Abstract: A point-in-time copy of data of a source volume stored in a first set of blocks of a plurality of storage devices is generated. A command to relocate the point-in-time copy from the first set of data blocks of the plurality of storage devices to a second set of data blocks of the plurality of storage devices of a target volume while bypassing the storage system controller is transmitted by a storage system controller. The command includes address information associated with the second set of blocks. A mapping data structure is updated to associate read requests for the point-in-time copy with the second set of blocks of the target volume.

Abstract: A command to relocate data from a first set of data blocks at the plurality of storage devices to a second set of data blocks while bypassing the storage controller is transmitted by the storage controller. The command includes address information associated with the second set of blocks to store the relocated data.

Abstract: A method of tracking flash memory in a storage system is provided. The method includes initializing a bad blocks threshold value and marking one or more planes or logical unit numbers (LUNs) of flash memory as bad, responsive to determining that bad blocks in the one or more planes or LUNs meet the bad blocks threshold value. The method includes adjusting the bad blocks threshold value, responsive to exceeding a threshold number or rate of retiring planes or LUNs of flash memory, and repeating the marking and the adjusting, with the bad blocks threshold value capped at a maximum threshold value.

Abstract: Dynamically managing protection groups, including: identifying a protection group of storage resources, the protection group associated with a protection group management schedule that identifies one or more protection group management operations to be performed; detecting a membership change in the protection group; and updating, in dependence upon the change in the protection group, the protection group management schedule.

Abstract: A command to relocate data is transmitted by a storage controller. The command includes first address information associated with a first set of blocks storing the data at one or more storage devices using a first programming mode and second address information associated with a second set of blocks at the one or more storage devices to store the relocated data using a second programming mode. The command causes the relocation of the data from the first set of blocks to the second set of blocks while bypassing sending the data to the storage controller. An acknowledgement is received that the relocated data has been stored at the second number of blocks.

Abstract: Dynamically managing protection groups, including: identifying a protection group of storage resources, the protection group associated with a protection group management schedule that identifies one or more protection group management operations to be performed; detecting a membership change in the protection group; and updating, in dependence upon the change in the protection group, the protection group management schedule.

Abstract: A system and method, which may be an offline method, extracts relevant image features about listing items in a network-based publication system for enabling image similarity searching of such listing items. When a seller lists an item, an image of the item is uploaded and may be sent to a picture processing service, which generates several digests. The digests are compressed data structures each representing a particular image feature such as edge, color, texture, or words. These digests are then stored in a search database, where the digests can be used to retrieve listings by image similarity at scale. A similar process can be performed for a query listing for searching the search database for items similar to the query listing.
