I noticed this new SuperMicro VSAN Ready Node being published last week. The configuration is potentially a nice solution for ROBO deployments, primarily due to the cost of the system.

When I did the math it came in around $ 3800,-. This is the configuration:
- SuperMicro SuperServer 1018D-73MTF
- 1 x Intel E3-1270 V3 3.5GHz- Quadcore
- 32GB Memory
- 5 x 1TB 7200 RPM NL-SAS HDD
- 1 x 200GB Intel S3700 SSD
- LSI 2308 Disk controller
- 4 x 1GbE NIC port
It is a nice configuration that will allow for roughly fifteen 1 vCPU Virtual Machines with 3GB of memory and 60GB disk capacity per host. Personally I would use a different CPU and some more memory probably as that gives you a bit more headroom, especially during maintenance. The cost from a software point of view is socket based so you can increase memory and change the type of CPU with relative low cost impact. The SuperMicro server listed however is limited to the E3 CPU family and to 32GB but there are alternatives out there. (For instance the Dell R320 or maybe even the R210 etc)
From a software point of view the cost of this configuration is limited to 3 x VSAN license and 3 x vSphere. As VSAN even works with Essentials Plus and Standard you could leverage that to keep the cost down, but keep in mind that you won’t have DRS if you drop down to Standard or lower. Still sounds like a nice ROBO package to me, especially when you have many sites this could be a great way to create a standardized packaged solution.
