Abstract: In a clustered environment, computer nodes work together to provide high availability and reliability for applications and services. To keep the compute nodes synchronized, a cluster employs a witness service, which typically operates on a separate system. In addition to issues related to potential loss of the witness service, there are also issues of additional costs and overhead. In one or more embodiments, two or more compute nodes of a cluster include a data processing unit (DPU) system operating a witness service. For a compute node with a local DPU system that operates a local witness service, the local witness service handles data related to the local workload(s) and may synchronize with one or more remote witness services on remote DPUs in the cluster in the event of failure or other issues.

Abstract: A tilting chassis vehicle has a differential gear driving opposed half shafts (16,18). Each half shaft is connected to a respective wheel hub. Pivoting tie rods (24,26) are provided between the chassis (12) and these wheel hubs, and a control arm (48) is provided between the chassis and the differential carrier to constrain movement thereof. The arrangement gives a novel tilting vehicle with shaft drive and low centre of gravity.

Abstract: An automated system adaptation technique for computer systems, networks and subsystems generally and, more particularly, for data storage systems. The invention programmatically designs, configures and manages a system, such as a data storage system. This is accomplished by performing a sequence of steps in an iterative loop, including analyzing the operation of the system under a workload, generating a new design based on the analysis and migrating the existing system to the new design. By systematically exploring a large design space and developing designs based on analyses of the workload, the invention generates designs that are improved in comparison to conventional design techniques. By programmatically repeating these tasks, the invention causes the system to converge to one that supports the workload without being over-provisioned.
