Embodiment Construction

[0016] A bit-based serial transmission cloud storage method, which is implemented by the following steps:

[0017] 1) Parallel writing of data: receive the K-bit parallel data stream from the data cache; take the bit as the division unit, convert the received K-bit parallel data stream into K 1-bit serial data streams; The converted K 1-bit serial data streams are simultaneously written into a storage medium array composed of K memories with interfaces supporting serial access;

[0018] 2) Serial readout of data: read out K 1-bit serial data streams from a storage medium array composed of K memories with interfaces supporting serial access; read out K 1-bit serial data streams The data stream is assembled into a K-bit parallel data stream; the assembled K-bit parallel data stream is sent to the data cache;

[0019] In the steps 1)-2), the computer bus width is assumed to be but not limited to 32, K=32×m+r, and m is the buffer depth of parallel / serial data stream conversion, a...

Abstract

The invention relates to the information storage technology, and specifically relates to a bit-based serial transmission cloud storage method and a device. The invention helps to solve problems of a conventional data storage medium array mode that bus competition of a plurality of memories cannot be fundamentally eliminated and that load imbalance is easily caused. The bit-based serial transmission cloud storage method is realized by the following steps: 1) parallel writing of data: with bit as a segmentation unit, transforming a received parallel data flow of K bits into K serial data flows of one bit; and 2) serial reading of data: assembling the K serial data flows of one bit that are read out into a parallel data flow of K bits. The device can be applied to data storage of a variety of storage medium arrays having ports that support serial access, and is especially applicable for mass data storage.

Description

technical field [0001] The invention relates to information storage technology, in particular to a bit-based serial transmission cloud storage method and device. Background technique [0002] The data storage modes of existing commercially available serial storage media array products (such as disk arrays, memory arrays, Flash arrays, RAM arrays, etc.) all adopt byte-based serial storage modes, such as SATA storage mode. The characteristics of the SATA storage medium array mode are: the parallel data sent by the computer bus is input to the RAID for processing, and the data unit is divided into bytes (Byte) or bit group (bit set) for RAID processing, and these data units are then processed. Encapsulated into a data byte cache, and finally converted into serial data and written to a storage medium array composed of multiple memories, and in one access cycle, only one single memory can be written / read data at a time operation, thus causing it to be unable to fundamentally eli...
