Chapter 1 Product Description
3 system. One server on a side runs as the media file system and database server while
the other server on the side 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 on a side take the role of iSCSI bridge, so that there are a total of four iSCSI
media connections on each side for increased bandwidth.
The optional NH1-10GE K2 Media Server is available to provide additional FTP
bandwidth. This server has a ten Gigabit connection to the Ethernet switch. If the
NH1-10GE is used, all FTP traffic goes to this server, so no GS K2 Media Server is
cabled or configured for FTP.
The L30 RAID chassis has redundant RAID controllers to support the Fibre Channel
connections from the K2 Media Servers. Each controller in the L30 RAID chassis has
the four optional Fibre Channel expansion ports installed, making a total of six Fibre
Channel ports on each controller. This allows the controller to act in a limited way as
a Fibre Channel switch. Two ports connect the two GS K2 Media Servers on the side
and one port can connect the optional NH1-10GE K2 Media Server. The remaining
ports are unused. The L30 RAID chassis is also connected to the GigE control
network, which is required for SNMP (NetCentral) monitoring.
On the L30 RAID chassis there are two RAID 1 RANKs (also know as LUNs) for
media file system metadata files and journal files. The remainder of the RAID storage
is RAID 5 or RAID 6 for media.
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.
