protection. It allows simultaneous write operations, while also allocating two sets
of parity data across the drives that comprise the RAID 6 array.
RAID 10 uses mirroring and striping technology without the use of parity. It enables
the creation of large high performance disk groups for data storage purposes, while
also providing the fault tolerance protection that mirroring offers. RAID 10 is used
to protect the metadata that is stored on the storage shelves.
The Fibre Channel RAID controllers also provide one SAS3 port. The SAS3 port
enables data to flow at SAS3 data transfer rates between the 5U84 Primary Storage
Shelf and the first optional 5U84 Expansion Storage Shelf.
