FCoE

FCoE

Abstract

The software has been developed by a team of experts with around 100+ yrs of collective experience in FC/FCoE space. HCL is one of the few engineering service providers who have the domain presence across the entire value chain in the storage domain. The group has 2500+ person-years of experience in various storage technologies.

The software is compliant as per FCoE Specification, FC-BB-5 Rev. 2.0 and FC Standards, such as FC-GS, FC-LS and FC-SW.

Excerpts from the Paper

The primary benefit of FCoE is network consolidation. Instead of separate FC HBAs for storage traffic and Ethernet NICs for corporate network traffic, the servers need a single Ethernet NIC. Since FCoE is a tunneling layer for FC, FC management concepts such as zoning and WWN still apply. This simplifies management as the administrator continues to see FC attributes everywhere in the topology.
 
FCoE requires enhancements to Ethernet for loss-less transport. TCP/IP adds latency and overhead to frames; not a difficult issue for traffic created for IP networks, but a serious problem for Fibre Channel frames in high performance environments. Running Fibre Channel over layer 2 Ethernet would avoid TCP/IP overhead, and CEE would provide the lossless environment that the Fibre Channel SAN requires. The other new features include robust congestion management, ability to prioritize Fibre Channel traffic over non-Fibre Channel traffic and frame latency comparable to Fibre Channel.
