STORAGE SYSTEM THAT INCLUDES A PLURALITY OF ROUTING CIRCUITS AND A PLURALITY OF NODE MODULES CONNECTED THERETO

摘要

A storage system includes a storage unit having routing circuits networked with each other, each of the routing circuits configured to route packets to node modules that are connected thereto, each of the node modules including nonvolatile memory, and connection units, each coupled with one or more of the routing circuits for communication therewith, and configured to access each of the node modules through one or more of the routing circuits. When a first connection unit transmits to a target node module a lock command to lock a memory region of the target node module for access thereto, and then a second connection unit transmits a write command to the target node module before the first connection unit transmits to the target node module an unlock command to unlock the memory region, the target node module is configured to return an error notice to the second connection unit.

1. A storage system, comprising:
a storage unit having a plurality of routing circuits networked with each other, each of the routing circuits configured to route packets to a plurality of node modules that are connected thereto, each of the node modules including nonvolatile memory; and a plurality of connection units, each coupled with one or more of the routing circuits for communication therewith, and configured to access each of the node modules through one or more of the routing circuits, wherein when a first connection unit transmits to a target node module a lock command to lock a memory region of the target node module for access thereto, and then a second connection unit transmits a write command to the target node module before the first connection unit transmits to the target node module an unlock command to unlock the memory region, the target node module is configured to return an error notice to the second connection unit.
