Abstract: A filing system for a storage area network with inode based policy identifiers is disclosed. The filing system includes a processor and a storage device configured to store data. The processor receives an operation to perform on an object of the filing system and retrieves a policy identifier from an inode for the object. The processor then determines a policy from the policy identifier and determines whether execution of the operation is in compliance with the policy. The processor also determines an action to perform based on the determination of compliance with the policy.

Abstract: Systems and methods transparently move a file service in a clustered environment of storage filers. A first storage filer generates file service data for the file service. The first storage filer associates the file service with an identification. The first storage filer allocates the file service data to at least one memory page in the first storage filer based on the identification. The first storage filer determines an indication to transfer the file service. The first storage filer then transfers at least one memory page using the identification to a second storage filer.
