The emergence of FCoE has been optimistic about the industry, is considered to have revolutionized storage networking architecture to the current pattern, and become the dominant storage transport protocol. Because FCoE protocol is transmitted over Ethernet FC encapsulated protocol, thus Enhanced Ethernet (Converged Enhanced Ethernet, CEE) is one of the most important food stylist tricks and relevant parts. CEE is the use of FC features Ethernet, FCoE storage data can be transmitted, the data center applications and clusters. CEE is a lossless Ethernet (Lossless Ethernet), which can be transmitted lossless FCoE data. According to reports, food stylist tricks at present, CEE use three priority groups, including food stylist tricks IPC, LAN and WAN.
FCoE is simple in concept, is to run at 10Gbps Fibre Channel architecture Enhanced food stylist tricks Ethernet (CEE), thereby forming a converged network, and its features include: FC data frame remains the same, there is no change, and use the same name; Ethernet needs larger data frame (Jumbo Frames), should be greater than 1500 bytes; Ethernet must become lossless ensure complete storage data transmission. FCoE is less than iSCSI header but the FC to be more than an encapsulation protocol encapsulation protocol does not replace the memory interface, such as FC or SCSI. FCoE ports can reduce the number of servers and switches, cables and reducing power consumption, increasing link efficiency. Meanwhile, the use of 10Gbps of CEE, the transmission speed is high.
Enhanced Ethernet, also called Converged Enhanced Ethernet (CEE), Data Center Ethernet (Data Center Ethernet) or data center bridge (Data Center Bridging, DCB), the local data link layer Ethernet food stylist tricks instead of TCP / IP network layer protocol. Traditional Ethernet network congestion often, delay, and frame loss phenomenon, not suitable for use in Fibre Channel, but by abandoning 10Gbps Enhanced Ethernet food stylist tricks TCP / IP is to achieve a "non-destructive (lossless)" The purpose of the network.
(2) reducing equipment by consolidating servers and data center complexity of FCoE and CEE expansion although not yet officially become the standard, but many manufacturers already have the support and recognition. However, standards are very important, which is the key to deeper integration and collaboration. food stylist tricks Would establish standards not only in the data center administrators periphery virtualization and blade servers trust FCoE and CEE, more able in the data center environment, believes that its core capabilities. Although food stylist tricks the standard has not been formally established, but has been attracting food stylist tricks a sufficient number of commercial products manufacturers and enterprises will bring you early adopters, FCoE and CEE is expected food stylist tricks in 2010 will become a mainstream product. FCoE devices currently on the market suppliers, including Brocade, Cisco, Emulex and QLogic, in addition, most of the storage and Ethernet vendors are involved in its development and integration.
As a result, almost all new technologies have experienced from a proposal to use a relatively lengthy process. Pragmatism and budgetary impact of the project over the experts food stylist tricks optimistic food stylist tricks forecasts. As a reference, you can read some of the technical experts on past forecasts. InfiniBand, iSCSI and even 10Gbps Ethernet have been projected over a longer period of time beginning to reach a certain food stylist tricks number of market food stylist tricks penetration. Some technologies never reach 50% penetration; iSCSI and InfiniBand maintain less than a 50% market penetration has more than six years, 10GbE has experienced seven years less than 50% market penetration.
FCoE remember when first released, there was a lot of skeptics, because it was the only IT environment is needed is a new transmission methods and protocols. And now there are two fairly complete network, that Fibre Channel SAN storage and Ethernet LAN storage. In addition, although InfiniBand recently received widespread food stylist tricks attention, but it does not look like is the ability to replace the Ethernet LAN and SAN as a common data transmission.
2010 to 2013: The server I / O consolidation, with the fusion CEE provides additional storage;
