For Springpath/Hyperflex I’ve used VMware vSAN. The combination of Cisco and Springpath should deliver a one-in-a-box HCI solution (software/hardware/network/compute/storage/virtualization). 

However, after using the product for a while, I found the network integration is limited to the Fabric Interconnects and only during installation do you have the option to change network settings (other than normal operations). 
So it doesn’t deliver a complete HCI solution after all.
