Chapter 9 Installing the Level 20 Storage System
Level 20 system description
The Level 20 (L20) storage system has one Gigabit Ethernet switch, one GS K2
Media Server, and one L20 RAID chassis. Up to seven RAID Expansion chassis are
optional for increased storage capacity.
K2 Media Clients and other iSCSI clients, such as Aurora Edits, are connected to the
GigE switch. Each K2 Media Client has one GigE connection for media (iSCSI) 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 GS K2 Media Server has two GigE connections 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 a dual-port iSCSI interface card for
the GigE media connections and a Fibre Channel card for the RAID storage
connection. The iSCSI interface card provides 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 L20 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.
