Abstract: A method includes applying a write Input/Output (I/O) queue interval to a Logical Unit (LU) member of a consistency group (CG). The method also includes marking each write I/O with a timestamp and suspending I/O from the participating storage array to the LU member of the CG upon the participating storage array receiving a snapshot request from a master storage array. The method further includes determining whether the snapshot request timestamp is within the write I/O queue interval of the participating storage array.

Abstract: Methods and structure for reprogramming firmware in a storage controller using a virtual machine management (VMM) environment. A storage process (current firmware) in the storage controller operates in a current virtual machine (VM) under control of a hypervisor. Reprogrammed (new) firmware is loaded into a new virtual machine under control of the hypervisor. The new firmware initializes and directs the current firmware to quiesce its processing. The new firmware also requests the hypervisor to map data in the memory space of the current virtual machine into the memory space of the new virtual machine and to transfer ownership/control of devices and network addresses from the current virtual machine to the new virtual machine. The new firmware operating on the new virtual machine then takes control of the storage controller and resumes processing of requests.

Abstract: The present invention is directed to a method for completing a stripe write operation in a timely fashion to a RAID drive pool which includes an abnormally slow drive. For example, the stripe write operation either completes within a required time interval, or an error is provided to the host/initiator which provides an indication to an application that the stripe write operation did not complete.
