LaGrange is the codename for a POWER9 CPU module/package; it represents a middle ground between the PCIe-only peripheral connectivity of the the Sforza module, and the maximum OpenCAPI/NVLink connectivity of the Monza module. However, LaGrange also has twice the Xbus (socket-socket) bandwidth of these modules.

LaGrange is used by the Google/Rackspace Zaius/Barreleye G2 board.

LaGrange will be used for the upcoming RCS Condor board, albeit in a single-socket configuration.
