Virtual disk drive system and method

Defining size of a logical block or disk storage block such that disk space of a RAID subsystem forms a page pool of storage or a matrix of disk storage blocks

Writing data and allocating the data in the page pool of storage or the matrix of the disk storage blocks

Determining occupancy rate of the disk space of the RAID subsystem based on historical occupancy rate of the disk space of the RAID subsystem

Determining whether an additional disk drive is required. If so, a notification is sent to the RAID subsystem, then to the user

DEFINING A DEFAULT SIZE OF A LOGICAL BLOCK OR DISK STORAGE BLOCK SUCH THAT DISK SPACE OF A RAID SUBSYSTEM FORMS A PAGE POOL OF STORAGE OR A MATRIX OF DISK STORAGE BLOCKS

AUTOMATICALLY GENERATING A SNAPSHOT OF VOLUMES OF THE PAGE POOL OR A SNAPSHOT OF THE MATRIX OF DISK STORAGE BLOCKS AT PREDETERMINED TIME INTERVALS

STORING AN ADDRESS INDEX OF THE SNAPSHOT OR DELTA IN THE PAGE POOL OF STORAGE OR THE MATRIX OF THE DISK STORAGE BLOCKS SUCH THAT THE SNAPSHOT OR DELTA OF THE MATRIX OF THE DISK STORAGE

BLOCKS CAN BE INSTANTLY LOCATED VIA THE STORED ADDRESS
