When using Samba with HP Scalable NAS, you will need to use a active/passive configuration, with one node hosting the share and other nodes serving as backups. The data, or shares, to be exported are stored on PSFS filesystems. Clients access a share via a virtual Samba server. The virtual server is controlled by an HP Scalable NAS virtual host, which is configured with one node as the primary and one or more additional nodes as backups. If the primary node fails, the virtual host fails over to a backup node. The client connections can then reattach to the filesystem via the virtual host on the backup node. (Ideally, the ability to seamlessly move client connections from one node to another without reattaching would be preferable, but new node and client connections (session states) must be re-established before operations can continue.) Because of the connection-based nature of the CIFS protocol and the reconnect logic in the clients and Samba server, failover will be a disruptive event for the client only if there is data in-flight at the time of failover. The backup node for one virtual Samba server can be the primary node for another virtual server. Also, a node can broadcast multiple PSFS filesystems. The only restriction is that each PSFS filesystem can be associated with only one virtual Samba server. The core part of the solution is based on the concept of a Samba "virtual server" and the methodology is implemented with the use of a Samba macro named "%L". This technique allows a Windows client to browse the Network > Workgroup/Domain and see the configured virtual server in the list of possible servers, including the host of the virtual server. 400 Samba configuration
