Next to acquiring individual nodes Cisco also offers a bundle that is aimed at small ROBO deployments, HyperFlex Edge.
Previously Cisco HyperFlex Edge clusters consisted of 3 HX220x Edge M5 hybrid nodes with 1GbE or 10GbE connectivity. This configuration couldnt be expanded.
HX 4.0 introduces Cisco HyperFlex Edge clusters consisting of 2, 3 or 4 HX220x Edge M5 all-flash nodes with 1GbE or 10GbE connectivity. 2 node clusters are monitored by Cisco Intersight Invisible Cloud Witness, eliminating the need for witness VMs and the infrastructure to manage those VMs as well as life cycle management.
