3.7.0 HP StorageWorks HP Scalable NAS File Serving Software administration guide - HP Scalable NAS 3.7 for Linux (AG513-96002, October 2009)

Servers. Each server must be running HP Scalable NAS.
Public LANs. A cluster can include up to four network interfaces per server. Each
network interface can be configured to support multiple virtual hosts, which provide
failover protection for Web, e-mail, file transfer, and other TCP/IP-based applications.
Administrative Network. HP Scalable NAS components communicate with each other
over a common LAN. The network used for this traffic is called the administrative
network. When you configure the cluster, you can specify the networks that you
prefer to use for the administrative network traffic. For performance reasons, HP
recommends that these networks be isolated from the networks used by external
clients to access the cluster.
Storage Area Network (SAN). The SAN includes Fibre Channel switches and RAID
subsystems. Disks in a RAID subsystem are imported into the cluster and managed
from there. After a disk is imported, you can create PSFS filesystems on it.
Software components
The HP Scalable NAS software is installed on each server in the cluster. It includes
kernel modules such as the PSFS filesystem, as well as several daemons and drivers.
HP Scalable NAS also includes a Management Console that provides a graphical
interface for configuring the cluster and monitoring its operation. The console can
be run either remotely or from any server in the cluster.
