LOW-LATENCY DESERIALIZER HAVING FINE GRANULARITY AND DEFECTIVE-LANE COMPENSATION
Embodiments of the invention are directed to a computer-implemented method of operating a data transmission system. The data transmission system includes a transmitter and a receiver. The computer-implemented method includes using the transmitter to send serialized data from the transmitter through a plurality of lanes to the receiver. The transmitter sends the serialized data at a first serialization ratio. The receiver is configured to receive and load the serialized data at a second deserialization ratio, wherein the first serialization ration is greater than the second deserialization ratio.
HIGH AVAILABILITY MANAGEMENT FOR A HIERARCHY OF RESOURCES IN AN SDDC
Some embodiments provide a hierarchical data service (HDS) that manages many resource clusters that are in a resource cluster hierarchy. In some embodiments, each resource cluster has its own cluster manager, and the cluster managers are in a cluster manager hierarchy that mimics the hierarchy of the resource clusters. In some embodiments, both the resource cluster hierarchy and the cluster manager hierarchy are tree structures, e.g., a directed acyclic graph (DAG) structure that has one root node with multiple other nodes in a hierarchy, with each other node having only one parent node and one or more possible child nodes.
ARCHITECTURE FOR MODULAR ENERGY SYSTEM
A modular energy system for use in a surgical environment includes a plurality of functional modules including at least an initial module, a functional module, and a terminal module. Each of the plurality of modules has a module control circuit, and a local data bus. An internal data bus is composed of a serial array of the local data busses of the modules. The local data bus may includes a communication switch, a first switch data path between the communication switch and the module control circuit, a second switch data path in communication with the communication switch, and a third switch data path in communication with the communication switch. The third switch data path of a module N is in communication with a second switch data path of a module N+1. The system further includes a termination unit in communication with the third data path of the terminal module.
Efficient high availability for a SCSI target over a fibre channel
For efficient high availability for a multi-node cluster using a processor device in a computing environment, using duplicate, standby host-bus adaptors (HBAs) for alternate nodes with respect to a node with the duplicate, standby HBAs using duplicate credentials of active HBAs of the node for shutting down the node, taking an active HBA of the node offline, and/or activating one of the alternate nodes.
Power management synchronization messaging system
A multi-die package for a microprocessor provides a power management synchronization system. The package has a plurality of dies. Each die has a plurality of cores, including a single master core. A plurality of sideband non-system-bus inter-die communication wires communicatively couple the dies to each other for a purpose of synchronizing power management. The master core of each die is configured to use one and only one of the inter-die communication wires to transmit power management synchronization messages to each of the other master cores. The master core of each die is also configured to receive power management synchronization messages from each of the other master cores via one or more inter-die communication wires. The cores use this system of inter-die communication wires to synchronize management of resources that affect both the performance and power consumption of the cores.
Data reconstruction in distributed storage systems
A method of operating a distributed storage system, the method includes identifying missing chunks of a file. The file is divided into stripes that include data chunks and non-data chunks. The method also includes identifying non-missing chunks available for reconstructing the missing chunks and reconstructing missing data chunks before reconstructing missing non-data chunks using the available non-missing chunks.
Fast protection path activation using control plane messages
A method, performed in a network that includes a group of nodes, includes identifying a path through a set of the nodes, where each node, in the set of nodes, has a data plane and a control plane; establishing a control plane tunnel, associated with the path, within the control plane of the nodes in the set of nodes; establishing a data plane tunnel, associated with the path, within the data plane of the nodes in the set of nodes, where the data plane tunnel is associated with the control plane tunnel and established through the same set of nodes; and transmitting a control message through the control plane tunnel to change a state of the data plane tunnel.
Simultaneous multi-processor apparatus applicable to achieving exascale performance for algorithms and program systems
Apparatus adapted for exascale computers are disclosed. The apparatus includes, but is not limited to at least one of: a system, data processor chip (DPC), Landing module (LM), chips including LM, anticipator chips, simultaneous multi-processor (SMP) cores, SMP channel (SMPC) cores, channels, bundles of channels, printed circuit boards (PCB) including bundles, floating point adders, accumulation managers, QUAD Link Anticipating Memory (QUADLAM), communication networks extended by coupling links of QUADLAM, log2 calculators, exp2 calculators, logALU, Non-Linear Accelerator (NLA), and stairways. Methods of algorithm and program development, verification and debugging are also disclosed. Collectively, embodiments of these elements disclose a class of supercomputers that obsolete Amdahl's Law, providing cabinets of petaflop performance and systems that may meet or exceed an exaflop of performance for Block LU Decomposition (Linpack).
Efficient handling of RAID-F component repair failures
In one set of embodiments, a storage system can execute a repair process for a first component of a file or object stored on the storage system, where the repair process is initiated in response to the first component becoming inaccessible by the storage system, and where the file or object is split across a plurality of components including the first component. The executing can include, for each chunk in an address space of the first component starting from an initial chunk pointed to by a cursor: (1) determining whether the chunk is mapped to the first component, (2) if the chunk is mapped to the first component, copying data for the chunk from a mirror copy of the first component to a second component in the plurality of components, and (3) updating the cursor to point to a next chunk in the address space.
Automatic non-disruptive connection recovery of a fixed topology fabric in a data storage system
Individual transport connections within a dual-star fabric connected multi-node storage system are disabled in response to associated failures due to faulty hardware or temporal congestion. Each configured IB transport connection is monitored for viability and, upon failure, removed from the pool of available resource. Following failure restoration the resource is tested to ensure proper functionality and then restored to the pool of resources. Mappings associated with the transport connections are maintained while the connections are disabled.
