  • Publication number: 20190332308
    Abstract: While migrating a source volume to a destination storage array, disabling the source volume causes a source storage array to send a non-standard failure status code to all host computers in a cluster that includes the source storage array and the destination storage array. While the source volume is disabled with regard to standard host I/O requests received from host computers in the cluster, in response to receipt of the non-standard failure status code, a customized plugin added to the host computers transfers persistent reservation information to the destination storage array using non-standard read and set persistent reservation information commands. The destination volume is then enabled to process host I/O requests in accordance with the transferred persistent reservation information, and an active path for accessing the source volume is modified in each one of the host computers in the cluster to indicate the destination volume in the destination storage array.

  • Publication number: 20190325370
    Abstract: Architecture that enables a Database-as-a-Service (DaaS) to auto-scale container sizes on behalf of tenants. An abstraction is provided that enables tenants to reason about monetary budget and query latency, rather than resource provisioning. An auto-scaling module automatically determines a container size for a subsequent billing interval based on telemetry that comprises latencies (e.g., waits), resource utilizations, and available budget, for example. A set of robust signals are derived from database engine telemetry and combined to significantly improve accuracy of resource demand estimation for database workloads. In a more specific implementation, resource demands can be estimated for arbitrary SQL (structured query language) workloads in a relational database management system (RDBMS).

  • Patent number: 10453992
    Abstract: An AlGaInP light-emitting diode includes from bottom up a substrate, a distributed Bragg reflector (DBR) reflecting layer, an N-type semiconductor layer, a quantum well light-emitting layer, a P-type semiconductor layer, a transient layer and a P-type current spreading layer. The DBR reflecting layer is multispectral-doping. The P-type semiconductor layer includes a first P-type semiconductor layer adjacent to the quantum well light-emitting layer and a second P-type semiconductor layer adjacent to the transient layer. A doping concentration of the second P-type semiconductor layer is lower than that of the first P-type semiconductor layer. By improving doping concentration of the multispectral DBR reflecting layer, current spreading can be improved, thus improving aging performance. A concentration difference is formed with the transient layer to balance doping of the transient layer; this avoids increasing non-radiation composition from high doping of the transient layer during long-time aging.

  • Publication number: 20190320393
    Abstract: Some wireless communications systems may support mobile broadband (MBB) communications and low latency communications. To facilitate low latency communications, a base station may assign resources allocated for an MBB transmission for a low latency transmission. As described herein, to limit interference between an MBB transmission and a low latency transmission while maximizing the chances that the MBB transmission is received, an MBB user equipment (UE) may be configured to adjust a transmit power for the MBB transmission to limit the impact on a low latency transmission without preempting the MBB transmission. However, if the MBB UE is unable to adjust the transmit power for the MBB transmission prior to the MBB transmission, the MBB UE may determine whether to drop a portion of the MBB transmission on the resources assigned for the low latency transmission (e.g., based on whether a received power of the MBB transmission exceeds a threshold).
