Failover behaviors
Failover behaviors
If a fault occurs and one of the failover mechanisms is triggered, a redundant K2
Storage System behaves as explained in following sections.
The diagrams that follow illustrate the media (iSCSI) and control paths as they
interact with the redundant K2 Media Servers in their role of media file system/
database server and iSCSI bridge. Interactions of FTP traffic and/or paths involving
K2 Media Servers with other roles are not illustrated.
Pre-failover behavior
The system operates initially with both media and control traffic on GigE switch “A”
and K2 Media Server “A”. Media (iSCSI) traffic is using media network “A”. The
iSCSI adapters (TOEs) on the “A” K2 Media Server provide access to the Fibre
Channel connected RAID storage. K2 Media Server “A” is the media file system/
database server.
