The Pieces to Managing FCoE

John CrandallBrocade


Abstract

This presentation will identify and provide an overview to the many implementation pieces a client and FCoE switch and CNA vendor may need to consider for managing an FCoE environment including discovery and configuration. These pieces may include standards from the SNIA, DMTF, and T11. The presentation will attempt to identify the possible gaps in these standards and how they may be addressed and will also examine whether a client can hooks all these pieces together and if so how?

Learning Objectives

What are the current and future management standards

How do you hook the pieces together What are the gaps and how might they be addressed

Profiles almost done

DSP 1097 – Virtual Ethernet Switch Profile Specializes the autonomous Virtual System Profile. This

profile defines the minimum top-level object model needed to define a virtualization system’s internal Ethernet switch.

DSP 1050 – Ethernet Port Resource Virtualization Profile Specializes the abstract Resource Allocation Profile and

the Allocation Capabilities Profile to specify the allocation and management of a host computers Ethernet network access, in support of virtual computer systems ability to access external and internal network.
