The SSI modular blade specifications define the mechanical, electrical and management interfaces between the midplane and the compute blades, optional mezzanine cards, chassis management modules, and switch modules in a blade server platform. Compliance with the specifications’ requirements assures the interoperability of components from different hardware vendors.  Visit the SNIA website (formerly SSI Forum) to learn more about the benefits of blade servers based on SSI open specifications, how to obtain evaluation copies of the specifications, and SNIA membership.
