A network attached storage device coupled to a local network and including a network interface configured to receive digital content from a remote content provider outside the local network. The network attached storage device includes storage having a first region accessible by a user of the local network and a secure region. The network attached storage device includes a processor coupled to the storage, the processor configured to control access to the secure region of the storage based on instructions received from a remote content provider.

Secure stream buffer on network attached storage

A data storage system including a data storage device located on a first network and configured to download data from a network site based on universal resource locator ('URL') information of the network site, and an electronic device located on a second network different than the first network. The electronic device determines the URL information of the network site, receives user authentication data, receives a network address of the data storage device from a server using the user authentication data, and transmits the URL information to the data storage device using the network address of the data storage device. This causes the data storage device to download data from the network site contingent on correct user authentication being provided.

Retrieval of network site data with data storage device utilizing user authentication

An electronic device may be provisioned with an infrared (IR) light-emitting diode (LED) configured to externally transmit identifying information that particularly identifies the device, such as the device serial number, to outside of the device. A companion portable IR LED reader may be used to systematically scan a row or shelf or rack of electronic devices to read the respective communication signals transmitted from each of the respective devices, thereby enabling quick and accurate physical identification of the devices in a system/datacenter and inhibiting the unnecessary removal of an incorrect or misidentified device for replacement.

Electronic device having infrared light-emitting diode for data transmission

Systems and methods are disclosed for providing secure access to a data storage device. A user may move the data storage device (e.g., wave, twist, etc.). The data storage device may determine whether the motions valid and may allow access to the data storage device (e.g., to non-volatile memory of the data storage device) when the motions are valid.

Data storage device with secure access based on motions of the data storage device

Systems and methods are disclosed for providing secure access to a data storage device. A user may provide tap inputs, such as taps or knocks, on an enclosure of the data storage device. The data storage device may determine whether the tap inputs are valid and may allow access to the data storage device (e.g., to non-volatile memory of the data storage device) when the tap inputs are valid.

Data storage device with secure access based on tap inputs

A server chassis includes a plurality of microservers with each microserver including a Micro Baseboard Management Controller (&#x3bc;BMC) and at least one processor for controlling operation of the microserver. A BMC communication manager of the server chassis directly communicates with each &#x3bc;BMC of the plurality of micro-servers. A Chassis BMC (CBMC) connects to the BMC communication manager and communicates with the BMC communication manager via a plurality of communication protocols. The BMC communication manager translates at least one of the plurality of protocols to a different protocol for direct communication with each &#x3bc;BMC. According to one aspect, a &#x3bc;BMC is connected to an out-of-band port of a microserver for communicating with at least one processor of the microserver. According to another aspect, the BMC communication manager includes at least one CBMC connector for communicating with the CBMC, and a plurality of &#x3bc;BMC ports for communicating directly with a respective &#x3bc;BMC.

Baseboard management controllers for server chassis

A Chassis Baseboard Management Controller (CBMC) includes at least one memory for storing data related to a plurality of microservers in a server chassis. A request is received from a remote device for microserver hostnames to build a locality map for a storage or processing pool in a distributed storage or processing network. A device slot number corresponding to a physical location of the microserver in the server chassis is determined for each microserver. The determined device slot number is appended to a chassis hostname to create respective microserver hostnames. According to one aspect, a microserver hostname is received from a CBMC and stored in a memory of a &#x3bc;BMC of a microserver. The microserver hostname is retrieved from the memory by a processor of the microserver during a boot sequence. The retrieved microserver hostname is set as a hostname for communicating via at least one network interface.

Automatic hostname assignment for microservers

A data storage system including a data storage device located on a first network and configured to download data from a network site based on universal resource locator ('URL') information of the network site, and an electronic device located on a second network different than the first network. The electronic device can be configured to determine the URL information of the network site, determine a network address of the data storage device, and transmit the URL information to the data storage device using the network address of the data storage device, wherein receiving the URL information causes the data storage device to download data from the network site.

Data transfer by data storage device based on received uniform resource locator information

Systems and methods are disclosed for determining an input voltage level of an input voltage received by a connection cable. A monitoring component may determine whether the input voltage level matches one of a plurality of voltage levels. The connection cable may include an indicator component that may indicate which of the plurality of voltage levels matches the input voltage level.

Connection cable with voltage level indicator

A Data Storage Device (DSD) enclosure includes a chassis and at least one backplane mounted in the chassis. According to one aspect, each backplane includes a row of DSD slots and a switch slot located in a middle portion of the row of DSD slots. A plurality of signal traces connect the DSD slots to the switch slot.

Data storage device enclosure

A system is disclosed comprising a plurality of light emitting devices located along a path of travel, each light emitting device comprising a light emitting source, a sensor, a communication module, and a processor, wherein when a first one of the plurality of light emitting devices is activated, the processor in the first light emitting device is configured to detect one or more physical structures surrounding the first light emitting device, detect one or more other light emitting devices, and based at least in part on the detection of the one or more physical structures and the one or more other light emitting devices, determine a location of the first light emitting device with respect to the path of travel.

Autonomously operating light emitting devices providing detection and warning of hazardous condition on path of travel

A dual head extruder for a three-dimensional additive printer can be used to receive and dispense material. The extruder can include a number of different components including two nozzles, at least one having an adjustable opening configured to discharge material. The adjustable opening can be configured to be moved and rotated so as to align the adjustable opening with a plurality of paths along which the material is configured to be deposited for generating a three-dimensional object. The adjustable opening can comprise a first orifice and an obstruction member configured to move with respect to the first orifice. The position of the obstruction member can adjust the size of the opening area of the adjustable opening.
