[Bei Jing Ji Intraoperative]
In in the past 20 years, parallel (Parallel) bus interface has occupied leading status on storage market.But along with the continuous lifting of processor frequencies and memory bandwidth, two kinds of main parallel bus interface technology: advanced techniques configuration (Advanced Technology Attachment ATA) and small computer system interface (Small Computer System Interface SCSI) show not enough next gradually.They are faced with an identical problem.Owing to adopt parallel interface, the bus of transmission data and signal is to overlap to use, so transfer rate can be subjected to certain restriction.If improve the speed of transmission, Chuan Shu data and signal tend to produce and disturb so, thereby lead to errors.
In this case, sequence (Serial) interfacing is just arisen at the historic moment.The sequential bus interface technology is not the improvement of concurrent technique, but a kind of brand-new bus architecture fully.Corresponding with advanced techniques configuration and small computer system interface is that serial advanced technology disposes (Serial Advanced TechnologyAttachment SATA) and two kinds of technology of serial connecting small computer system interface (Serial Attached SCSISAS), and they have overcome the deficiency in original parallel bus interface technology.In the process of data transmission, data line and signal wire independently use, and it is independent that the frequency of transmission also keeps, therefore compare with parallel bus interface technology in the past, the transfer rate of serial bus is 30 times that walk abreast, because above-mentioned advantage is so sequence type hard disk becomes main flow gradually on storage market at present.
Yet, though the application of sequence type hard disk is popularized gradually, but employed on the market at present hard disk adapting box mostly is ATA or scsi interface, still lacks a kind of hard disk adapting box that can be applicable to serial advanced technology configuration hard disk and serial connecting small computer system interface hard disk simultaneously.
Therefore, be necessary that in fact a kind of hard disk adapting box, this hard disk adapting box can use the demand of the hard disk adapting box of serial connecting small computer system interface and two kinds of interfaces of serial advanced technology configuration simultaneously.
[summary of the invention]
