IBM Spectrum Scale is a multi-protocol, high-performance, highly available, clustered file system and associated management software. IBM Spectrum Scale can scale in several dimensions, including performance (bandwidth and IOPS), capacity, and number of nodes (instances) that can mount the file system. IBM Spectrum Scale addresses the capacity and performance requirements to support modern scale-out applications such as AI/ML/DL with multi-cloud support. The latest version of IBM Spectrum Scale delivers an unprecedented, world-class level of performance for file storage. The improvements were driven by the demands of providing the storage software for the world’s most powerful supercomputer, the US Department of Energy Summit system at the Oak Ridge National Laboratory. Those same innovations are now available to commercial customers, and include major improvements across the product, including performance, space efficiency, improved installation and setup, more powerful GUI and improved security to help organizations address new regulations such as GDPR.
