LayerZero Power Systems Introduces the eOSI Model  

Chagrin Falls, Ohio (July 26, 2012) LayerZero Power Systems, Inc. has introduced the Extended Open System Interconnection (eOSI) model, an updated version of the OSI model.  The eOSI Model is an abstract model that describes architecture of data communications for networked computers.  The eOSI Model is a conceptual framework that consists of logical layers that build upon each other, allowing for data center professionals to more effectively identify and resolve individual problems. 

The Extended Open Interconnection Model consists of eight individual layers; User, Application, Presentation, Session, Transport, Network, Data, Physical, and Foundation.  The eOSI Model includes the addition of the Foundation Layer, reflecting on the importance of power reliability in data centers.  Foundation Layer (Layer 0) components include Static Transfer Switches, Power Distribution Units, and Remote Power Panels. 

The Open System Interconnection (OSI) reference model was first developed by the International Organization for Standardization in 1977, and has since remained unchanged.  To address the challenge of effectively managing data centers in a rapidly evolving environment, the updated eOSI Model is designed to address power reliability within the data center infrastructure.  Modern data center power systems are designed to provide maximum reliability, as the computer and IT equipment which these power systems serve are very sensitive to momentary losses of power.  The Foundation Layer is the base layer in the eOSI Model, as all components of the Physical Layer ultimately depend on reliable power. 

Layer 0, the Foundation Layer of the eOSI reference model, is comprised of reliable, safe, information centric and a highly connected set of power distribution products and processes.  The introduction of the eOSI Model exemplifies the commitment of LayerZero Power Systems to providing data centers with the most reliable power distribution solutions in the world.  LayerZero Power Systems strives to provide a best-in-class experience, and the introduction of the Extended Open Interconnection Model is the latest example of the how the company contributes to continuous innovation and technological advancement within the data center industry. 

LayerZero Power Systems has introduced a wide range of power reliability technologies to the data center industry, including Triple Modular Redundant Static Transfer Switches, the finger-safe SafePanel™ Panel Board, and the patented Dynamic Phase Compensation technology.  Designed to maximize power reliability in data centers, LayerZero Power Systems products are designed for operator safety, power quality monitoring, and open connectivity.
