Hi,
I don't really have the need for speed regarding the title, but I can't help wondering what would be the most efficient (and maybe fastest) way to share an array across multiple VM/LXC guests.
I am asking as I currently rely on a Linux Bridge which does not attach to physical port for transferring data among the VMs. This bridge is applied as an adapter inside a router VM (IPFire) which links to its DHCP server. In this case, via iPerf3, I could get up to ~ 22 Gbps of transfer among the guests. This is probably not the best practice but maybe the simplest to implement. Interestingly, I have seen this number (22 Gbps) on two different hosts with different CPU/MB and router OS, so I was guessing this limit might come from Proxmox (kindly correct me if I am wrong).
22 Gbps is a lot for my current harddisk RAID 6 array, but if I am moving to a high speed NVMe RAID (say it reaches > 22 Gbps), how should this be done?
One possible use case is that if one needs to run data acquisition on a Windows guest, and data is stored onto the NVMe SSD RAID, which is later further analysed by a Linux guest. A fast SSD storage accessible by multiple VMs simultaneously will be desired.
