A multiple function storage device is disclosed. The multiple function storage device may include an enclosure, a storage device associated with the enclosure, and an bridging device associated with the enclosure. The storage device may include a connector to receive a first message using a first protocol originating at a host, a physical function (PF) and a virtual function (VF) exposed by the storage device via the connector, storage for data relating to the first message, and a controller to manage writing a write data to the storage and reading a read data from the storage. The bridging device may include an embedded network interface controller (eNIC) to receive a second message using a second protocol from the host, a write buffer to store the write data to be written to the storage device by the host, a read buffer to store the read data to be read from the storage device for the host, a bridge circuit to translate the second message using the second protocol into the first message using the first protocol, and a root port to identify the storage device and to transmit the first message to the VF. The bridging device may be configured to map the host to the VF.

A method of reassembling a local disk manager (LDM) and array group (AGRP) includes starting a physical extent manager (PEM) configured to run on a number of nodes. The PEM on each node is configured to manage an AGRP running on the same node. A number of LDMs are reassembled, and each LDM is configured to manage virtual disks on each of the nodes. Once enough LDMs are reassembled, an AGRP can be reassembled.

A method includes adding new storage capacity to a data storage system, which has a pre-existing storage capacity. The method further includes rebalancing data from the pre-existing storage capacity to the new storage capacity in connection with a non-rebalancing operation performed on the pre-existing storage capacity.

A data transmission method and an apparatus used in a virtual switch technology are provided, and the method includes: receiving an IO request of a virtual machine VM for accessing a file or a disk, and When the IO request is to be sent to a physical NIC by using a user mode Open vSwitch (OVS), converting the IO request into an Internet Small Computer Systems Interface (iSCSI) command in a user mode, and then sending the iSCSI command to the user mode OVS, where the user mode OVS sends the iSCSI command to the physical NIC.

In one aspect, a computer-implemented method useful for migrating hundreds of Terabytes to Petabytes of data to a cloud-computing environment with a data transfer appliance includes the step of providing a data transfer appliance. The data transfer appliance includes an operating system, one or more computing processing units (CPU's), a memory, and a data storage system. The computer-implemented method includes the step of implementing data capture from a data storage system to the data transfer appliance. The computer-implemented method includes the step of storing the dedupe form of the data in the data transfer appliance by; providing a capture utility, wherein the capture utility comprises a data traversal engine and a data read engine.

According to one embodiment, while a memory card is in a second operation mode, a host controller monitors a reset signal for the second operation mode and detects that an error occurs in the second operation mode in the condition that a period of time during which both a card presence signal and the reset signal are asserted continues for a first period of time or longer. The host controller generates a first interrupt signal for starting a first driver in response to the detection of the occurrence of the error. The first driver, when started by the first interrupt signal, changes the operation mode of the memory card from the second operation mode to a first operation mode by controlling the host controller.

A hardware-implemented, pre-sequence execution checker is used to receive a set of firmware instructions that includes a suspend command, an intervening command, and a resume command, wherein the suspend command and the resume command are associated with suspending and resuming a same command, respectively; access a configurable conditions table that includes whether the suspend command and the resume command are supported by a storage media device; access state information that includes whether said same command has completed; and determine whether to perform or skip the suspend command based at least in part on the configurable conditions table and the state information. If it is determined to perform the suspend command, the suspend command and the intervening command are output. If it is determined to skip the suspend command, the intervening command is output.

A storage system includes a first storage device including a first write buffer and a first nonvolatile memory device, and a second storage device including a second write buffer and a second nonvolatile memory device. The first storage device is configured to, in response to a determination that a use buffer size of the first write buffer is greater than a first reference buffer size when the first storage device receives write data from a host, transfer the write data to the second storage device, and the second storage device is configured to store the write data.

A system and method for updating a configuration of a host system so that the memory sub-system of the host system emulates performance characteristics of a target memory sub-system. An example system determining a configuration of the host system, the host system comprising a memory sub-system; receiving, by a processing device, a request to emulate a characteristic of a target memory sub-system; analyzing a plurality of candidate configurations for the host system, wherein the plurality of candidate configurations comprises a candidate configuration that generates a load on the memory sub-system to decrease characteristics of the memory sub-system; and updating the configuration of the host system based on the plurality of candidate configurations, wherein the updated configuration changes the memory sub-system to emulate the characteristic of the target memory sub-system.

The present disclosure is directed to efficient memory activation at runtime. A memory module (e.g., a memory riser) being added to a device would typically cause the device to enter system management mode (SMM) to activate the memory module. However, activation (e.g., memory module initialization, hardware training and system reconfiguration) in SMM may substantially delay the resumption of normal operations. Consistent with the present disclosure, at least the memory module initialization and hardware training portions of the activation may be performed by an operating system (OS) in the device, allowing normal device operation to continue during the activation. The OS portion of the activation may generate configuration data. In at least one embodiment, the configuration data may be applied for use in SMM. For example, a system management interrupt (SMI) handler may apply the configuration data during a quiescent period (e.g., a period of inactivity) that occurs during SMM.
