Abstract
Example apparatus, methods, and computers facilitate improving spatial locality of file system block allocations for related items. One example method includes accessing a block allocation request that is configured to control a computer to allocate a block of storage available on a storage device and, upon determining that the block allocation request includes a session key that identifies a session associated with a block reservation pool, controlling the computer to allocate a block of storage from the block reservation pool to satisfy the block allocation request rather than allocating a block of storage from generally available blocks of storage. The block reservation pool includes blocks of storage on the storage device that satisfy a spatial locality relationship determined by a pre-read technique associated with the storage device.
