The main reason that I went with the Dell R710s was due to the supportability of ESXi 6.0, the quad port nics, and it doesn’t hurt that they are quiet, in fact they aren’t much louder than my desktop. I opted out of the HP servers, for no particular reason, and the C6100 because I have heard that thing is so loud you can hear it a couple rooms down. The drobo NAS was a recommendation of my colleague. I opted to try it out over Synology or Qnap based on that recommendation and price as I wanted SSD caching and it seemed to add around $300 to the synology setup over Drobo. This thing is pretty slick as you can mix or match the drives and even upgrade an individual drive on the fly. As far as the Alcatel switch, one of my colleagues, Tom Rumland, provided this L3 switch for free a six pack of beer ☺ how could I pass that up?
 

Design Considerations

 
I decided not to nest my ESXi hosts on the R710s and instead use them as bare metal hypervisors. I went this route as I wanted to have good performance, wanted a more real world lab, and because of various VLAN considerations when nesting. As you can see, I only have one cluster that is a combination of Management, Compute, and Edge workloads, therefore both will be prepared for DFW and VXLAN.

Since I had quad port nics, I had enough flexibility to split out my traffic into 4 VLANs – Management, vMotion, storage and VXLAN. Each has their own vmnic, and the others are being used for standby redundancy as I ended up trunking all of the interfaces.

As far as the toplogy, I have started out very basic. I am running one Edge device and one DLR with OSPF. I am going to write more posts on configuring ECMP, multitenancy, and multisite/cross vCenter NSX, and even DR toplogies in the future but wanted to keep it simple for now.

The finished product is below! I know its not pretty right now, I still need to order a rack solution and haven’t decided what I want. So far everything seems to be running awesome! I have a ton of available RAM to use for future growth which I am not typically used to since I was always running on a desktop, or an internal cloud environment. If anyone has any questions about my setup, wants more details, or needs assistance setting up their own lab please feel free to comment below!
