Abstract: A system and method for efficient execution of I/O operations in a storage environment including receiving, by a storage controller, an incoming I/O operation that can be serviced by a storage device while at least one pending operation is to be processed using the storage device, determining, based on an analysis by the storage controller of an operational state of a storage system that includes the storage device, whether processing the at least one pending operation is more efficient than issuing an alternative operation to the storage device, and issuing, by the storage controller, one or more instructions to the storage device.

Abstract: An indication that a die of the solid-state storage device has been marked as likely to fail based on a number of failed input/output (I/O) operations performed on the die satisfying a threshold may be received by a storage system controller from a solid-state storage device. In response to receiving the indication, one or more remedial actions associated with the die of the solid-state storage device may be performed.

Abstract: A system, method, and product for flexible RAID layouts in a storage system, including: determining a reliability of an individual storage device of a plurality of storage devices, the individual storage device containing a plurality of portions of a Redundant Array of Independent Disks (RAID) stripe in a storage system, wherein the RAID stripe includes user data and inter-device parity data; detecting a change in the reliability of the individual storage device that contains the portion corresponding to the RAID stripe; and changing an amount of intra-device protection corresponding to the RAID stripe by decreasing, in the RAID stripe, an amount of space used to store the inter-device protection data.

Abstract: A system with storage memory and a processing device has a logical deletion to physical erasure time bound. The system dereferences data, responsive to a direction to delete the data. The system monitors physical blocks in storage memory for live data and the dereferenced data. The system cooperates garbage collection with monitoring the physical blocks, so that at least a physical block having the dereferenced data is garbage collected and erased within a logical deletion to physical erasure time bound.

Abstract: Projecting capacity utilization for snapshots includes identifying one or more data release patterns of a storage system; identifying a snapshot policy; and generating, based on the one or more data release patterns and the snapshot policy, an estimate of an impact of the snapshot policy on a capacity of the storage system.

Abstract: Prioritizing highly performant storage systems for servicing a synchronously replicated dataset: detecting a communication fault between two or more storage systems that are synchronously replicating a dataset; identifying a preferred storage system for winning mediation, including determining that the preferred storage system winning mediation would result in better performance than other storage systems winning mediation; and requesting, by the preferred storage system, mediation from a mediation target.

Abstract: A method for deleting a set of keys from a storage server is provided. The method includes generating a probabilistic data structure for a first set of keys and for each key in a second set of keys, determining whether a key of the second set of keys is found in the probabilistic data structure. The method includes identifying the key as a candidate for deletion if the key is not found in the probabilistic data structure. A system is also provided.

Abstract: A method of cache management, the method comprising: identifying, among a plurality of storage items, storage items having an access count above a first threshold to generate a set of storage items; identifying, among the set of storage items, storage items having an updated access count above a second threshold to generate a subset of storage items, wherein, for each storage item, the updated access count is dependent upon a number of accesses subsequent to generating the set of storage items; and adding the storage items of the subset of storage items to a cache.
