    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.
    • 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.
    • 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.
    • 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.
