing flexibility and efficiency in storage management.

Storage Optimizations in AOS Storage

Incorporates data efficiency technologies including compression for space savings and performance enhancement, deduplication to eliminate redundancy, and erasure coding for data protection.
