Throughout your deployment, you are using the AWS Management Console and the AWS CLI to instantiate the required AWS cloud resources on Amazon EC2. Adding nodes, replacing failed nodes and drives requires working with both
OneFS and AWS.
An administrator creates the following Amazon EC2 instances, policies, roles, groups, nodes (VMs), disks, network interfaces, and clusters using the
AWS Management Console, the
AWS CLI, and the
OneFS CLI:
IAM policies, roles, and instance profiles
OneFS nodes require an instance profile to be attached.
The
ec2:AssignPrivateIpAddresses permission must be assigned to the cluster network interfaces at runtime so that they can interact with the AWS APIs.
Creating the IAM policy, role, and instance profile for a
OneFS cluster is one-time work for the same AWS account. These resources are reusable when deploying additional
OneFS clusters.
Spread placement groups
A node VM spread placement group is required to ensure that nodes are placed on distinct hardware to ensure high availability.
A placement group for the cluster is defined at the time of deployment.
Virtual machine (VM) host isolation is obtained by placing each VM in the cluster in a different spread group. Each spread group maps to a different rack in the data center.
EC2 allows a maximum of seven running instances per availability zone.
Create a security group for the
OneFS cluster front-end network (external security group) to allow specific ingress traffic from clients.
Create a security group for the
OneFS cluster back-end network (internal security group) to allow all traffic between cluster nodes internal network interfaces only.
Network interfaces
Create network interfaces for the
OneFS cluster front-end network (external interfaces).
Create network interfaces for the
OneFS cluster back-end network (internal interfaces).
EC2 instance user data
OneFS requires user data in a JSON format file that is provided in the bits for your package. The JSON file provides new instances running
OneFS with the information that is needed to create a
PowerScale cluster.
EC2 instance types: m5dn family
Sizes: 8xlarge through 24xlarge
