The information in this appendix defines Fibre Channel, describes its

advantages, and outlines how it is in the Compaq StorageWorks RAID

Array 4000.

Fibre Channel has an integrated set of standards developed by the American

National Standards Institute (ANSI). This set of standards defines new

protocols for information transfer. Fibre Channel is an open industry standard

interconnect and high-performance serial I/O protocol that supports

simultaneous transfer of data using many different protocols. Fibre Channel

provides for extremely low error rates while performing at high data transfer

speeds. By using both an encoding scheme and strong cyclic redundancy

check (CRC) on each frame, Fibre Channel technology ensures data integrity.

The advantages of Fibre Channel technology include:

■ Higher Performance

q 100 MB/s data bandwidth on one Fibre Channel loop

q Higher I/O throughput

■ Connectivity Improvement

q Supports multiple data format packets (SCSI, IPI-3, and IP

protocols). The Compaq StorageWorks RAID Array 4000 supports

the SCSI protocol.
