This allows Fibre Channel to use 10 Gigabit Ethernet networks or higher speeds while preserving the Fibre Channel protocol. This removes the need to run separate LAN and SAN networks, allowing both networks to be run over a single converged network.

Survey on converged data center networks with DCB and FCoE: standards and protocols Abstract: Data center networks today face exciting new challenges in supporting cloud computing and other data-intensive applications. In conventional DCNs, different types of traffic are carried by different types of networks, such as Ethernet and Fibre Channel. Typically, Ethernet carries data traffic among servers in LANs, and Fibre Channel connects servers and storages in storage area networks. Due to the existence of multiple networks, the network cost, power consumption, wiring complexity, and management overhead are often high.

With FCoE it is possible to use a uniform physical infrastructure for both the transmission of Fiber Channel and conventional Ethernet. The scalability and the higher bandwidths of Ethernet-based network structures with the currently common 10 Gbps soon also 40 or Gbps represent significant advantages. On the other hand, the use of Ethernet for the transport of Fiber Channel frames also has disadvantages of the classic Ethernet protocol, such as the loss of frames in overload situations, so that some improvements to the Ethernet standard are necessary to ensure reliable transmission based on Ethernet. These extensions are being promoted under the term data center bridging. In this regard, the consolidation of Ethernet-based networks and Storage Area Networks SAN on a common, high-performance physical infrastructure should be mentioned. The main advantages here are likely to be the significantly lower cabling effort and the overall lower investment costs for a common infrastructure, as well as the better resource utilization of the physical infrastructure.

This allows Fibre Channel to use 10 Gigabit Ethernet networks or higher speeds while preserving the Fibre Channel protocol. By retaining the native Fibre Channel constructs, FCoE was meant to integrate with existing Fibre Channel networks and management software. Since classical Ethernet had no priority-based flow control , unlike Fibre Channel, FCoE required enhancements to the Ethernet standard to support a priority-based flow control mechanism to reduce frame loss from congestion. Fibre Channel required three primary extensions to deliver the capabilities of Fibre Channel over Ethernet networks:.

 Что это. - Стратмор только сделал вид, что звонил по телефону. Глаза Хейла расширились. Слова Сьюзан словно парализовали его, но через минуту он возобновил попытки высвободиться. - Он убьет .

 Я кое-что нашла, сэр! - возбужденно сказала.  - Висячие строки в источнике. Альфа-группы повсюду.

Advanced FCoE: Extension of Fibre Channel over Ethernet

Фонтейн долго молчал. Потом, тяжело вздохнув, скомандовал: - Хорошо. Запускайте видеозапись. ГЛАВА 117 - Трансляция видеофильма начнется через десять секунд, - возвестил трескучий голос агента Смита.  - Мы опустим каждый второй кадр вместе со звуковым сопровождением и постараемся держаться как можно ближе к реальному времени.

Водитель кивнул, с любопытством разглядывая пассажира в зеркало заднего вида. - Колдун, - пробурчал он себе под нос.  - Ну и публика собирается там каждый вечер.

Беккер зашагал по комнате. - На руке умершего было золотое кольцо. Я хочу его забрать. - У м-меня его. Беккер покровительственно улыбнулся и перевел взгляд на дверь в ванную.
