One more question on this. If I’m using real hardware and I make a raw device from a logical partition on the same physical disk as the OS. What’s your take on that vs the other scenarios?

We are running up against an upper limit with cache read-busy failures when we have many simultaneous requests for the same object that I was hoping that using a raw disk might fix (or give us a higher ceiling). Are there other things to consider when getting read-busy failures? Ah. Yeah, might help, not sure if it's going through a FS based image anyways... (through the HV). For sure your best bet is always (and I can't emphasize always enough) going to be direct IO to the raw device (no HV, no FS). -- Leif
