To move packets you need power, but how much can you draw from an interface? PCI Express Cards Consumption Limit PCIe has been around for a long time, since 2003, and many people know the maximum power draw of 75W per PCIe slot, but is it that simple? The short answer is no, but let’s have a look into the spec. It states that all cards can consume up to 3A on the 3.3 V power rail with the following restrictions applying: x1 cards: 0,5A on 12V, but overall consumption limit is 10W x4 – x16 cards: 2,1A on 12V, but overall consumption limit is 25W But

Stop Wobbling Around – A Salute From The MLE Embedded Lab

Stop Wobbling Around – A Salute From The MLE Embedded Lab Our Mission: If It Is Packets, We Make It Go Faster – today, how to properly mount those large FPGA-based PCIe Cards … theory and practice! Everyone working with evaluation hardware knows the struggles: On its own it works, but when you assemble an entire setup you have many loosely or weakly connected parts. This easily can damage a part or much worse, you spend an entire day debugging. To overcome this issue, MLE sometimes gets creative and designs additional carriers to securely mount extension cards or additional hardware. As a small example, the following images show a 3D Model of how we securely mount additional Hardware to the Xilinx ZCU102: SD-Mux, which we use to swap SD-Card images PCIe Card Here’s the theory: The stabilizations for PCIe and SD-Mux are 3D printed by our engineers (yes they have some neat toys at home). This helps MLE to have a clean stable lab setup. In this case we tested a SAS 12G storage controller on the Xilinx ZCU102. And the first prototype looks like this: If you want to enhance your Lab as well, we give you a kickstart.
