IBM Elastic Storage Server

Modern software defined storage system


  • Share data across applications with unified storage for file and object data
  • Run Hadoop and other big-data applications directly on enterprise storage
  • Scale capacity and/or performance in modular building blocks with automatic load balancing
  • Increase availability with faster rebuild of failed disks with erasure-coding-based declustered Redundant Array of Independent Disks (RAID) technology
  • Reduce latency and increase throughput powered by a parallel file system
  • Reduce risk with an integrated system built on input/output (I/O)-intensive IBM Power servers and IBM Spectrum Scale software
  • Reduce backup/restore times and eliminate filer sprawl and performance bottlenecks.

Big data is everywhere. Today’s exponential growth of data, transactions and digitally-aware devices is demanding larger and larger amounts of unstructured data storage and management. However, as each department or division attempts to satisfy its own storage needs, your organisation can find itself with many disparate systems isolated from each other. This can result in expensive resource duplication, complicated management and isolated pools of data. In addition, the resulting islands of information may hold valuable insights that may not be accessible in such a disparate environment.

Also, as disk drives become increasingly more dense, traditional RAID is no longer an effective mechanism for data protection since it can take from several hours or even days to rebuild a failed drive, which can increase the chance of multi-disk failures.

Scalability IBM Elastic Storage Server scales in a building block approach – capacity, bandwidth and the single name space increases as more building blocks are added to scale out the entire solution. If the solution is sold as standalone, the POWER8 processor-based maintenance server will act as the quorum node. An IBM Elastic Storage Server license is required.
Warranty 3-year parts, customer-replaceable unit (CRU) or on-site labour, limited warranty, with individual nodes retaining the warranty and service upgrade offerings for that IBM machine type; optional warranty service upgrades. Support is 09:00 to 17:00, next business day.
