Hyperflex/ESXi hardening

[rjohnson5]

Hello

Im running a Hyperflex cluster with ESXi.  I was just wondering if there any guidelines on how to harden the ESXi environment thats specific for Hyperflex.  For example, i dont want to just follow the VMware hardening guides if Hyperflex requires port 22 to be open at all times.
