Powerstore NVME/TCP best practices

Hi there,

Are there any recommended NVMe/TCP settings or best practices for operating systems, particularly for VMware, similar to those for iSCSI? Additionally, does the VSI plugin apply these settings to ESXi hosts, or is there a roadmap for such integration? Furthermore, if 10GbE is intended for NVMe/TCP use, how does the RPQ process function?

thanks

Hi,

Thanks for your question.

These might help. https://dell.to/3UDX7Y8 and https://dell.to/4aUlYgg I don’t believe the VSI automatically applies settings. https://dell.to/3JGCAff it shouldn’t need rpq. https://dell.to/3WgMQCD

Let us know if you have any additional questions.

@DELL-Josh Cr​ Hi Josh,

Thanks for providing all the links; they're great. However, I couldn't find any recommended settings for NVMe/TCP on Dell's documentation. On another vendor's documentation for ESXi, I did come across a recommendation to enable 'delayed ack.' It would be helpful to know if Dell has any recommendations as well.

I also noticed a note from the 'NVMe/TCP Host/Storage Interoperability Simple Support Matrix,' which states that NVMe/TCP is capable of working on Ethernet switches with a link speed of 10GbE. However, Dell Technologies recommends 25GbE or higher. For any solutions involving 10GbE, it's advised to submit an RPQ.

Even if the switch meets the requirements as stated in https://dell.to/3WgMQCD , do we still need to submit an RPQ to run NVMe/TCP on a 10GbE network?

Thanks,

I don’t see any other best practices guides or info. Which switch are you using? If it meets all of the requirements you shouldn’t need to do an RPQ.

@DELL-Josh Cr​ Hi Josh, Thanks again. My question was more generic. In some environments, 25GbE may not be widely available, but NVMe/TCP might still be preferred over iSCSI, even on a 10GbE infrastructure.

Thanks,
