IBM Elastic Storage System - Simple, Scalable Building Blocks for High-performance Hybrid Cloud Storage

Storage made simple for AI and hybrid cloud modernization

IBM Elastic Storage System (ESS) is a modern implementation of software-defined storage, making it easier for you to deploy fast, highly scalable storage for AI and big data. With the lightning-fast NVMe storage technology and industry-leading file management capabilities of IBM Spectrum Scale, the ESS 3000 and ESS 5000 nodes can grow to over YB scalability and can be integrated into a federated global storage system.


IBM ESS can consolidate storage requirements from the edge to the core data center to:

  • Rereduce inefficiency

  • Lower acquisition costs

  • Simplify storage management

  • Eliminate data silos

  • Support multiple demanding workloads

  • Deliver high performance throughout your organization

IBM ESS can also handle storage requirements for Kubernetes and Red Hat OpenShift.

What is IBM Spectrum Scale?

IBM Spectrum Scale™ is a cluster file system that provides concurrent access to a single file system or set of file systems from multiple nodes. The nodes can be SAN attached, network attached, a mixture of SAN attached and network attached, or in a shared cluster configuration. This enables high performance access to this common set of data to support a scale-out solution or to provide a high availability platform.


IBM Spectrum Scale™ has many features beyond common data access including data replication, policy based storage management, and multi-site operations. You can create a cluster of AIX® nodes, Linux nodes, Windows server nodes, or a mix of all three. IBM Spectrum Scale can run on virtualized instances providing common data access in environments, leverage logical partitioning, or other hypervisors. Multiple IBM Spectrum Scale™ clusters can share data within a location or across wide area network (WAN) connections.

IBM Spectrum Scale™ meets the challenges of a parallel high-performance solution with global file and object data access for managing data at scale with the distinctive ability to perform archive and analytics in place.
