Sue,
If my configuration has one of each pair on a different loop, then I would need 2 hot spares, correct.

I thought you needed a hot spare for each Raid set, or is that not
correct.
Minimum of 1 hot spare per adapter (SCSI and PCI-x SAS) or adapter pair (PCIe SAS adapters) for RAID5 protection.
Mirroring hot spare works differently and you could get by with just 1 drive designated as the hot spare for the whole ASP. I recommend 1 spare drive per loop to give best odds of maintaining loop level mirroring.
