Study Notes
Getting Started With NC2 on AWS
- To get started with NC2 on AWS, ensure you are registered on the My Nutanix portal. Ensure you understand NC2 Licensing and Billing. Release Notes and Software Compatibility documents provide further details.
- After creating an AWS cluster, set up the network and security infrastructure for your virtual machines (VMs). This includes configuring User VM Network Management and Network Security using AWS Security Groups.
- Prior knowledge of the Nutanix stack and AWS services such as EC2, VPC, and CloudFormation is recommended for effective deployments.
- NC2 on AWS requires an AWS account with CreateRole access.
- Use a CloudFormation script to create IAM roles for NC2 on AWS. Necessary permissions include IAMFullAccess and AWSCloudFormationFullAccess.
- These roles are essential for communication with AWS APIs and for managing your bare-metal instances, using the Nutanix-Clusters-High-Nc2-Cluster-Role-Prod and Nutanix-Clusters-High-Nc2-Orchestrator-Role-Prod roles.
- You can review the related CloudFormation script from the provided URL.
- Review available vCPU limits for different instance types supported by AWS.
- The CloudFormation template was updated on September 18, 2024. The template needs to be run to ensure consistency with updated permissions
- AWS supports various instance types. Ensure the selected instance type is supported by the desired availability zone.
- NC2 utilizes several ports and protocols for communication. Refer to the Ports and Endpoints Requirements document for details on inbound and outbound communication.
- NC2 supports EC2 bare-metal instances in various AWS regions. Refer to the Table 1. EC2 Bare-metal Instance Details and Table 2. AWS Clusters – Available Regions and Supported Bare-metal Types for specific details.
- NC2 supports different AWS tenancy models, including a default option for bare-metal instances that can migrate across hosts during operation, and a dedicated host option for instances that remain on the same physical host.
Network Requirements
- Configure network connectivity between on-premises datacenters and AWS VPC using either VPN or Direct Connect.
- Explore AWS Site-to-Site VPN and AWS Direct Connect for respective information on setup and configuration.
- Allow outbound internet access for NC2 console to provision and orchestrate Nutanix clusters in AWS.
- Detail VPC (Virtual Private Cloud) configuration, encompassing options for new VPC creation or usage of existing VPCs.
- Address DNS resolution to avoid failure to resolve necessary FQDNs in cases of AWS Directory Service deployments
- Use the default AWS DNS server, or a custom DNS server, along with associated DNS attributes for NC2 on AWS deployments
- Ensure the proper configuration of the default AWS DNS server for resolution of S3 and EC2 private endpoints
CIDR Requirements
- Define specific CIDR ranges for VPCs, subnets, and other network components (e.g., Private management subnet, Public subnet, UVM subnets).
- If using NC2 with Flow Virtual Networking, adhere to specific CIDR requirements for Prism Central and Flow Virtual Networking subnets.
IMDS Requirements
- NC2 on AWS supports accessing instance metadata using the Instance Metadata Service Versions 1(IMDSv1) and 2 (IMDSv2).
My Nutanix Account Requirements
- Configure a My Nutanix account to access the NC2 console.
- Upon account creation, a default workspace is created with an Account Admin role, which is crucial for NC2 subscription and access to the Admin Center and Billing Center.
- Create a new workspace to use for NC2, or join an invited one, with the Account Admin role required for subscription purposes.
Cluster Protection Requirements
- Meet additional requirements if using the Cluster Protect feature. Refer to the Prerequisites document.
Ports and Endpoints Requirements
- Detailed information on specific ports and protocols used for communication by NC2, including outbound and inbound communication and related Microservices Infrastructure details.
Supported Storage Volumes
- NC2 utilizes NVMe solid state drives for local storage.
- EBS volumes (encrypted gp3) are used for boot volumes for AHV and CVM instances
- AOS 6.8 and later versions support additional EBS volume attachment. Scaling storage independently from compute capacity is supported.
- EBS volume capacity can be up to 80% of the total capacity
- Supported volumes may depend on metal instance type for NC2 running on AWS.
- EBS Storage is not supported with heterogeneous clusters
- EBS storage can only increase capacity after the deployment.
Instance Storage
- Provide a tabular format listing various metal types and their associated storage and memory details according to specific regions.
Limitations
- Maximum number of nodes in a cluster is 28.
- Single-node clusters are not recommended in production environments.
- Other limitations: such as two-node clusters and IP address limits per node are part of the supported instance limitations on different platforms and environments
- Other limitations: AWS-specific limitations such as dedicated host tenancy and partition placement are important considerations.
nCLI and API Operations
- Provide details on disabled or changed nCLI and API operations in an AWS deployment.
Creating My Nutanix Account
- Steps for creating a My Nutanix account and how to navigate the account creation process, including password policies and email requirements.
