Abstract
An apparatus includes a plurality of drives configured as a redundant array of independent disks (RAID) and drive array controller logic to: calculate a first partial parity log (PPL) value for a first write operation that targets a first active stripe of the plurality of drives; store the first PPL value in a first pre-allocated portion of the plurality of drives that depends on a first number associated with the first active stripe; calculate a second PPL value for a second write operation that targets a second active stripe of the plurality of drives; and store the second PPL value in a second pre-allocated portion of the plurality of drives that depends on a second number associated with the second active stripe.
