HPC Storage Performance White Paper

Cray ClusterStor NXD Performance Comparison

Is your storage solution ready for the future?

New areas of computing, like artificial intelligence, are changing high-performance computing (HPC) storage needs. Traditional parallel HDD-based file systems are capable of high sustained throughput and are good at large streaming reads and writes — but with an increasing number of small reads and writes, random seeks and unaligned writes, parallel file systems can be brought to their knees.

In this white paper, Cray’s Torben Kling Petersen details storage options for high-performance computing and discusses why flash acceleration — and Cray’s ClusterStor™ NXD software stack — can be a smart choice for your HPC storage requirements.

Learn about the benefits and constraints of various storage architectures:

Traditional
HDD-based storage

All-flash
storage solutions

A hybrid HPC
storage approach

In addition, the white paper covers:

  • The NXD I/O manager and how NXD delivers high IOPS without affecting streaming throughput
  • NXD I/O tools that allow the user to get a clear picture of HPC application throughput and identify potential performance issues
  • The difference between the NXD software stack and other flash caching solutions
