Fault Tolerance

Fault Tolerance
Keeps data available and server running while a failed drive is being replaced; several fault
tolerance configurations are supported including:
RAID 6 with ADG
RAID 6 with ADGRAID 6 with ADG
RAID 6 with ADG
(Advanced Data Guarding): This is the highest level of fault tolerance. It
allocates two sets of parity data across drives and allows simultaneous write operations. This level
of fault tolerance can withstand two simultaneous drive failures without downtime or data loss.
RAID 6+0
RAID 6+0RAID 6+0
RAID 6+0
: Supported with min of 8 drives, but would have 4 available. Target benefit is to split
RAID across the external boxes.
NOTE:

NOTE:
RAID 6, 6+0 can be enabled with either
256 MB cache, Battery kit and Smart Array Advanced Pack License key option upgrades
512 MB BBWC and Smart Array Advanced Pack License key option upgrades
RAID 5
RAID 5RAID 5
RAID 5
(Distributed Data Guarding): This allocates one set of parity data across drives and allows
simultaneous write operations. This level of fault tolerance can withstand a single drive failure
without downtime or data loss.

NOTE:
RAID 5 can be enabled with a minimum 256 MB cache
RAID 5+0
RAID 5+0RAID 5+0
RAID 5+0
: This is a RAID 0 array striped across 5 elements. Combines the straight block-level
striping of RAID 0 with the distributed parity of RAID 5.
RAID 1, 1+0
RAID 1, 1+0RAID 1, 1+0
RAID 1, 1+0
(Drive Mirroring): This allocates half of the drive array to data and the other half to
mirrored data, providing two copies of every file. It is a high-performance RAID.

Fault Recovery
Minimizes downtime, reconstructs data, and facilitates a quick recovery from drive failure
On-Line Spares: There is no limit to the number of spare drives that can be installed prior to drive
failure. If a failure occurs, recovery begins with an On-Line Spare and data is reconstructed
automatically.
DRAM ECC corrects against single bit data and address corruption.
Battery-backed write cache upgrade provides for up to three days of battery power for data cache
retention. The data backup duration could be extended anytime the server's auxiliary power is
available during system power down.
