Method and apparatus for performing node information exchange management of all flash array server

An all flash array (AFA) server, comprising:

• multiple nodes, wherein each of a first node and a second node of the multiple nodes comprises:
• at least one processor, arranged to control operations of the any node under control of multiple program modules;
• and
• a plurality of storage devices, the plurality of storage devices comprising multiple groups of storage devices, for storing data for the AFA server;
• wherein:
• a real-time communications path is established between the first node and the second node, wherein at least one of the first node and the second node selectively performs node information exchanging by directly transmitting node information through the real-time communications path;
• a non-real-time communications path is established between the first node and the second node, wherein at least one of the first node and the second node selectively performs node information exchanging by storing node information into at least one storage unit on the non-real-time communications path;
• in response to malfunction of one of the real-time and the non-real-time communications paths, the AFA server utilizes a remaining communications path of the real-time and the non-real-time communications paths to exchange respective node information of the first and the second nodes, to control high availability (HA) architecture of the AFA server according to the respective node information of the first and second nodes, for continuously providing service to users;
• wherein the node information of the first node indicates a role and status of the first node in the HA architecture, and the node information of the second node indicates a role and status of the second node in the HA architecture.
