Unity L1 Configuration
One question that always arises regarding multi-board setup: how to deliver the actual incoming data to all FPGA boards simultaneously? Crucial if FPGAs are supposed to handle the same data, for example, in load-balanced schemas or running different strategies on the same feeds.
The LDA Unity platform easily solves this problem by installing one D6 Mark II PCIe form factor full mesh Layer 1 switch-on-card in place of one FPGA board.
With this option, each Unity chassis gets its own full mesh Layer 1 network with uniform latency to all nodes, so all external data can be delivered in under 2 ns to each FPGA board. FPGA boards can then send data to the exchange independently or use Layer 1 again: full flexibility is provided.
