There are several storage network protocols to choose from, including iSCSI, Fibre Channel and NVMe over Fabric. Review the performance, reliability, complexity and cost of each before deciding which one to use.
A SFP (Small Form-Factor Pluggable) transceiver is a compact, hot-swappable device that can be used for both transmit and receive data and also plugs into a physical port of a network device. It is used in the communication network and has a transmitting side and receiving side. The SFP transceiver has a laser which communicates with the receiving side of the other optic on the other side. SFP transceivers are designed to support several communication standards including SONET, Gigabit Ethernet and Fibre Channel, and their interfaces on a networking device such as a router provides a modular device that can be freely adjusted to fiber optic and copper networking specifications.
L-com has launched a series of active optical cables (AOCs), designed to address high-speed data centers and enterprise networking applications. The new AOCs are hot swappable, pluggable cable assemblies that support high-speed Ethernet, InfiniBand and Fibre Channel connectivity (10Gbps-100Gbps). Although they use the same electrical interface as Direct-Attach Cables (DACs), AOCs utilize fiber-optic cable instead of copper wiring, so they are able to support distances up to 100 meters. Furthermore, DACs are limited by crosstalk since they utilize copper cabling and generally cannot support distances over 10 meters.
Smartoptics’ new line of optical transceivers and open line system for use in 32G Fibre Channel storage area networks complement the company’s existing line of 8G and 16G Fibre Channel products.The 32G Fibre Channel optical transceivers are available in the SFP28 form factor for use in the platforms of a variety of switch vendors. The optical modules can be used with passive filters as well as Smartoptics’ active open line systems to support reaches up to 80 km between data centers.
Reacting to the overwhelming positive feedback and the requests for additional information from the first webcast, Protocol Analysis for High-Speed Fibre Channel Fabrics, the Fibre Channel Industry Association is continuing its commitment […]
Broadcom’s Emulex® LPe35000-series HBAs are the first products released that comply with the FC-PI-7 standard*–the fastest single-lane serial transmission speed that features the hardened NVMe over Fibre Channel protocol (NVMe/FC), automatic buffer credit recovery, and more. Purpose-built for All-flash and […]
The IT storage industry is well known for using lots of technical jargon and convoluted terms. While many of these terms are super obscure, there are others that you definitely need to […]
Fibre Channel’s speed roadmap defines a well-understood technological trend: the need to double the bit rate in the channel without doubling the required bandwidth. In order to do this, PAM4 (pulse-amplitude modulation, […]
Got questions about Fibre Channel (FC) interoperability? You’re not alone. At our recent FCIA webcast “Fibre Channel Interoperability” we received many great questions as our experts discussed the many dimensions of FC […]
The choice between using Fibre Channel (FC) or other protocols is dictated by several factors, one of them being whether a dedicated SAN is required and/or desirable. Ethernet SANs are implemented in […]
