A online storage strategy is a computer-based system designed for data storage, which usually relieves the host computer system from the means of determining the place of the stored data. Instead, the data is divided virtual storage system into prevents of predetermined sizes and stored in a memory signifies that is useful to the user.
The invention includes a storage area subsystem that is certainly coupled to the coordinator computer and comprises a control processor and some fast hard drive memory models. These equipment are capable of realising data in a similar vogue to adhesive tape drives. It will help the system to maximize the use of obtainable storage. It also comes with a rapid response time.
The storage system is able to do a number of computerized data back-up operations. Furthermore, it can carry out data decompression and recovery processing. Another memory program can be used to enhance the versatility with the system.
A controller detects changes in the status of the physical storage device and updates the status of corresponding virtual safe-keeping devices in the virtual storage space system. The controller also takes over the info managing functions from host pc.
The control processor markets the procedure of the host program stages plus the disk interface stages. The amount of interface periods is determined by the amount of data to get transferred. Yet , for present purposes, the number of program stages is certainly not relevant.
When the sponsor receives a request, that issues a control to the channel adapter. An answer indicates regardless of if the data stream is ready to receive info. If the info stream is ready to receive info, the control determines the place that the data ought to be stored.
