Failure
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 SAN-attached systems 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
SAN-attached systems 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 SAN-attached systems, communication fails on the control port, so the control team
fails over and communication begins on the other control port.
4. For all K2 SAN-attached systems, control communication finds a path through GigE switch “B”
to K2 Media Server “B”.
