Networking tips
• Before configuring any devices for networks, determine the full scope of IP
addresses and names needed for the all the machines in your K2 system.
• It is recommended that you use the patterns offered in SiteConfig by default to
establish a consistent convention for machine names and IP addresses. You can
plan, organize, and enter this information in SiteConfig as you develop a system
description. You can do this even before you have devices installed and/or cabled.
• Work with the network administrator at your facility to have IP addresses and
names available for your use.
About hosts files
The hosts file is used by the control network and the streaming/FTP network for name
resolution, which determines the IP address of a device on the network when only the
device name (hostname) is given. The hosts file is located at
C:\Windows\system32\drivers\etc\hosts on Windows XP and Windows 2003 Server
operating system computers. The hosts file must be the same on all network devices.
It includes the names and addresses of all the devices on the network.
For FTP transfers on a K2 SAN, transfers go to/from K2 Media Servers that have the
role of FTP server. No transfers go directly to/from the shared storage K2 clients that
are on the K2 SAN. To support FTP transfers, in the hosts file the K2 Media Server
hostname must have the _he0 extension added at the end of the name and that
hostname must be associated with the K2 Media Server’s FTP/streaming network IP
address.
Here is an example of IP addresses and names associated in a hosts file:
192.168.100.11 root_server_1
192.168.101.11 root_server_1_he0
192.168.100.21 root_server_2
192.168.101.21 root_server_2_he0
192.168.100.31 root_server_3
192.168.101.31 root_server_3_he0
192.168.100.41 root_server_4
192.168.101.41 root_server_4_he0
192.168.100.51 root_raid_1
192.168.100.61 root_gige_1
In this example 192.168.100.xx is the control network and 192.168.101.xx is the
streaming/FTP network. Each K2 Media Server has its hostname associated with its
control network IP address. In addition, each K2 Media Server (that has the role of
FTP server) has its _he0 hostname associated with its streaming/FTP network
address.
