What's the use of External HBA

[Fastline]

Fibre Channel is a complex subject, and generally SOHO users don't need to use or know about it.

Fibre Channel is a full blown, extreme speed, (up to 64Gbit/ps, per channel), multi-path, multi-initiator storage networking protocol.

Trying to describe it in a paragraph means actual research to get the words right for those of us that know about FC, but not work on it regularly. So, that sentence is what I can say... but still had to look up the current top speed, (which is debatable).

Thanks. I'm getting there :)
