Determining priorities for cached objects to order the transfer of modifications of cached objects based on measured network bandwidth

摘要

Provided are a computer program product, system, and method for determining priorities for cached objects to order the transfer of modifications of cached objects based on measured network bandwidth. Objects are copied from a primary site to a secondary site to cache at the secondary site. The primary site includes a primary server and primary storage and the secondary site includes a secondary server and a secondary storage. Priorities are received from the secondary server for the objects at the secondary site based on determinations made by the secondary server with respect to the objects cached at the secondary storage. A determination is made of modifications to the objects at the primary storage that are cached at the secondary storage. The received priorities for the objects from the secondary server are used to control a transfer of the determined modifications to the objects to the secondary server.

主权项

1. A computer program product for caching objects, the computer program product comprising a non-transitory computer readable storage medium having computer readable program code embodied therein that executes to perform operations, the operations comprising:
copying objects from a primary site to a secondary site to cache at the secondary site, wherein the primary site includes a primary server and primary storage and wherein the secondary site includes a secondary server and a secondary storage, wherein the primary and secondary sites connect via a network; receiving, from the secondary server, priorities for the objects at the secondary site based on determinations made by the secondary server with respect to information related to the objects cached at the secondary storage by the secondary server; determining modifications to the objects at the primary storage that are cached at the secondary storage; and using the received priorities for the objects from the secondary server to control a transfer of the determined modifications to the objects to the secondary server.
