Appendix A Level 35 K2 Storage System
L35 system description
The K2 Level 35 (L35) and Level 35 Redundant (L35R) storage system is initially
released April 2008 and is supported by K2 system software version 3.2.58. The
following description applies to the non-redundant Level 35 (L35) system.
The Level 35 storage system has one Gigabit Ethernet switch, two GS K2 Media
Servers, one optional NH1-10GE K2 Media Server, and one L30 RAID chassis. Up
to seven 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 (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 Server. 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
