Serial ATA (SATA) is an inexpensive serial-based storage technology that is shaking up the network storage industry. But while SATA is less expensive than Fibre Channel, don't look for it to replace Fibre Channel at the high end. Instead, look for SATA to find its place in storage solutions that mix SATA, SCSI, and Fibre Channel.
Fibre Channel and SATA
* Fibre Channel is a high-speed proprietary storage network infrastructure that was developed in part because of the limitations of SCSI (Small Computer System Interface). It remains the standard for high performance Storage Area Networks.
* Serial ATA is a disk drive interface based on serial cabling technology. (USB and Ethernet are other examples of serial cable technology.) SATA is more efficient and can carry more data than traditional Parallel ATA or IDE drives, but does so at about a third of the cost of SCSI.
* SATA is not a replacement technology for high performance Fibre Channel drives. However, SATA could lower the overall cost of a Storage Area Network by performing certain secondary storage tasks, such as backup. A SATA disk array, for example, would be faster than backup tape drives.
