Yes MSA2050 and MSA2052 pure Virtual Array. There is no linear concept any more from Gen 5 MSA array.
I would never suggest you to disable threshold alert (not sure if possible or not as don't see any such command to do this). You can modify the limit % but can't disable I guess.
You can check MSA 2050 Quickspec to get details about the product,
