IBM Elastic Storage Server is a modern implementation of software-defined storage, combining IBM Spectrum Scale software with IBM POWER8 processor-based I/O-intensive servers and dual-ported storage enclosures. IBM Spectrum Scale is the parallel file system at the heart of IBM ESS. IBM Spectrum Scale scales system throughput as it grows while still providing a single namespace. This eliminates data silos, simplifies storage management and delivers high performance. By consolidating storage requirements across your organization onto IBM ESS, you can reduce inefficiency, lower acquisition costs and support demanding workloads.
