So I might be looking for another VPS provider. They sent me a ticket in the middle of the night saying one of my servers would be taken offline due to an emergency hardware issue. Not to be a backseat DC admin but, the hardware issue couldn't have affected SAN networking because the machine was still functioning (I suppose it could have been degraded without me knowing) and accessible. It was down for 30 minutes.

Why couldn't they drain the vm to another cluster node?

I wondering if I have a more competent rack in my closet then most VPS providers do. I'm going on %99.99 uptime since I built it, and I've had hardware failures that have taken machines offline. It's called a cluster for a reason.
