L35 system description
This section describes the K2 Level 35 non-redundant (L35) SAN.
The Level 35 SAN has one Gigabit Ethernet switch, two GS K2 Media Servers, one
optional NH1-10GE 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 (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.
Each 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.
Server roles are distributed between the two GS K2 Media Servers. In this way the
Level 35 system is similar to the Level 3 system. One server runs as the media file
system and database server while the other server can run as an FTP server. This
boosts performance, as the system resources of each server can be optimized for
specific roles. In addition, both servers take the role of iSCSI bridge, so that there are
a total of four iSCSI media connections for increased bandwidth.
