Hi Ed & list,
Actually, I did not mention any "implementation
differences" in the RAID paper, as I did not think it
added much value. At any rate, now that you have
asked, I shall try to deliver.
One of the differences that I allude to in my article,
is that RAID 10 or 1+0 is a striped device whose
segments (or stripe units) are mirrored (RAID 1). But,
when you compare one vendor's implementation to
another's, you may observe that the location and
placement of each RAID 1 segment may be different,
when compared to a RAID 1+0 device. This is purely
dependent on "vendor implementation", which is the
reason why I mention, that they are "functionally
equivalent", but may different in implementation.
Hope that helps,
Gaja
