Paragraph Number

262

In one embodiment, the storage request with the token directive also includes a request to reserve storage space on the storage device 150, where the requested reserved storage space is an amount of storage space that is about the same to the data segment length. In another embodiment, the request to reserve storage space is for an amount of storage space different than the data segment length. For example, if the storage device 150 is a solid-state storage device 102, the solid-state storage device 102 may be connected to a hard drive or other long-term, inexpensive storage while the solid-state storage 110 is configured as cache for the long-term storage. The request to reserve storage may cause the solid-state storage device 102 to flush a portion of the cache to the long-term storage in preparation for writing data to the solid-state storage device 102. One of skill in the art will recognize other situations were a request to reserve storage space is desired.
