Abstract: A technique for fastening a panel to an electronic cabinet frame involves inserting portions of rigid support members (e.g., rails) of the electronic cabinet frame into grooves defined by fasteners to attach the fasteners to the portions of the rigid support members of the electronic cabinet frame. The technique further involves positioning catches (e.g., latching members) of the panel adjacent catch members of the fasteners, and moving the panel toward the fasteners such that the catches of the panel engage with the catch members of the fasteners to fasten the panel to the electronic cabinet frame. Accordingly, no screws or other hardware is required to mount either the fasteners or the panel.

Abstract: The invention is directed to techniques which use a test circuit within an FPGA device to obtain a trace of a digital signal used by normal operating circuitry of the FPGA device. The test circuit stores the trace in memory of the FPGA device which is accessible without the need of a logic analyzer (e.g., accessible in a memory mapped or I/O mapped manner). Accordingly, the deficiencies of a conventional built-in approach (e.g., including a mounted connector and connections by sacrificing circuit board area) and soldering approach (e.g., soldering wires to the circuit board requiring time and effort, and increasing the likelihood of signal distortion) for logic analyzer access are avoided. One arrangement of the invention is directed to a computer system having a bus, a processor coupled to the bus, and an FPGA device coupled to the bus.

Abstract: The invention is directed to techniques for modifying a database. A database manager receives operation entries to be applied to a database. The database manager generates an error detection value for each operation entry as it is received, and enters both the operation entry and its associated error detection value in a journal. The database manager then copies the database to another version of the database, checks the validity of each operation entry using the error detection value, and, if the operation entry is valid, updates the copied version of the database based on the operation entry. The database manager also generates an error detection value for the database after it has been updated with all the operation entries from the journal. If there is a data corruption event, such as a power failure, then the database manager uses the error detection values for the operation entries and for the database during the database recovery process.

Abstract: A data storage system includes methods and apparatus that provide volumes for access by host computing devices. The volumes can have a storage size that is independently configurable from an actual amount of data storage that may or may not be associated with the volume. The volumes also have a persistent identifier. The volumes can have any amount of associated storage space allocated to the volume, including none, within the data storage system. Since the storage size and associated storage space are each independently configurable from each other, host that interface with the data storage system can perceive the volumes as being larger than they really are. A dynamic volume configuration technique is provided which allows storage space within storage devices in the data storage system to be dynamically associated and disassociated (i.e., added and removed) from the volumes on an as-needed basis, without requiring disruption of host activities with respect to the volumes.

Abstract: Techniques are provided for controlling a flow of packets in a data communications device. A first technique involves transferring packets of a particular packet flow based on an initial policy scheme, and planning a scheme change to change the initial policy scheme to a new policy scheme based on conditions within the data communications device existing while transferring the packets of the particular flow based on the initial policy scheme.

The change signal indicates that the data communications device has planned the scheme change. Additionally, the first technique involves processing the scheme change based on either a reply signal from, the source or an absence of a reply signal from the source.

Abstract: A server installation, which includes multiple servers, services a client request using a filter index that is different than a destination address associated with the client request. This enables clients to generate client requests for a server installation in a conventional manner without regard to whether a server installation is formed by one server or multiple servers. Accordingly, when a server installation is scaled by increasing the number of servers for redundancy, load distribution or capacity reasons, reconfiguration of the clients utilizing the servers is unnecessary. In one arrangement, the data resides in a data structure having (i) a device identifier that uniquely identifies the server host among multiple server hosts, and (ii) a filter index which is different than the device identifier.
