HyperFlex Edge Cluster questions

[m1xed0s]

Hi, 

I am trying to refresh my knowledge of the HX Edge cluster, like sizing and scalability etc. But here are some of my confusion that hope get some insights here.

1. I was not aware of "DC-no-FI" cluster until I read the link below. But it does not seem like the DC-no-FI cluster the same as edge cluster? If so, what would be the difference?

2. Document shows HX Edge cluster supports up to 4-node. But can compute-only nodes work with HX Edge cluster? If so, what is truely the max number of nodes in a HX Edge cluster with 10/25Gbps connectivity?

Hi @m1xed0s ,

Correct. "the DC-no-FI cluster IS the same as edge cluster". Documentation is scarce, but this tell you a little and this is the ordering guide 

If so, what would be the difference?

I'd need to check - but I think the larger (4-8 nodes) requires a higher licence

2. Document shows HX Edge cluster supports up to 4-node. But can compute-only nodes work with HX Edge cluster?

NO

Thanks for the info. But if "DC-no-FI" cluster is the same as Edge cluster, why they even introduced the term...

LOL. I'm sure you know the answer = "Different Market", but the thing I find amazing is that they couldn't find a decent term to describe it.  For a while it was referred to as "BYO Switch" (Bring You Own Switch) - but clearly that didn't go to press.

But "DC-no-FI" ? - what a mouthful!

Yeah…I vaguely remember someone from Cisco mentioned “Bring You Own Switch”…
