    GV STRATUS Insights & Highlights
    K2 Infrastructure
    GV STRATUS/K2 Media Enterprise Network

    K2 Infrastructure

    K2 incorporates and optimizes the latest in high-performance computing and storage technologies with easy integration and flexible implementations.

    The GV STRATUS framework includes Grass Valley K2 system infrastructure and third-party infrastructure components. Interacting with the K2 media servers and storage, GV STRATUS provides a unified, expandable and collaborative foundation for new applications and workflows.  
    The K2 series of servers and storage provides an IT-optimized infrastructure for a broad range of broadcast media environments.  K2 systems are comprised of various components that can be configured in a variety of ways. The K2 Summit and K2 Solo clients are used for encoding and decoding of video. These devices contain media, networking and control interfaces. The K2 Summit clients can contain integrated internal storage and so operate as standalone units similar to the smaller (and portable) K2 Solo. These compact purpose-built media clients offer a high density of capabilities. Some of these features include low-resolution proxy creation for applications and monitoring, flexible channel configurations for HD/SD with conversion, 3D, video/key, super slow-motion, multicam record, effects and monitoring options using the integrated VGA multiviewer and secondary SDI outputs.
    Without internal storage, K2 Summit clients connect to a K2 server. The shared storage modules also connect to the K2 server to form a media SAN. The K2 server manages the file system, quality of service and file transfers. Systems are scalable for channel count, bandwidth, storage capacity and level of redundancy.
    The K2 storage architecture provides flexibility for integration with a diverse range of applications including third-party systems. The file system enables easy integration with popular nonlinear editors, including Grass Valley EDIUS, Apple Final Cut Pro 7, Adobe Premiere and Avid Media Composer and NewsCutter. Interoperability is also possible with other systems such as asset management and archive via industry-standard file formats.  Sophisticated, open APIs have been created and are supported to provide true platform extensibility. Other enhancements for file base operation include shared services for file formats, proxy, EDL, playlists and metadata.
    They key to file-based infrastructure is bandwidth. The K2 platform features a quality of service algorithm with dynamic allocation of bandwidth where it’s needed, guaranteeing that on-air channels never drop a frame of video while simultaneously supplying high-bandwidth FTP file transfer capabilities.

    GV STRATUS/K2 Media Enterprise Network

    Combining K2 media servers and storage with GV STRATUS provides a unified, expandable and collaborative foundation for nonlinear production.
    The K2 series of servers and storage provides broadcast-optimized IT infrastructure for a broad range of broadcast media environments. Teamed with GV STRATUS, the various components of the K2 systems can be configured in a variety of ways into customer-specific solutions.

    Small GV STRATUS System
    A small GV STRATUS system is characterized by proxy stored on a Core Services server that includes the role of Proxy Server. The GV STRATUS Core Services server has internal storage to store proxy media. The server provides a CIFS share that GV STRATUS client PCs mount for access to the proxy.
    This type of small GV STRATUS system is designed for a basic workflow and can consist of a standalone K2 system, a GV STRATUS Core Services server and one or more GV STRATUS client PCs. Client PCs that are connected to a corporate LAN or to the control network use a proxy media workflow. At least one PC must host the GV STRATUS Control Panel application. A designated PC on the control network hosts the SiteConfig application.



    Medium GV STRATUS System
    A medium GV STRATUS system is characterized by proxy stored on the online or production K2 SAN.
    Attached to the K2 SAN is a Core Services server which has the role of Proxy Server. This Proxy Server provides access to the low-resolution proxy media stored on the K2 SAN. This server provides a CIFS share that GV STRATUS client PCs mount for access to the proxy.
    This type of medium GV STRATUS system is designed for a typical workflow and consists of a K2 online or production SAN, multiple GV STRATUS Core Services servers and multiple GV STRATUS client PCs. Client PCs that are connected to a corporate LAN or to the control network use a proxy media workflow. Client PCs that are connected to the media (iSCSI) network use a high-resolution media workflow. At least one PC must host the GV STRATUS Control Panel application. A designated PC on the control network hosts the SiteConfig application and the K2Config application.  



    Large GV STRATUS System
    A large GV STRATUS system is characterized by proxy stored on a dedicated Proxy Storage system. The Proxy Storage system is similar to a K2 Nearline configuration. The Proxy Storage system stores the low-resolution proxy media. One GV STRATUS Core Services server has the role of Proxy Serve. This Proxy Storage file system server provides a CIFS share that GV STRATUS client PCs mount for access to the proxy.

    This type of large GV STRATUS system is designed for a large-scale workflow and consists of a K2 online or production SAN, a Proxy Storage system, multiple GV STRATUS Core Services servers and multiple GV STRATUS client PCs. Client PCs that are connected to a corporate LAN or to the control network use a proxy media workflow. Client PCs that are connected to the media (iSCSI) network use a high-resolution media workflow. At least one PC must host the GV STRATUS Control Panel application. A designated PC on the control network hosts the SiteConfig application and the K2Config application.
