Abstract
A system that implements a data storage service may store data in multiple replicated partitions on respective storage nodes. The selection of the storage nodes (or storage devices thereof) on which to store the partition replicas may be performed by administrative components that are responsible for partition management and resource allocation for respective groups of storage nodes (e.g., based on a global view of resource capacity or usage), or the selection of particular storage devices of a storage node may be determined by the storage node itself (e.g., based on a local view of resource capacity or usage). Placement policies applied at the administrative layer or storage layer may be based on the percentage or amount of provisioned, reserved, or available storage or IOPS capacity on each storage device, and particular placements (or subsequent operations to move partition replicas) may result in an overall resource utilization that is well balanced.
