K2 Media Server failover with Control team failover behavior
If the following system connection or component fails to respond to network communication:
• The “A” GigE switch
Then the following failover behavior occurs:
1. The media file system (SNFS) and media database on K2 Media Server “A” fail over and K2
Media Server “B” becomes the active media file system/metadata server.
2. All K2 clients drop communication on the “A” media port and begin using the “B” media port,
finding a path through GigE switch “B” to K2 Media Server “B”. All K2 clients use an iSCSI
adapter (TOE) on the “B” K2 Media Server to provide access to the Fibre Channel connected
RAID storage.
3. For all K2 clients, communication fails on the control port, so the control team fails over and
communication begins on the other control port.
4. For all K2 clients, control communication finds a path through GigE switch “B” to K2 Media
Server “B”.
