Works together
How the Pure Storage FlashArray //E connects to servers, storage and the network: 1 way, with the parts and products on each path.
File storage (NFS and SMB)
Front-end ports face the clients; back-end ports (on scale-out systems) connect the nodes to each other and need their own switch pair.
