LAN and SAN consolidation and convergence
It is very demanding to implement and maintain two separate LAN and SAN networks in terms of both costs and processes. The main benefit of unified infrastructure for data communication is primarily that it cuts the costs associated with implementing an SAN network over a Fibre Channel. Due to the affordability and falling costs of 10GbE and Multi-Gigabit Ethernet solutions, convergent network infrastructure using Fibre Channel over Ethernet (FCoE) technology has become the basis of modern data centres.
FCoE management is at the host level; storage and switches are the same is with FC and the technology retains all the same functional principles; Ethernet is used solely for transmission.
Cisco converged switches
FCoE is one of the major components of Cisco Unified Data Center that enables multiprotocol networking for UCS servers, Cisco Nexus, and Cisco MDS platforms. In our solutions, we primarily use Cisco Unified Fabric portfolio and Cisco Unified Fabric platforms, Cisco Unixus® switches with FCoE support to enable FIP Snooping Bridge, NPV and FCF. CISCO Nexus offers high availability, security and performance with extremely low latency.
Like CISCO MDS Fiber Channel switches, the Cisco Nexus family switches use the Cisco NX-OS's - modular and scalable Cisco operating system.
The basic feature of the switch is Cisco DCE (Data Center Ethernet) technology that provides lossless data transfer over an Ethernet network. Priority Float Control allows you to divide the 10Gb band into eight independent channels - implement the data transmission separately including guaranteed congestion notification. DCE provides the management of eight queues with the option of setting a priority queue for lossless data transmission over the FCoE, but also over IP protocol - iSCSI or CIFS.
