Level 20 system description
Level 20 system description
The Level 20 SAN 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 clients and other iSCSI clients, such as Aurora Edits, are connected to the GigE
switch. Each K2 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.
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
