STORAGE DEVICE AND METHOD OF OPERATING THE SAME
Provided herein may be a storage device and a method of operating the same. A memory controller for controlling a memory device including a plurality of memory blocks having improved read performance may include a random read workload control, unit configured to control a state of a random read workload such that the random read workload is in any one of a set state and a clear state depending on a random read count obtained by counting a number of random read requests that are inputted from an external host; and a random read processing unit configured to retrieve a physical address corresponding to a logical address of the respective random read requests depending on the state of the random read workload.
Computing device with a separate processor provided with management functionality through a separate interface with the interface bus
A computing device includes a first processor; a second processor; a network interface communicably coupling the first and second processors to a network; an interface bus communicably coupling the first processor to the second processor; a first interface communicably coupling the second processor to the interface bus; a second interface communicably coupling the second processor to the interface bus, the second interface being separate from the first interface, wherein the second interface is configured to provide the second processor with management functionality over one or more hardware components of the computing device; and storage means communicably coupled to the second processor, wherein the second processor regulates access of the first processor to the storage means.
Data Collation Method, Storage Device, Storage Controller, and Storage Array
A data collation method in a storage array including reading first data from a first logical address without decompression, assigning, by a storage controller, a second logical address to the first data, storing the first data to the second logical address, establishing, by the storage controller, a mapping relationship between an address of a storage array and the second logical address, where the first logical address is mapped to a first physical address of a storage device, a length of the first physical address is equal to a length of first data, a length of the first logical address is equal to a length of second data, and the first data is compressed data of the second data, and receiving, by the storage controller, the first data from the storage device.
CAMERA SUPPORTING REMOVABLE STORAGE DIVIDED INTO MULTIPLE PARTITIONS
A camera that supports removable storage divided into multiple partitions is configured to write files to removable storage that is formatted into journaled and non-journaled partitions. The journaled partition uses a journaling file system and the non-journaled partition uses a non-journaling file system that is supported natively by an operating system, such as the operating system of a desktop computer. The non-journaled partition has stored on it computer program code executable by a processor to use the operating system to access files stored on the journaled partition. The camera may also be configured to partition the removable storage into the journaled and non-journaled partitions. The camera writes data to the journaled partition. This permits the processor to access the files stored on the journaled partition by the camera even if the operating system does not natively support the journaled partition.
System And Method For Synchronizing Caches After Reboot
A method and system for synchronizing caches after reboot are described. In a cached environment, a host server stores a cache counter associated with the cache, which can be stored in the cache itself or in another permanent storage device. When data blocks are written to the cache, metadata for each data block is also written to the cache. This metadata includes a block counter based on a value of the cache counter. After a number of data operations are performed in the cache, the value of the cache counter is updated. Then, each data block is selectively updated based on a comparison of the value of the cache counter with a value of the block counter in the metadata for the corresponding data block.
STORAGE DEVICE AND DATA PROCESSING SYSTEM INCLUDING THE SAME
A data processing system and method are disclosed. The data processing system may include a host, a storage device, and a battery supplying a power to the host and the storage device. The storage device may include a memory storing data received from the host, a cache temporarily storing the data, and a controller controlling the memory and the cache. The controller may be configured to receive a detachability attribute of the battery from the host, and determine, based on the detachability attribute of the battery, whether to perform a backup operation of the data in response to receiving a write command from the host.
System including a portable storage device equipped with a user proximity detector and method of preventing the loss thereof
A portable storage system. The portable storage system comprises a portable storage device having a flash memory element and a loss-prevention unit. The portable storage system further comprises Master and Slave proximity elements. One of the proximity elements is physically connected with the portable storage device, while the other is physically connected with the loss-prevention unit. The Master proximity element is configured to wirelessly determine the presence of the Slave proximity element within a predefined range.
Systems and methods for cache management for universal serial bus systems
A system includes a cache and a cache-management component. The cache includes a plurality of cache lines that correspond to a plurality of device endpoints. The cache-management component is configured to receive a transfer request block (TRB) for data transfer involving a device endpoint. In response to a determination that the cache both (i) does not include a cache line assigned to the device endpoint and (ii) does not include an empty cache line, the cache-management component assigns, to the device endpoint, a last cache line that includes a most recently received TRB in the cache, and stores the received TRB to the last cache line.
Adjustable power delivery scheme for universal serial bus
Described is an apparatus which comprises: an adjustable power supply source to generate an adjustable power supply; a node to provide the adjustable power supply to a device; and a bus which is operable to: send a first message to the device indicating that the adjustable power supply source is capable of dynamically providing an adjustable power supply; and receive a request from the device, the request indicating a new voltage or current specification.
Flash controller cache architecture
A buffer cache interposed between a non-volatile memory and a host may be partitioned into segments that may operate with different policies. Cache policies include write-through, write and read-look-ahead. Write-through and write back policies may improve speed. Read-look-ahead cache allows more efficient use of the bus between the buffer cache and non-volatile memory. A session command allows data to be maintained in volatile memory by guaranteeing against power loss.
