Question about cabling up a SATA RAID . . .

In setting up a SATA II RAID box, just how many cables must one run? One per
drive (?) - for a big external RAID that seems kind of messy . Isn't there a
way to setup an external SATA RAID with a single cable?



Anyone?

Depends on the RAID box and where the RAID controller is.

The keyword you're looking for is "multilane".

Actually the answer is in the question.

'an external SATA RAID' is by definition connected through a single
cable. That's why it is an 'external SATA RAID' in the first place.

But any RAID of some performance will have several cables (connections)
going to it because most buses are bandwidth limited to just a few drives
connected through them.
 
Your direct attached storage (DAS) options are external raid enclosures
with SATA-to-Fibre Channel,, SATA-to-SCSI, SATA-to-Firewire and
SATA-to-USB backplanes with RAID controllers built-in, plus a
corresponding non-raid host bus adapter/controller with external
connector on your machine. Otherwise, you could try an enclosure with
an eSATA infiniband/multilane backplane, plus a corresponding SATA raid
controller card with an eSATA infiniband/multilane connector. If you
choose the multilane option, checkout HighPoint's RocketRaid 2000
series SATA raid controllers.
