K2 Media Server failover behavior
If the following system connection or component fails to respond to network
communication:
Then the following failover behavior occurs:
1. The media file system (SNFS) and media database (SQL) on K2 Media Server “A”
fail over and K2 Media Server “B” becomes the active media file system/database
server.
2. All K2 Media 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 Media Clients use an iSCSI adapter (TOE) on the “B” K2 Media
Server to provide access to the Fibre Channel connected RAID storage.
3. All K2 Media Clients keep communicating on the same control port, finding a new
path through GigE switch “A” and across an ISL to GigE switch “B” to reach K2
Media Server “B”.
