Abstract: Provided are systems, methods, and apparatuses for managing memory. The method can include: establishing a connection via an interface, between a host device and a storage device; and transferring data, via the interface, between first memory associated with the host device and second memory associated with the storage device by performing a data operation on the second memory by an application executed by the host, where the storage device includes a processing element that accelerates the data operation by performing at least one offload function on the data operation.

Abstract: 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.

Abstract: A system and method for automatic deletion in a persistent storage device. In some embodiments, the method includes: receiving, by a persistent storage device, a first read command, for a first logical block of data; determining that a total number of read operations, for the first logical block of data, equals or exceeds a first threshold value; and in response to determining that the total number of read operations, for the first logical block of data, equals or exceeds the first threshold value, arranging for deletion of the first logical block of data from the persistent storage device.

Abstract: Systems and methods for processing storage transactions are disclosed. A transaction between a storage device and a host computing device is identified. The storage device determines that the transaction satisfies a criterion, and inserts data into a packet associated with the transaction. The data may be for identifying a memory subsystem of the host computing device. The storage device transmits the packet, including the data, to the host computing device for storing the packet in the memory subsystem based on the data.

Abstract: A system and method for differentiated storage services with a Ethernet SSD includes receiving, at an Ethernet SSD (eSSD), an input/output (I/O) service request from a remote host via a multiprotocol label switching (MPLS) network. The I/O service request includes at least one parameter that may be used to match the I/O service request to a label switched path (LSP) based on the parameter(s). A storage traffic stream may then be opened between the eSSD and the remote host over the MPLS network according to the LSP.

Abstract: An Ethernet solid-state drive (eSSD) system includes a plurality of eSSDs, an Ethernet switch and a baseboard management controller. The Ethernet switch is coupled to each of the eSSDs, and the baseboard management controller is coupled to the each of the eSSDs and to the Ethernet switch. The baseboard management controller controls the Ethernet switch to provide to each eSSD a corresponding predetermined bandwidth that is based on bandwidth information for the eSSD that is stored in a policy table of the baseboard management controller. The at least one predetermined bandwidth may include a predetermined ingress bandwidth and a predetermined egress bandwidth for the corresponding eSSD. The at least one predetermined bandwidth may be based on a service level associated with the corresponding eSSD, and may be adaptively based on operating parameters of the corresponding eSSD.
