摘要： A storage device controller coupled to a storage device having a multiple locations for storing data coupled to may receive a WRITE ANYWHERE command including write data but not specifying a location of the storage device where the write data should be stored. The controller responds to the WRITE ANYWHERE command by selecting one or more unused locations of the storage device, and writing the write data in the one or more unused locations of the storage device. After writing the write data to the storage device, the controller may report where the write data is stored to the host. The host may also issue FREE commands to the controller specifying locations of the storage device which should be identified as unused. In response to a received FREE command, the controller may store information in a memory indicating that the location specified by the FREE command is unused.

摘要： A system may include mirroring logic, a controller, and first and second devices (e.g., data storage devices). The first and second devices may include multiple registers. The mirroring logic may be configured in a first mode wherein the mirroring logic allows the registers of the first device to be accessed from the controller and prevents the registers of the second device from being accessed from the controller. The mirroring logic may be configured in a second mode wherein the mirroring logic allows the registers of the second device to be accessed from the controller and prevents the registers of the first device from being accessed. The first and second devices may be configured via the mirroring logic such that the first and second devices are selected simultaneously. When selected simultaneously, the first and second devices may carry out a subsequently issued command substantially simultaneously.

摘要： A single field replaceable storage or computer system may include a processor coupled to a peripheral bus by a bridge device. The field replaceable unit (FRU) may also include system memory coupled to the processor and a network interface coupled to the peripheral bus. One or more drive controllers may also be included coupled to the peripheral bus. Additionally, the single field replaceable unit includes an array of disk drives coupled to the one or more drive controllers. The array of disk drives may be configured as one or more RAID logical volumes and exported or presented to client machines as one or more file systems through the network interface. The processor, system memory, network interface, drive controllers, and array of disk drives are all packaged together as a single field replaceable unit. The processor, system memory, network interface, drive controllers, and array of disk drives may be configured not to be individually field serviceable or replaceable. If the unit fails and needs servicing or replacement, the unit may be replaced as a whole.

摘要： A storage device controller configured for coupling to a storage device (e.g., a hard disk drive) having a multiple locations for storing data. The controller is coupled to receive a WRITE ANYWHERE command including write data. Unlike a conventional write command, the WRITE ANYWHERE command does not specify a location of the storage device where the write data is to be stored. The controller responds to the WRITE ANYWHERE command by: (i) selecting one or more unused locations of the storage device, and (ii) writing the write data to the storage device, wherein the writing of the write data includes directing the storage device to store the write data in the one or more unused locations of the storage device. At least a portion of the write data in stored in each of the one or more unused locations. The controller may be coupled to receive the WRITE ANYWHERE command from a host configured to track usage of the locations of the storage device. After writing the write data to the storage device, the controller may report the one or more locations of the storage device where the write data is stored to the host. The host may also issue FREE commands to the controller specifying locations of the storage device which should be identified as unused. In response to a received FREE command, the controller may store information in a memory indicating that the location of the storage device specified by the FREE command is unused.

摘要： A storage system may include a plurality of storage devices each having a plurality of addressable locations for storing data. A storage controller may be coupled to the storage devices and configured to store and retrieve data from the storage devices. An indirection map may be stored within the system having a plurality of map entries each configured to map a virtual address to a physical address on the storage devices. Each map entry may also store a checksum for data stored at the physical address indicated by the map entry. The storage controller may receive storage requests specifying a virtual address and may access the indirection map for each storage request to obtain the corresponding physical address and checksum. Dynamic striping may be employed so that new writes form new parity groups. Thus, stripes of various sizes may be supported by the storage system.

摘要： A storage system comprises a storage array controller and a storage array, which includes multiple storage devices and disk drive controllers. The storage array controller issues scrubbing operation commands to one or more of the disk drive controllers. In response, each disk drive controller that receives a scrubbing operation command reads data from within a data range from at least one of the disk drives, calculates a new checksum for the data, and compares the new checksum to a preexisting checksum for the data. If the new checksum doesn't equal the preexisting checksum, the data within the data range is determined to be erroneous.

摘要： Various embodiments of systems and methods for implementing a streaming I/O protocol are disclosed. In some embodiments, a method may involve: receiving a packet initiating a streaming write operation, where the packet indicates that the size of the streaming write is larger than the size of the packet; initiating a write access having a size larger than the size of the packet to a storage device; receiving subsequent packets included in the streaming write operation; and writing data received in the subsequent packets to the storage device as part of the write access initiated in response to the earlier packet. In some embodiments, streaming read operations may also be supported.
