APPENDIX C:
OPTIMO
SERVER CLUSTERS
A cluster of
Optimo
Servers is comprised of a single management server, or node, and one or more
worker servers (nodes). A cluster functions as a single transcoding engine, distributing the total workload
to available nodes. Nodes in a cluster share a single, common database, common system time, and file
system share. All cluster nodes execute transcoding jobs, and each provides an identical user interface to
the cluster. Both management and worker nodes require NAS/SAN connectivity.
Optimo
Server Cluster Configuration
THE MANAGEMENT NODE
The management node of a cluster is the
Optimo
Server installation that:
§
Maintains and runs the server database.
§
Provides the server’s REST web service interface.
§
Maintains and exports a file system share that contains the server’s incoming, outgoing and
completed file locations, as well as the pre-configured watch folder directories.
§
NTP time server to synchronize system time with all worker nodes.
If a management node is configured with dual network interfaces, the REST web service and database
traffic use the first (control) NIC.
When preparing an
Optimo
Server cluster, the management node should
always
be configured before
any worker nodes.
