Abstract: Methods and structure for host-side device drivers for Redundant Array of Independent Disks (RAID) systems. One system includes a processor and memory of a host, which implement a device driver. The device driver receives an Input/Output (I/O) request from an Operating System (OS) of the host, translates Logical Block Addresses (LBAs) from the received request into physical addresses at multiple storage devices, generates child I/O requests directed to the physical addresses based on the received request, and accesses an address lock system at a RAID controller to determine whether the physical addresses are accessible. If the physical addresses are accessible, the device driver reserves the physical addresses by updating the address lock system, and directs the child I/O requests to a hardware path at the RAID controller for handling single-strip I/O requests. If the physical addresses are not accessible, the device driver delays processing of the child I/O requests.

Abstract: The disclosure is directed to a system and method for interleaving data utilizing a random access buffer that includes a plurality of independently accessible memory slots. The random access buffer is configured to store slices of incoming data sectors in free memory slots, where a free memory slot is identified by a status flag associated with a logical address of the free memory slot. Meanwhile, a label buffer is configured to store labels associated with the slices of the incoming data sectors in a sequence based upon an interleaving scheme. Media sectors including the interleaved data slices are read out from the memory slots of the random access buffer in order of the sequence of labels stored by the label buffer. As the media sectors are read out of the random access buffer, the corresponding memory slots are freed up for incoming slices of the next super-sector.
