Abstract
Official abstract text for this publication.
A RAID data storage system incorporates permanently empty blocks into each stripe, distributed among all the data storage devices, to accelerate rebuild time by reducing the number of blocks that need to be rebuilt in the event of a failure.
First claim
Opening claim text (preview).
What is claimed is: 1. A data storage apparatus comprising: a processor; memory connected to the processor; a plurality of data storage devices connected to the processor, each of the plurality of data storage devices organized into a plurality of equally sized logical data blocks; and computer executable program code configured to execute on the processor, wherein: the plurality of data storage devices are organized into logical stripes such that one logical data block fro…
