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.

Cache coherency between a device and a processor

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.

Storage performance based on data placement

Methods and systems of identifying and remediating at-risk resources in a computing environment are provided. A method includes periodically determining respective infrastructure topologies of a computing environment that changes over time, wherein the determining is performed by a computer system communicating with the computing environment. The method also includes: identifying, by the computer system, an intrusion event in the computing environment; determining, by the computer system, at-risk resources in the computing environment based on the determined intrusion event and a corresponding one of the infrastructure topologies; and performing, by the computer system, remediation action for the at-risk resources.

Identifying and remediating at-risk resources in a computing environment

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.

Secure processor for multi-tenant cloud workloads

A computer-implemented method includes receiving, by a computing device within a networking environment, a workload for execution within the networking environment; initiating, by the computing device, transfers of the workload to a plurality of network elements within the cloud networking environment; providing, by the computing device, tracking information of the workload as the workload traverses through the plurality of network elements; and storing or outputting, by the computing device, the tracking information regarding of the workload.

Tracking cloud workloads to isolate security breach exposure

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.

Mid-plane connector configuration

Techniques are disclosed for managing a switch fabric. In one embodiment, a server system is provided that includes a midplane, one or more server cards, switch modules and a management controller. The midplane may include a fabric interconnect for a switch fabric. The one or more server cards and the switch modules may be operatively connected to the midplane. The switch modules may be configured to switch network traffic for the one or more server cards. The management controller may be configured to manage the switch modules via the fabric interconnect.

Switch fabric management

Techniques are disclosed for reducing impact of a repair action in a switch fabric. In one embodiment, a server system is provided that includes a first interposer card that operatively connects one or more server cards to a midplane. The first interposer card may include a switch module that switches network traffic for the one or more server cards. The first interposer card may be hot-swappable from the midplane, and the one or more server cards may be hot-swappable from the first interposer card.

Reducing impact of a repair action in a switch fabric

Techniques are disclosed for reducing impact of a switch failure in a switch fabric. In one embodiment, a server system is provided that includes a midplane, one or more server cards and one or more switch cards. The midplane may include a fabric interconnect for a switch fabric. The one or more server cards may be coupled with the midplane, where each server card is hot-swappable from the midplane. The one or more switch cards may also be coupled with the midplane, where each switch card is also hot-swappable from the midplane. Each switch card includes one or more switch modules, and each switch module is configured to switch network traffic for at least one server card.

Reducing impact of a switch failure in a switch fabric via switch cards

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.

Limiting transmission rate of data

Techniques are disclosed for reducing impact of a switch failure and/or a repair action in a switch fabric. In one embodiment, a server system is provided that includes a first interposer card that operatively connects one or more server cards to a midplane. The first interposer card may include a switch module that switches network traffic for the one or more server cards. The first interposer card may be hot-swappable from the midplane, and the one or more server cards may be hot-swappable from the first interposer card. The server system may further include an interconnect between the first interposer card and a second interposer card.

Reducing impact of repair actions following a switch failure in a switch fabric

An apparatus, system, and method are disclosed for distributing configuration parameters. The present invention includes one or more storage devices configured to store data, a first DHCP server configured to process DHCP messages and redirect communications regarding configuration parameters for the storage devices to a second DHCP server, and a configuration datastore configured to store configuration parameters for the storage devices. The second DHCP server may be configured to process DHCP messages and retrieve configuration parameters for the storage devices from the configuration datastore. In certain embodiments, each storage initiator communicates with the DHCP servers, receives the configuration parameters such as iSCSI parameters, and provides the configuration parameters to one or more storage devices.
