GV STRATUS server
The GV STRATUS server hosts the software services and databases of the GV STRATUS system.
There can be one or more GV STRATUS servers in a GV STRATUS system, with services and
databases distributed across servers as appropriate for the size of the system. For smaller GV
STRATUS systems, the GV STRATUS Express server can also store low-resolution proxy media.
Components that can reside on a GV STRATUS server include the following:
• License management — Services that manage the assignment of licenses and roles to groups and
users.
• User preferences — The settings you make in the STRATUS application. When you log in to
the GV STRATUS application with the same credentials, the settings you make on one PC are
available on other PCs.
• Proxy Server — Services that manage the location of proxy media and the GV STRATUS
application's access to the proxy media.
• Databases — Includes information for the following:
• Media asset management
• Metadata
• Rules
• Transfers
• Aurora Playout SDB (Simple Database)
• Scheduler
• Rules Engine
• Workflow Engine
• MDI — MDI is the acronym for Managed Device Interface. An MDI is a software component
that provides an interface for the GV STRATUS database to access a device. Typically these are
devices on which media resides, such as K2 systems, NAS devices, and archive devices. Each
type of device has its own MDI. For most MDIs, the MDI software component is hosted on the
GV STRATUS Core server, rather than being hosted on the same machine that it accesses. MDIs
include the following:
• Summit Standalone
• Summit SAN
• Proxy Encoder
• DIVA
• FlashNet
• Generic FTP
