Abstract: One or more techniques and/or systems are disclosed for enabling communication between a SAS communication port of a SAS communication component and multiple storage devices. In a first example, a first SAS to SATA bridge chip and a second SAS to SATA bridge chip may be configured to route data from a SAS communication component to multiple storage devices. In a second example, a SAS to SATA bridge chip and a port multiplier may be configured to route data from a SAS communication component to multiple storage devices. In a third example, a four port SAS to SATA bridge comprising two SAS ports and two SATA ports may be configured to route data from a SAS communication component to multiple storage devices. Supporting two or more storage devices with a single SAS communication port allows storage enclosures to increase storage capacity, while decreasing cost per slot.

Abstract: A mass data storage system including a data storage device comprising block groups each comprising a plurality of data blocks determines when one of the block groups is faulty and the data storage device continues to operate as a partially failed data storage device with respect to the remaining block groups which are not faulty. A striped parity data storage device array comprises data storage devices capable of operating as partially failed data storage devices allows copying of data from the block groups not associated with determined to be faulty of a partially failed data storage device to a spare data storage device which reduces the amount of data that must be rebuilt in the rebuild process, thereby reducing the amount of time the array spends in degraded mode exposed to a total loss of data caused by a subsequent data storage device failure.

Abstract: A storage management module for evaluating and repairing errors during monitoring or testing of storage devices of a storage system is described herein. When a storage device exhibits errors that reaches (in number) an error threshold, the storage management module determines whether any errors are due to damaged sectors localized in a single physical area of a predetermined size (referred to as a “patch”) of a platter of the storage device using the physical addresses of the errors. Two or more errors may be grouped as a single error if they are located within a predetermined threshold distance from each other on a platter and counted as a single error against the error threshold. A patch containing two or more damaged sectors is referred to as a “damaged” patch. In some embodiments, all sectors of a damaged patch (including undamaged sectors) are reassigned to spare sectors.

Abstract: Methods and apparatus for processing a seek request on a disk drive apparatus having a disk drive head is disclosed. The seek request is processed. During the seek request, the disk drive head is traversed across an actual distance. At least one expected seek time associated with the actual distance is obtained from a set of seek time data. One or more measurements are performed on the disk drive apparatus to obtain an update value. At least one expected seek time is then updated such that at least part of the update value is included in the at least one expected seek time.

Abstract: A mass data storage system including a hard disk drive comprising heads and platter surfaces determines when a head of the disk is faulty and the disk continues to operate as a partially failed disk with respect to the remaining heads which are not faulty. A striped parity disk array comprises disks capable of operating as partially failed disks allows copying of data from the platter surfaces not associated with a faulty head of a partially failed disk to a spare disk which reduces the amount of data that must be rebuilt in the rebuild process, thereby reducing the amount of time the array spends in degraded mode exposed to a total loss of data caused by a subsequent disk failure.
