Perhaps a typo?

We built what we called a "plaid", in which we built RAID 5 arrays on Sun
A3500 (hardware RAID with cache) [think horizontal] and then striped across
the RAID LUNs with Veritas Volume Manager [think vertical].  The intent was
to have redundance =and= keep essentially all spindles involved in each I/O
(for performance).

This was to hold an Informix database, and we set the stripe size to match
a database page size.
