Chapter 13 Installing the Nearline 10 Storage System
Nearline 10 system description
Nearline 10 (non-redundant)
Nearline 10 Redundant
This section describes both the Nearline 10 non-redundant (NL10) and the Nearline
10 redundant (NL10R) K2 Storage System. This is a 4 Gb/s Nearline K2 Storage
System. The 4 Gb/s bandwidth available on this system is a feature that distinguishes
it from the previous Nearline K2 Storage System, which has a 2 Gb/s bandwidth.
The purpose of the Nearline storage system 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, such GXF files or MXF files, with no ability
to record or play those files directly on the system. This is because the Nearline
system has no media database to support “movies” or “clips”, such as there is on an
“online” K2 Level 10, 20, or 30 storage system. However, the files on a Nearline
system can be readily available to an online K2 system via FTP transfer.
