                  YANG Baseline Switch Profile Background
                  draft-wbl-rtgwg-yang-ci-profile-bkgd-01

Abstract

   A YANG device profile is primarily a group of YANG models that are
   appropriate for use with a particular class of device or in specific
   device roles.  This document provides background and describes the
   rationale for a baseline data center switch device profile, e.g., for
   top-of-rack switches in data center converged infrastructure.  This
   rationale is based on the reuse of YANG models by the DMTF Redfish
   standard for management of converged infrastructure, but the
   resulting YANG device profile is intended to be useable by any YANG-
   based network management approach or protocol, as opposed to being
   specific to Redfish.

1.  Introduction

   *Disclaimer* - this is a -00 draft, whose primary goal is to capture
   the rationale for use of YANG for Redfish network management and the
   desirability of a baseline data center network switch profile,
   including providing technical background on the Redfish standard and
   its approach to network management.  The draft content is not
   polished, and the organization of the material is likely to change.

   A YANG device profile is primarily a group of YANG models that are
   appropriate for use with a particular class of device or in specific
   device roles.  This document provides background and describes the
   rationale for a baseline data center switch device profile, e.g., for
   top-of-rack switches in data center converged infrastructure.  The
   rationale is based on the reuse of YANG models by the DMTF Redfish
   standard for management of converged infrastructure, but the
   resulting YANG device profile is intended to be useable by any YANG-
   based network management approach or protocol; it is not intended to
   be Redfish-specific.

   In support of this rationale, this document provides background on
   how YANG is used in the Redfish management framework; the YANG
   modules are translated to Redfish schema definitions in order to
   enable reuse of the models are with Redfish-defined management
   protocols and related functionality.

2.  Motivation

   A common management framework with accompanying set of protocols and
   device models is desirable in systems management use cases.  A good
   example of this is in a converged infrastructure deployment within a
   data center.  Applications, servers, storage, appliances, and
   networking elements are assembled to create a combined coherent
   platform.  For the networking components in such an environment,
   there are platform management elements that are common with other
   types of systems such as thermal monitoring, physical enclosure,
   fans, and power supplies, as well as networking specific management
