Hitachi NAS (BlueArc), EMC Unity, and Isilon: System Requirements

The File System Core and File System packages are installed on a computer that acts as a proxy computer or data access node. The proxy computer sends the recall requests to the NAS file server.

You can recall stubs by using either File Share Archiver Client or the Driver for File Archiver. The recall drivers can be installed on the same client computer as the File System Agent.

    In order to support cluster failover:

    • You must use EMC Isilon SmartConnect Advanced.
    • OnePass operations uses the SmartConnect Internet Protocol (IP) address instead of the physical IP.
