Can an FC interface be used to connect a hard drive
Seagate offers many hard drive models with the Fibre Channel (FC) interface. Thus to get to work on a PC server or workstation you will need a PCI or PCIe to FC adapter/HBA and applicable drivers to attach the drive. Thus you are correct. The interface of an internal hard disk drive defines the way it connects to the rest of the host system, usually the computer's motherboard, and interacts with it. Over the years, the technology used for communication has seen significant developments. First of all, the need for faster data. Hard disk drives are accessed over one of a number of bus types, including parallel ATA (PATA, also called IDE or EIDE; described before the introduction of SATA as ATA), Serial ATA (SATA), SCSI, Serial Attached SCSI (SAS), and Fibre Channel. Using optical fiber to connect devices, fibre channel supports full-duplex data transfer rates up to 100 MB per second. Fibre Channel is a high-speed network that is designed for data storage, and it offers much better performance than the SATA or SAS interfaces that are.
