Intel NVME SR-IOV support

Hello

I am using P3600 Intel NVME. I am wondering whether they support SR-IOV. I am planning to run some performance isolation test on them on a virtualized environment.

Regards

Mania

Hi ManiaA,

 

 

We would like to inform you that our NVMe* Data Center drives are designed to be used with broad of the virtualization technologies in the market, and that includes SR-IOV.

 

 

Please let us know if there is something else we can assist you with.

That's Great. Could you please let me know, how can I enable it on device? Or do you have any documentation that I can use it to? I am using RedHat Rhel 7.1 and virt-manager.

Hi ManiaA,

We would like to inform you that there is no information how to set the SR-IOV since it is something you set up from the OS. You don't need to enable it from the SSD's site since it is ready for the feature.

We suggest you contact the https://access.redhat.com/community Red Hat* Linux* support community in order to get assistance how to set up SR-IOV in the OS.

Hi,

I am using RHEL 7.0 in that machine I have connected Mellanox Ethernet card and P3600 DS Intel NVME.

lspci -vvv showing Mellanox Ethernet card capabilities as

Capabilities: [108 v1] Single Root I/O Virtualization

 

(SR-IOV)

 

IOVCap: Migration-, Interrupt Message Number: 000

IOVCtl: Enable- Migration- Interrupt- MSE- ARIHierarchy+

 

IOVSta: Migration-

 

Initial VFs: 8, Total VFs: 8, Number of VFs: 0, Function Dependency Link: 00

 

VF offset: 1, stride: 1, Device ID: 1004

 

Supported Page Size: 000007ff, System Page Size: 00000001

 

Region 2: Memory at 00000000f7000000 (64-bit, prefetchable)

 

VF Migration: offset: 00000000, BIR: 0

But P3600 INTEL NVME does not showing SR-IOV capability.

This is not anything related to OS. Because Mellanox card is showing SR-IOV capability.

Please provide information any settings need to be done

Thanks

Hi 1ram,

We would like to inform you that the SSD is ready for the feature and you don't need to enable it in the SSD. This feature is related to the Ethernet Adapters, that's why your adapter is shown as SR-IOV compatible. You can check the https://software.intel.com/en-us/articles/single-root-inputoutput-virtualization-sr-iov-with-linux-c... article and use it as a reference.

We don't have any other documentation for SR-IOV in our SSDs. We recommend you to contact the https://community.redhat.com/centos-faq/ RedHat* support community in order to get the settings to enable the feature.

how can I comfirm the feature is implemented on INTEL SSD, since I don't see SRIOV capability on the SSD and there is no tech doc or web mentioning the feature on the SSD.

BTW:DC P4600 support the feature?
