Abstract: Errors can be introduced when data is transferred over a link between two entities such as between a host and a memory. Link error protection schemes can be implemented to detect and correct errors that occur on the link to enhance transmission reliability. However, these benefits are not without costs since such protection schemes increase both latency and power consumption. In one or more aspects, it is proposed to dynamically adjust the level of link error protection applied to match any change in the operating environment. For example, likelihood of link errors strongly correlates with the link speed. If the link speed is increased, a greater level of link error protection can be applied to counteract the increase in the link errors. If the link speed is decreased, the level of protection can be decreased so that latency and power consumption penalties can be minimized.

Abstract: A process for reconstructing data stored on a failed storage drive in a RAID storage system involves performing a resilvering procedure on a first portion of the data for reconstruction and performing a recompaction procedure on the remaining portion of the data for reconstruction. Because the resilvering procedure rebuilds its data only on the replacement storage drive, but the recompaction procedure rebuilds its data on one or more, likely multiple, non-failed storage drives, the additional bandwidth provided by the non-failed drives is utilized to increase the speed of the overall data reconstruction. Determining how much of the data storage chunk processing to distribute to the resilvering and to the recompaction procedures may be based on the respective write workloads of the replacement and non-failed drives, as well as on the percentage of free storage space available from each of the chunks.
