Fibre Channel key features include...
Hot-pluggability ? Fibre Channel drives can be installed or removed while the host system is operational, which is crucial in high-end and heavy-use server systems where there is little or no downtime.
ANSI standard compliance for serial port interface ? Fibre Channel does not require special adapters, which can be expensive.
Speed ? In its intended environment, Fibre Channel is the fastest option available.
Cost effectiveness ? Relative to other high-end solutions, Fibre Channel is inexpensive because it does not require special adapters.
Loop resiliency ? Fibre channel provides high data integrity in multiple-drive systems, including Fibre Channel RAID.
Longer cable lengths ? Relative to LVD, Fibre Channel can maintain data integrity through significantly longer cables. This makes configuring multiple devices easier.
