A digital storage product is a computer-based system with respect to data storage, which relieves the host computer from the technique of determining the positioning of the kept data. Instead, the data can be divided into hinders of predetermined sizes and stored in a memory signifies that is useful to the user.
The invention includes a safe-keeping subsystem that may be coupled to the web host computer and comprises a control cpu and some fast hard disk drive memory units. These systems are capable of accepting data in a similar manner to cassette drives. It will help the system to optimize the use of readily available storage. It also provides a rapid response time.
The storage area system is able to do a virtual storage system number of computerized data backup operations. Furthermore, it can perform data decompression and restoration processing. An external memory program can be used to improve the versatility within the system.
A controller detects changes in the position of the physical storage device and updates the status of corresponding virtual storage space devices in the virtual storage system. The controller likewise takes over the data management functions in the host pc.
The control processor guides the procedure of the host software stages as well as the disk program stages. The quantity of interface periods is determined by the number of data for being transferred. Yet , for present purposes, the number of program stages is usually not relevant.
When the sponsor receives a request, this issues a control to the funnel adapter. An answer indicates whether the data stream is ready to receive info. If the info stream is preparing to receive info, the control mechanism determines the place that the data ought to be stored.
