    Study Notes

    Replication Factor 2 (RF2)

    • RF2 refers to a data replication method ensuring that two copies of data are maintained across different nodes in a cluster for redundancy.
    • Network uplink ports are critical for connecting cluster-wide communication and provide the necessary bandwidth for data transfer between hosts.

    LCM Framework Bundle on Dark Site

    • The LCM Framework Bundle should be extracted to the "C:\Nutanix\packages" directory on a dark site web server to facilitate updates effectively.

    External Connections to Nutanix Storage

    • The Volume feature allows external connections through a specified IP address, enabling access to Nutanix storage resources.

    SQL Server Cluster Uptime Configuration

    • Deploy SQL Server VMs on separate hosts within an AHV cluster to ensure maximum uptime and utilize High Availability (HA) in the event of a host failure.

    Redfish Protocol and LCM Benefits

    • The primary benefit of the Redfish Protocol is its ability to provide a standard interface for managing hardware, streamlining the LCM (Lifecycle Management) processes.

    Manual VM In-Place Restore

    • To perform a manual in-place restore of a mission-critical VM, the administrator should use the "Data Protection" option in Prism Central.

    Uploading a Remote Disk File

    • Administrators can utilize the "Image Configuration" option to upload a remote disk file effectively.

    IP Address Assignment for VMs

    • DHCP (Dynamic Host Configuration Protocol) supports the automatic assignment of IP addresses to virtual machines (VMs).

    Upgrading the LCM Framework

    • To upgrade the LCM framework to the latest version, the administrator should access the relevant update option via the management interface, ensuring all prerequisites are met.
