Storage architecture for server flash and storage array operation

摘要

A storage architecture of a storage system environment has a storage connector interface configured to exchange data directly between flash storage devices on a server and a storage array of the environment so as to bypass main memory and a system bus of the server. According to one or more embodiments, the storage connnector interface includes control logic configured to implement the data exchange in accordance with one of a plurality of operational modes that deploy and synchronize the data on the flash storage devices and the storage array. Advantageously, the storage connector interface obviates latencies and bandwidth consumption associated with prior data exchanges over the main memory and bus, thereby enhancing storage architecture performance.
