FCoE
Fibre Channel over Ethernet (FCoE) is a computer network technology that encapsulates Fibre Channel frames over Ethernet networks. This allows Fibre Channel to use 10 Gigabit Ethernet networks (or higher speeds) while preserving the Fibre Channel protocol. The specification was part of the International Committee for Information Technology Standards T11 FC-BB-5 standard published in 2009. Functionality FCoE transports Fibre Channel directly over Ethernet while being independent of the Ethernet forwarding scheme. The FCoE protocol specification replaces the FC0 and FC1 layers of the Fibre Channel stack with Ethernet. By retaining the native Fibre Channel constructs, FCoE was meant to integrate with existing Fibre Channel networks and management software. Data centers used Ethernet for TCP/IP networks and Fibre Channel for storage area networks (SANs). With FCoE, Fibre Channel becomes another network protocol running on Ethernet, alongside traditional Internet Protocol (IP) t ...

Computer Network
A computer network is a set of computers sharing resources located on or provided by network nodes. The computers use common communication protocols over digital interconnections to communicate with each other. These interconnections are made up of telecommunication network technologies, based on physically wired, optical, and wireless radio-frequency methods that may be arranged in a variety of network topologies. The nodes of a computer network can include personal computers, servers, networking hardware, or other specialised or general-purpose hosts. They are identified by network addresses, and may have hostnames. Hostnames serve as memorable labels for the nodes, rarely changed after initial assignment. Network addresses serve for locating and identifying the nodes by communication protocols such as the Internet Protocol. Computer networks may be classified by many criteria, including the transmission medium used to carry signals, bandwidth, communications pro ...

Ethertype
EtherType is a two-octet field in an Ethernet frame. It is used to indicate which protocol is encapsulated in the payload of the frame and is used at the receiving end by the data link layer to determine how the payload is processed. The same field is also used to indicate the size of some Ethernet frames. EtherType is also used as the basis of 802.1Q VLAN tagging, encapsulating packets from VLANs for transmission multiplexed with other VLAN traffic over an Ethernet trunk. EtherType was first defined by the Ethernet II framing standard and later adapted for the IEEE 802.3 standard. EtherType values are assigned by the IEEE Registration Authority. Overview In modern implementations of Ethernet, the field within the Ethernet frame used to describe the EtherType can also be used to represent the size of the payload of the Ethernet Frame. Historically, depending on the type of Ethernet framing that was in use on an Ethernet segment, both interpretations were simultaneous ...

Network Protocols
A communication protocol is a system of rules that allows two or more entities of a communications system to transmit information via any kind of variation of a physical quantity. The protocol defines the rules, syntax, semantics and synchronization of communication and possible error recovery methods. Protocols may be implemented by hardware, software, or a combination of both. Communicating systems use well-defined formats for exchanging various messages. Each message has an exact meaning intended to elicit a response from a range of possible responses pre-determined for that particular situation. The specified behavior is typically independent of how it is to be implemented. Communication protocols have to be agreed upon by the parties involved. To reach an agreement, a protocol may be developed into a technical standard. A programming language describes the same for computations, so there is a close analogy between protocols and programming languages: ''protocols are to co ...

SCST
SCST is a GPL licensed SCSI target software stack. The design goals of this software stack are high performance, high reliability, strict conformance to existing SCSI standards, being easy to extend and easy to use. SCST does not only support multiple SCSI protocols (iSCSI, FC, SRP, ...) but also supports multiple local storage interfaces (SCSI pass-through, block I/O and file I/O) and also storage drivers implemented in user-space via the scst_user driver. In order to reach maximum performance SCST has been implemented as a set of kernel drivers. SCST is often combined with RAID, data deduplication and/or high-availability cluster software to augment its functionality. The SCST software stack is the basis software of many SAN systems. Several world records have been set with SAN systems based on SCST. SCST competes with LIO Target for the same purpose of providing a generic SCSI target module inside the Linux kernel. For the narrower purpose providing a Linux iSCSI target, the ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

