K2 Media Server failover behavior



If the following system connection or component fails to respond to network communication:

Either of the Media (iSCSI or LAN Connect) network “A” connections between the GigE switch and the K2 Media Server

The control connection between GigE switch “A” and K2 Media Server “A”

K2 Media Server “A”

The Fibre Channel connection between K2 Media Server “A” and RAID controller “A”

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 or LAN Gateway on the “B” K2 Media Server to provide access to the Fibre Channel connected RAID storage.
  3. All K2 SAN-attached systems 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”.
