Abstract
The techniques discussed herein identify failed segments of memory in a memory region. The techniques may then manage the failed segments of memory by logically clustering the failed segments of memory at an outlying portion of the memory region using a remapping process. The remapping process may include creating and storing remapping metadata defining segment remapping entries for the memory region. Accordingly, the failure clustering logically eliminates or reduces the memory fragmentation so that a system can allocate larger portions of contiguous memory for object storage.
