    Abstract: Some embodiments facilitate high performance packet-processing by enabling one or more processors that perform packet-processing to determine whether to enter an idle state or similar state. As network packets usually arrive or are transmitted in batches, the processors of some embodiments determine that more packets may be coming down a multi-stage pipeline upon receiving a first packet for processing. As a result, the processors may stay awake for a duration of time in anticipation of an incoming packet. Some embodiments keep track of the last packet that entered the first stage of the pipeline and compare that with a packet that the processor just processed in a pipeline stage to determine whether there may be more packets coming that need processing. In some embodiments, a processor may also look at a queue length of a queue associated with an upstream stage to determine whether more packets may be coming.

    Abstract: In response to receiving a write request directed to a particular logical block of a storage object, a page of free space (sufficient to accommodate the payload of the write request, but smaller in size than the logical block) of a particular extent that has been selected to store contents of the logical block is allocated. The current size of the extent is smaller than the combined sizes of logical blocks that are mapped to the extent. The page is modified in accordance with a payload indicated in the write request. In response to a subsequent write request directed to the particular extent, a determination is made that the particular extent would violate a free space threshold criterion if the payload of the write request were accommodated, and an extent expansion operation is initiated.

    Abstract: A node of a distributed storage service receives a read request from a client, directed to a particular physical page storing at least a portion of a file store object. The node transmits, to the client, a particular operation sequence number (OSN), obtained from a replicated state machine, indicative of an order in which the read request was processed at the node relative to other requests directed to the file store object. The node receives a write request from the client directed to the page. The write request includes the particular OSN. The node determines whether the page has been modified after the particular OSN was obtained. If the page has not been modified since the OSN was obtained, a modification indicated in the write request is performed; otherwise, the write request is rejected.

    Abstract translation: 分布式存储服务的节点从客户端接收指向存储文件存储对象的至少一部分的特定物理页的读取请求。 节点向客户端发送从复制状态机获得的特定操作序列号（OSN），其指示相对于针对文件存储对象的其他请求，该节点处理该读取请求的顺序。 节点从客户端接收指向页面的写入请求。 写请求包括特定的OSN。 该节点确定在获得特定OSN之后页面是否已被修改。 如果自获得OSN以来页面未被修改，则执行在写入请求中指示的修改; 否则写请求被拒绝。

    Abstract: Methods and apparatus for WAN-optimized cache population at a storage gateway appliance are disclosed. A read request is received at the appliance from a client. The request is directed to a particular data block of a data chunk of a storage object of a remote storage service. A method comprises, in response to the read request, initiating a first data transfer of the data chunk from the remote storage service to an intermediate device. The method includes determining, based on one or more criteria, contents of one or more other data transfers including a second data transfer from the intermediate device to the appliance, initiating the second data transfer to transmit the requested data block to the appliance, and providing the particular data block to the client from the appliance.

    Abstract: Virtual machines may migrate between heterogeneous sets of implementation resources in a manner that allows the virtual machines to efficiently and effectively adapt to new implementation resources. Furthermore, virtual machines may change types during migration without terminating the virtual machines. Migration templates may be established to manage migration of sets of virtual machines between sets of implementation resources and/or virtual machine types. Migration templates may be established based at least in part on information provided by migration agents added to the virtual machines under consideration for migration. The migration agents may detect and augment relevant virtual machine capabilities, as well as trigger reconfiguration of virtual machine components in accordance with migration templates.

    Abstract translation: 一些实施例通过启用执行分组处理的一个或多个处理器来确定是否进入空闲状态或类似状态来促进高性能分组处理。 随着网络分组通常到达或批量传输，一些实施例的处理器确定在接收到用于处理的第一分组时，更多分组可能在多级流水线中下降。 结果，处理器可以在预期输入分组的情况下保持清醒一段时间。 一些实施例跟踪进入流水线的第一阶段的最后一个分组，并将其与处理器刚刚在流水线级中处理的分组进行比较，以确定是否可能有更多的分组需要处理。 在一些实施例中，处理器还可以查看与上游级相关联的队列的队列长度，以确定更多分组是否可能来临。
