    Abstract: A data mirroring control apparatus includes a command distributing unit configured to transmit a first write command to a plurality of mirroring storage devices, the first write command including an instruction for data requested by a host to be written; and a memory lock setting unit configured to set a memory lock on the data requested by the host to be written among data stored in a host memory and configured to release the memory lock on the data after the data with the memory lock is written to the plurality of mirroring storage devices.

    Abstract: Systems and methods for generating random address mapping in non-volatile memories using local and global interleaving are provided. One such method for generating a random address mapping for a non-volatile memory (NVM) involves identifying a number of bits (N) in a physical address space of the NVM, selecting G bit(s) of the N bits to be used for global interleaving, where G is less than N, determining a number of bits (N-G) to be used for local interleaving, mapping the G bit(s) using a mapping function for global interleaving, interleaving (N-G) bits using an interleaving function for local interleaving, and generating a combined mapping comprising the mapped G bit(s) and the interleaved (N-G) bits.

    Abstract: A computer-implemented method, carried out by one or more processors, for a modified asynchronous replication session. In an embodiment, the method comprises the steps of acquiring a lock on a volume configuration, where the lock prevents changes to the volume configuration between a first volume and a second volume at a remote site. Internal control block information is updated, where the update includes at least a volume serial number of the first volume matching a volume serial number of the second volume. Responsive to updating internal control block information, the acquired lock is released to allow changes to the volume configuration.
