About Dual Data Redundancy

One unique (though rarely occurring) feature of RAID 10 is dual fault tolerance. In some cases, two drives can fail simultaneously and still maintain the integrity of data. There are six combinations in which two drives can fail. The FastTrak SX4300 or SX8300 card protects your data array in four of those cases. Assume the drives are configured as follows:

CH indicates channels on the FastTrak Controller card.

A/B indicates which striped pair the drive belongs to.

1/2 indicates which part of stripe data.

CH1

CH2

CH3

CH4

 

 

 

 

Drive A1

Drive A2

Drive B1

Drive B2

 

 

 

 

Under RAID 10, the array maintains data integrity if any 1, 2 combination survives.
