K2 SAN Level descriptions
The following sections describe the pre-defined levels of the K2 SAN.
• “Level 10 system description” on page 36
• “Level 10R system description” on page 37
• “Level 20 system description” on page 39
• “Level 20R system description” on page 41

• “Nearline 10 system description” on page 51
For all levels of online (not nearline) K2 SAN’s, you can configure the SAN with the
Live Production mode enabled. This type of SAN has a shorter minimum delay
between start record and start playout when the record and play are on different SAN
K2 Summit Production Clients. To support this feature, the K2 SAN must be sized for
increased bandwidth. Contact your Grass Valley representative for specifications
relative to your needs.
For information about individual devices, refer to Chapter 10, Description of K2 SAN
Devices. Also refer to “Design considerations for Ethernet switches” on page 465 .
