Fan assemblies are disclosed. Fan assemblies include an impeller with asymmetric design.

As a result, air flow distribution from air leaving the impeller, including the locations associated with the different fan blade configurations, is relatively uniform. Beneficially, when air flow distribution uniformity increases, the fan assembly operates more efficiently, as air flow pressure losses due to flow separation are mitigated. |

Systems and methods for building and providing polymorphic rest services for heterogeneous repositories
Responsive to a request to access heterogeneous repositories, a REST server queries a resource registry to find resources that match mapping information contained in the request. The resource registry returns resource registry tables containing the matching resources. The resource registry tables implement a unified data structure of a resource registry model and are generated at runtime by the resource registry mapping REST service configuration parameters to the fields of the unified data structure. The REST service configuration parameters are added to an extension SDK for REST extension developers to enhance REST service configuration for extension applications. The REST service configuration parameters are configured at implementation time and loaded/scanned into the REST server at runtime. The REST server iteratively evaluates the resource registry tables until all the matching resources have been evaluated. The evaluation result is used to determine whether to reject, accept, or redirect the request from the client device. |

Routing of web requests to on-premise network in a multi-tenant environment
When a cloud services provider infrastructure (CSPI) receives a request from an administrator to perform an operation on an appliance, a load balancer may select a first server within the CSPI to process the request. If the first server does not have a connection with the appliance, the first server may generate a redirect response that includes server identification information identifying a particular server having a pre-established connection with the appliance. The first server may send the redirect response to the application that the administrator used to send the request. The application may then generate a second request that includes the server identification information, and send the second request to the CSPI.

Dynamic command feedback to limit impact of host-copy migration background copy load
A multi-path input-output (MPIO) driver in a host server reduces host-copy migration data transmission rate based on decrease in foreground IO response time. A baseline foreground IO response time measured before commencement of the host-copy migration is compared with a reference foreground IO response time measured after commencement of the host-copy migration. Increase in the foreground IO response time, expressed as a percentage or time value, that satisfies a predetermined limit will trigger reduction of the host-copy migration data transmission rate. The reference foreground IO response time is repeatedly measured and updated each time the host-copy migration data transmission rate is decreased. |

Distributed service chain across multiple clouds
Some embodiments of the invention provide novel methods for performing services on data messages passing through a network connecting one or more datacenters, such as software defined datacenters (SDDCs). The method of some embodiments uses service containers executing on host computers to perform different chains (e.g., ordered sequences) of services on different data message flows.

Beam steering antenna transmitter, multi-user antenna MIMO transmitter and related methods of communication
In the disclosed optically-fed transmitting phased-array architecture, transmitting signals are converted between the electrical domain and the optical domain by using electro-optic (EO) modulators and photodiodes. RF signal(s) generated from a relatively low frequency source modulate an optical carrier signal. This modulated optical signal can be remotely imparted to photodiodes via optical fibers. Desired RF signals may be recovered by photo-mixing at the photodiodes whose wired RF outputs are then transmitted to radiating elements of the antennas. The antenna array may generate a physical RF beam that transmits an RF signal that is focused on one or more selectable locations. Multiple RF beams may be simultaneously generated, each RF beam being capable of being directed to focus on a unique location or set of locations. |
