Mean Time Between Failure – MTBF
AKCP is the oldest and largest data center environmental monitoring company in the world. Along the way we have introduced many hardware platforms and have learned many lessons. The SPX+ is our latest platform and incorporates our accumulated knowledge on how to build reliable, rugged embedded systems.
Since its recent release, the SPX+ has grown to an installed base of approximately 5,000 base units. On average we have 4 hardware failures per year that require RMA replacement. That is to say that the SPX+ is operating for 43,800,000 hours for every 4 failures. That is a MTBF of 10,950,000 hours. The sensors have an approximately similar record of durability.
The reason that this failure rate is so low is by design. The SPX+ was created for rugged environments. The components used in the SPX+ can withstand high-temperature environments because they generate very little heat. The SPX+ operates on 1 Watt of power. This stands in contrast to larger systems running more complex, and less reliable operating systems such as Linux.
Typical small computers often run at 300 Watts requiring a fan. The SPX+ doesn’t need fans or special cooling. The case is built from Aluminum, not plastic. The SPX+ has been tested in environmental chambers to be able to operate reliably at 70° C. During the manufacture every SPX+ is tested, then burned in for 96 hours in order to eliminate infant mortality. The system is put into stock awaiting a customer order.
AKCP is not only rugged in hardware, it is rugged in software. Rather than relying on large, untested, and unmaintainable open source projects, we write our own applications. This is more difficult but results in superior performance. We can maintain the code because we wrote it ourselves. If there is a bug that needs fixing, we can fix it. If there is a feature that needs adding. We can add it. This is not possible in larger systems relying on third-party applications.
Cellular Modem and Optional GPS The cellular data modem module gives the SPX+ ability to communicate over a cellular data network. An external antenna ensures a good signal can be received even if the SPX+ is inside a cabinet. Send SMS alerts directly from the SPX+ device, or connect it to our central monitoring platform, AKCPro Server, via a VPN connection. Cellular modems are available in 4G European and US bands. Optional GPS antenna can be added for geolocation of the device.
Internal UPS (4x AA rechargable batteries) This module provides backup internal power supplied by 4x AA rechargable batteries (batteries not included). Ideal for use in situations where poiwer may be unstable, to esnrue continued logging of data. Combine with a 3G or 4G modem for continued alerts even if your network is down.
