The current set of nodes supported by Barbara have a hardware architecture from the x86_64, armv6, armv7 or aarch64 (arm64) families, although the Barbara team and its partners are progressively adding new models of equipment from different manufacturers. The decision to use one node or another will depend mainly on the communications and power required for the specific use case.
S Family: Small Gateways
Affordable and efficient
Based on ARM processors with or without graphics acceleration.
M Family: Medium-sized Gateways
Good balance for non-demanding aplications
Based on Atom/Celeron processors with or without graphics acceleration.
L Family: Large Gateways
Power and performance
Based on i3/i5/i7 processors with or without graphics
XL Family: Extra Large Servers
Maximum power and durability
Based on i9/Xeon processors with or without graphic acceleration.
