Configuring Routing within Multi-Server Environment
DW Spectrum provides built-in automatic routing mechanism that enables users to seamlessly work with the large
sites as a single cluster. However there may be custom network configurations that may require custom routing
settings. For instance, Servers may have several IP addresses (Public and Private) and it may be necessary to allow or
restrict traffic flow for some of them.
Initially DW Spectrum tries to discover all available IP addresses of servers (including Public ones). However it is not
possible in some network environments.
To setup routing open Main Menu –> System Administration (CTRL+ALT+A) and go to Routing Management tab.
On the left all Servers are displayed. If click on Server all available interfaces are displayed in the right hand side.
 To add an address manually click "+" and add URL like Error! Hyperlink reference not valid.:
 <ip> – the desired IP address of Server (i.e. Public IP)
 <port> – network port Server is listening on (default 7001).
 To allow/deny traffic to go through the specific network interface click In Use to set/release checkbox.
For instance, Server can have Public IP address and is connected to the Internet via 100 Mbit network and local NIC
with local IP address (1Gbit). If it is not necessary to provide public access to this server it may be useful to restrict
traffic flow through Public IP.
Configuring Time Synchronization within Multi-Server Environment
DW Spectrum provides built-in time synchronization mechanism. However this mechanism synchronizes the time with
the Internet and it no Internet connection available, it may be necessary to configure time settings manually. Even in
this case DW Spectrum tries to synchronize time across servers. Manual settings are needed if it is necessary to specify
Master Time Server: the one all other Servers will synchronize to.
To do so open Main Menu –> System Administration (CTRL+ALT+A) and go to Time Synchronization tab.
Initially DW Spectrum tries to discover all available IP addresses of servers (including Public ones). However it is not
possible in some network environments.
To go to routing setup open Main Menu –> System Administration (CTRL+ALT+A) and go to Routing Management tab.
The table shows all Servers that are currently online, current time and offset from Internet time or master server time.
To specify Master Time Server tick it in the table and click OK.
