Chained, scalable storage devices

A chained, scalable storage system comprising:

• a plurality of storage devices, at least one of the storage devices a primary agent for one or more of the plurality of storage devices;
• a host device coupled via a host interface network to the at least one primary agent,
• wherein the at least one primary agent is configured to:
• receive a host request from the host device, the request to access a logical address of the one or more of the plurality of storage devices;
• determine, based on the logical address, a corresponding physical address in at least one of the one or more of the plurality of storage devices;
• generate, based on the physical address, a sub-request corresponding to the host request and each of the determined corresponding physical addresses in at least one of the one or more of the plurality of storage devices;
• send, via a storage device interface network operable independently of the host device, the sub-requests to the at least one storage device, the storage device interface network a peer-to-peer network coupling the storage devices to the primary agent;
• and
• receive, from the at least one storage device, respective sub-statuses in response to the sub-requests, determine an overall status based on each respective sub-status, and provide the overall status to the host device,
• wherein the host device is coupled to the one or more storage devices without employing a network switch.

A non-transitory machine-readable medium, having encoded thereon program code, wherein, when the program code is executed by a machine, the machine implements a method of accessing data in a chained, scalable storage system, the method comprising:

• receiving, by a primary agent of one or more storage devices, a host request from a host device coupled to the primary agent via a host interface network, the request to access a logical address of the one or more storage devices;
• determining, by the primary agent based on the logical address, a corresponding physical address in at least one of the one or more storage devices;
• generating, by the primary agent based on the physical address, a sub-request corresponding to the host request and each of the determined corresponding physical addresses in at least one of the one or more storage devices;
• sending, by the primary agent via a storage device interface network operable independently of the host device, the sub-requests to the at least one storage device, the storage device interface network a peer-to-peer network coupling the storage devices to the primary agent;
• and
• receiving, by the primary agent from the at least one storage device, respective sub-statuses in response to the sub-requests, determining an overall status based on each respective sub-status, and providing the overall status to the host device,
• wherein the host device is coupled to the one or more storage devices without employing a network switch.
