Quantum Spark appliances have a much smaller footprint than the bigger appliances or open server hardware. Mostly Flash based and with 2GB RAM, the OS is much smaller, has a different kernel and processes. Even if there is a R81.x firmware release it will still be only the smaller brother/sister with limited capabilities. This is the low end, sufficient for small companies and with a much lower price tag. Although the 1800 even has a HDD instead of the flash based disk usually found with SMBs, it still is not able to run GAiA and the full CP software blades, as it always relies on an Embedded GAiA firmware image.
