    Abstract: A cache cluster is configuration-aware such that client initialization, access to replicated cached data and changes to the underlying structure of the cache cluster can be dynamically updated. For example, a management system monitoring a cache cluster notices a large number of requests for a key that causes a significant load on a first memory caching node. To reduce the load on the first memory caching node, the management system may cause cached data related to the key to be replicated to a second memory caching node. A configuration stored in one or more of the memory caching nodes may be updated by the management system to allow both memory caching nodes to serve the requests for the key to clients.

    Abstract translation: 高速缓存集群具有配置感知能力，可以动态更新客户机初始化，对复制的缓存数据的访问以及对缓存集群的底层结构的更改。 例如，监视高速缓存集群的管理系统通知大量的对第一内存缓存节点造成重大负载的密钥请求。 为了减少第一存储器高速缓存节点上的负载，管理系统可以使与密钥相关的高速缓存的数据被复制到第二存储器高速缓存节点。 存储在一个或多个存储器高速缓存节点中的配置可以由管理系统更新，以允许存储器高速缓存节点向客户端发送对密钥的请求。

    Abstract: A network device, such as a Network Interface Card (NIC), can have a receive queue (RxQ) that changes size based on whether the network device is in a normal operating mode or in a maintenance mode. In a normal operating mode, it is desirable that the receive queue has a smaller number of free buffers, to increase cache locality in a processor subsystem. However, there can be known periods when the receive queue can be overloaded. During a maintenance period, it is desirable that the receive queue absorbs a large burst of network packets while the processor subsystem is not processing the packets. A solution is to maintain a receive queue at a smaller percentage of its maximum during the normal operation mode, but then before or upon entering the maintenance mode, expand the receive queue to a larger size.

    Abstract: A management system may enable and monitor a cache or other cluster to make the cluster configuration-aware such that initialization and changes to the underlying structure of the cluster can be dynamically updated. For example, a distributed memory caching system may provide initial configuration to a client from a memory caching node referenced by an alias provided by a configuration endpoint. Updates of configuration may be retrieved from memory caching nodes, each storing current configuration of the cache cluster. A management system monitors changes to the cache cluster, such as provisioning of new caching nodes, and updates the configuration stored in the caching nodes for retrieval by a client.

    Abstract translation: 管理系统可以启用和监视高速缓存或其他集群以使得集群配置感知到能够动态更新集群的基础结构的初始化和更改。 例如，分布式存储器高速缓存系统可以从由配置端点提供的别名引用的存储器缓存节点向客户端提供初始配置。 可以从存储器高速缓存节点检索配置的更新，每个缓存节点存储高速缓存集群的当前配置。 管理系统监视缓存集群的更改，例如提供新的缓存节点，并更新存储在缓存节点中的配置以供客户端检索。
