NVIDIA Hardware Capabilities and Limitations

Device	Capabilities and Limitations
NVIDIA Quantum	Supports both SHARP low latency and streaming aggregation operations. Supports up to 126 aggregation trees in the subnet (63 low latency trees, and 63 streaming aggregation trees). Note: The number of SHARP streaming aggregation operations is limited to one active tree per switch.
NVIDIA Quantum-2	Supports both SHARP low latency and streaming aggregation operations. Supports up to 1023 aggregation trees in the subnet (511 low latency trees, and 511 streaming aggregation trees). Note: Multiple SHARP streaming aggregation operations can be operated in parallel by a single Quantum-2 switch. The limit is one active tree per port.
ConnectX-6 and above	Supports both SHARP low latency and streaming aggregation operations.
