System Installation with ContentServer 1000 and 2000 Series Figure 23. Basic Omneon MediaGrid System—Network Topology NOTE: In Figure 23, note the following: • The blue cables and the gray cables represent different connections on the same Public VLAN. To allow failover, the blue cables must be connected to a separate switch from the gray cables. • Private VLAN 1 is a dedicated VLAN defined on the 1GbE switch shown on the left. Private VLAN 2 is a dedicated VLAN defined on the 1GbE switch shown on the right. The ContentDirectors must communicate on both private VLANs. 58 Installation and Configuration Guide
The following software installation procedure is also required: • Installing the File System Driver System Installation with ContentServer 1000 and 2000 Series A separate ContentManager application is also available from Omneon. ContentManager is used for setting, reviewing and changing attributes on associated files, directories, and user permissions of Omneon MediaGrid. Refer to the Omneon ContentManager User’s Guide for more information. About Setting up Groups of ContentServers 1000 or 2000 Series Users may segment an Omneon MediaGrid Volume into one or more Groups of ContentServers for the purpose of influencing where replicated slices are stored. When more than one group is configured, Omneon MediaGrid’s replication scheme ensures that different slices are replicated in different groups. The most common use of this feature is to ensure that if one group fails (for example, due to a power strip failure) then at least one copy of this content is still available in other groups of ContentServers that are perhaps powered by different sources. Keep in mind the meaning of these concepts: • A Cluster is a collection of one or more Volumes and their associated ContentDirectors and ContentServers within an Omneon MediaGrid. • A Volume is a collection of one or more Groups and their associated ContentServers in an Omneon MediaGrid. • A Group is a collection of one or more ContentServers in an Omneon MediaGrid. Note the following points: • A group can belong to at most one volume. • The number of groups should be equal to or slightly higher than the expected replication factor. Pick the desired replication factor, and then set up a grouping arrangement that best supports that replication factor. • Avoid creating too many groups. Groups are only useful for isolating power and network failures. The suggested maximum is less than nine groups. • If there are more than two racks of ContentServers, it is suggested that you limit a group to an entire rack, instead of multiple groups within a rack. • Avoid having too few ContentServers in a group. There should be at least 12 ContentServers in every group to avoid “hotspots.” • All groups should have an equal number of ContentServers within a cluster. • Refer to About Mixed ContentServer 1042 (1U) and 2122/2124 (2U) Configurations for information about grouping these ContentServers. See the Omneon SystemManager User Guide for more information and for instructions on setting up groups. Omneon, Now Part of Harmonic 59
