Abstract
In one embodiment of the present invention, a method and system are provided to control access to the non-volatile log (NVlog) of a storage server. By controlling access to the NVLog of a storage server the relative disk write bandwidth available to different client write requests can be controlled. The incoming write request can be categorized, and, during times of heavy load, only be permitted to use NVLog space as permitted based on the categorization of each write request. In one embodiment, the present invention includes receiving a write request from a client at a storage server, and determining whether the received write request can be presently logged in a NVlog based on a category of the write request.
