Abstract: A storage module may be configured to service I/O requests according to different persistence levels. The persistence level of an I/O request may relate to the storage resource(s) used to service the I/O request, the configuration of the storage resource(s), the storage mode of the resources, and so on. In some embodiments, a persistence level may relate to a cache mode of an I/O request. I/O requests pertaining to temporary or disposable data may be serviced using an ephemeral cache mode. An ephemeral cache mode may comprise storing I/O request data in cache storage without writing the data through (or back) to primary storage. Ephemeral cache data may be transferred between hosts in response to virtual machine migration.

Abstract translation: 存储模块可以被配置为根据不同的持久性级别来服务I / O请求。 I / O请求的持久性级别可能与用于服务I / O请求的存储资源，存储资源的配置，资源的存储模式等有关。 在一些实施例中，持久性级别可以涉及I / O请求的高速缓存模式。 可以使用临时缓存模式来处理与临时或一次性数据有关的I / O请求。 短暂缓存模式可以包括在高速缓存存储器中存储I / O请求数据，而不用通过（或返回）到主存储器来写入数据。 短信缓存数据可能会在主机之间传输，以响应虚拟机迁移。

Abstract: A de-duplication is configured to cache data for access by a plurality of different storage clients, such as virtual machines. A virtual machine may comprise a virtual machine de-duplication module configured to identify data for admission into the de-duplication cache. Data admitted into the de-duplication cache may be accessible by two or more storage clients. Metadata pertaining to the contents of the de-duplication cache may be persisted and/or transferred with respective storage clients such that the storage clients may access the contents of the de-duplication cache after rebooting, being power cycled, and/or being transferred between hosts.
