Abstract
A technique consolidates data at multiple levels of granularity, the levels including a first level based on whole PLBs (physical large blocks) and a second level based on portions of donor PLBs. The technique further includes tracking PLBs in multiple PLB queues arranged based on storage utilization of the PLBs, and tracking PLB portions in multiple portion queues arranged based on storage utilization of the portions. When consolidating data to create a new PLB, a set of whole PLBs is selected, based on utilization, from the PLB queues, and a set of portions of donor PLBs is selected, based on utilization, from the portion queues. The selections are performed such that the total data size of the selected whole PLB(s) and the selected portion(s) fit within the new PLB.
