Disk drivesFibre Channel drives <<previous|next>> :How does IP storage differ from iSCSI, NAS and Fibre Channel?
Why go to 4 Gbit Fibre Channel if I'm not already using all of my 1 Gbit or 2 Gbit bandwidth?
Depending on your needs, there may not be a compelling argument to switch to 4 Gbit. People, even the vendors, get too focused on the bandwidth characteristics of Fibre Channel (FC). There's an obsession with bandwidth in general.
Going to a faster bandwidth may yield benefits in reduced latency, allowing time-sensitive applications to run faster. Similarly, the need to aggregate might allow a switch to fan in several slower servers to a faster 4 Gbit pipe to a 4 Gbit storage device.
