Intel NVME SR-IOV support

[MAbdi]

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.

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?

Hi A Taylor, our SSD's do not support SRIOV. Sorry for the confusion.

Thanks,
