摘要： A storage device uses non-volatile memory devices for caching. The storage device operates in a mode referred to herein as write-back mode. In write-back mode, a storage device responds to a request to write data by persistently writing the data to a cache in a non-volatile memory device and acknowledges to the requestor that the data is written persistently in the storage device. The acknowledgement is sent without necessarily having written the data that was requested to be written to primary storage. Instead, the data is written to primary storage later.

摘要： Dirty data in a storage device is made current through rapid re-silvering, which uses a mirrored and up-to-date version of the dirty data from another storage device to recover the data. Because under rapid re-silvering cache metadata in volatile memory survives the failure of the cache, the cache metadata is used to determine which subset of data from the other storage device needs to be copied to the storage device being re-silvered. During re-silvering, cache metadata is used to determine which I/O requests from clients are requests for data that is not stale.
摘要翻译：存储设备中的脏数据通过快速重新刷新而成为最新版本，其使用来自另一存储设备的镜像和最新版本的脏数据来恢复数据。因为在快速重新刷新缓存中，缓存中的元数据可以在高速缓存的故障中幸存下来，所以使用高速缓存元数据来确定来自其他存储设备的哪个数据子集需要被复制到被重新映射的存储设备。在重新镀银期间，使用缓存元数据来确定来自客户端的哪些I / O请求是不过时的数据请求。

摘要： Methods, computer-readable media, and computer systems are provided for initiating storage of data on multiple storage devices and confirming storage of the data after the data has been stored on one but not necessarily all of the devices. A storage server receives, from a client, a request to store data. In response to the request, the storage server initiates, in parallel, storage of the data on multiple storage systems. The storage server detects that the data has been stored on any one of the storage systems, such as an auxiliary system, and, in response, indicates, to the client, that the data has been stored. The storage server may flush or discard data on the auxiliary storage system upon detecting that the data has been successfully stored on a target storage system, where the data persists.

摘要： Systems, methods, and other embodiments associated with detecting a node death in a clustered distributed system are described. In one embodiment, a method includes transmitting a ping message to a peer node in the network. If a reply to the ping message is not received from the peer node, a query is sent to table of port identifiers that lists ports in the cluster. In one embodiment, the query includes a port identifier associated with the peer node. The peer node is declared as inactive/dead when the query fails to locate a match in the table for the port identifier. When the query locates a match in the table for the port identifier, another ping message is periodically transmitted to the peer node.

摘要： A digital image capturing module assembly and method of fabricating the same is proposed, which is used for the assembly of a digital image capturing module from a photosensitive printed circuit board and a lens holder. The proposed module assembly is characterized by the use of aligning posts on the lens holder to help align and secure the photosensitive printed circuit board in position on the lens holder as well as by the use of a washer to help provide a sealed light-impenetrable effect at the junction between the photosensitive printed circuit board and the lens holder so that no sidelight can pass therethrough to the inside of the lens holder. This feature allows the assembly process to be more simplified and less time-consuming to implement than prior art, which can help increase the yield of the assembly of digital image capturing module.
