Data Center storage Evolution--fcoe Data Center Three basic: Host network storagedriven by cloud computing, the storage infrastructure has evolvedThe traditional storage architecture Das, San in the development of complex cabling, energy consumption of the shortcomings (original), need to make fundamental changes to the architecture. FCoE is an undisputed evolutionary trend in the industry, with a focus on the origins and principles of technology, and essentially explaining why FCoE is the only evolutionary direction recognized.
Figure FC vs Ethernet vs FCoE Evolution Roadmap The evolution of the 2x allows FC to fall behind, and future storage networks will gradually transition to Ethernet architectures
Figure Traditional Data center storage architecture vs. FCOE Retrofit Storage Architectureas you can see, the typical single-hop architecture allows you to save:25% of hardware devices40% of network cables50% of network cards
Figure OSI Network protocol stack vs FC network protocol stackevolution of the FCoE multiplexing F2-F4 layer to the standard transport layer and aboveThe F0 and F1 are hosted on the Ethernet link layer and are connected to 2 worlds by a redesigned FCoE control plane (map)
Summary This chapter is more content, storage is a relatively independent technical field, so storage media, storage devices are not too much introduction,This paper focuses on the open extended storage architecture in the data center area, and introduces the evolution direction of the mainstream technology of San. The origin and principle of FCoE, realize the idea, for further study.
