FLEXIBLE, MULTI-PROTOCOL ACCESS

The PanFS storage operating system supports simultaneous multiple protocol access, suitable for a diversity of customers, applications and types of users.

  • DirectFlow®: The parallel data access protocol designed by Panasas
    • For Linux clients
    • For Mac clients
  • NFS v3: for Linux, Unix and Mac clients
  • SMB v2: for Microsoft Windows clients

DirectFlow

DirectFlow avoids traditional protocol I/O bottlenecks by allowing Linux compute clients to access the entire Panasas storage cluster directly and in parallel. This results in higher performance than what can be achieved with industry-standard protocols such as NFS and SMB, and avoids the load balancing and congestion side effects of these client protocols when addressing clustered file systems.

DirectFlow is a sophisticated file system software that runs inside each compute client, establishing a parallel I/O relationship from the client to the PanFS storage operating system for every file read/write. DirectFlow also performs client-side data parity calculations when writing to Panasas storage, relieving this burden from storage to unleash greater performance benefits.

When you double the performance of client applications accessing scale-out NAS you double the productivity of all users. Using DirectFlow, Panasas customers have re-rendered entire movies in record time, reduced the cost of sequencing a human genome, and designed breakthrough products by running twice as many engineering simulations more quickly than ever before.

DirectFlow® for Linux®
DirectFlow provides unmatched performance for Linux clusters of all sizes and is ideal for the high performance Linux clusters deployed in nearly 500 technical computing environments such as manufacturing, life sciences, media & entertainment, education, government, energy, and the public sector. Deployed across a large variety of Linux-based computing environments, the DirectFlow protocol has proven success at delivering more than 10x the performance of workloads using traditional I/O protocols.
