The IBM Elastic Storage Server or ESS storage system is a high-end, highly scalable NAS system that is targeted at very large terabyte and petabytes environments. Typical large scale environments include data analytics with Hadoop Media & Entertainment, geo-sciences, life sciences, backup and archive. The ESSS system represents an integration of elements by IBM into a multi-featured NAS system.
In the integration to create the ESS system, IBM has used their servers, the General Parallel File System, storage from their OEM suppliers, and the Linux operating system as the base system and Tivoli Storage Manager (TSM) integrated for additional advanced features.
The IBM ESS system is the offered by IBM to meet large-scale file storage requirements. The key capability with ESS is the very large scaling of up to 16,384 nodes and the ability to create a global namespace for access to large numbers of files. Standard hardware and software are integrated to provide the systems and advanced features. The scaling capability lends itself to adapting the system to meet differing usage environments by configuring dual node pairs using the clustering capabilities of GPFS.
