Product Overview of Dell QLE2742-DEL
Dell QLE2742-DEL is a dual-port FC (Fibre Channel) Host Bus Adapter (HBA) that offers 32GB bandwidth. It is designed to provide high-speed connectivity for storage area networks (SANs) in data centers. This HBA is manufactured by QLogic, which is a leading provider of networking infrastructure solutions.
Host Bus Adapter
A Host Bus Adapter is a hardware device that allows a computer to communicate with a storage device over a network. An HBA acts as an interface between the computer's CPU and the storage device's disk interface. The HBA takes data from the CPU and transmits it to the storage device, and vice versa. HBAs are commonly used in SANs, where multiple computers need to access shared storage.
Fibre Channel is a high-speed network technology that is commonly used in SANs. Fibre Channel provides high-bandwidth, low-latency connectivity between servers and storage devices. Fibre Channel networks can transfer data at speeds of up to 128GB per second.

What is A Fiber Channel?
A fiber channel (FC) is a computer networking protocol used for transferring data between one or several computer systems at extremely high speeds. The successive technology generations of fiber channels run at data rates ranging from 1-128 (gigabit per second rates).
Fiber channels were initially developed for supercomputers. However, in recent times, they are commonly used in storage networking server environments, serving as a substitute to various serial storage technologies and small computer system interfaces (SCSI), aka "Scuzzy."
Fiber Channels are the integral components for data transmission among data centers, computer servers, switches, and storage at up to 128 Gbps.
History of Fiber Channel
Fiber channel began in 1988 to consolidate the advantages of multiple physical layer applications, including HIPPI, ESCON, and Scuzzy (SCSI). It is regulated in the T11 Technical Committee of the INCITS (International Committee for Information Technology Standards). The fiber channel effectively overcame the challenges of sustaining signal timing coherence across all the data-signal cables (50 for HIPPI and 8, 16, and 32 for scuzzy). Consequently, a receiver can conclude when all the electrical signal values are stable and sound for synchronous reception sampling.
The advantages of Fiber Channel
Storage Area Networks (SAN) and Network Attached Storage (NAS) have enjoyed increased popularity over the years. Fiber channel, on the other hand, has played a vital role in this development. While SAN employs fiber channel as the transmission protocol for storage provisioning, a NAS usually uses TCP/IP as the transmission protocol, NFS, or other file sharing applications for storage provisioning. Below are some of the advantages of the fiber channel.
Native fiber drives bring about high-level reliability and data integrity. They are dual-ported as a standard feature. Arguably the critical advantage that fiber channel SANs once held and still holds is the speed. It remains as one aspect that differentiates the fiber channel SANs from those of the Ethernet.
Fiber channel remains the ideal solution for IT professionals seeking high-performance, cost-effective information storage and reliability at high speeds. Given that fiber channel is a lossless protocol, it is often rated higher than the Ethernet network. Sent frames must be received in order and not dropped by the switch. This feature, however, is sometimes absent with Ethernet.
Other benefits of fiber channel FC include LUN masking, cost, and size. Allhdd.com fiber channel controllers are from trusted brands and are available at give-away prices. Please choose from our wide range collection and enjoy a 30-day warranty and fast delivery across 48 U.S. states.
