Abstract: A drill-bit may include a head which includes a face and a gage. The face may include a plurality of face button bits. The gage may include a plurality of gage button bits evenly spaced around the head. A plurality of major chip gage gashes may be evenly spaced around the head. A plurality of minor chip gage gashes may be evenly spaced around the head. An axis extending through centers of the plurality of face button bits may extend through one of the plurality of major chip gage gashes and one of the plurality of minor chip gage gashes. The plurality of major chip gage gashes may alternate with the plurality of minor chip gage gashes around the head. One of the plurality of gage button bits may be disposed in-between every set of the alternating major chip gage gashes and minor chip gage gashes.

Abstract: System and method for deploying software-defined data centers (SDDCs) in target computing environments uses a software-defined data center (SDDC) bootstrap service running in a virtualization software of a host computer in a target computing environment to deploy a plurality of management components of the SDDC being deployed in the target computing environment. After the management components of the SDDC have been deployed in the target computing environment, the SDDC is configured to a desired state by an SDDC configuration service running in one of the management components of the SDDC using an SDDC desired state specification.

Abstract: Examples described herein include systems and methods for parallel upgrades of multiple hosts within an on-premises, multi-rack software-defined data center (“SDDC”). Upgrade instructions can be provided to a point-of-presence (“POP”) virtual machine (“VM”) of the SDDC, which can call an application programming interface (“API”) of a pod service executing on a control plane VM in the SDDC. For example, the pod service can generate a set of instructions for performing cluster upgrades in parallel. In one example, the pod service provides the instructions to a lifecycle management service executing on a VM of the SDDC, such as the control plane VM. In some examples, the lifecycle management service can add a spare host to a cluster of hosts in order to begin upgrading one or more hosts in that cluster. This can be performed in parallel, using the spare hosts from different racks simultaneously.

Abstract: A modular rotor blade assembly includes a pair of cover plates; a base plate disposed between the pair of cover plates; a wedge disposed within a slot formed in a perimeter of the base plate; and a rotor blade attached to the wedge. One or more cover plates and/or the rotor blade with corresponding wedge are capable of being replaced without the need to replace the base plate, thereby reducing the cost or replacing the entire rotor blade assembly.
