http://storusint.com/pdf/SCSI_vs_FC.pdf seems very helpful!
I have not surveyed the FC offerings for small servers, PCs, Laptops. While it might be SAN oriented, I see they are available in popular form factors:
FC hard drive price compare - Google Search
Seems a bit faster than the hottest SCSI, and maybe with simpler/cheaper controller, cabling, termination. Controller comes as a plug in or motherboard.
Since it fits into the SCSI configuration metaphor, it is not surprising that it inherits many configuration attributes from SCSI.
I wonder if FC has more latency and lower random performance than SCSI, with the serial access and optical encoding/decoding, not to mention higher contention if many/more devices are on a channel.

I would like to know if I can move the disks from a V240 chassis into a V440 chassis to use the increased resources (CPU & Memory) to boost performance. I know you can move disks between V210/240 chassis's, but I'm not sure if this would work between 240s & 440s. Any help would be much appreciated. (4 Replies)
