Abstract
Official abstract text for this publication.
Methods and apparatuses for updating members of a data storage reliability group are provided. In one exemplary method, a reliability group includes a data zone in a first storage node and a checksum zone in a second data storage node. The method includes updating a version counter associated with the data zone in response to destaging a data object from a staging area of the data zone to a store area of the data zone without synchronizing the destaging with the state of the checksum zone. The method further includes transmitting, from the data zone to the checksum zone, an update message indicating completion of the destaging of the data object, wherein the update message includes a current value of the version counter.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: updating a version indicator associated with a data zone of a first data storage node in response to destaging a data object from a staging area of the data zone to a store area of the data zone, wherein the destaging is not synchronized with a state of a checksum zone in a second data storage node; and transmitting, from the data zone to the checksum zone, an update message indicating completion of the destaging of the data object, wh…
