Grass Valley GV STRATUS Installation v.3.1 - Manual (Page 156)

• On 64-bit devices, configure IPv4 addresses. Disable the IPv6 interface of the Control and FTP
interfaces. SiteConfig always configures IPv4 addresses for 64-bit devices.
Network considerations and constraints
• If your GV STRATUS system is on a domain, all servers and client PCs on that system that have
any interaction with Grass Valley components must be logged on to Windows with a domain
user account. Do not use a local user account.
• Do not use any 10.1.0.n or 10.2.0.n IP addresses. These are used by the K2 RAID maintenance
port and must be reserved for that purpose. If these addresses are otherwise used, maintenance
port communication errors occur.
Network load balancing
Large GV STRATUS systems can require network load balancing to support workflow requirements.
Use standard Microsoft network load balancing techniques, as referenced by the links below, to
support the requirements of your GV STRATUS system.

About host 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 later operating systems. 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
