Chapter 1 Product Description
Overview Description
The K2 Storage System is Grass Valley’s shared storage solution that gives multiple
clients access to a common pool of media. Clients access the shared media storage via
a Gigabit Ethernet network and a Fibre Channel connection. Data is communicated
using the Small Computer System Interface (SCSI) data transfer interface and the
Internet SCSI (iSCSI) protocol.
Refer to the sections later in this manual for the system description of each of the
different levels of storage available, as follows:
• “Level 2 system description” on page 26
• “Level 2R system description” on page 70
• “Level 3 system description” on page 126
• “Level 3R system description” on page 174
Refer to the K2 Media Client System Guide for diagrams and explanations of the
media file system and the media database.
The Grass Valley K2 Media Client can also support a direct Fibre Channel connection
to the storage. Contact your Grass Valley representative for more information.
