Basic K2 SAN description



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. RAID Expansion chassis are optional for increased storage capacity.

K2 clients and other iSCSI clients, such as high resolution GV STRATUS clients, 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 also must be connected to the GigE control network. An online SAN has 2.5 inch 10K drives, with 24 drives per chassis. A production SAN has 3.5 inch 7.2K drives with 12 drives per chassis.

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.

The K2Config control point PC is connected to the GigE control network. The K2Config application runs on this PC for configuring the SAN. The SiteConfig application also runs on this PC.

FTP/streaming traffic accesses the K2 SAN via the FTP GigE port on K2 Media Servers. FTP/streaming traffic does not go to K2 clients.
