Hi, The specification I came up with is for both GridMon and PerfSonar is below. My logic was to have a reasonably spec'd device which would meet any of the monitoring requirements that we may have to support over the coming 3 - 5 years. The device can support a 10 Gigabit interface if required. However, there is a cheaper solution to this which is the Dell R610 for PerfSonar. The device is approximately £300 cheaper than the R410 below. It too can support a 10 Gigabit interface. It is theoretically possible that this device could also be used as the Gridmon client as well. Therefore, could we have a quick discussion on which device we wish to buy as we should have a standardised model across the UK for these devices.
