Abstract: An apparatus for cache coherency between a device and a processor includes a buffer module that buffers data in a non-cache coherent space of an electronic device communicatively coupled to a processor. The apparatus includes an update module that updates at least one identifier with respect to the buffered data. The at least one identifier is stored in a cache coherent space of the electronic device. The apparatus includes a coherence notification module that notifies the processor of a cache incoherence. The cache incoherence indicates that the cache coherent space of the electronic device that includes the updated at least one identifier differs from a cache coherent space of the processor that includes a copy of the at least one identifier prior to the update.

Abstract: Apparatuses, systems, methods, and program products are disclosed for improved storage performance based on data placement. An identifier module generates a plurality of unique identifiers. Each of the unique identifiers is associated with a storage node of a storage cluster. A rank module ranks each of the plurality of unique identifiers in response to a received data item. The ranking of a unique identifier is based on one or more characteristics associated with the received data item. A storage module selects a unique identifier of the plurality of unique identifiers with a best ranking and stores the data item on a storage node associated with the selected unique identifier.

Abstract: A CPU package includes an encryption and decryption module disposed in a communication path between an instruction path of a processor core and a data register that is externally accessible through a debug port, and a key store accessible to the module. The module is configured to encrypt and store data in the data register for each of a plurality of processes being handled in the instruction path, wherein data owned by each process is encrypted and decrypted by the module using an encryption key assigned to the process. The key store is configured to store the encryption key assigned to each of a plurality of processes, wherein the key store is inaccessible outside the CPU package. The data is only decrypted for a requesting process having a process identifier that matches the process identifier stored in the processor data structure along with the requested data.

Abstract: An apparatus with a specific connector configuration is disclosed. A system that includes the connector configuration of the apparatus is also disclosed. The apparatus includes a first connector having a first guide pin insertable into a first guide socket of a first mating connector. The first guide pin is blocked from being inserted into a second guide socket of a second mating connector. The second guide socket has a different shape than the first guide socket. The apparatus includes a second connector having a second guide pin with a different shape than the first guide pin. The second guide pin is insertable into the first guide socket of the first mating connector and insertable into the second guide socket of the second mating connector.

Abstract: Techniques are disclosed for managing a switch fabric.

Abstract: An improved solution for limiting the transmission rate of data over a network is provided according to an aspect of the invention. In particular, the transmission rate for a port is limited by rate limiting one of a plurality of queues (e.g., class/quality of service queues) for the port, and directing all data (e.g., packets) for transmission through the port to the single rate limited queue. In this manner, the transmission rate for the port can be effectively limited to accommodate, for example, a lower transmission rate for a port on a destination node.
