Preparing nearline devices
Each K2 Media Server has one GigE connection for control, one GigE connection for
FTP, and one Fibre Channel connection to the RAID storage. The two iSCSI GigE
ports on the K2 Media Server are not used. Each server also runs the software
components that allow it to function in its specific roles.
The Nearline storage system uses Level 3 RAID chassis and expansion chassis. The
primary RAID chassis can have one controller (for a total of two K2 Media Servers
connected) or two controllers (for a total of four K2 Media Servers connected). The
primary RAID chassis is connected via a Fibre Channel connection to each server.
These Fibre Channel connections access the disks simultaneously for increased
bandwidth. Each controller in the Level 3 RAID chassis is also connected to the GigE
control network, which is required for SNMP (NetCentral) monitoring.
The Nearline storage system has one primary RAID chassis, which contains five 15K
rpm Fibre Channel drives. The Fibre Channel drives are required in the primary RAID
chassis only. These drives store the metadata files and journal files for the media file
system. Up to four Expansion chassis are connected to the primary RAID chassis. The
Expansion chassis contain either SATA drives or Fibre Channel drives, which
provide the main storage pool for the Nearline system.
Nearline systems have both RAID 1 and RAID 6 LUNs in the RAID storage. On the
primary RAID chassis there are two RAID 1 LUNs for media file system metadata
files and journal files. The Expansion chassis contain the remainder of the RAID
storage, which is RAID 6 LUNs. SATA drives on the Nearline system must be bound
as RAID 6 LUNs.
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 storage
system.
FTP/streaming traffic accesses the K2 Storage System via the FTP GigE port on K2
Media Servers. FTP/streaming traffic does not go to K2 Media Clients.
Refer to Chapter 7, Description of K2 Storage Devices for more information. Also
refer to “Design considerations for Ethernet switches” on page 388 .
Preparing nearline devices
Use the topics in this section to prepare each device so that it is ready to become part
of the nearline storage system.
• “Setting up the Control Point PC” on page 239
• “Setting up the Nearline GigE switches” on page 240
• “Setting up the K2 Media Server” on page 248
• “Setting up the L3 RAID chassis” on page 250
Setting up the Control Point PC
To set up the K2 configuration Control Point PC, you have the following options:
• Use the Grass Valley Control Point PC that comes from the factory with software
pre-installed. This includes the K2 System Configuration application, remote
AppCenter, and NetCentral software. Refer to the K2 Media Client System Guide
for rack mount instructions.
