Fibre Channel Networking Model
Fibre Channel Networking Model It is easier to understand a communications protocol if it is first broken down into parts or layers. For better understanding, the Fibre channel protocol has been broken into five...
SFP Types
SFP Types Short Wavelength (SWL) Long Wavelength (LWL) Extended Long Wavelength (ELWL) Wave Division Multiplexing (WDM) SWL Fiber Optic SFP Module – Based on short-wavelength 850 nm lasers supporting 2 and 4 Gbit/sec...
Fiber Optic Cables
Fiber Optic Cables In FC SAN, optical fibre cables are used as data transmitters. In FC SAN data transmits in the form of light. Fiber types are available in two types: single mode fiber...
What is Zoning?
What is zoning Zoning means restricting the scope of an initiator (host) to a particular target (storage array) in fabric. An initiator can see only the devices from a particular storage array that is...
How to take backup of Brocade switch configuration file in local server?
How to take backup of Brocade switch configuration file in local server The configuration file contains all zoning information and configuration settings of the fabric. To take a backup of the configuration file, first...
Fibre Channel Classes of service
Fibre Channel Classes of service Applications might require different levels of service and guarantees regarding delivery, connectivity, and bandwidth. Some applications need to have a bandwidth that is dedicated to them during the data...
Converged Network Adapter
Converged Network Adapters Converged Network Adapters (CNAs) can run both Ethernet and Fibre Channel traffic at the same time. These CNAs combine the functions of an HBA and a Network Interface Card (NIC) on...
Fibre Channel Topologies
Fibre Channel Topologies Topology is the way of approach to connecting devices to form a network. Fibre Channel-based networks support three types of base topologies: Point-to-point Arbitrated loop Switched fabric Switched fabric further classified...
What is Congestion in SAN fabric?
Congestion When over-subscription occurs, it leads to a condition called congestion. When a node is unable to use as much bandwidth as it wants, because of contention with another node, then there is congestion. A...
