Abstract: A system for reading stored data may include one or more Ethernet drives and a controller, both configured to communicatively connect to a host device. The controller may receive a first read command from the host device, determine a first drive among the one or more Ethernet drives using the first read command and a mapping table, translate the first read command into a second read command, and send the second read command to the first drive. Responsive to receiving the second read command, the first drive may send a first remote data transfer instruction to the host device independent of the controller. The first remote data transfer instruction may include stored data read from the first drive to cause the host device to write the stored data read from the first drive to one or more memory buffers in the host device indicated by the second read command.

Abstract: Various implementations described herein relate to systems and methods for managing selective erasure in a Solid-State Drive (SSD) including receiving a selective erase command corresponding to erasing valid and invalid data mapped to a logical address and in response to receiving the selective erase command, erasing blocks in which one or more pages mapped to the logical address are located based on a mapping table that maps the logical address to the one or more pages. Both valid data and invalid data may be physically stored in one or more pages.

Abstract: A method of managing data storage using a management device that includes determining respective status information for a plurality of storage devices, and calculating, based on the status information, a respective cost for each of the plurality of storage devices using a cost function that includes one or more parameters including at least one of: a program/erase (P/E) parameter, a block error state parameter, a block error level parameter, and a workload parameter. The method further includes selecting a destination storage device of the plurality of storage devices based on at least some of the calculated costs, and writing data to the destination storage device.

Abstract: Various implementations described herein relate to systems and methods for providing data protection and recovery for drive failures, including receiving, by a storage device, a write request from a host operatively coupled to a storage device, and determining, by the storage device instead of the host, an XOR result by performing an XOR operation of new data and existing data. The new data is received from the host. The existing data is stored in the non-volatile storage.

Abstract: A method includes enabling, by a processor, a user to create indication of configuration of a virtual subsystem. The processor enables the user to create, in the indication of configuration of the virtual subsystem, indication of a namespace associated with one of storage devices, indication of a controller, indication of a host, and indication of connectivity between a controller and a namespace or between a host and a namespace. The processor enables the user to select the indicated controller and the indicated namespace, select the indicated host and the indicated controller, and create, in the indication of configuration of virtual subsystem, indication of connectivity between the controller and the namespace and indication of connectivity between the host and the controller. The processor implements the configuration of the virtual subsystem in an appliance to cause the appliance to provide the host with storage access to the namespace via the controller.

Abstract: A storage appliance includes a first SSD, a second SSD, and a controller. The controller is able to calculate a first utilization parameter of the first SSD and a second utilization parameter of the second SSD. If the first utilization parameter is less than a threshold and the second utilization parameter exceeds the threshold, the controller identifies a data range stored on the first SSD to be removed. The removal of the data range from the first SSD causes the first utilization parameter to exceed the threshold. The controller then migrates the data range from the first SSD to the second SSD.
