Configuring a Distributed LAN Client Server

Configuring a Distributed LAN Client Server

Traditional StorNext SAN clients access data disks using a high throughput, low-latency fibre channel connection. In addition, using the distributed LAN client and server feature, StorNext clients can access data disks over a network instead of directly accessing disks.

A StorNext client running on Linux or 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.

To configure a Linux client as a distributed LAN client, see Configuring a Distributed LAN Client on Linux. To configure a Linux client as a distributed LAN server, see Configuring a Distributed LAN Server on Linux.

To configure a Windows client as a distributed LAN server or a distributed LAN client, use the Windows Client Configuration utility. For more information, see Client Configuration on page 73 and Distributed LAN on page 81.
