Veritas 5U84 Primary Storage Shelf RAID controllers
The Veritas 5U84 Primary Storage Shelf uses dual, hot swappable Fibre Channel RAID controllers. These controllers create and manage the 5U84 Primary Storage Shelf disk drive RAID sets that contain backed up data. They also create and manage the RAID sets on 5U84 Expansion Storage Shelves when those are attached to the 5U84 Primary Storage Shelf.
The Fibre Channel RAID controllers run RAID levels 6 and 10 on the storage shelf. RAID 10 is also referred to as RAID 1+0. RAID 6 offers the highest level of data 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 SAS-3 port. The SAS-3 port enables data to flow at SAS-3 data transfer rates between the 5U84 Primary Storage Shelf and the first optional 5U84 Expansion Storage Shelf.
