Re: [dpdk-dev] Hi all, does Amazon VMs supported DPDK or not?

["Saha, Avik (AWS)" <aviksaha@amazon.com>]

I have only experimented with C3.8xlarge instances with DPDK. You have to attach at least 2 ENIs to the instances since one of them would be taken over by DPDK. Based on the size, you would be able to attach 8, 16  or 32 ENIs to the instances (these will be visible as ethn devices of ifconfig)

Let me know if this helps (or I am not getting the question :) )

Hi Shawn,

Which network interface is visible to the VM? I mean which is the virtual ethernet port is used in Amazon-VM-DPDK app? And what all interfaces are offered based on the VM size and requirements?

Thanks,
Rashmin

Yes, you can.

>From my colleague, Saha, Avik, they are running  IntelDPDK 1.7 on c3.8xlarges.

Thanks.

Hi Patel,

The customer consider that deploy DPDK application in Amazon VMs is very flexible and very easy global site deployment:

such as: they only need to buy a 2 lcores VM if a site only need 200Mbps throughput;   buy one 4 lcores VM if the throughput is 400Mbps;

the can buy different Amazon site VMs in US, German... for lower access latency;

It really depends on the devices offered in the VM. If direct device assignment is not provided to a VM or if the node hypervisor doesn't have an optimized para-virtual interface to a VM, I don't see any benefit using DPDK in VMs.

A customer plan to buy some global Amazon VMs to run their DPDK 1.3(will upgrade to DPDK1.6 or 1.7) based VPN applications on global sites.

Thanks a lot;
