Abstract: Systems and methods of fast synchronization failure detection in distributed databases are disclosed. An example of a method includes receiving a digest of a database stored at a sending node in a network, the digest broadcast by the sending node to N number of nodes in the network. The method also includes generating a digest of a database stored at a receiving node in the network. The method also includes comparing the generated digest to the received digest. The method also includes issuing a lost synchronization signal by the receiving node when the comparison indicates a change in the database stored at the sending node.

Abstract: According to one embodiment, a server is automatically deployed using a pre-provisioned logical volume LV. A first world wide name WWN1 is associated 320 with a logical volume LV1 associated with a disk array controller 260. A second world wide name WWN1, which is assigned to a server S1, is received 335 at the disk array controller 260. If 340 the first world wide name WWN1 is the same as the second world wide name WWN1, the server S1 is enabled 350 to access the logical volume LV1. The first and second world wide names are not required to be assigned to any server S1, S2 at the time that the first world wide name is associated with the logical volume.

Abstract: A network device comprises a processor and storage coupled to the processor. The storage contains firmware that, when executed by the processor, causes the processor to implement a plurality of virtual devices. Each virtual device is configured to receive packets in a channel unique to such virtual device. The channels of the plurality of virtual devices are implemented on a single communication link. The network device is configured to receive a channel status message that is indicative of status of a channel corresponding to that message.

Abstract: A system and method are provided for interfacing a Fibre Channel network to an Ethernet based network. The method includes the operation of establishing a connection between a Fibre Channel device and an NPIV interface in an Ethernet interconnect module (210). Another operation is processing a fabric login from a server on the Ethernet based network, along with a server identifier that is sent to the Fibre Channel device (220). Acknowledgement frames for fabric login from the Fibre Channel device can be examined in order to identify the N_Port ID of the server (230). In another operation, the server's MAC address can be retrieved from a table using the N_Port ID (240). Then an Ethernet packet can be sent to the server using the server MAC address (250). The Ethernet packet contains a Fabric Provided MAC Address used to enable the server to communicate with the Fibre Channel device.

Abstract: Embodiments of the present invention are directed to providing configurable transmission rates for devices within a multi-device enclosure, despite common communication media within the multi-device enclosure that would otherwise constrain or fix the transmission rates of the devices. In one embodiment of the present invention, implemented within a virtual-connect manager or other module or device contained in, or associated with, a multi-server enclosure, the virtual-connect manager provides an administrative or management interface through which each server can be assigned a maximum transmission rate. The virtual-connect manager then continuously monitors the transmission rates of servers and/or ports within servers in order to apply back pressure, or flow control, so that the servers and/or ports within servers do not exceed the configured maximum transmission rates.

Abstract: A computer system has an aggregated plurality of hybrid network resources. The hybrid resources support both offloaded connections with a first set of clients and conventional connections with a second set of clients. The conventional and offloaded connections are established through a common physical connection to a network. A unique protocol address is assigned to each of two or more active ones of the resources. A virtual layer2 device is exported for each of the two or more active resources. The assigned protocol addresses are exposed to a protocol stack residing in the operating system of the computer system. Each of the assigned protocol addresses are exposed through and associated with the virtual device exported for the one of the active resources to which the protocol address is assigned. One or more of the conventional connections are established with the second set of clients through the active resources and their respective virtual devices.

The system is identified on the network by a global IP address and each of the plurality of nodes is identified by a unique local IP address. Each of the plurality of resources is uniquely identified by an assigned private IP address. At each of the processing nodes, a listening socket is created for each instance of the plurality of applications running on the node.

Abstract: A computer system aggregates a plurality of network resources of a computer system. The plurality of network resources forms a bypass stack operable to provide offloaded connections to one or more applications available on the computer system. Each of the applications is associated with a first port number. The computer system itself is addressable on the network by a public IP address. The system assigns private IP addresses to uniquely identify each of the plurality of network resources. The system creates a socket for each application by which the application can communicate with the network. The socket is associated with a first endpoint tuple that includes the public IP address and the first port number associated with the application for which the socket is created. The socket is further associated with a set of bypass endpoint tuples that are translated from the first endpoint tuple, each of the set including a different one of the private IP addresses.

Abstract: A new deflection structure (12) which deflects a beam of charged particles, uch as an electron beam (15), includes a serpentine set (20) for transmitting a deflection field, and a shielding frame (25) for housing the serpentine set (20). The serpentine set (20) includes a vertical serpentine deflection element (22) and a horizontal serpentine deflection element (24).

The shielding frame (25) includes a plurality of ground blocks (26, 28, 30, 32), and forms an internal serpentine trough (77) within these ground blocks, for housing the serpentine set (20).

The serpentine signal conductor (12) is supported at its ends by coaxial feed through connectors 28. A beam interaction trough (22) intersects the channel groove (46) to form a plurality of beam interaction regions (56) wherein an electron beam (54) may be deflected relative to the serpentine signal conductor (12).

Preferably, the resistive load comprises a carbon film on a surface of an end plug in one end of the bore.

Abstract: Various embodiments of a helical coil deflection structure of a CRT are described and illustrated which provide shielding between adjacent turns of the coil on either three or four sides of each turn in the coil. Threaded members formed with either male or female threads and having the same pitch as the deflection coil are utilized for shielding the deflection coil with each turn of the helical coil placed between adjacent threads which act to shield each coil turn from adjacent turns and to confine the field generated by the coil to prevent or inhibit cross-coupling between adjacent turns of the coil to thereby prevent generation of fast fields which might otherwise deflect the beam out of time synchronization with the electron beam pulse.

Front-end logic is disclosed which switches a single current switch (e.g. transistor) between a data input and an output of the front-end logic. Thus, a single current switch of delay is added to normal operation of a standard shift register modified to be reconfigurable.

Abstract: Light is modulated by an optical code member having first and second parallel tracks, each with alternate segments of different optical characteristics, such as optical reflectivity. The different segments are staggered between the parallel tracks. The modulated light is transmitted along first and second fiber optic elements from the first and second tracks to respective first and second photoelectric sensors having a common substrate to produce push-pull electrical outputs from said sensors. The light may be supplied to the first and second tracks by respective third and fourth fiber optic elements, which may extend from a common light source. The third and fourth fiber optic elements may have light supplying ends which are closely adjacent the light receiving ends of the first and second fiber optic elements.
