Level 30 system description
Level 30 system description
The Level 30 SAN has one Gigabit Ethernet switch, one LS K2 Media Server, and
one L30 RAID chassis. Up to eleven RAID Expansion chassis are optional for
increased storage capacity.
K2 clients and other iSCSI clients, such as Aurora Edits, are connected to the GigE
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 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.
Optional NH K2 Media Servers are available to provide additional FTP bandwidth.
These servers are available with either a one Gigabit connection or a ten Gigabit
connection. If you have multiple NH K2 Media Servers on a K2 SAN, they must all
