Abstract

An integrating method for disk array system is suitable to constitute storage system of computer with universal boards or cards and dedicated high-speed master-slave communication interfaces. The link and coordination of its units are realized by means of hardware and software. Router is used to implement parallel or concurrent operations between strings. Other techniques used include high-speed master-slave communication interface design, array control, cache manage and system scheduling.

Description

A kind of disc matrix system integrating method

The present invention relates to computer realm, be specially adapted to a kind of system integration occasion of use a computer general integrated circuit board and the master and slave communication interface formation of specialized high-speed computing machine external memory system.

American David Patterson summed up achievement in the past in 1987, the theory of structure disk array has at first been proposed, and six kinds of array structures such as 0,1,3,4,5 have been defined, some manufacturers have carried out the practicability exploitation later on, make and designed several disk array cards, these array control cards all are to use special chip to constitute, and it is unfavorable for upgrading along with the renewal of the innovation of computer science and technology and Control Software version, has limited the reduction of self usage range and cost.

At the shortcoming that above-mentioned prior art exists, task of the present invention provides a kind of system integration method of disk array.

The present invention implements by following measure.It is a kind of general calculation machine plate that utilizes, card and special-purpose high speed master, constitute the integrated approach of disk array system from communication interface, it is main at a high speed, connect with the bus of main frame 1 from communication interface 2 one ends, the other end connects with the bus 11 of slave, articulate the ROM (read-only memory) 3 that deposits Basic Input or Output System (BIOS) on the bus 11, the central processing unit 4 of slave, be used to deposit the static random-access memory 5 of block data, test monitoring equipment 7, the routing designator 6 that is used for the work of console panel array, read-only optical disc 10 and a plurality of series controller 8, series controller 8 one ends connect with bus 11, other end serial connection storage device 9.Described routing designator 6 presets 15 by the scheduling Buffer of instruction decode 16 address translation 17, command queuing 18, device drives 19, Cache and constitutes, instruction stream 13 and data stream 14 are through instruction decode 16 and address translation 17, preset at Cache scheduling and Buffer under 15 the control and carry out command queuing, drive through device drives 19 forming devices and order.Described high speed master, from communication interface 2, it is by dual port RAM 31, GAL34, host data impact damper 29, host address code translator 30, slave data buffer 35 and slave addresses code translator 36 constitute, host data impact damper 29 1 ends connect with host bus 23, the other end connects with twoport 31, host address code translator 30 1 ends connect with the low order address of host bus 23, the other end connects with twoport 31, host data impact damper and host address code translator choose high address line 25 by host bus, 26,27 through 34 realizations, slave data buffer one end connects with twoport 31, the other end connects with slave bus 43, one end of slave addresses code translator 36 connects with twoport 31, the other end connects with the low order address 37 of slave bus, slave data buffer 35 and slave addresses code translator 36 choose high-order ground bit lines 38 by the slave bus, 39,40,41 finish through 34.

Advantage of the present invention is: (1) adopts the general-purpose computations machine board card, connects by bus and equipment polyphone, realizes scheduling by routing designator.Except that routing designator, can use multiple general integrated circuit board to be beneficial to absorb the computing machine results new technology, reach the purpose that improves quality parameter and reduce cost; (2) systemic-function can arbitrarily be expanded, and is not subjected to the restriction of dedicated devices; (3) can articulate the combination of disc driver or CD drive or multiple memory device; (4) system scale and system architecture flexible variable help forming the series of products that are fit to the different user requirement; (5) owner's communication interface adopts non-standard high speed two-port RAM and communications protocol to realize having high data rate.

Description of drawings is as follows:

Accompanying drawing 1 system integration schematic diagram

Accompanying drawing 2 routing designators

The master and slave communication interface of accompanying drawing 3 high speeds.
