Fibre vs Fiber in SAN
Fibre vs Fiber: Fibre Channel was basically designed to support fiber optic cabling only. But industry also started using copper cables later to avoid the damage due to heat produced in storage systems. The...

What is Zoning?
Zoning Zoning means restricting to scope of an initiator (host) to particular target (storage array) in fabric. An initiator can see only the devices from particular storage array which is zoned to it. Zoning...
Fibre Channel Classes of service
Classes of service Applications might require different levels of service and guarantees regarding delivery, connectivity and bandwidth. Some applications need to have bandwidth that is dedicated to them during the data exchange like Tape...
