Max Cluster Size for Hyperflex Nodes

[david.moy1]

Hi,

Is there a max cluster size for 220c and 240c M4 HX Nodes? I beleive it used to be 8. Does that still hold true with the 2.0 update?

As per the following doc updated in Dec 2016 it is still 8 "Cisco HyperFlex clusters currently scale up from a minimum of 3 to a maximum of 8 converged nodes per cluster, i.e. 8 nodes providing storage resources to the HX Distributed Filesystem. For the compute intensive “hybrid” design, a configuration with 3-8 Cisco HX240c M4SX model servers can be combined with up to 4 Cisco B200 M4 blades, called compute-only nodes. The number of compute-only nodes cannot exceed the number of converged nodes.

Once the maximum size of a cluster has been reached, the environment can be “scaled out” by adding additional servers to the Cisco UCS domain, installing an additional HyperFlex cluster on them, and controlling them via the same vCenter server. A maximum of 4 HyperFlex clusters can be managed by a single vCenter server, therefore the maximum size of a single HyperFlex environment is 32 converged nodes, plus up to 16 additional compute-only blades."

I haven't seen a node increase for the upcoming 2.0 

However, the current max support is a 16-node cluster that is broken down as follows: 

• 8 converged nodes (hx220c, hx240c)
• 8 compute nodes (c220 m4, c240 m4, b200 m4)
