Distributed LAN

A StorNext client running on Windows can be configured as a distributed

LAN client or a distributed LAN server. (This is a licensed feature.)

•Distributed LAN Server: A distributed LAN server has direct access to data disks (using fibre channel) and makes the shared storage pool available to distributed LAN clients over a network.

•Distributed LAN Client: A distributed LAN client does not have direct access to data disks and instead accesses the shared storage pool by connecting to a distributed LAN server over a network. (Distributed LAN clients have full StorNext client functionality.)

Note: A StorNext client configured as a distributed LAN server requires a dedicated system. Do not run other applications or services on a system configured as a distributed LAN server.
