Abstract: A system and method for target driven peer-zoning (TDPZ) synchronization can include a principal member device and a switch. The principal member device can include to send an active peer zone list request to a switch. In an example, the principal member device can store a first TDPZ database version number and a first TDPZ zone list. In an example, the switch may send a response based on the active peer zone list request. In an example, the response can include a second TDPZ database version number and a second TDPZ zone list. The principal member device may compare the first TDPZ database version number to the second TDPZ database version number.

Abstract: In some examples, a system maintains, for a base storage structure and a collection of snapshots associated with the base storage structure, statistics relating to usage of storage space based on data of the base storage structure and the collection of snapshots. The system checks metadata of a first snapshot to determine validity of references in the metadata and a presence of any child of the first snapshot or a grandparent of the first snapshot. The system associates, based on the validity of the references in the metadata and the presence of any child or grandparent of the first snapshot, a hint with a metadata entry of a parent of the first snapshot to indicate that a metadata entry of the child or the grandparent is to be checked. The system updates, using the hint, the statistics relating to usage of storage space.
