Chapter 2 Installing the Level 1 Storage System
Level 1 system description
The Level one storage system has one Level 1 device, which provides the combined
functionality of a K2 Media Server and a RAID storage device. The L1 device chassis
has two GigE connections for media (iSCSI), one GigE connection for control, and
one GigE connection for FTP. The L1 device chassis hosts an iSCSI interface card for
the GigE media connections. The iSCSI interface card provides a bridge between
iSCSI and the internal SCSI connection to the RAID drives. The L1 device chassis
also hosts software components that allow it to function in various roles, including
media file system manager, media database server, and FTP server.
K2 Media Clients and other iSCSI clients, such as Aurora Edits, are connected to the
GigE switch. Each 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 configuration control point PC is connected to the GigE control network. The
K2 System Configuration application runs on this PC for configuring the storage
system.
FTP/streaming traffic accesses the K2 Storage System via the FTP GigE port on K2
Media Servers. FTP/streaming traffic does not go to K2 Media Clients.
