摘要： Disclosed is a computer-implemented method in a storage controller of changing a preferred node from a first node to a second node, comprising: receiving a notification of a request to remove the first node; reporting ports on the first node as non-preferred instead of reporting them as preferred; reporting ports on the second node as preferred instead of reporting them as non-preferred; compiling a target port groups report for each of the first node and the second node; and raising an asymmetric access state changed unit attention notification.

摘要： A system and method for providing erasure code protection across multiple storage devices. A data switch in a storage system connects a plurality of storage devices to a remote host. Each storage device is also connected to a controller, e.g., a baseboard management controller. During normal operation, read and write commands from the remote host are sent to respective storage devices through the data switch. When a write command is executed, the storage device executing the command sends a copy of the data to the controller, which generates and stores erasure codes, e.g., on a storage device that is dedicated to the storage of erasure codes, and invisible to the remote host. When a device fails or is removed, the controller reconfigures the data switch to redirect all traffic addressed to the failed or absent storage device to the controller, and the controller responds to host commands in its stead.

摘要： A controller monitors access frequencies of address ranges mapped to a data storage array. Based on the monitoring, the controller identifies frequently accessed ones of the address ranges that have lower associated wear, for example, those that are read more often than written. In response to the identifying, the controller initiates copying of a dataset associated with the identified address ranges from the data storage array to a spare storage device while refraining from copying other data from the data storage array onto the spare storage device. The controller directs read input/output operations (IOPs) targeting the identified address ranges to be serviced by access to the spare storage device. In response to a failure of a failed storage device among the plurality of primary storage devices, the controller rebuilds contents of the failed storage device on the spare storage device in place of the dataset associated with the identified address ranges.

摘要： An information processing apparatus including a removable storage device for storing data includes a control unit that determines whether communication is possible with the storage device and, if communication with the storage device is determined not to be possible, prohibit data from being written to the storage device. When the information processing apparatus is started up, the control unit again determines whether communication is possible with the storage device to which the control unit prohibits data writing and permits data writing to the storage device if communication with the storage device is determined to be possible.

摘要： A method of operating an emulated electrically erasable (EEE) memory system includes entering a quick write mode for a predetermined amount of time, upon detection of imminent power loss of the EEE memory system. A first write request is received immediately subsequent to entering the quick write mode, where the first write request includes a first address of an emulated memory of the EEE memory system and associated first data to be written at the first address. A first new record is created in non-volatile memory of the EEE memory system during the quick write mode, where the first new record includes the first address, the associated first data, and a blank record status identifier. The first new record is updated to have a quick record status ID, in response to a determination that record data of the first new record passes verification.

摘要： According to one aspect, a method for performance optimization of read functions in a memory system includes receiving, at the memory system, a read request including a logical address of a target data. The memory system includes a primary memory and a back-up memory that mirrors the primary memory. The method also includes searching a fault monitor table for an entry corresponding to the received logical address. The fault monitor table includes a plurality of entries that indicate physical locations of identified memory failure events in the primary memory and the back-up memory. Based on locating an entry corresponding to the received logical address, the method further includes selecting one of the primary memory and the backup memory for retrieving the target data. The selection is based on contents of the fault monitor table.
