VSAN Stretched cluster protection between 6 AP countries

[lawjohn]

We are proposing N+2 solution to 6 countries (Asia Pacific) (with N+3 protection feature).

Requirement:

For 6 countries and each country with at least 4 nodes to form 1 cluster

Assuming N+2 protection, resource should be enough for workload in case of 2 countries failure**

Using VM VSAN std license ( no need for encryption and deduplication)

Hybrid node

FTT = 1 or 2 ( please count both FTT = 1 and 2 usable capacity)

Usable capacity for whole cluster = total usable backup storage/2

Two 10Gbps SFP+ port & 2 x 1GB RJ45 port for each node

Is it possible to do via VSAN Stretched cluster for the above mentioned protection?

I am not sure I am following you, you want to do a stretched cluster across countries but without a stretched license (Enterprise is required)? Or do you want to create 6 clusters, 1 cluster per country, and manage them from 1 location?

Keep in mind, you need to be able to hit 5ms RTT between the locations first of all. Secondly, a stretched cluster can only be between 2 locations (data) and requires a 3rd location as Witness.

Depping, many thx reply.  BTW, if this is not stretched cluster, any VMWare VSAN technology could satisfy requests for 6 sites? yes..if supported the requests, we can also propose to create 6 clusters, 1 cluster per country, and manage them from 1 location.  That means 1 Cluster need replicate at least another site cluster, not overlapped.  can do that?
