Can someone remind me, is the C600 chipset "raid-1" an md-raid with
the intel metadata, or is it dm-raid compatible like other fakeraid
drivers, or something else?

The C600 series chipset is a SAS controller. Depending on the SKU of the
chipset the OROM/EFI driver will enable or disable RAID5. Otherwise the
OROM should at least support RAID0 and RAID1. It uses the external IMSM
metadata. That means you can have MDRAID manage the RAID volumes, and
the RAID0 and RAID1 can be managed with DMRAID as well. Although Intel
no longer supports DMRAID usage for its external metadata and recommends
using MDRAID for management.
