See the rising tide. A number of technological inflection points are confluencing to drive profound change in data storage: Flash memory is redefining its performance and economics, arrays with powerful CPUs are refactoring its architectural boundaries, converging SAN fabrics and commodity hardware are accelerating its proliferation, and virtualization and cloud computing are pushing its elasticity. RTS brings it all together with its new class of storage software, based on its LIO Unified Target, which is now the standard in Linux.


About Us

RTS was founded by an experienced team of serial entrepreneurs to redefine storage based on open industry standards.



RTS has established its Unified Target, which is at the core of its products, as a the standard storage engine in Linux.
