Now that you’ve seen how TimeKeeper acts as a client (see the “TimeKeeper Client” section) and then serves that time as a server (see the “Timekeeper Server” section), we can now look at how these features come together in the TimeKeeper Grandmaster Generation 2 appliance.
An appliance integrates TimeKeeper’s features on a tested platform, and adds a number of features to provide a simple out of the box solution for users. These added features include:
- Integrated GPS receiver with support for multiple constellations
- High quality oscillator with 4us/day holdover, or a Rubidium option for 0.6us/day holdover
- Multiple 1G network interfaces
- Multiple 10G/25G network interfaces
- Reference PPS input
- Redundant storage (RAID)
- Redundant power supplies
- IPMI interface for out of band management and control
- Integrated PPS and 10MHz outputs
The Grandmaster uses a standard 1U platform:
Having an integrated device also allows for more capable software tools, including:
- SNMP query support
- User authentication via RADIUS or TACACS+
- Web interface via both HTTP and HTTPS
- Support for user-configured VLANs
- Support for user-configured bonded network devices
- Advanced routing capabilities
- Field upgradeable - get software improvements and updates over time

The FSMLabs Grandmaster is a drop-in replacement for many other Grandmaster models, including the Spectracom VelaSync. Note that FSMLabs no longer allows Spectracom/Orolia to manufacture TimeKeeper based Grandmaster appliances and is instead providing sales and support for VelaSync systems directly and via its resellers.
