MULTI-FUNCTION FLEXIBLE COMPUTATIONAL STORAGE DEVICE
A multi-function device is disclosed. A first port may be used to communicate with a host processor. A second port may be used to communicate with a storage device. A third port may be used to communicate with a computational storage unit. Circuit may be used to route a message from the host processor to at least one of the storage device or the computational storage unit.
Controller for quality of service based arbitrations
A method and apparatus for operating a solid state drive is disclosed comprising receiving at least two commands from a host requiring an action by the solid state drive in a preliminary order, ordering the at least two commands based upon a quality of service classification for the at least two commands to a final order and executing the at least two commands on the solid state drive in the final order, wherein an operational parameter of the solid state drive is modified by at least one of the at least two commands.
STORAGE DEVICE, NONVOLATILE MEMORY SYSTEM INCLUDING MEMORY CONTROLLER, AND OPERATING METHOD OF THE STORAGE DEVICE
A nonvolatile memory system is disclosed. The nonvolatile memory system includes a host device and a storage device connected to the host device through a physical cable including a power line and a data line. The storage device includes: a nonvolatile memory; a link controller configured to temporarily deactivate the data line while supplying power from the host device through the power line; and a memory controller including a user verification circuit configured to authenticate a user of the storage device and change a state of the memory controller according to a verification result, a relink trigger circuit configured to control the link controller based on the state change of the memory controller, and a data processing circuit configured to encrypt and decrypt data.
Charge pump with wide current range
A charge pump has a first branch that includes a first node connected between a first pull-up switch and a first pull-down switch and a second branch that includes a second node connected between a second pull-up switch and a second pull-down switch. The second branch is connected in parallel with the first branch. The charge pump has a voltage equalization circuit to equalize a first voltage at the first node and a second voltage at the second node. A third branch includes a third node that is connected between a third pull-up switch and a third pull-down switch. The third node is connected to the second node. The third pull-up switch and the first pull-up switch are controlled by a common pull-up signal. The third pull-down switch and the first pull-down switch are controlled by a common pull-down signal.
System and method for securely connecting to a peripheral device
A device connectable between a host computer and a computer peripheral over a standard bus interface is disclosed, used to improve security, and to detect and prevent malware operation. Messages passing between the host computer and the computer peripherals are intercepted and analyzed based on pre-configured criteria, and legitimate messages transparently pass through the device, while suspected messages are blocked. The device communicates with the host computer and the computer peripheral using proprietary or industry standard protocol or bus, which may be based on a point-to-point serial communication such as USB or SATA. The messages may be stored in the device for future analysis, and may be blocked based on current or past analysis of the messages. The device may serve as a VPN client and securely communicate with a VPN server using the host Internet connection.
Server and method of identifying unsupported drives in a server
A method of identifying an unsupported storage device on a server is disclosed as including providing the server with a baseboard management controller (BMC), the BMC obtaining vital product data (VPD) from a storage device on the server, the BMC comparing the VPD from the storage device with one or more approved VPDs, and the BMC issuing an output in response to said comparison.
Randomized data distribution in highly parallel database management system
A massively parallel database management system includes an index store and a payload store including a set of storage systems of different temperatures. Both the index store and the storage system each include a list of clusters. Each cluster includes a set of nodes with storage devices forming a group of segments. Nodes and clusters are connected over high speed links. Each cluster receives data and splits the data into data rows based on a predetermined size. The data rows are randomly and evenly distributed between all nodes of the cluster.
Storage device, nonvolatile memory system including memory controller, and operating method of the storage device for independently performing a relink to a host device
A nonvolatile memory system is disclosed. The nonvolatile memory system includes a host device and a storage device connected to the host device through a physical cable including a power line and a data line. The storage device includes: a nonvolatile memory; a link controller configured to temporarily deactivate the data line while supplying power from the host device through the power line; and a memory controller including a user verification circuit configured to authenticate a user of the storage device and change a state of the memory controller according to a verification result, a relink trigger circuit configured to control the link controller based on the state change of the memory controller, and a data processing circuit configured to encrypt and decrypt data.
MEMORY SYSTEM AND INFORMATION PROCESSING SYSTEM
According to one embodiment, a memory system includes a nonvolatile memory and a memory controller configured to execute a patrol process, in response to a first command set from a host device. In the patrol process, the memory controller is configured to read first data from the nonvolatile memory, and not to output the first data to the host device.
KEY MANAGEMENT FOR SELF-ENCRYPTING DRIVES
An information handling system may include a processor; an encrypted storage resource, wherein the encrypted storage resource is coupled to the information handling system via a storage controller that does not implement locking and unlocking functionality for the encrypted storage resource; and a management controller configured to: receive a request to unlock the encrypted storage resource; determine an encryption key associated with the encrypted storage resource; and unlock the encrypted storage resource with the received encryption key via a sideband interface coupling the management controller to the encrypted storage resource.
