the RAID storage connection. The iSCSI interface card provides a bridge between iSCSI and Fibre
Channel SCSI. The server also hosts software components that allow it to function in its roles,
including media file system manager, media database server, and FTP server. Redundant K2 Media
Servers are connected by a serial cable which supports the heartbeat signal required for automatic
system recovery (failover) features.
The redundant K2 RAID chassis has redundant RAID controllers to support the Fibre Channel
connections from the K2 Media Servers. The redundant K2 RAID chassis is also connected to the
GigE control network, which is required for SNMP (NetCentral) monitoring.
On the redundant K2 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 10 Gig NH K2 Media Servers are available to provide additional FTP bandwidth. If the
optional NH server is used, all FTP traffic goes to this server, so neither K2 Media Server is cabled
or configured for FTP.
The K2Config control point PC is connected to the GigE control network. The K2Config application
runs on this PC for configuring the SAN. The SiteConfig application also runs on this PC.
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.

Basic Nearline K2 SAN description
The purpose of a Nearline SAN is to provide a large pool of storage to which files can be saved.
The Nearline system is considered an “offline” system, which means the system stores files only,

This is because the Nearline system has no media database to support “movies” or “clips”, such as
