nvme/tcp

One more GX10 post, the last one for now. After battling the black screen, the hard resets and the power cap, we were finally able to see what this box and PVE on arm64 can do. Out of the box, the kernel initiator managed NVMe/TCP reads at 6.3 GB/s. Two kernel parameters later it was 28.1 GB/s...

Hello Community, im currently in the progress of trying out nvme over tcp in Proxmox VE and wanted to ask, if somebody has ressources for: * Basic Setup of NVMe-Over-TCP in Proxmox VE? * Information about using basic nvme-cli vs nvme-stas -> benefits? * Measuring performance of nvme-over-tcp...

!!! 1.Hint: This Thread is not for Ceph fan boys. Go away! !!!! Occasion: In the Thread zfs-over-iscsi HA Storage solution my one (the word "one" is always related to a human being, not a matter or person or number) mentioned that zfs-over-iscsi is not the best protocol stack for NVMEs. So the...

I have a proxmox cluster of 5 hosts with a shared SAN. The SAN exposes a number of volumes over NVMe/tcp and it all works fine. The issue I have is when I add a new volume on the SAN, I initialise the volume group on one pve node, then the other nodes do not see the new vg without a reboot...

I have configured shared storage for Proxmox using a Dell PowerStore 1200T. The protocol in use is NVMe over TCP. Everything works fine, except the connection does not persist after a reboot. discovery.conf Configuration: --transport=tcp --traddr=192.168.5.5 --trsvcid=4420 --transport=tcp...

Hello Everyone. We received excellent feedback from the previous storage performance investigations, particularly the technotes on optimal disk configuration settings (i.e., aio native, io_uring, and iothreads) and the deep dive into optimizing guest storage latency. Several community members...
