DATA CONFIGURATION AND MIGRATION IN A CLUSTER SYSTEM

摘要

A cluster system includes a plurality of computing nodes connected to a network. Each node is configured to access its own storage device, and to send and receive input/output (I/O) operations associated with its own storage device. Further, each node of the plurality of nodes may be configured to have a function of acting as a first node, which sends a first message to other nodes of the plurality of nodes. The first message may include configuration information indicative of a data placement of data on the plurality of nodes in the cluster system according to an event. Following receipt of the first message from the first node, each of the other nodes may be configured to determine, based at least in part on the configuration information, whether data stored on its own storage device is affected by the event.

1. A cluster system comprising:
a plurality of nodes connected to one or more networks, each of the plurality of nodes comprising one or more storage devices for storing data, wherein:
each of the plurality of nodes is configured to access its own one or more storage devices, and to send and receive input/output (I/O) operations associated with its own one or more storage devices;each of the plurality of nodes is configured to have a function of acting as a first node, which sends a first message to other nodes of the plurality of nodes, the first message including configuration information indicative of a data placement of data on the plurality of nodes in the cluster system according to an event; andeach of the other nodes, upon receiving the first message from a node acting as the first node, is configured to determine, based at least in part on the configuration information, whether data stored on its own one or more storage devices is affected by the event.
