Chapter 6 Installing the Nearline Storage System
Networking for nearline
Use the topics in this section to configure the Gigabit Ethernet (GigE) network for the
nearline storage system.

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.
• K2 Media Servers have a dedicated FTP port. If the server takes the role of FTP
server, make a dedicated FTP connection to the FTP port.
• 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 257 ) 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.
• Nearline K2 Media Servers must be on the streaming network, as they provide the
FTP interface for shared storage streaming traffic.
Also refer to “About networks and FTP” on page 318 and “Design considerations for
Ethernet switches” on page 388 .
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.
