Unsupported

A little while ago I replaced my three ageing Intel NUC hosts with a single (still ageing) Dell T7500 workstation. The workstation provides 24 processor cores and 96GB RAM for a really reasonable price, while still being quiet enough to sit in my home office. One of the driving factors in retiring the old NUCs was vSAN - I know in the newer generations of NUC you can get an M2 and a SATA SSD in, but my 1st gen. models could only do a single M2.

This article originally started off life as a record of how I managed to get this working, as a lot of my posts do, but this time it appears I am foiled.

Last week, I had 3 vCenter Servers that appeared to be happily talking to each other in Linked Mode sharing a singe Multi-site SSO domain without any real issues. I had a single-pane-of-glass view of all 3 and I could manage them all from the one client. The reason for the 3 vCenter servers was segregation of LAN and DMZ networks: vCenter001 was in the LAN, vCenter002 sat in DMZ1 and vCenter003 sat in DMZ2.
