A Virtual Storage area System With respect to Computer-Based Info Storage

A electronic storage product is a computer-based system for data storage, which in turn relieves the host computer system from the procedure for determining the location of the stored data. Instead, the data is definitely divided into hinders of established sizes and stored in a memory implies that is near the user.

The invention includes a storage subsystem that is coupled to the sponsor computer and comprises a control processor and a couple of fast disk memory sections. These contraptions are capable of agreeing to data in a similar trend to video tape drives. It will help the system to increase the use of offered storage. It also offers a rapid response time.

The storage space system can perform a number of automated data backup operations. Furthermore, it can accomplish data decompression and restoration processing. An external memory program can be used to boost the versatility of your system.

A controller picks up changes in the position of the physical storage device and updates the status of corresponding electronic storage area devices in the virtual storage space system. The controller also takes over the info internal rules management functions through the host laptop.

The control processor guides the procedure of the host program stages as well as the disk user interface stages. The number of interface levels is determined by the number of data to be transferred. Yet , for present purposes, the number of program stages is not relevant.

When the coordinate receives a request, this issues a command to the channel adapter. A response indicates whether or not the data stream is ready to receive info. If the info stream is ready to receive data, the control mechanism determines the place that the data must be stored.
