Embodiment Construction

[0021] Hereinafter, an example in which an embodiment of the present invention is applied to a storage device of an AV server used in a broadcasting station will be specifically described using the drawings. FIG. 1 is a block diagram showing the configuration of a storage section of an AV server to which an embodiment of the present invention is applied. The storage section 1 includes a FC (Fiber Channel) controller 2, a recording / reproduction processing system 3, a cache memory 4, an HDD controller 5, a CPU (Central Processing Unit) 6, a DRAM (Dynamic Random Access Memory) 7, and non-volatile Volatile SRAM (Static Random Access Memory)8. The recording / reproducing processing system 3 and the HDD controller 5 are connected using a bus 9 of the PCI (Peripheral Component Interconnect)-X standard.

[0022] In addition, 15 HDDs 10 (HDD10(1)-HDD10(15)) are included in the storage section 1 . Among these 15 HDD10, 10 HDD10(1)-HDD10(10) are used for AV data, 4 HDD10(11)-HDD10(14) ar...

Abstract

A data storage apparatus using a plurality of hard disk drives for storing stream data includes a command receiving portion for receiving a stream data read command from the outside; and a data processing portion reading the stream data stored in the hard disk drives upon receiving the read command, assembling the data, and transferring the assembled stream data to the outside. The apparatus further includes a control portion performing control of determining maximum time from receiving the read command to completing the assembly of the stream data, terminating the data read from the hard disk drives in the case where the maxim time has elapsed, and preparing the stream data transferred to the outside in the data processing portion only using data having been read; and a managing portion variably setting the maximum time according to a bit rate of the stream data read on the read command.

Description

technical field [0001] The present invention relates to a device using a HDD (Hard Disk Drive) for storing streaming data and a data reading method applied to the device. Background technique [0002] In recent years, an HDD array unit including several HDDs has been used in broadcasting stations and post-production in order to provide a large capacity for a storage device storing streaming data such as AV (Audio / Video) data. [0003] For example, such HDD array units are included in AV servers used as editing systems and broadcasting systems in broadcasting stations. The AV server has several AV data input / output ports, and transfers AV data at high speed between the input / output ports and the HDD array unit. [0004] Since the AV server needs to work continuously 24 hours a day and 365 days a year, and video and audio interruptions or delays are not allowed when playing programs, the AV server is required to have high working reliability and real-time responsiveness.
