Chapter 2 Installing the Level 10 Storage System
Level 10 description
The K2 Level 10 (L10) storage system was initially released with K2 system software
version 3.2 in September 2007.
The Level 10 storage system 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 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.
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.
