Passing hint of page allocation of thin provisioning with multiple virtual volumes fit to parallel data access
An information system comprises: a storage system including a processor, a memory, and a plurality of virtual volumes to be allocated pages from a storage pool of volumes; and a metadata server which, upon receiving from a client a write request containing file data to be written to a virtual volume in the storage system, returns the write request to the client with parallel information which is added to a data layout of the file data to be written in the virtual volume. The storage system, upon receiving the write request with the parallel information, allocates, based on the parallel information, pages from the storage pool to the virtual volume for writing the file data, so that the data layout is striped and the allocated pages fit striped data access according to the striped data layout.
