System Configuration Examples are shown below. Your site-specific entries will be different. # Gateway CLB0F118 eth0 host CLB0F118-eth0 { option subnet-mask 255.255.255.0; option routers 172.16.1.1; filename “pxelinux.0”; hardware ethernet 00:11:11:9f:d6:05; fixed-address 172.16.1.99; } # Gateway CLB0F118 eth1 host CLB0F118-eth1 { option subnet-mask 255.255.255.0; option routers 172.16.2.1; filename “pxelinux.0”; hardware ethernet 00:00:5a:72:8d:ee; fixed-address 172.16.2.99; } ContentBridge Configuration Parameters A configuration file exists for all ContentBridges. The configuration file enables you to configure parameters to: • Set up user access to files and directories • Set up file transfers, including transfer of growing files • Tune performance See the Omneon SystemManager User Guide for instructions on editing the ContentBridge configuration file. Enabling or Disabling CIFS Oplocks Disabling CIFS oplocks improves data integrity for highly concurrent applications that use file locking. The setting is disabled by default. This option only affects the operation of CIFS on a ContentBridge. Set this parameter in the configuration file on all ContentDirectors in a cluster in /tftpboot/config/config or in the /etc/gateway.conf file for a high bandwidth ContentBridge. Add the following line to the configuration file to disable CIFS oplocks: CIFS_OPLOCKS=NO 138 Installation and Configuration Guide

The acceptable options are “YES”, “NO”. Configuring a ContentServer System Configuration A configuration file exists for all ContentServers in a cluster. You can edit this file to enable certain settings and features, including the following: • Add the IP address of the log host • Set the ContentServers to reboot after a kernel panic • Set the ContentServers to reboot if they stop working • Set the amount of detail included in logs • Enable/disable jumbo frames on ContentServers and ContentBridges • Set the time zone Using SystemManager, click the View/Edit ContentServer Config button on the Omneon MediaGrid Cluster Properties page to edit the file. See the Omneon SystemManager User Guide for complete instructions. The file is located on the ContentDirector at: /tftpboot/config/config file. Editing the Slice Size Configuration File The following slice sizes are supported for individual audio and video files: 256 KB, 512 KB, 1 MB, 2 MB, 4 MB and 8 MB. Support of variable slice sizes allows more simultaneous file transfers and enables latency reduction in read operations. Changing slice sizes is done by editing the Slice Size configuration file using the SystemManager application. See the Omneon SystemManager User Guide for instructions on setting slice sizes. IMPORTANT: Do not edit the Slice Size configuration file without assistance from Omneon Technical Support. This file also includes a buffer hint value, a reserved field that should always be 0 (zero). Omneon, Now Part of Harmonic 139
