What is a Fibre Channel Disk within an EMC SAN?
Posted on 2010-09-08
I'm confused as to what a Fibre Channel Disk is!
I understand that Fibre Channel Protocol (FCP) is a network technology similar to TCP/IP. Also, I understand that for storage, SATA or SCSI can be transported over FCP.
However, our CLARiiON SAN has two types of disks which it calls SATA and FC.
I think I understand SATA as SATA being carried over FCP.
However, is the FC disk SCSI being carried over FCP? Or is the FC disk some type of FC protocol for transferring data carried over FCP?
Finally, does FCP operate in a similar fashion to the TCP/IP stack i.e. are the SATA/SCSI command encapsulated within a FCP "packet"?
