The full set of choices are
disk, tape, multidisk, other
I feel that since resilient dcache is different to RAID 5/6 which I assume is "multidisk" and clearly not as unreliable (I hope) as a non redundant system "disk" and its not "tape" so maybe Manchester should be thought of as an "other" type SE.
I shall confirm this with Glue people, and get back to you all later.
