Scalable storage system having multiple storage channels

摘要

One example scalable storage system may include a first storage channel including a first storage node and a second storage node. The first storage node is coupled with the second storage node via a serial link. The scalable storage system may include a multi-channel interface including an input-channel coupled with the first storage node and an output-channel coupled with the second storage node. After receiving a request, the multi-channel interface may direct the request via the input-channel to the first storage node of the first storage channel. The first storage node may process the request. If a request segment in the request is directed to the second storage node, the serial link may transmit the request segment from the first storage node to the second storage node, allowing the second storage node to process the request segment.

1. A storage node configured to provide data storage in a scalable storage system, comprising:
a plurality of input-ports configured to receive data inputs from a multi-channel interface of the scalable storage system; a plurality of output-ports configured to transmit data outputs to the multi-channel interface of the scalable storage system; a bypass path coupled with one of the plurality of input-ports and one of the plurality of output-ports; a storage unit configured to utilize a solid-state storage device, wherein the data inputs and the data outputs are associated with data in the storage unit; and a data processor coupled with the plurality of input-ports, the plurality of output-ports, and the storage unit, wherein the data processor is configured to:
receive the data inputs via the plurality of input-ports,in response to a determination that the data inputs contain information relevant to the storage node, process the data inputs by access of the storage unit,in response to a determination that at least a segment in the data inputs contains information relevant to another storage node that is coupled with one of the plurality of output-ports via a serial link, transmit the segment as the data outputs to the another storage node via the one of the plurality of output-ports, andin response to a determination that the data inputs are not directed to the storage node, the data processor is configured to transmit the data inputs as the data outputs to the one of the plurality of output-ports via the bypass path.
