Multi-port interposer architectures in data storage systems

Systems, methods, apparatuses, and architectures for storage interposers are provided herein. In one example, a storage interposer module includes Peripheral Component Interconnect Express (PCIe) switch circuitry receives storage operations over a host connector that are issued by one or more host systems and transfers the storage operations for storage by one or more storage devices over drive PCIe interfaces. The storage interposer module also includes a control module configured to monitor the storage operations in the PCIe switch circuitry via a control interface coupled between the PCIe switch circuitry and the interposer control module, and selectively direct delivery of each of the storage operations to corresponding storage areas among the one or more storage devices based at least on information monitored about the storage operations in the PCIe switch circuitry.
