Page 23: Key Features
PowerVault NX3500 Views Client View To the client, the PowerVault NX3500 presents itself as a single file-server with a single file system, IP address, and name. The PowerVault NX3500's global file system has the ability to serve all users concurrently without performance constraints.
Page 24: System Components
The configuration consists of two controllers in a cluster to ensure that there will be no single point of failure. The PowerVault NX3500 software is installed on each of the controllers. The software is a complete package, consisting of an operating system, volume management, distributed file system, and clustering technology.
Page 25: Powervault Md Storage
PowerVault MD Storage The controllers connect to the PowerVault MD iSCSI storage array, which is a RAID subsystem. RAID storage subsystems are designed to eliminate single points of failure. Each active component in the storage subsystem is redundant and hot- swappable.
Page 26: Internal Network A
The connection between PowerVault NX3500 and the LAN/client network is based on a virtual IP (VIP) address that serves every controller in the cluster. The VIP address allows clients to access the PowerVault NX3500 as a single entity, thereby providing access to the file system. It enables the PowerVault NX3500 to perform load balancing between controllers, and ensures that the service continues even if a controller fails.
Page 27 The LAN/client network is comprised of two Gigabit Ethernet NICs on each controller, which connect to LAN/client network switches. The PowerVault NX3500 solution and the MD storage arrays are administered from the LAN/client network. Introduction...
