Fiber disk?

hi refer below...

I think you mean fibre channel disk, fibre channel is a storage network technology, it's a bit like SCSI, SATA or SAS in that it can connect disks to controllers but it's a different protocol. They're generally much more expensive due to them being enterprise disks and demand being less than other connection protocols.

In a few cases they may be SATA disks with an interposer to convert from SATA to fibre channel, for example HP FATA disks.

Fibre channel (FC) can be the physical interface embedded in a disk drive, or you could have an external enclosure that has a FC interface with electronics that let you use SAS,SSD,SCSI,SATA drives on the inside.

If you want a better answer, be more specific.  Pictures would be nice if you are trying to identify what you have or need.

Don't think FC was developed by CERN, I thought it was HP, IBM and Sun in 1990, at least that's what the forward of PHYSICAL AND SIGNALING INTERFACE (FC-PH) REV 4.3 plus other sources suggests.

Agreed.  IBM holds the early patents for FC because much of it came from their channel and SSA patent portfolio.  DEC (now part of HP) & Sun did a lot of work on FC topologies like switched loops in addition to the original arbitrated loop and point-to-point.    

But bottom line, there was such an explosion of patents and advancements in late 80s/early 90s that what we know as fibre channel involved a large number of vendors.  

I'd love to see the link that said CERN invented it.  Unless the author referenced a specific patent or advancement, then it is wrong.

Oops.. Must have had a kangaroo loose in the top paddock when I wrote that. I stand corrected.
