Abstract: An apparatus having a memory and a controller is disclosed. The memory may have a write head and sectors in tracks. The controller may have a sector map and a translation map and may be configured to (i) receive a write command having a logical block address and a range value, (ii) examine the sector map to find a sector sequence (a) marked free, (b) about to reach the write head and (c) at least as long as the range value, (iii) write new data in the sector sequence, (iv) update the translation map to associate the logical block address of the write command with a physical address of the written sectors and (v) update the sector map according to the sectors written. Each entry in the sector map generally corresponds to a respective sector and indicates whether the respective sector contains valid data or is free.

Abstract: An apparatus may include a virtual flash device configured to emulate a flash memory device. The virtual flash device may include a flash interface configured to communicate with a flash controller, an address translation module configured to translate memory addresses from a flash based memory space to another memory space of another memory, a metadata and control module configured to manage metadata from the emulation of the flash memory device, and a non-flash memory controller configured to communicate with the other memory.

Abstract: A RAID storage management system includes a plurality of RAID storage devices and a controller configured to manage the plurality of RAID storage devices. The RAID storage management system also includes at least one expander operatively connected to the controller and operatively connected to the plurality of RAID storage devices. The expander is configured to receive a request from the controller for a RAID operation. The expander is also configured to, upon receiving the request, operate to assist the controller in performing the requested RAID operation.
