Abstract: A storage device with automatic-switching function is disclosed. When the storage device is coupled to a USB interface, the power provided by the USB interface turns the USB/SATA converter on to convert data from the USB interface into SATA format and transmit to a hard disk. When the storage device is coupled to a SATA interface instead of the USB interface, the power provided by the USB interface does not turn the USB/SATA converter on to convert data. In this way, the data from the SATA interface directly transmit to the hard disk.

The USB interface of the enclosure OA operates as a master and the USB interface of each of the plurality of servers acts as a slave to the enclosure OA, such that each of the server modules can be managed by the remote management system using a single communication address.

Abstract: Protecting computer systems from attacks that attempt to change USB topology and for ensuring that the system's information regarding USB topology is accurate is disclosed. A software model is defined that, together with secure USB hardware, provides an ability to define policies using which USB traffic can be properly monitored and controlled. The implemented policy provides control over USB commands through a combination of software evaluation and hardware programming. Legitimate commands are evaluated and “allowed” to be sent to a USB device by a host controller. Illegitimate commands are evaluated and blocked. Additionally, the USB topology is audited to verify that the system's topology map matches the actual USB topology.

Abstract: Mechanisms for adjusting direction of data flow between input/output (I/O) bridges and I/O hubs based on real time traffic levels are provided. The mechanisms of the illustrative embodiments provide firmware and/or hardware for monitoring data flow through an I/O bridge loop and corresponding I/O hub in order to determine if a condition exists requiring reassignment of the direction each I/O bridge sends its data. In particular, the firmware/hardware determines whether a current traffic condition through the I/O bridges and I/O hub meets criteria indicative of one pathway through the I/O bridge loop being over-utilized while another pathway through the I/O bridge loop is under-utilized. If it is determined that such a condition exists, the configuration of the I/O bridges may be automatically modified to reassign which pathway is utilized by the I/O bridge in sending/receiving I/O data traffic through the I/O bridge loop.

Abstract: A system and method for an efficient implementation of a software-managed cache is presented. When an application thread executes on a simple processor, the application thread uses a conditional data select instruction for eliminating a conditional branch instruction when accessing a software-managed cache. An application thread issues a conditional data select instruction (DMA transfer) after a cache directory lookup, wherein the size of the requested data is dependent upon the outcome of the cache directory lookup. When the cache directory lookup results in a cache hit, the application thread requests a transfer of zero bits of data, which results in a DMA controller (DMAC) performing a no-op instruction. When the cache directory lookup results in a cache miss, the application thread requests a data block transfer the size of a corresponding cache line.

Abstract: Auto-discrimination between FC and SATA devices upon insertion of a device into a port of a FAST-compatible switch is disclosed. Without user intervention, the port is able to determine the type of device attached, set the appropriate data rate in the Phy or SERDES and, in the case of FC or SATA drives, start the disk insertion process into the active switch zones. The SERDES is first initialized to FC speeds, and the receive path is searched for a receive signal. Upon detecting a receive signal, the detection circuitry then checks to see if a valid SATA Out Of Band (OOB) sequence is received. If a valid SATA OOB sequence is received, the SERDES is configured for SATA speeds and analog settings. If a valid SATA OOB sequence is not received, and instead a FC auto-negotiation process runs to completion, the SERDES remains at FC speeds.
