Content is chopped into slices and stored across multiple ContentServers.

Slices are replicated on more than one ContentServer for protection. No RAID.

Access bandwidth scales with number of ContentServers and replication factor

Simultaneous file operations are distributed across all ContentServers whichhave relevant content

Each ContentServer operates independently and directly with clients to satisfyaccess requirements

Metadata


Lost drives or ContentServers do not necessitate a volume rebuild, as in RAID

The ContentDirector initiates creation of additional copies of missing filesegments in parallel across all ContentServers

When a ContentServer or drive is replaced, it appears as new storage to beutilized in the system

Cluster, Volume, Group, ReplicationFactor



22/27

Cluster, Volume, Group

A MediaGrid Cluster refers toa collection of one Volume

and their associatedContentDirectors andContentServers within anOmneon MediaGrid.

Volumes can be consideredthe same as filesystems

One or more ContentServerscreate a group.

One or more groups create avolume.


23/27


Grouping ContentServers is a simple yet powerful way to

orchestrate the placement of replicated images of slices

across ContentServers and to align slices with thephysical characteristics of the Cluster.

possible and never within the same ContentServer.

Groups should only consist of ContentServers in the

same physical enclosure (rack). This implementationprovides the ability to access a replicated slice even in

the case of an entire lost/failed enclosure (rack).


24/27


Avoid making more than one Group per rack (applicable

only to 1RU CSS) in a Cluster unless needed. There are

some cases where you may be tempted to use multipleGroups:

Power supply isolation of ContentServers: If ContentServers are on

separa e power s r ps, en crea e a roup or eac power s r p. o

not create too many Groups.

Network isolation of ContentServers. If ContentServers are on

separate network switches, then create a Group for each network

switch. Do not create too many Groups.


25/27


The suggested maximum number of Groups is less than

nine. Once you have more than two racks of

ContentServers, Omneon suggests limiting a Group to awhole rack, instead of multiple Groups within a rack.

higher than the expected replication factor. More Groupsdo not help.


26/27

About Replication Factor

Omneon recommends the following:

Set the replication factor to less than or equal to the number of

Groups within a Cluster.

Do not set the replication factor to 1 or 0. Factors of 1 or 0 mean no

replication will take place.

Note that the default replication factor is 3 which means 3copies of the file will be created.
