A method for managing a cache memory network is disclosed. The method comprises estimating the popularity of a piece of data content according to an extreme learning machine, and managing the cache memory network according to the estimated popularity of the piece of data content. Estimation may be performed upon a request for the piece of data content, and may be accordingly cashed into an appropriate cache memory device upon estimation of its popularity.

A handheld communication device having an RF front end module has a switchable balun comprising a primary winding having a first two port winding and a second two port winding where a low noise amplifier is operatively coupled to the first and second two port windings and a power amplifier is operatively coupled to the first and second two port windings. A secondary winding is operatively coupled to an antenna, and a transceiver is operatively coupled to the low noise amplifier and the power amplifier. When the switchable balun is in a receive state, the antenna is operatively coupled to the transceiver through the low noise amplifier, and when the switchable balun is in a transmit state, the antenna is operatively coupled to the transceiver through the power amplifier. The ratio of the primary winding to the secondary winding is greater than a one-to-one ratio

摘要:
In at least some examples, a computer system includes a processor and a storage device coupled to the processor. The storage device stores a storage provisioning negotiation module that, when executed, causes the processor to determine whether a received storage provisioning request is approved. If the received storage provisioning request is not approved, the storage provisioning negotiation module causes the processor to determine a set of alternative storage provisioning options based on predetermined negotiation rules.
摘要:
Sets of power amplifier branches (which comprise an RF/microwave amplifier stage) are power combined within each stage and each set of power amplifier branches are biased in different classes of operation by bias circuits possessing different impedance characteristics such that the fundamental frequency components present at the output are in-phase with one another and the IMD3 components are anti-phase over a broad range of power levels. The RF input signal is provided by the output of the previous stage of the RF/microwave amplifier. The output of each stage is formed by power combining sets of these power amplifier branches, each of which are separately biased, so the fundamental components are additive resulting in the maximum possible output power and the IM3 components cancel partially or completely. IM3 reduction or cancellation can be achieved over a large range of output powers with the use of a feed forward control loop monitoring the input power and appropriately adjusting the bias currents and impedance characteristics of the bias circuits feeding the individual power amplifier branches in each stage of the RF/microwave amplifier.

The method includes querying for one or more logical unit numbers (LUNs) pertaining to a small computer system interface device, each LUN representing a potential path from a host to the SCSI device. Response data indicative of multiple LUNs to the single SCSI device is treated as separate instances of independent SCSI devices, with each separate instance representing a different SCSI separate instances of independent SCSI devices, with each separate instance representing a different SCSI device structure. A unique identifier (UID) is calculated for each SCSI device structure, from which a device file is generated based on the UID and contains UID and path information that differentiates between multiple paths from the host to the SCSI device.

The method and apparatus is utilized in order to generate a persistent path to a SCSI device for a host. In an embodiment, a SCSI device is queried for path information related thereto, and if path information is returned, a SCSI command requesting identifier data is issued to the SCSI device. The identifier data is used to determine a unique identifier (UID), from which is generated a UID-based device file for the SCSI device that is independent from the path information.

A method, by which a user mode application obtains all physical paths that point to a logical unit on a newly-discovered small computer system interface (SCSI) device, may include: sending an input output control command to a kernel component regarding future discovery of any SCSI device; awaiting discovery of a new SCSI device; awaiting generation, by the kernel component, of a unique identifier (UID) and at least one set of physical path information mapping thereto for a logical unit on the newly-discovered SCSI device; and receiving, from the kernel component, the UID and the at least one set of physical path information mapping thereto for the logical unit of the newly-discovered SCSI device.
摘要:
A method and arrangement, for use in a system having a host and one or more small computer system interface (SCSI) devices, are described for enabling a user application accessing the system to communicate with one or more of the SCSI devices. The method and arrangement serve to overcome a device node limitation observed in standard Linux, which limits the number of devices a user application may communicate with to 128 SCSI disk (sd) devices or 256 SCSI generic (sg) devices. The method and arrangement provide a pass through capability by allowing the user application to directly talk to any SCSI device by using virtual handles, thereby overcoming the device node limitation observed in standard Linux.
