I like to concept of Hyperconverged Infrastructure (HCI) as it is commodity hardware with:
- virtualised computing(a hypervisor
- virtualised SAN (software-defined storage)
- virtualised networking (software-defined networking) with some solutions

In Gartner Magic Quadrant we have the following:
Nutanix - Appliance: Virtualisation, storage, self service
VMware Cloud Foundation (vSphere/vSAN/NSX) - on any certified hardware or cloud
Dell EMC VxRail - Appliance jointly engineered by VMware and Dell EMC with single vendor for support.
HPE Simplivity - Appliance: Virtualisation, storage, backup, replication
I love the concept of virtualised NSX networking where it creates a layer 2 overlay network on top of standard layer 3 network then everything is created on the overlay network including switches, load balancers and distributed firewalls. There is a choice of using NSX supplied firewall/load balancer (included in NSX) or choose existing products such as both Palo Alto and F5 which support virtual appliances on top of NSX.
VMware Cloud Foundation has gained significant market share. Here is pricing:
The other alternative to HCI is for enterprise IT to consolidate data center and use commodity and low cost infrastructure...significantly lower in cost. The following is my design for 4 rack pod:
*Backup Appliance = http://www.hgst.com/products/platforms/ultrastar-serv60-8 with RHEL 7.5 dedupe. Alternative HPE Apollo 4510 (720TB), HPE StoreEasy 1600 (64TB), HPE Apollo 4200 (288TB @ $AU$30K)
**Most expensive will be networking hardware (some examples firewalls deployed in pairs each at $300K), load balancers, switches
