While Hyper-Converged Infrastructures such as Nutanix and VMware’s vSAN are popular topics in changing the dynamics of how compute and storage resources are consumed in a primary datacenter, one use case that sometimes gets overlooked is organizations that have or support a remote or branch office (referred to as ROBO going forward).
VMware addressed this customer need in the v6.1 release of vSAN supporting 2-Node + Witness configurations and has continued to introduce new enhancement/features since. Most recently the ability to “Direct Connect” the nodes in the ROBO location bypassing the need for a switch (at least for vSAN connectivity) to be deployed in v6.5.
While setting up vSAN via the vSphere Web Client is straightforward, there is a bit of “plumbing” that needs to be accomplished (both on the physical networking and ESXi networking side) to really get his use case up and running. Let’s see how it done!
