Thinking of using a hardware VTEP (VXLAN Tunnel Endpoint) with VMware NSX? VMware recently announced Open Hardware Management Services (OHMS) , a project intended to help manage servers and switches in a software-defined data center (SDDC) context. What will happen when you combine GPUs and persistent storage? Servers/Hardware.
