Abstract
A method for executing a write request in a clustered computing environment, comprising a plurality of computers connected in a network, including at least one client computer accessing data blocks stored on a first storage device of a shared aggregated pool of storage devices. Data blocks stored on the first storage device are linked to data blocks stored on at least one second storage device of the pool by error recovery data stored on a third storage device of the pool. When a client computer sends a write request to the first storage device for a new data block to be stored at an address on the first storage device, the new data block is written at the address on the first storage device. New error recovery data is calculated for the data block and is written to the third storage device.
