Spectrum Scale software is offered by IBM to meet large-scale file storage requirements.  Spectrum Scale uses GPFS installed on IBM Power8 servers with either captive storage or attached to all flash external or disk-based storage systems.  Spectrum Scale software may be used with other available storage systems and servers.  The clustered distributed file system GPFS allows multiple nodes in a configuration.  A global namespace for access to large numbers of files is a key feature.  Standard hardware and software are integrated to provide the systems and advanced features.

The IBM Spectrum Scale is also offered as ESS which integrates standard hardware and software elements to provide file storage over standard protocols.  The standard hardware includes IBM Power server systems with internal or external disks systems.  The software elements include the General Parallel File System and Spectrum Protect (Tivoli Storage Manager).  IBM ESS has been certified as a storage target for HortonWorks Data Platform.

Object access is supported with the incorporation of Swift open source software installed on GPFS nodes.  Objects are stored as files within GPFS.  The extended S3 API for Swift is added to support applications written for S3 and AWS.

IBM Spectrum Scale software can be installed on different servers and utilize multiple storage systems including IBM NVMe-based FlashSystem 9100.  Additionally, Spectrum Scale can be installed on AWS for customers that run or develop analytics software in the public cloud.
