The IBM XIV Storage System was a line of cabinet-size disk storage servers. The system is a collection of modules, each of which is an independent computer with its own memory, interconnections, disk drives, and other subcomponents, laid out in a grid and connected together in parallel using either InfiniBand or Ethernet connections. Each module has an x86 CPU and runs a software platform consisting largely of a modified Linux kernel and other open source software.
