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.
The 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.
