Parity set optimization for RAID 6 protection

 

RAID 6 IOAs provide optimal performance, capacity, and balance, so selecting any of the parity set optimizations will not affect the outcome of the parity sets performance.

 

Availability

A parity set optimized for availability offers a greater level of protection because it allows a parity set to remain functional in the event of a I/O bus failure. The parity set is formed from at least four disk units of equal capacity, with no more than two disk units attached to an individual bus on the IOA."
