Converged data center_f_co_e_iscsi_future_storage_networkingEMC
This document discusses the future of storage networking, specifically comparing FCoE and iSCSI. It begins with an overview of how 10Gb Ethernet is enabling network convergence by allowing a single network to be used for both storage and regular network traffic. It then covers the iSCSI and FCoE protocols in more detail, explaining how iSCSI transports SCSI over IP networks using TCP, while FCoE encapsulates Fibre Channel frames in Ethernet to enable Fibre Channel over Ethernet. Finally, it discusses how these protocols support network virtualization and the evolution of converged infrastructure solutions.
Converged Data Center: FCoE, iSCSI, & the Future of Storage Networking ( EMC ...EMC
This document discusses storage networking protocols and converged data centers. It provides an overview of iSCSI, which transports SCSI over TCP/IP, allowing more flexible connectivity than Fibre Channel. Fibre Channel over Ethernet (FCoE) is also summarized, which encapsulates Fibre Channel frames in Ethernet to leverage Ethernet infrastructure for storage. Lossless Ethernet technologies like Data Center Bridging are required to support FCoE reliability. The document discusses how these protocols support server virtualization through virtual HBAs and NICs that present block storage to virtual machines over the virtual switch.
Frame Relay is a packet-switched WAN technology that transports variable-length frames over permanent virtual circuits (PVCs). It provides connection-oriented transmission of user data between two endpoints via a transparent logical link. Frame Relay operates at the data link layer and does not provide error or flow control, relying instead on higher layers for reliability. It offers bandwidth on demand and more efficient use of WAN links compared to traditional leased lines.
Fibre Channel is a high-speed network technology primarily used for storage networking. It provides serial data transfer at speeds of 1-8Gbps. Fibre Channel includes the advantages of both channels (speed and reliability) and networks (scalability). It supports various topologies including point-to-point, arbitrated loop (FC-AL), and switched fabric. The switched fabric topology uses 24-bit addressing and can scale to connect over 16 million devices across multiple switches. Fibre Channel operates at seven layers, with the physical layer defining cable types and speeds, and upper layers defining protocols encapsulated for transport.
Converged Networks: FCoE, iSCSI and the Future of Storage NetworkingStuart Miniman
FCoE allows Fibre Channel traffic to run over Ethernet networks using encapsulation. This convergence of networks simplifies infrastructure by using a single network for both storage and LAN traffic. Standards like FCoE and DCB/CEE are being developed to enable lossless Ethernet environments required for storage traffic. Early solutions involve direct server attachment to top-of-rack FCoE switches, but solutions are expanding to include blade servers and multi-hop configurations. Widespread adoption will take time as standards mature and solutions expand beyond proof-of-concept deployments.

Fibre Channel over Ethernet (FCoE), iSCSI and the Converged Data CenterStuart Miniman
The document discusses Fibre Channel over Ethernet (FCoE) and iSCSI as protocols for converged data centers. It compares the FCoE and iSCSI protocol stacks and how they leverage 10Gb Ethernet. FCoE encapsulates Fibre Channel frames within Ethernet while iSCSI carries SCSI commands over TCP/IP. Emerging standards like FCoE and Converged Enhanced Ethernet aim to drive I/O consolidation over a single Ethernet network.
The document discusses storage area networks (SANs) and their evolution. It begins by explaining that a SAN carries data between servers and storage devices through fibre channel switches. Early SANs used a simple hub connectivity device, while modern SANs use switches for better performance. SANs consist of servers, network infrastructure like switches, and storage arrays. Fibre channel is the connectivity protocol used in SANs and allows for point-to-point, arbitrated loop, and switched fabric configurations. The document then covers fibre channel addressing, frame structure, data organization, flow control, classes of service, and the components and evolution of SANs.

This document provides an overview of Ethernet technology, including its history and standards, hardware specifications, access methods, types of Ethernet, OSI and TCP/IP protocol layers, and connecting devices like switches, routers and firewalls. It also includes a hands-on example of network traffic between devices with different IP addresses, showing how switches, routers and firewalls direct the traffic between local and external networks.
This module discusses IP SAN and Fibre Channel over Ethernet (FCoE) protocols. It describes the components and topologies of iSCSI and FCIP for IP SAN, including iSCSI initiators, targets, gateways and discovery. It also covers Fibre Channel over Ethernet, including its drivers, components like converged network adapters and switches, frame mapping, and requirements for lossless Ethernet like priority flow control and congestion notification. The goal is to explain how these protocols provide block storage over IP networks and enable consolidation of FC and Ethernet infrastructures.
Frame Relay is a packet-switched protocol that operates at the physical and data link layers of the OSI model. It was originally designed for ISDN interfaces but is now used over various network interfaces. Frame Relay is more efficient than X.25 and offers higher performance without retransmission capabilities. Frame Relay uses data terminal equipment (DTE) connected to data circuit-terminating equipment (DCE) via physical and link layer connections to transmit data packets over wide area networks.
