Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

We're going to build a cloud infrastructure and would like to use the HP DL160 G8 with a 20GE NIC (2x10GE LACP).

How much RAM and CPU can handle this NIC?

The server will have at least 2x Intel E5-2640 and 256 GB RAM. The maximum amount of RAM is 768GB.

We want to use this Infrastructue for usual Customers as Privat/Public Cloud Solution.

Thanks

Your question doesn't really make sense, but I'm going to try and give you a straight cut answer anyway.

Assuming you're using the NC523SFP (big assumption), these (as does every 10Gb NIC I've ever seen) have an offload engine. Some even have such powerful processors they have a fan on their substantial heatsinks.

This takes processing load off the main processor, which means that you should be able to saturate your 20Gb/s of bandwidth (if you can even generate that much data) with only dedicating a minimum of your processor time to it.

(for what it's worth, it's difficult to saturate even a single 10Gb link).

Hey, sorry for my bad English(( Anyways, we think that our cloud will generate enough data! If a customer have a heavy application which requires lots of RAM (let's say database) and need to caching ~1TB, you think that just 10GE would be enough? –  Baloo Jan 18 '13 at 3:22

Sigh. Why would the RAM requirements of a database have anything to do with the bandwidth of the network? –  mfinni Jan 18 '13 at 4:01
