Memory bandwidth throttling for virtual machines
Systems and methods are disclosed for throttling memory bandwidth accessed by virtual machines (VMs). A technique for dynamically throttling the virtual computer processing units (vCPUs) assigned to a VM (tenant) controls the memory access rate of the VM. When the memory is shared by multiple VMs in a cloud-computing environment, one VM increasing its memory access rate may cause another VM to suffer memory access starvation. This behavior violates the principle of VM isolation in cloud computing. In contrast to conventional systems, a software solution for dynamically throttling the vCPUs may be implemented within a hypervisor and is therefore portable across CPU families and doesn't require specialized server-class CPU capabilities or limit the system configuration. |

Microservice termination while maintaining high availability
The techniques disclosed herein enable systems to reduce the time required to terminate a set of microservices for an application while ensuring high availability and preventing request failures. This is accomplished through a termination manager which retrieves request queues for the microservices to analyze outstanding requests that require processing prior to termination. Based on the outstanding requests, the termination manager constructs call graphs for each request. The call graphs capture the operational flow of the associated request by defining a sequence of microservices whose functionality is invoked by the request. From an initial analysis, the termination manager can determine that some of the microservices do not appear in the call graphs, indicating that the microservices are not needed to process the outstanding requests. Accordingly, the unneeded microservices are terminated. As requests are processed by the remaining microservices, the termination manager gradually terminates the remaining microservices based on the call graphs. |

In turn, the encoded data portion may be divided into a plurality of sub-portions, each of which may be written to different media surfaces in a storage drive. The sub-portions may be read from the different media surfaces and combined to generate a recreated encoded data portion that is decoded using the coding scheme.

Non-volatile storage system with program execution decoupled from dataload
Technology is disclosed for a non-volatile memory system that decouples dataload from program execution. A memory controller transfers data for a program operation and issues a first type of program execution command. When in a coupled mode, the die programs the data in response to the first type of program execution command. When in a decoupled mode, rather than program the data into non-volatile memory cells the die enters a wait state. Optionally, the memory controller can instruct another die to execute a memory operation while the first die is in the wait state. In response to receiving a second type of program execution command from the memory controller when in the wait state, the first die will program the data into non-volatile memory cells. The memory controller may issue the second type of program execution command in response to determining that sufficient power resources (or thermal budget) exist. |

Selective device power state recovery method
The present disclosure generally relates to reducing exit latency when transitioning from non-operational power states. Before entering a non-operational power state, specific data in databases and/or tables can be identified as being recently utilized by the host device. In addition to saving the databases and/or tables, a recovery code is also stored to identify that specific data. Upon transitioning back to an operational power state, the recovery code is detected and the specific data can be recovered rather than recovering the entire database and/or table. Data not identified in the recovery code need not be recovered from always-on memory. In so doing, when transitioning back to an operational power state, the latency will be reduced compared to a situation where all data is stored in always-on memory. |
