Embodiment Construction

[0031] Next, an embodiment in which the present invention is applied to an AV server used as a non-linear editing system in a broadcasting station is explained in detail using the drawings. figure 1 is a block diagram schematically showing the configuration of an AV server to which the present invention is applied. The AV server includes an input / output processor 1 and a storage unit.

[0032] The input / output processor 1 has a plurality of (for example, six) input / output ports, and performs input and output of AV data with an external device in SDI (Serial Digital Interface) or other synchronous transmission format or in an asynchronous transmission format.

[0033] The input / output processor 1 encodes (compresses) AV data input from the input / output port according to a predetermined encoding method, and transmits the data to the storage unit through the fiber channel 3 . The input / output processor 1 also decodes (expands) data transmitted from the storage unit through the ...

Abstract

A data storage apparatus and data storage method thereof which enable reduction of the number of maintenance sessions to replace malfunctioning storage means are provided. The data storage apparatus has a plurality of data HDDs; a plurality of error correction HDDs; a data distribution and error code generation device, which distributes and records input data in the data HDDs, and which generates error correction codes from the data according to the number of error correction HDDs and records the error correction codes in the error correction HDDs; and a data restoration device, which restores the data within HDDs in which a malfunction or response delay has occurred, using data and error correction codes read from the remaining HDDs.

Description

technical field [0001] The present invention relates to a data storage device suitable for application to, for example, HDD array units and a data storage method thereof. Background technique [0002] In recent years, HDD (Hard Disk Drive) array units have been frequently used to store AV (Audio / Video) data in broadcasting stations and post-processing. In the HDD array unit, a plurality of HDDs are installed into a single unit in order to realize both large-capacity storage and high data transfer rate. [0003] For example, huge storage capacity, high reliability, and high data transfer rate are required for AV servers used as nonlinear editing systems in broadcasting stations, so HDD array units are used as storage. Such an AV server has a plurality of recording / reproducing ports each of which inputs and outputs data streams at a high bit rate during operation. The requirements placed on the AV server include: (1) absolute reliability in preventing video or audio streamin...
