Communication benchmarks with the Ancor Fibre Channel Fabric
We performed two kind of experiments based on three active machines connected around the switch. The first one consists of one machine (the most powerful) acting as a sender and the two other machines acting as receivers alternatively. The second one consists of one machine (always the most powerful) acting as a receiver and two machines acting as senders alternatively. For both experiments, Read/Write in a non blocking mode and in a blocking mode have been tested and results are reported hereinafter.
For all the charts displayed in this paragraph, the legend is as follows:
- case of two senders and a receiver:
The theoretical performance curve of the sender1 (respectively sender2) was obtained by measuring the performance of the sender1 (respectively sender2) when transferring some data to the receiver, without any other machine interfering on the network (results of paragraph III.A.). The theoretical performance curve of the receiver has been inferred from the theoretical performance curves of the sender1 and the sender2. The maximum theoretical speed of an optic fibre was indicated only on one graph to recall the uppermost limit towards which the experimental results could tend.
Similarly, the theoretical performance curve of the receiver1 (respectively receiver2) was obtained by measuring the performance of the receiver1 (respectively receiver2) when receiving some data from the sender, without any other machine interfering on the network.
As previously for communications between two machines, figures a display the speed performance, figures b the communication time, and figures c the percentage of CPU time consumed in the measured aggregate communication time.
