Does SAS replace Fibre Channel?
No. Serial Attached SCSI and Fibre Channel are both advanced, enterprise-class solutions with specific attributes that influence their suitability for a given application. SAS offers outstanding performance and exceptional scalability on a local level. Fibre Channel is well suited for large enterprise use [e.g., a Storage Area Network (SAN)] due to its support of up to 16 million addresses and maximum cabling distance of ten kilometers.
