Storage area network methods and apparatus for identifying fiber channel devices in kernel mode

摘要

The invention provides an improved storage area network (SAN) of the type that has a host or other digital data processor whose ports are coupled to peripheral devices that include fiber channel or other SAN-class storage devices. Processes executing on the host (or other digital data processor) generate requests for access to those peripheral devices. A persistent store identifies ports coupled to SAN-class storage devices. This store can be loaded, for example, by a process that executes on the host in user mode. A filter executes on the host in kernel mode to block access to selected ones of those SAN-class storage devices.
