DirectFlow Client Software

Panasas DirectFlow Protocol for Fast Parallel I/O

The Panasas® DirectFlow® proprietary protocol runs inside each compute client and establishes a parallel input/output (I/O) relationship from the client to the Panasas PanFS® storage operating environment for file read/write.

This structure creates higher performance than industry-standard protocols such as Network File System (NFS) and Server Message Block (SMB), avoiding the load-balancing and congestion side effects of these protocols when addressing clustered file systems.

DirectFlow for Linux


Panasas DirectFlow for Linux provides unmatched performance for Linux clusters of all sizes. It is ideal for the high-performance Linux clusters deployed in nearly 500 technical computing environments such as manufacturing, life sciences, media and entertainment, education, government, energy, and the public sector.

In a large variety of Linux-based computing environments, the DirectFlow protocol delivers more than 10 times the performance increases over workloads using traditional I/O protocols.
