Key to illustrated cable paths:
Fibre Channel carrying real-time media
Gigabit Ethernet carrying traffic that is not
real-time media
A black/gray pair denotes redundant cables
This system differs from the iSCSI extended system as follows:
• K2 SAN-attached client systems have a Fibre Channel card installed and are connected directly
to the Fibre Channel Fabric. This replaces the iSCSI layer.
• Because there is no iSCSI, there is no need for multiple K2 Media Servers to act as iSCSI bridges,
reducing the total number of K2 Media Servers required.
• There is a RAID chassis dedicated for file system metadata.
• The FSM K2 Media Servers read/write data over Fibre Channel only to the metadata RAID
chassis.
• The FSM K2 Media Servers must "see" (be on the same Fibre Channel fabric with) the media
RAID, even though they do not read/write data to the media RAID.
Guidelines for this system are as follows:
• When adding a K2 SAN-attached client system in K2Config, set the Storage access option to
Fibre Channel.
• When configuring the system in K2Config, select the Server redundancy option.
