Networking requirements
Networking strategies for a Nearline Storage System are as follows:
• Two networks:
NOTE: The Nearline Storage System does not use the K2 media (iSCSI) network.
• Streaming/FTP network — For media transfers and FTP traffic. This is the
primary network for media moving to and from the Nearline storage system.
• Control network — For all other non-streaming, non-iSCSI traffic.
• Networks must be on separate subnets.
• While control and FTP traffic is each on its own subnet, it is not required that each
type of traffic has its own VLAN on GigE switches. For example, you make both
FTP and control connections to the “control” ports (DEFAULT_VLAN) on the HP
GigE switch.
• Machine names (host names) assigned to each K2 device.
• IP addresses for FTP/streaming ports must have name resolution such that
hostnames are appended with the “_he0” suffix. You can use host tables (as in
“Setting up host tables” on page 367 ) or another mechanism to provide the name
resolution. This directs the streaming traffic to the correct port. Refer to the K2
Media Client System Guide for a complete explanation.
• NH K2 Media Servers must be on the streaming network, as they provide the FTP
interface for nearline storage streaming traffic.
Also refer to “About networks and FTP” on page 426 and “Design considerations for
Ethernet switches” on page 509 .
Use the following procedures as necessary to implement your networking strategies.
NOTE: It is recommended that you configure Streaming network IP addresses
using the K2 System Configuration application, rather than doing so on the local
machine using standard Windows procedures.
Networking tips
• Before beginning network configuration, determine the IP addresses and names
needed for the machines in your K2 system. Work with the network administrator
at your facility to have those IP addresses and names available for your use.
