摘要： 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.

摘要： 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.

摘要： 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.
