![]() My goal at the start of this effort was simple: Figure out what was needed to supplement the existing Open vSwitch deployment mechanism in OpenStack-Ansible to support DPDK. ![]() Below are some resources worth checking out: I can’t do it justice here, but there are many good resources on DPDK and its advantages. Originally envisioned by Intel, DPDK is now an open-source project under the Linux Foundation umbrella. These drivers, and applications that support them (such as OVS), allow network traffic to bypass the kernel in an attempt to decrease latency and increase the number of packets that can be processed by the host. However I guess I could always use the LSI controller in the pcie slot? I would really like to keep using freenas for the project.Īnyone who is also or have also faced this issue and eventually resolved it?Neutron ovs dpdk openstack proliant dl360e ubuntu rmrr openstack-ansibleĮarlier this year I made it a goal to spend more time on network virtualization technologies and software-defined networking, and have recently found myself attempting to build out an OpenStack environment using the Open vSwitch ML2 mechanism driver with support for DPDK.įor those that don’t know, DPDK stands for Data Plane Development Kit, and is a set of libraries and network controller drivers for fast packet processing. Trying this on the LSI card, they pull all 110-120MB/s without a hitch.Īs far as I could read, the CISS driver is relatively old, is there any alternative? I would love to use the onboard controller and on ubuntu it seems like the P420 has no problems working properly. ![]() Starting an erase of a second S3700 cuts the speed almost in half (30-35MB/s for each SSD). Erasing a single S3700 SSD cannot pull more than 60MB/s. Connecting the backplane to a LSI2008 pci card makes hot-swap work perfectly.Ģ) Write speeds are bad. the ciss driver detects a hot-swap event but does not initialize the drive as a "da-device". I have some questions/issues, there were some previous topics but none of them seem answered.ġ) Hot-swap does not work. I have updated all firmware and put the RAID controller into HBA mode. The server has an intergrated P420i RAID controller. ![]() I am looking at installing a newly acquired D元80p 25SFF server as my new freenas SSD box. ![]()
