Chapter 1 Product Description
Level 10 system description
The Level 10 SAN has one Gigabit Ethernet switch, one GS K2 Media Server, and
one L10 RAID chassis. Up to four 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 one GigE connection 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 an iSCSI interface card for the GigE
media connection 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 GS
K2 Media Server has redundant power supplies.
The L10 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 SAN.
FTP/streaming traffic accesses the K2 SAN via the FTP GigE port on K2 Media
Servers. FTP/streaming traffic does not go to K2 clients.
