TimeKeeper Grandmaster

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

VelaSync model

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.
