COST-EFFECTIVE IAAS (INFRASTRUCTURE-AS-A-SERVICE) CLOUD STORAGE BASED ON ADAPTIVE VIRTUAL DISKS (AVD)

摘要

There are provided a system, a method and a computer program product for operating a cloud computing storage system. The cloud computing storage system allocates and manages virtual disks. A virtual disk provides a logical data storage. The cloud computing storage system divides data stored in the virtual disks into chunks and allocates the chunks to physical data storage devices. The cloud computing storage system monitors I/O access patterns and user requests to change data storage capacities and throughputs of the virtual disks in real time. The cloud computing storage system dynamically reconfigures an allocation of the chunks to the physical data storage devices.

1. A method for operating a cloud computing storage system, the method comprising:
allocating and managing virtual disks for one or more users, a virtual disk providing a logical data storage; dividing data stored in the virtual disks into chunks and allocating the chunks to physical data storage devices; monitoring I/O access patterns and user requests to change data storage capacities and throughputs of the virtual disks in real time; and dynamically reconfiguring an allocation of the chunks to the physical data storage devices.
