The correct sequence of steps to create an FG (Fine Granularity) Storage Pool within a PowerFlex system is as follows:

Create a Protection Domain: This is the first step, where you define a logical grouping of storage resources that share the same protection policy and fault tolerance settings1.

Create a Storage Pool: After establishing a Protection Domain, you create a Storage Pool within it. This pool will contain the physical storage resources1.

Add the SDSs (Storage Data Servers): The next step is to add SDSs to the Storage Pool. SDSs are the servers that contribute storage capacity to the pool1.

Add the SSD (Solid-State Drive) devices to the Pool: Once the SDSs are added, you then add the SSD devices to the Storage Pool to provide the actual storage capacity1.

Create an Acceleration Pool: This step involves creating an Acceleration Pool, which is used for caching to enhance the performance of the storage system1.

Add the DAX (Direct Access) devices to the Pool: Finally, you add the DAX devices to the Acceleration Pool. DAX devices are typically high-speed storage devices like NVMe drives that serve as cache

The process of creating an FG Storage Pool in a PowerFlex system involves a series of steps that establish the necessary components and configurations for the storage environment. The sequence starts with the creation of a Protection Domain, which sets the stage for defining how storage will be protected and managed. Within this domain, a Storage Pool is created, which is essentially a collection of storage resources. The SDSs are then added to this pool, contributing their storage capacity to the overall system. SSD devices are included next to provide the actual storage space. An Acceleration Pool is created to improve performance through caching, and DAX devices are added to this pool to serve as the cache, completing the setup of an FG Storage Pool1.

This sequence ensures that the storage system is configured for optimal performance and data protection, following the guidelines and best practices outlined in the PowerFlex documentation1. It’s important to follow these steps in order to maintain the integrity and efficiency of the PowerFlex storage system.
