Scalability

IBM Elastic Storage Server scales in a building block approach – capacity, bandwidth and the single namespace increases as more building blocks are added to scale out the entire solution. If the solution is sold as standalone, the POWER8 processor-based IBM Elastic Storage Server management server will act as the quorum node.

Services

  • IBM Elastic Storage Server hardware installation is included at no charge.
  • IBM Lab Services is available for customer configuration and enablement support.

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. Optional warranty service upgrades to 24x7.
