 \section{Results}
 
-We carried out performance measurements on a machine with an Intel Xeon
-E5-1630 at 3.7 GHz, Intel C612 chipset running openSUSE 13.1 with Linux
-3.11.10. The Xilinx VC709 evaluation board was plugged into one of the PCIe
-3.0 x8 slots. In case of FPGA-to-CPU data transfers, the software
-implementation is the one  described in~\cite{rota2015dma}.
+We carried out performance measurements on two different setups, described in
+table~\ref{table:setups}. In Setup 2, a low-end Supermicro X7SPA-HF-D525
+system was connected to a Netstor NA255A external PCIe enclosure. In both
+cases, a Xilinx VC709 evaluation board was plugged into a PCIe 3.0 x8 slots.
+In case of FPGA-to-CPU data transfers, the software implementation is the one
+described in~\cite{rota2015dma}.
