Nearline 10 (non-redundant)
Nearline 10 Redundant
This section describes both the Nearline 10 non-redundant (NL10) and the Nearline
10 redundant (NL10R) K2 SAN. This is a 4 Gb/s Nearline K2 SAN. The 4 Gb/s
bandwidth available on this system is a feature that distinguishes it from the previous
Nearline K2 SAN, which has a 2 Gb/s bandwidth.
The purpose of the 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, 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 SAN. However, the files on a Nearline system can be readily
available to an online K2 system via FTP transfer.
