Chapter 1 Product Description
The L20 RAID chassis has redundant RAID controllers to support the Fibre Channel
connections from the K2 Media Servers. The L20 RAID chassis is also connected to
the GigE control network, which is required for SNMP (NetCentral) monitoring.
On the L20 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.
Optional NH K2 Media Servers are available to provide additional FTP bandwidth.
These servers are available with either a one Gigabit connection or a ten Gigabit
connection. If you have multiple NH K2 Media Servers on a K2 SAN, they must all
be of the same connection speed. They must be all one Gigabit servers or all ten
Gigabit servers. If the optional NH server is used, all FTP traffic goes to this server,
so neither GS K2 Media Server is cabled or configured for FTP.
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.
