Getting to Know Dell EMC PowerFlex v3.5.x

What is PowerFlex and how does it work?

PowerFlex is a software-only solution that uses existing servers' local drives and LAN to create a virtual SAN that has all the benefits of external storage. PowerFlex utilizes the existing local storage devices and turns them into shared block storage.

PowerFlex software components are installed on the application servers and communicate via a standard LAN to handle the application I/O requests sent to PowerFlex block volumes. An extremely efficient decentralized block I/O flow, combined with a distributed, sliced volume layout, results in a massively parallel I/O system that can scale up to thousands of nodes.
