Abstract: Systems, methods, apparatuses, and software for data storage systems are provided herein. In one example, a data storage system is provided that includes a processor and a network interface having a tunneled network connection established with another network interface associated with another processor. The processor is configured to receive one or more packets indicating the network interface as a network destination and comprising a storage operation, and inspect at least a storage address included in a header of the one or more packets to determine that the storage operation corresponds to a storage drive managed by the other processor. The processor is configured to establish one or more further packets comprising the storage operation and having a header modified from the one or more packets to indicate a network address of the other network interface, and transfer the one or more further packets for delivery to the other network interface.

Abstract: Systems, methods, apparatuses, and software for data storage systems are provided herein. In one example, a data storage platform includes one or more data storage modules each comprising storage drives coupled over a Peripheral Component Interconnect Express (PCIe) fabric with at least one processing module that receives storage operations directed to the one or more data storage modules over one or more network interfaces. The processing module is configured to assign service levels in a queue to the storage operations that are received over the one or more network interfaces. Based at least on the service levels, the processing module is configured to service the storage operations from the queue with the one or more data storage modules over the PCIe fabric.

Abstract: Systems, methods, apparatuses, and software for data storage systems are provided herein. In one example, a data storage platform includes data storage assemblies each comprising one or more storage drives that service data storage operations over associated storage interfaces. A control processor is coupled to ones of the data storage assemblies over at least two types of sideband communication interfaces different than the storage interfaces of the storage drives. During an initialization process for the one or more storage drives, the control processor configured to transfer initialization data to each of the data storage assemblies over a first type of sideband communication interface and transfer further initialization data to at least one of the data storage assemblies over a second type of sideband communication interface when the at least one of the data storage assemblies does not respond to the initialization data over the first type of sideband communication interface.
