Abstract
Systems and methods for information storage replication are presented. In one embodiment a storage flow control method includes receiving a memory operation indication; performing a pre-reserve allocation process before proceeding with the memory operation, wherein the pre-reserve allocation process includes converting available unallocated memory space to allocated memory space if there is sufficient available unallocated memory space to perform the memory operation; executing the memory operation if the pre-reserve allocation process returns an indication there is sufficient memory space allocated to perform the memory operation; and aborting the memory operation if the pre-reserve allocation process returns an indication there is sufficient memory space allocated to perform the memory operation. In one embodiment, the memory operation is a write operation. The memory operation can be a write operation.
