The IBM Elastic Storage Server (ESS) system based on IBM Spectrum Scale software is offered by IBM to meet large-scale file storage requirements. ESS uses IBM Spectrum Scale installed on either AMD Servers in the case of the ESS 3200/3500 or IBM Power servers with either captive storage or attached to all flash external or disk-based storage systems for earlier models and the 5000 models. Spectrum Scale software may be used with other available storage systems and servers. Two server-based systems make up an ESS node pair and the clustered distributed file system GPFS allows multiple node pairs 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 ESS system integrates standard hardware and software elements to provide file storage over standard protocols. The standard hardware includes AMD or IBM Power server systems with internal or external storage. The software elements include Spectrum Scale (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.
