Only way that works if if they picked RAID 10.

But I know they picked RAID 10. ;-)

I don't like the way they described this though. They should have said "10 Drives with RAID-10 with 2 hot spares." Since RAID-10 is mostly Mirroring, just done at the adapter level, 10 drives means 2 hot spares. In theory you could just get 9 and save a buck but have a bit less safety margin if a drive fails.

We received a quote from our business partner for a new system that includes
the following:

(10) 283 GB 15K Spinning Disk Drives in two 4 x 4 RAID Arrays w/Hot Spares

* 1.132 TB Useable

I know what we asked for, but my question to you folks is "how would you
interpret this RAID configuration?"

We asked the BP, but the answer was not informative.
