1. A computerized method comprising:

  • obtaining, by a local storage server computer, metadata to describe hardware characteristics of a remote filesystem, the metadata stored in a local mass storage subsystem owned by the local storage server computer;

    processing, by the local storage server computer, the metadata to locate a data block in the remote filesystem, the data block stored in a remote shared-access mass storage subsystem owned by a remote storage server computer, wherein the local storage server computer has read-only access to the remote shared-access mass storage subsystem; and

    reading, by the local storage server computer, the data block from the remote shared-access mass storage subsystem using the metadata without requesting the data block from the remote storage server computer, wherein the local storage server computer reads the requested data block from the remote shared-access mass storage subsystem while the remote storage server computer accesses the remote shared-access mass storage subsystem.
