Chapter 2 Installing the Level 2 Storage System
Level 2 system description
The Level 2 storage system has one K2 Media Server and one L2 RAID chassis. An
Expansion chassis is optional for increased storage capacity.
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 Media Server has two GigE connections for media, one GigE connection for
control, one GigE connection for FTP, and one Fibre Channel connection to the RAID
storage. The server hosts iSCSI interface cards for the GigE media connections and a
Fibre Channel card for the RAID storage connection. The iSCSI interface cards
provide a bridge between GigE 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 L2 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.
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.
