A couple of notes to this:
Ideally you should have at least 2 more failure domains than your base
resilience (K+M for EC or size=N for replicated) - reasoning: Maintenance
needs to be performed so chances are every now and then you take a host
down for a few hours or possibly days to do some
The larger the value of K relative to M, the more efficient the raw :: usable
ratio ends up.
There are tradeoffs and caveats. Here are some of my thoughts; if I’m off-base
here, I welcome enlightenment.
When possible, it’s ideal to have at least K+M failure domains — often racks,
Hi,
It depends of hardware, failure domain, use case, overhead.
I don’t see an easy way to chose k and m values.
