NETWORK FAILOVER HANDLING IN MODULAR SWITCHED FABRIC BASED DATA STORAGE SYSTEMS

摘要

Systems, methods, apparatuses, and software for data storage systems are provided herein. In one example, a data storage system is provided that includes a first processor configured to establish a network connection with an external system, and receive first storage operations transferred by the external system over the network connection, the first storage operations related to storage and retrieval of data on at least one storage drive. The first processor is configured to transfer information describing the network connection for delivery to at least a second processor. The second processor is configured to identify when the first processor has failed, responsively establish the network connection with the external system based at least on the information describing the network connection, and receive second storage operations transferred by the external system over the network connection.

1. A data storage system, comprising:
a plurality of storage drives each configured to store data and retrieve the data stored on associated storage media responsive to storage operations; a first processor configured to establish a network connection with an external system, and receive first storage operations transferred by the external system over the network connection, the first storage operations related to storage and retrieval of data on at least one of the plurality of storage drives; the first processor configured to transfer information describing the network connection for delivery to at least a second processor; and the second processor configured to identify when the first processor has failed, responsively establish the network connection with the external system based at least on the information describing the network connection, and receive second storage operations transferred by the external system over the network connection, the second storage operations related to storage and retrieval of data on at least the one of the plurality of storage drives.
