Abstract:
An apparatus includes a module to interface to a network bus. A module descriptor specifies functionality of the module. A port on the module connects to a mating connector and receives a slot location where the module is connected. A controller generates a peer-to-peer network address for the module to communicate on the network bus. The peer-to-peer network address incorporates the module descriptor and the slot location to generate a unique network address for the network bus. The peer-to-peer network address enables other peer modules on the network bus to communicate directly with the module.
Abstract:
A method for preserving volatile memory across a computer system disruption includes identifying a set of volatile memory. The set of volatile memory represents a portion of data in volatile memory to preserve during a system disruption. The method includes receiving a system event. The system event indicates that a computer system disruption will occur and that the set of volatile memory is to be written to a stable storage device. The method includes writing the set of volatile memory to the stable storage device to create a stored data set.
Abstract:
Example implementations relate to data write back. For example, a data write back system, comprising a micro-uninterruptible power supply (µUPS) module to signal a primary power supply interruption to a controller, and the controller to segregate a portion of memory, and restore data to the segregated portion of memory in response to the primary power supply interruption signal.
Abstract:
A networking infrastructure center includes a networking chassis, networking switches implemented in the networking chassis via module slots, the networking switches being swappable in the module slots to create an infrastructure topology, storage switches implemented in the networking chassis via the module slots, the storage switches being swappable to create the infrastructure topology, and a shuffler, the shuffler to detect locations of the networking switches and the storage switches to allow the networking switches and the storage switches to be placed in arbitrary locations on the networking chassis and to realize the infrastructure topology by splitting the infrastructure topology via physical signal multiplexing to physically isolate the networking switches and the storage switches.
Abstract:
Example implementations relate to data backup. For example, a data backup can include tracking a location of a data block on a first node and initiating a transfer, utilizing a backup power supply, of the data block to a non-volatile memory location on a second node in response to an interruption of a primary power supply. In addition, the data block can be restored to the tracked location of the first node responsive to a restoration of the primary power supply.
Abstract:
Example implementations relate to server node shutdown. For example, a server node shutdown can include detecting a secondary power supply integrated into a server node, receiving a primary power supply interruption signal from the secondary power supply, and initiating a sequenced shutdown of the server node in response to receiving the signal using the secondary power supply.
Abstract:
A system includes a plurality of memory of devices to store data. The system further includes a parity generation module including a checksum module to perform a checksum operation on each row of data in each of the plurality of memory devices to provide respective checksum outputs. The parity generation module further comprises an erasure parity module to perform an erasure parity operation on each column of data in each of the plurality of memory devices to provide respective erasure parity outputs. The parity generation module can evaluate the checksum output and the erasure parity output for each of the plurality of memory devices to provide parity data to indicate whether a given memory device of the plurality of memory devices contains an error.
Abstract:
A method related to removing layers in a multi-layered PCB is described. The method includes removing one of more layers of a multi-layered printed circuit board (PCB) layer via material removal techniques. The removal of the layers reduces the thickness of the multi-layered PCB in a section while the thickness in another section of the PCB is maintained. The method includes forming a recess in the section of the multi-layered PCB to provide additional spacing on the multi-layered PCB. The method further includes placing components in the recessed section of the multi-layered PCB.
Abstract:
Example implementations relate to a backup power supply in a memory cell. For example, a parallel backup power supply system can include a memory device. The memory device can include memory that is integrated in the memory device. The memory device can also include a back-up power supply cell that is integrated in the memory device and that provides back-up power supply to the memory.
Abstract:
Example implementations relate to combined backup power. For example, a system for combined backup power can include a combined backup power supply (CBPS) coupled to a node and a plurality of loads supported by the node. The CBPS can include an uninterruptible power supply (UPS) and a backup power supply coupled to the UPS to act as redundancy for the UPS.
