This section describes the Instance Store based option of deployment. This example uses a two-layer PowerFlex architecture that is deployed in the US East (North Virginia) region with three AZs. The Dell APEX Block Storage for AWS is deployed using three i3en.12xlarge Amazon EC2 instances with four x 7.5 TB instance store (native attached NVMe SSD drives) on each EC2 instance. Each instance uses Red Hat Enterprise Linux 8.4-based AMI. The three PowerFlex SDS nodes are configured across AZs in a single protection domain.
A single pool is created using all the storage devices in a protection domain. The PowerFlex SDC service is installed on the Amazon EC2 c5n.18xlarge instance type running on different AZs. The MongoDB databases are running on SDC instances in a private subnet.
The following figure shows the placement of Amazon EC2 instances spanning across three AZs and the instance type that is used for this deployment:
