Chapter 6 Installing the Level 30 Storage System
Level 30 description
The K2 Level 30 (L30) storage system was initially released with K2 system software
version 3.2 in September 2007.
The Level 30 storage system has one Gigabit Ethernet switch, one LS K2 Media
Server, and one L30 RAID chassis. Up to ten 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 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 LS K2 Media Server has four 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 iSCSI interface cards 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 L30 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.
