References Unified Fabric White PaperFibre Channel over Ethernet FCo. E Contents Unified fabric is the convergence of all the various data center IO technologies over Ethernet see Figure 1. One of the most disruptive technologies introduced in the Cisco Nexus family of switches in this area is the ability to transport SAN traffic with Fibre Channel over Ethernet FCo. E. The benefits of FCo. E are easy to understand. In a typical data center, the backend servers are connected to a separate network infrastructure dedicated to storage traffic. Merging the devices that handle Fibre Channel FC and Ethernet traffic provides savings in term of equipment purchase as well as space, power, and cooling costs. Figure 1 Aggregation and Access FC Switches Merged with Ethernet Counterparts An FC network is lossless, meaning that the protocol has a built in mechanism that prevents frame drops caused by congestion. FC can be transported only over a lossless Ethernet network. The technology required to implement such a multi hop lossless Ethernet network is not trivial or finalized. However, conservative SAN administrators should not disregard FCo. E because of this apparent bleeding edge complexity. You can enjoy the benefits of FCo. E with simple and proven topologies where the span of lossless Ethernet network is reduced to a single point to point link. Figure 2 shows an example of FCo. E pushed to the edge of the network. Figure 2 FCo. E Benefits Provided when Deployed at the Network Edge In this scenario, FCo. E is used only between the hosts and the access switches. Most of the savings in operating expenses OPEX and capital expenses CAPEX promised by FCo. E are already available because the edge of the network features the highest density of FC switches, host bus adapters HBAs, and dedicated cabling. Focusing uniquely on this very simple and efficient design, this document does the following Provides an overview of the standards developed for FCo.

E solution and the traditional separate FC fabric Solution Components This section introduces the various elements necessary for implementing FCo. E at the edge of the network. Note This section is not intended to be a reference on FCo. E. For additional details, see IO Consolidation in the Data Center, Silvano Gai and Claudio De Santi, Cisco Press, ISBN 1. X. Connection HostSwitch A server connects to an FC fabric via an HBA. These servers also feature another set of network adapters to connect to an Ethernet network. For each server, separate cards with separate cables connect to separate switches, as shown on the left side of Figure 3. Figure 3 Host Switch Connection The solution suggested in this guide shown on the right side of Figure 3 consists in replacing the HBA and the Ethernet card with a converged network adapter CNA. This unique CNA connects via a single 1. Gigabit link to an Ethernet switch that is also an FC forwarder FCF that is, an Ethernet switch with FCo. E capabilities. For each server, at least two HBAs, two cables typically with Small Form Factor Pluggable SFP and a transceiver, and two FC ports on an access FC switch are saved with the converged solution. This immediate CAPEX reduction is further complemented by OPEX savings because the model requires fewer devices and thus less power and cooling. Figure 3 also shows that the CNA is controlled by two different drivers for FC and Ethernet. This means that the virtualization of FC traffic over Ethernet is entirely transparent to the operating system of the server because the CNA appears as two distinct cards. The FC traffic, represented by the green line, is transported over Ethernet to a virtual FC interface on the access switch. From there, it is forwarded using native FC interfaces in the particular FCo. E at the edge scenario described in this document. The following section introduces the various standard components involved The FCo. E standard specifies the FCF and defines how the traffic is encapsulated in Ethernet frames. The FCo. E standard also introduces the FCo. E Initiation Protocol FIP, which is run between the CNAs to discover the FCF automatically. To support FCo. E, the underlying Ethernet must be lossless. The FCo. E specification does not address how this must be achieved, so this design relies on the following IEEE standards On the point to point connection between the CNA and the Ethernet switch, priority based flow control PFC, as defined in 8. Qbb, provides a mechanism similar to the buffer to buffer credit traditionally used by FC. The implementation of the above PFC requires coordination between the switch and the CNA. IEEE 8. 02. 1. Qaz, a standard based on Link Layer Discovery Protocol LLDP, is used to discover and set up the various Ethernet capabilities required. T1. 1 Standard This section discusses FCo. E encapsulation as defined by the T1. FC layers and the FCo. E Initialization Protocol FIP. FCo. E Encapsulation FCo. E is defined in the same T1. FC BB 5 that also defines Fibre Channel over IP FCIP, another standard that is now well accepted in the SAN community. Figure 4 shows the format of an FCo. E frame. Figure 4 FCo. E Encapsulation An entire unmodified FC frame is included in a single Ethernet frame there is no fragmentation. As a result, jumbo frames are required on links supporting FCo. E because the FC payload can go up to 2. Fields such as the start of frame SOF and end of frame EOF use symbols specific to FC lower layers. They are re encoded following the existing model used by FCIP and carried in the FCo. E header enclosing the FC frame. From the perspective of Ethernet, FCo. E is just another upper layer protocol, such as IP, identified by a specific Ether. Type 0x. 89. 06. From the perspective of FC, FCo. E is just a different way of implementing the lower layers of the FC stack. Fibre Channel Layers To highlight the changes introduced by FCo. E, it is necessary to provide a high level overview of the various layers in the FC protocol stack. The bottom layers FC 0 and FC 1 are responsible for the encoding and the error control on a particular medium. FC 2. P is responsible for the frame format and the control functions necessary for information transfer. In particular, this layer implements the buffer to buffer credit mechanism that makes FC lossless. Up to this level, there is only point to point communication between a single physical N PNPort and a single physical F port PFPort. Figure 5 shows the FC stack at a high level on a node a host with an HBA with an N port on the left connecting to the F port of a FC switch on the right. Figure 5 FC Stack When a node connects to the fabric, it performs a fabric login during which it is assigned a 3 byte FC address, or FCID. This FCID is used for routing frames across the fabric. The entity that received the address is a virtual N port VNPort, and the address is provided by the virtual F port VFPort to which it connects. Because it is useful to allow a node to initiate several connections and receive several addresses, there might be more than one VNPort. Pocket mkc 4. 4 by Publicaciones Makro Computo.
