The basic (non-redundant) K2 SAN can be an online SAN or a production SAN. The SAN has one
Ethernet switch, one K2 Media Server, and one basic K2 RAID chassis. Up to eleven RAID
Expansion chassis are optional for increased storage capacity.
K2 clients and other iSCSI clients, such as Aurora Edits, are connected to the Ethernet switch. Each
K2 client has one GigE connection for media and one GigE connection for control. The GigE switch
is configured with V-LANs to keep the control/FTP traffic and the media (iSCSI) traffic separate.
The K2 Media Server has one 10 Gig connection for media (iSCSI), one GigE connection for control,
one GigE connection for FTP, and one Fibre Channel connection to the RAID storage. The server
hosts an iSCSI interface card for the 10 Gig media connection and a Fibre Channel card for the
RAID storage connection. The iSCSI interface card provides a bridge between iSCSI and Fibre
Channel SCSI. The server also hosts software components that allow it to function in various roles,
including media file system manager, media database server, and FTP server.
The basic K2 RAID chassis is connected via a single Fibre Channel connection to the K2 Media
Server. It is also connected to the GigE control network, which is required for SNMP (NetCentral)
monitoring.
Optional 10 Gig NH K2 Media Servers are available to provide additional FTP bandwidth. If the
optional NH server is used, all FTP traffic goes to this server, so the K2 Media Server is not cabled
or configured for FTP.
