Veritas 5U84 Primary Storage Shelf RAID controllers
The Veritas 5U84 Primary Storage Shelf uses dual, hot swappable SAS-3 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 SAS-3 RAID controllers run RAID level 6 on the storage shelf. 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.
The SAS-3 RAID controllers also provides an additional 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.
The following figure and table provides component details for the Veritas 5U84 Primary Storage Shelf SAS-3 RAID controller modules.

Table: Veritas 5U84 Primary Storage Shelf SAS-3 RAID Controller indicator LED details
LED | Description | Color | Definition |
|---|---|---|---|
1 | Hardware normal | Green | On - Controller module is functioning properly. Flashing - Part of sequence as Controller module comes online, on standby. Off - Controller module power is off, Controller module is offline, or Controller module has a fault condition |
2 | Hardware fault | Amber | On - Controller module hardware fault. Off -Controller module functioning properly. |
3 | Identify | Blue | On - Unit identification (UID) active. Off - Normal state, no query for UID active. |
4 | OK to remove | White | On - Ready for removal, the cache is clear. Off - Do not remove the Controller module, cache still contains unwritten data. |
5 | Cache Status | Green | On - Cache contains unwritten data, Controller module functioning properly. Fast flash (1s on, 1s off) - Cache is active, cache flush in progress Slow flash (3s on, 1s off) - Cache self-refresh in progress after cache flush Off - Cache is clear or System is coming online |
