Enable IGMP snooping on the AHV hosts:

IGMP (Internet Group Management Protocol) snooping is a feature that listens to IGMP traffic between hosts and routers. By enabling IGMP snooping on the AHV (Acropolis Hypervisor) hosts, the switch can intelligently forward multicast traffic only to the ports that have requested it.

This reduces unnecessary multicast traffic on the network and prevents congestion by ensuring that multicast packets are only delivered to the appropriate endpoints.

References:Refer to the Nutanix documentation on network configuration and best practices for managing multicast traffic.

To enable inbound internet access to Virtual Servers in an NC2 cluster on AWS for the HTTPS protocol, the administrator should use an AWS Network Load Balancer (NLB).

Configure the NLB listener to listen on TCP port 443, which is the standard port for HTTPS traffic.

Create a target group in AWS, and register the servers (Virtual Servers in the NC2 cluster) as targets within this group.

Ensure the NLB is properly configured with an Elastic IP (EIP) if required, to provide a static IP address for the load balancer.

Verify that the security groups and network ACLs associated with the load balancer and the target group allow inbound traffic on port 443.

References:Refer to AWS documentation on Network Load Balancers and Nutanix NC2 on AWS integration guides for step-by-step instructions on setting up and configuring the necessary components for enabling HTTPS access.

To ensure that every NC2 on AWS cluster deployed allows full access from the on-premises CVM subnet efficiently, the administrator should create a custom AWS Network Security Group.

Use a key value oftag:nutanix:clusters:externalfor the security group, and set the inbound allow address to the on-premises subnet.

This approach leverages AWS tags to manage security group rules dynamically and ensures that the necessary access permissions are applied automatically to all clusters with the specified tag.

This method reduces the need for manual configuration of each cluster's security group, streamlining the process for a test/dev environment where clusters are frequently created and destroyed.

References:Refer to the AWS documentation on Network Security Groups and Nutanix documentation on best practices for securing NC2 clusters.

To add an AWS account to the NC2 console, an AWS IAM user needs to be configured with the appropriate permissions to manage the EC2 resources. The required permission for the IAM user includes full access to manage EC2 instances, volumes, and related resources.

AmazonEC2FullAccess:

This permission grants full access to all EC2 resources, including the ability to create, modify, and delete instances, volumes, security groups, and more.

Essential for NC2 operations to manage the lifecycle of EC2 instances and associated components within the AWS environment.

Why Not Other Permissions:

IAMFullAccess: Grants full access to IAM resources but not specifically needed for EC2 operations.

IAMReadOnlyAccess: Only provides read access to IAM resources, insufficient for managing EC2 instances.

AmazonEC2ReadOnlyAccess: Provides read-only access to EC2 resources, insufficient for creating or modifying instances and other resources.

AWS supports EC2 bare-metal instances in regions with at least 3 partitions. Partitions in AWS provide high availability and fault tolerance by distributing instances across different hardware to minimize the impact of hardware failures.

With the Nutanix AOS Pro licensing, several advanced features and add-on products become available. Specifically, in the AWS cluster deployment wizard, the following add-ons are available:

Files:

Nutanix Files provides a software-defined, scale-out file storage solution that simplifies the management and scaling of unstructured data.

Advanced Replication:

Advanced Replication features in Nutanix include synchronous and asynchronous replication capabilities, allowing for robust disaster recovery and data protection solutions.

DARE (Data-At-Rest Encryption):

DARE ensures that all data stored on Nutanix clusters is encrypted, providing a higher level of security for sensitive information.

These features are included in the AOS Pro licensing tier, offering enhanced data management, protection, and security capabilities.

To manually create an AWS VPC with Public access to Prism Element for testing purposes, the following components must be created:

VPC: A Virtual Private Cloud to provide an isolated network for the resources.

Delegated Subnets: Subnets within the VPC to segment the network and allocate IP ranges.

Route Tables: To define routing rules for the subnets to ensure proper traffic flow.

NAT Gateway: To enable instances in the private subnets to access the internet.

Internet Gateway: To allow direct internet access to instances in the public subnets.

Load Balancer: To distribute traffic across multiple instances for improved availability and redundancy.

References:Refer to the AWS documentation on VPC creation and Nutanix documentation on network setup for Prism Element access.

For a VM deployed in an NC2 cluster on AWS to be accessed by resources within the on-premises datacenter, the security group associated with the User VM (UVM) subnet must allow inbound traffic on the specific ports required by the application.

If the security group rules do not permit inbound traffic on these ports, the communication will fail, even if other network configurations are correct.

The administrator should ensure that the UVM Security Group includes rules to allow inbound traffic for the application's required ports, facilitating proper communication between the VM and on-premises resources.

References:Refer to the AWS documentation on security group configurations and Nutanix NC2 documentation for details on configuring network access and security group rules.

To manually hibernate an NC2 on AWS cluster, the administrator can use the following methods:

Select the cluster under NC2 console and Select Hibernate/Resume on the cluster sur page: Navigate to the specific cluster in the NC2 console and use the provided Hibernate/Resume option.

Log into NC2 console, find the cluster name and select Hibernate/Resume from the ellipses: Access the NC2 console, locate the cluster name, and select the Hibernate/Resume option from the ellipses (three dots) menu.

These options allow for the manual control of the cluster's hibernation state directly within the NC2 console interface.

Nutanix Support & Insights

The clusters that are to be protected must be registered with the same instance of Prism Central (Answer C):

For Cluster Protect to function correctly, all clusters intended for protection must be registered under the same Prism Central instance. This ensures consistent management and coordination of protection policies and operations across clusters.

The Cluster Protect feature requires AOS version 6.7 or higher (Answer D):

Cluster Protect is a feature that is available starting from AOS version 6.7. To utilize this feature, ensure that the Nutanix clusters are running this version or a newer one.
