APEX File Storage for AWS Getting Started Guide

APEX File Storage for AWS architecture overview

APEX File Storage for AWS allows you to create and deploy PowerScaleOneFS clusters through the resources available with Amazon Elastic Compute Cloud (Amazon EC2) on the Amazon Web Services (AWS) Cloud infrastructure.

APEX File Storage for AWS is a software-defined and customer-managed scale-out storage solution running on AWS cloud infrastructure. It brings the Dell Technologies PowerScaleOneFS distributed file system into the public cloud to provide users with the same management experience as an on-premises PowerScale cluster. You can run OneFS on multiple EC2 instances backed by EBS volumes, and then form a OneFS cluster using the EC2 instances virtual nodes.

In general, cluster performance is correlated to your cluster size. The more cluster nodes (up to a maximum of six), the higher the throughput and IOPS. Therefore, before creating your cluster in AWS, consider the capacity of storage and the number of nodes that you need for your business workflow.

The following diagram shows the architecture of APEX File Storage for AWS.

Resource Description
Availability zone APEX File Storage for AWS is designed to run in a single availability zone to obtain the best performance.
VPC APEX File Storage for AWS requires an AWS VPC to provide network connectivity.
OneFS cluster internal subnet Cluster nodes communicate with each other through the internal subnet. The internal subnet must be isolated from instances that are not in the cluster . Therefore, a dedicated subnet is required for the internal network interfaces of cluster nodes and that do not share the internal subnets with other EC2 instances.
OneFS cluster external subnet Cluster nodes communicate with clients via through the external subnet by using different protocols, such as NFS, SMB, and S3.
OneFS cluster internal network interfaces Cluster nodes network interfaces are located in the internal subnets.
OneFS cluster external network interfaces Cluster nodes network interfaces are located in the external subnets.
OneFS cluster internal security group Security group applies to the cluster internal network interfaces, which allows traffic between the internal network interfaces of cluster nodes.
OneFS cluster external security group Security group applies to the cluster external network interfaces, which allows specific ingress traffic from clients.
EC2 instance nodes Cluster nodes which run the OneFS file system backed by EBS volumes.
