Abstract: A block-based storage system may implement page cache write logging. Write requests for a data volume maintained at a storage node may be received at a storage node. A page cache for may be updated in accordance with the request. A log record describing the page cache update may be stored in a page cache write log maintained in a persistent storage device. Once the write request is performed in the page cache and recorded in a log record in the page cache write log, the write request may be acknowledged. Upon recovery from a system failure where data in the page cache is lost, log records in the page cache write log may be replayed to restore to the page cache a state of the page cache prior to the system failure.

Abstract translation: 基于块的存储系统可以实现页面缓存写入日志记录。 可以在存储节点处接收对存储节点维护的数据卷的写入请求。 可以根据请求更新页面缓存。 描述页面高速缓存更新的日志记录可以存储在维护在永久存储设备中的页面缓存写入日志中。 一旦在页面高速缓存中执行了写入请求并将其记录在页面缓存写入日志中的日志记录中，则可以确认写入请求。 从页面缓存中的数据丢失的系统故障恢复时，可能会重播页面缓存写入日志中的日志记录，以在系统故障之前将页面缓存的状态还原到页面缓存。

Abstract: The estimated rate of work requests expected during a time period at a first block storage device, implemented at a particular server of a storage service, exceeds a provisioned rate of the first device. At a client-side component of the storage service, a different storage server is identified, at which the rate of work requests directed during the time period to a second block storage device is anticipated to be less than the provisioned rate of the second device. At least one admission control parameter of the first device is modified to enable the first storage server to accept work requests at a rate that exceeds the provisioned rate of the first device.
