I think Lustre works fairly well. At the very least, it's used in a lot of HPC centers to handle large filesystems that get hammered by lots of nodes concurrently. It's open source so nominally free although getting a support contract from specialized consulting firm might be pricey.

You're going to have to open the image and then go to the third image. I thought it was interesting that OCI pegs Lustre at 8Gb/s and their high performance FS at much higher than that... 20-80.

		That's 8Gb/s per TB of storage. The bandwidth is going to scale up as you add OSTs and OSSs. The OCI FS maxes at 80Gb/s per mount target.
