The term you = called "ENI" is new to me, so what kind of device is it? It must be one of = this: 1. Emulated Device (I suspect this is the one; because DPDK API works witho= ut any change) 2. Para-virtual Device 3. Directly Assigned Device 4. Fully customized Device (i.e shared memory with GrantTable mechanism) or 5. A generic wrapper device (covering all of the above devices) Thanks, Rashmin -----Original Message----- From: Saha, Avik (AWS) [mailto:aviksaha@amazon.com]=20 Sent: Tuesday, September 30, 2014 10:49 AM To: Patel, Rashmin N; Wang, Shawn; Dong, Binghua; dev@dpdk.org Subject: RE: Hi all, does Amazon VMs supported DPDK or not? I have only experimented with C3.8xlarge instances with DPDK. You have to a= ttach at least 2 ENIs to the instances since one of them would be taken ove= r 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 :) ) Avik -----Original Message----- From: Patel, Rashmin N [mailto:rashmin.n.patel@intel.com]=20 Sent: Monday, September 29, 2014 1:54 PM To: Wang, Shawn; Dong, Binghua; dev@dpdk.org; Saha, Avik (AWS) Subject: RE: Hi all, does Amazon VMs supported DPDK or not?

Hi Patel, The customer consider that deploy DPDK application in Amazon VMs is very fl= exible and very easy global site deployment: such as: they only need to buy a 2 lcores VM if a site only need 200Mbps th= roughput; buy one 4 lcores VM if the throughput is 400Mbps; the can buy different Amazon site VMs in US, German... for lower access lat= ency; -----Original Message----- From: Patel, Rashmin N Sent: Saturday, September 27, 2014 12:41 AM To: Dong, Binghua; dev@dpdk.org Subject: RE: Hi all, does Amazon VMs supported DPDK or not? It really depends on the devices offered in the VM. If direct device assign= ment is not provided to a VM or if the node hypervisor doesn't have an opti= mized para-virtual interface to a VM, I don't see any benefit using DPDK in= VMs. -----Original Message----- From: dev [mailto:dev-bounces@dpdk.org] On Behalf Of Dong, Binghua Sent: Friday, September 26, 2014 5:47 AM To: dev@dpdk.org Subject: [dpdk-dev] Hi all, does Amazon VMs supported DPDK or not?
