An I/O manager may be configured to service I/O requests pertaining to ephemeral data of a virtual machine using a storage device that is separate from and/or independent of a primary storage resource to which the I/O request is directed. Ephemeral data may be removed from ephemeral storage in response to a removal condition and/or trigger, such as a virtual machine reboot. The I/O manager may manage transfers of ephemeral virtual machine data in response to virtual machines migrating between host computing devices. The I/O manager may be further configured to cache virtual machine data, and/or manage shared file data that is common to two or more virtual machines operating on a host computing device.

Systems and methods for storage virtualization

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.
