Abstract: An icemaker includes a casing that receives water from a water supply and is in thermal communication with an evaporator of a sealed system that chills the casing to freeze the water. An auger is mounted within the interior volume and is rotatable to scrape the ice from the casing and urge it through an extruder to form nugget ice. A BLDC motor is mechanically coupled to the auger to selectively rotate the auger. A controller determines a target speed of the auger based at least in part on the ice production parameter, and operates the BLDC motor to rotate the auger at the target speed. The BLDC motor with the speed-closed control loop can provide the constant speed and enough torque to prevent the ice maker from freezing. The controller can adjust the PWM and the voltage will be adjusted slightly, then the torque will be adjusted accordingly.

Abstract: Some embodiments of the invention provide a method of performing end-user monitoring. At a health monitor that executes on a first host computer along with a client machine and a load balancer, to monitor health of a set of two or more servers that are candidate servers for processing packets from the client machine, the method exchanges health monitoring messages with each server in the set of servers to assess health of the servers in the set. At the health monitor, the method provides health data expressing health of the servers to the load balancer to use in determining how to distribute packets from the client machine between the servers in the set of servers.

Abstract: Some embodiments provide a method for performing data traffic monitoring. The method processes a packet through a packet processing pipeline that includes multiple stages. At a filtering stage, the method tags the packet with a set of monitoring actions for subsequent stages to perform on the packet based on a determination that the packet matches a particular filter. For each stage of a set of packet processing stages subsequent to the filtering stage, the method (i) executes any monitoring actions specified for the stage to perform on the packet and (ii) sends the packet to a next stage in the packet processing pipeline.

Abstract: Some embodiments of the invention provide a method of migrating a VM from a first host computer to a second host computer, the first host computer having a first PNIC that performs at least one of network forwarding operations and middlebox service operations for the VM. At an RDMA client executing on a set of one or more processors of the first host computer, the method directs an RDMA server executing on the first PNIC to provide networking state data associated with at least one of network forwarding operations and middlebox service operations that the first PNIC performs for the VM. The provided networking state data resides in a memory of the first PNIC that is accessible to the RDMA server. At the RDMA client, the method provides the obtained networking state data to the second host computer as part of a data migration that is performed to migrate the VM from the first host computer to the second host computer.

Abstract: Some embodiments of the invention provide a method of migrating a virtual machine (VM) from a first host computer to a second host computer, the first host computer having a first PNIC, the second host computer having a second PNIC, the first and second PNICs for performing at least one of network forwarding operations and middlebox service operations for the VM.
