摘要： When a loss of connectivity between a first node in a cluster of nodes and a data store is detected, an input/output (I/O) request associated with an application that was executing on the first node is shipped to a second node in the cluster that is in communication with the data store. The application can be gracefully shut down on the first node, and the second node can execute the application and satisfy the I/O request.

摘要： Systems and methods for fault handling are presented. In one embodiment, a fault handling method includes: performing an information collection process, wherein the information collection process includes collecting information regarding guest operating system files of a virtual machine; performing a selective replication region identification process, wherein the selective replication region identification process includes identifying regions associated with a selective amount of the guest operating system files; and performing a replication process based upon result of the replication region identification process. In one embodiment, the selective replication region identification process includes identifying regions associated with files of interest. The selective replication region identification process can include identifying regions associated with temporary files. The information regarding files can include a list of regions used by the files after loopback mounting of a virtual disk file, a list of regions which have been modified on the virtual disk file and regions associated with metadata that has changed.

摘要： Network fabric events may be utilized to proactively handle network path outages. A storage network virtualization manager may receive a network fabric event indicating a failure along a network path to a storage device and in response may initiate a proactive error handling mechanism. A storage network virtualization manager may proactively handle a network path failure before I/O requests via that network path fail. The proactive error handling mechanism may be initiated and completed prior to or without a host receiving an indication that an access request to a storage device on the network path has failed. Proactive error handling in response to network fabric events may reduce the number of I/O failures and retries and may also reduce the length of time access requests to storage devices affected by a network fabric path failure must be quiesced.
摘要翻译：网络结构事件可用于主动处理网络路径中断。存储网络虚拟化管理器可以接收指示沿着到存储设备的网络路径的故障的网络结构事件，并且响应可以发起主动错误处理机制。存储网络虚拟化管理器可以在通过该网络路径的I / O请求失败之前主动处理网络路径故障。在主机接收到对网络路径上的存储设备的访问请求失败的指示之前或之后，主动错误处理机制可以被启动和完成。响应于网络结构事件的主动错误处理可能会减少I / O故障和重试次数，并且还可以减少访问请求到由网络结构路由故障影响的存储设备的时间长度。
