Abstract: A method for using a block storage device for storing and reproducing electronic files is disclosed. The block storage device includes blocks, each one possessing a logical block address (LBA) unique to that block. The method includes providing a deduplication pathway, including a deduplication data structure (DDS), and a block indirection pathway, including a block indirection data structure (BIDS). When receiving an electronic file, if deduplication is desired for the electronic file, then processing the electronic file only through the deduplication pathway, and, otherwise, processing the electronic file only through the block indirection pathway.

Abstract: A method for recording parity data of data stripes within shingled media recording bands in a redundant array of independent disks can be accomplished using a plurality of shingled media recording (SMR) hard disk drives (HDD) each with a plurality of shingled data bands. A data stream received from a host computer system is sequentially stored to a plurality of block segments in successive order, one stripe at a time successively. Each of the shingled data bands possess n data blocks (or multiple data blocks that are grouped together as a data unit) that are successively ordered, each corresponding successive data block from all of the SMR HDDs defines a data stripe, accordingly n data blocks in each SMR HDD defines n stripes across the shingled data bands. A transaction group sync triggers a halt to writing the data stream. The rest of the data stripe is written with fill bits.

Abstract: Apparatus and associated method contemplating: operating a storage server having access to a plurality of storage devices, at least a first storage device of the plurality of storage devices defining a first bank and at least a second storage device of the plurality of storage devices defining a second bank; during a first time interval, energizing the first bank to enable data transfer, and de-energizing the second bank to disable data transfer; during the first time interval, mapping data received from the storage server to the first bank; during a second time interval that begins before a storage capacity of the first bank is full, de-energizing the first bank to disable data transfer, and energizing the second bank to enable data transfer; and during the second time interval, mapping the data received from the storage server to the second bank.