LIO Target
In computing, Linux-IO (LIO) Target is an open-source implementation of the SCSI target that has become the standard one included in the Linux kernel. Internally, LIO does not initiate sessions, but instead provides one or more Logical Unit Number In computer storage, a logical unit number, or LUN, is a number used to identify a logical unit, which is a device addressed by the SCSI protocol or by Storage Area Network protocols that encapsulate SCSI, such as Fibre Channel or iSCSI. A LUN m ...s (LUNs), waits for SCSI commands from a SCSI initiator, and performs required input/output data transfers. LIO supports common storage fabrics, including FCoE, Fibre Channel, IEEE 1394, iSCSI, iSCSI Extensions for RDMA (iSER), SCSI RDMA Protocol (SRP) and Universal Serial Bus, USB. It is included in most Linux distributions; native support for LIO in QEMU/Kernel-based Virtual Machine, KVM, libvirt, and OpenStack makes LIO also a storage option for cloud deployments.

HyperSCSI
HyperSCSI is an outdated computer network Protocol (computing), protocol for accessing storage by sending and receiving SCSI commands. It was developed by researchers at the Data Storage Institute in Singapore in 2000 to 2003. HyperSCSI is unlike iSCSI in that it bypassed the internet protocol suite (TCP/IP) and works directly over Ethernet to form its storage area network (SAN). It skipped the routing, retransmission, segmentation, reassembly, and all the other problems that the TCP/IP suite addresses. Compared to iSCSI, this was meant to give a performance benefit at the cost of IP's flexibility. An independent performance test showed that performance was unstable with network congestion. Since HyperSCSI was in direct competition with the older and well established Fibre Channel, and the standardized iSCSI, it was not adopted by commercial vendors. Some researchers at Huazhong University of Science and Technology noted the failure to provide any transport layer protocol, so implemen ...

Brand
A brand is a name, term, design, symbol or any other feature that distinguishes one seller's good or service from those of other sellers. Brands are used in business, marketing, and advertising for recognition and, importantly, to create and store value as brand equity for the object identified, to the benefit of the brand's customers, its owners and shareholders. Brand names are sometimes distinguished from Generic brand, generic or store brands. The practice of branding - in the original literal sense of marking by burning - is thought to have begun with the ancient Egyptians, who are known to have engaged in livestock branding as early as 2,700 BCE. Branding was used to differentiate one person's cattle from another's by means of a distinctive symbol burned into the animal's skin with a hot branding iron. If a person stole any of the cattle, anyone else who saw the symbol could deduce the actual owner. The term has been extended to mean a strategic personality for a produ ...

Dell Networking
Dell Networking is the new name for the networking portfolio of Dell. In the first half of 2013, Dell started to re-brand their different existing networking product brands to Dell Networking. Dell Networking will be the new name for the networking-equipment that was known as Dell PowerConnect as well as the Force10 portfolio. History Dell used to be mainly a so-called box-shifter: they produced computers that could (only) be bought directly from Dell, but they didn't offer complete solutions. With the acquisition of Perot Systems Dell entered the market for the -more profitable- services market and also expanded on the software and system-management-market by buying KACE Networks, Quest Software, AppAssure and Credant Technologies. Other notable acquisitions include storage systems like EqualLogic, thin-client producer Wyse and firewall/security producer SonicWall. Networking In 2011, Dell took over high-end network-equipment producer Force10 Networks that mainly produces mul ...

Force10
Dell Force10 (formerly nCore Networks, Force10 Networks), was a United States company that developed and marketed 10 Gigabit and 40 Gigabit Ethernet switches for computer networking to corporate, educational, and governmental customers. It had offices in North America, Europe, and the Asia Pacific region. In August 2011, Dell completed the acquisition of Force10 and changed the name to Dell Force10. In mid 2013, the Force10 designation was dropped from the products in favor of the data center networking line of the Dell Networking brand, and some of the other product lines were sold. History Founding The company was founded by PK Dubey, Naresh Nigam and Som Sikdar. It was named by founder Som Sikdar, an avid sailor, after Beaufort Force 10 (Storm, Whole gale) on the Beaufort scale for wind speeds, indicating a storm with high speed winds, and matched their focus on 10 Gigabit Ethernet switching and routing products. Acquisition In January 2009, Force10 was acquired by ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
