Logical Drive Fault Tolerance.
This shows the fault tolerance mode of the logical drive.
To change the fault tolerance mode, run the Compaq EISA
Configuration Utility.
The following values are valid for the Logical Drive Fault
Tolerance:
None (2)
Fault tolerance is not enabled. If a physical drive reports
an error, the data cannot be recovered by the Compaq Drive
Array Controller.
Mirroring (3)
For each physical drive, there is a second physical drive
containing identical data. If a drive fails, the data can be
retrieved from the mirror drive.
Data Guard (4)
One of the physical drives is used as a data guard drive and
contains the exclusive OR of the data on the remaining drives.
If a failure is detected, the Compaq Fibre Channel Array
Controller rebuilds the data using the data guard information
plus information from the other drives.
Distributed Data Guard (5)
Distributed Data Guarding, sometimes referred to as RAID 5,
is similar to Data Guarding, but instead of storing the parity
information on one drive, the information is distributed across
all of the drives. If a failure is detected, the Compaq Drive
Array Controller rebuilds the data using the data guard
information from all the drives.
Advanced Data Guarding (7)
Advanced Data Guarding (RAID ADG) is the fault tolerance method
that provides the highest level of data protection. It
'stripes' data and parity across all the physical drives in the
configuration to ensure the uninterrupted availability of
uncorrupted data. This fault-tolerance method is similar to
distributed data guard (RAID 5) in that parity data is
distributed across all drives in the array, except in RAID ADG
the capacity of multiple drives is used to store parity data.
Assuming the capacity of 2 drives is used for parity data,
this allows continued operation despite simultaneous failure of
any 2 drives in the array, whereas RAID 4 and RAID 5 can only
sustain failure of a single drive.
