Study Notes

Overview of AHV

AHV (Acropolis Hypervisor) is designed for security, automation, and future-readiness by default.
It is optimized for running applications effortlessly without added complexity.
Supports hybrid cloud environments, integrating with various public and private infrastructures.

Key Features of AHV

Acropolis Dynamic Scheduler (ADS): Monitors and optimizes infrastructure, managing VM migrations, ensuring resource availability, and enforcing administrative policies.
Initial VM Placement: Determines the best host for a new VM and defragments clusters to optimize resource allocation.
High Availability Guarantees: Ensures VMs are recoverable in case of host failures by relocating VMs to maintain availability.
Hotspot Mitigation: Detects and resolves CPU and storage hotspots across hosts dynamically.
Dynamic GPU Management: Allocates specific GPU resources to VMs based on demand.
Cost-Based Remediation: Plans VM movements considering operational costs.

Nutanix Move

A tool for seamless cross-hypervisor VM migration, allowing minimal downtime and risk.
Automates migration processes, reducing manual steps and potential errors.
Compatible with various virtualization platforms: VMware ESXi, Microsoft Hyper-V, and Nutanix AHV.
Supports flexible source infrastructures and provides 1-click migrations without the need for application changes.
Enables pre-seeding of data and testing prior to cutover to minimize operational disruptions.

Migration Support

Supports VM migrations from multiple platforms to AHV and Nutanix Cloud, including AWS and Azure.
Provides pathways to migrate from ESXi to AHV, ensuring smooth transitions as business needs evolve.

Traffic Mirroring

Enables mirroring of inbound, outbound, or bidirectional traffic from selected source ports to destination ports for enhanced security analysis.
Facilitates packet troubleshooting and compliance needs through effective traffic visibility.

Link Aggregation

Supports three configurations for load-balancing and link aggregation in Nutanix environments: Active-Active MAC, Active-Backup, and Active-Active LAG/LACP.
Recommended settings include simplicity and optimal performance configuration based on needs.
Active-Active configurations allow bandwidth aggregation across multiple links while maintaining ease of setup and minimal requirements for upstream switches.

VMware ESXi and Nutanix Integration

VMware ESXi can target Nutanix Cloud Clusters (NC2) on both AWS and Microsoft Azure.
VMware ESXi on Nutanix can also target Nutanix AHV.

Microsoft Hyper-V

Targets include Nutanix AHV, VMware ESXi on Nutanix, and NC2 on AWS.

AWS EC2

Supports integration with Nutanix AHV, VMware ESXi on Nutanix, and NC2 on AWS.

Microsoft Azure Cloud

Integrates with Nutanix AHV, VMware ESXi on Nutanix, and NC2 on Azure.

Nutanix AHV

Targets include Nutanix AHV, AWS EC2, Microsoft Azure Cloud, and NC2 on AWS/Azure.

NC2 (Nutanix Cloud Clusters)

Supports deployment on AWS and Azure, targeting Nutanix AHV and NC2 on Azure.

Migration Strategies

Common strategy includes starting with VMware ESXi and later migrating to AHV.
Migration to Nutanix AOS can either start with ESXi and later transition to AHV, using tools like Nutanix Move for convenience.

Nutanix Move Tool

Simplifies and optimizes migration with minimal downtime.
Allows logical grouping of VMs for replication, supporting both individual and batch migrations.

Application-Based Migration

Offers flexibility for transferring complex applications, recommended for database scenarios and servers like Active Directory.

Direct Migration from ESXi to AHV

Nutanix Move can facilitate direct transfer to Nutanix AOS and AHV without needing Nutanix infrastructure.

Networking Configurations

CVM Network Requirements: Standard configurations involve using eth0 for public traffic and eth1 for internal storage. Advanced setup permits additional interfaces for replication or disaster recovery.

AHV Bridge and Uplink Configuration

Virtual switches can be managed via Prism or command line, allowing configuration of load-balancing algorithms and network segmentation.
Typically, one virtual switch suffices for clusters, but additional switches can be created for specific needs.

Traffic Mirroring

Enables replication of network traffic from AHV host interfaces to VM vNICs for security and analysis.
Supports inbound, outbound, and bidirectional traffic mirroring to enhance troubleshooting and compliance.

AHV Host Link Aggregation

Supports multiple link aggregation modes, enabling optimal configuration for cluster performance.
Active-Active mode aggregates bandwidth across links, while Backup mode offers reliability by using multiple links with failover.

Cisco ACI Integration

ACI (Application Centric Infrastructure) from Cisco integrates with Nutanix, automating the creation of VLAN networks based on End Point Groups.
APIC (Application Policy Infrastructure Controller) manages infrastructure configuration, aligning architectural needs with physical networking components.

Summary Points

Integration with Cisco ACI enhances Nutanix's networking capabilities, ensuring dynamic and scalable configurations for cloud environments.
Future updates to ACI will continue to improve operational efficiency and simplify network management within Nutanix systems.
