About networks
The following section describe networks as they apply to K2 systems. Also refer to
the K2 SAN Installation and Configuration Guide for more detailed information about
K2 SAN networking.
Control network description
The control network is for communication between devices and components. It does
not have real-time media traffic or streaming/FTP media traffic. The control network
must be on a different subnet than the streaming/FTP network and the Media (iSCSI)
network. Static IP addresses with name resolution via host files are recommended for
the control network.
Streaming/FTP network description
The streaming/FTP network is for media transfers and FTP traffic. It must be on a
different subnet than the control network and the Media (iSCSI) network. Static IP
addresses with name resolution via host files are recommended for the streaming/FTP
network. Hostnames of network adapters that are dedicated to the streaming/FTP
network must be aliased in the host file with the _heo suffix. This directs the
streaming traffic to the correct port.
Media (iSCSI) network description
The media network is exclusively for real-time iSCSI traffic on a K2 SAN. It must be
on a different subnet than the control network and the streaming/FTP network.
Furthermore, its traffic is kept physically separate from that of other networks. This
separation is provided by dedicated ports, cables, and by a dedicated VLAN on the
Ethernet switch or by separate switches. Static IP addresses are required for the media
network. Name resolution is not necessary, so media network IP addresses are not
required in host files.
