VSAN new feature

Hi Vmware Experts

we have a situation that we build more than 20 node as VSAN cluster

right now as all of you know that the hardware itself improve and the prices also getting better

for example network card or disks itself

anyway our 20 nodes cluster having 10 G interfaces but now we need faster

but we cannot extend our cluster with nodes has higher network interfaces

so here come an idea to start to build a separate cluster with our new servers but we will lose the nice feature for VSAN for scale up

so one of my collages ask me if we can build multi VSAN cluster but we let all three VSAN cluster to see each other data store

but not via iscsi or NFS he asks if Vmware VSAN has a feature that if under one data center you have multi VSAN cluster and all of them can access the multi VSAN data store based on VSAN FS not iscsi or NFS

i think this is not logical and not possible but he said Vmware one day should provide such solution

anyone of you have any idea about such question

Maximum number of nodes per vSAN is 64 ESXi Hosts.

What's the issue here with

HI Andrew

we know that the Max node 64 node

but our new 6 servers has 40 G netowrk interfaces

yes i know we can add them to our cluster but we will lose the speed of 40 G because the old servers has only 10 G

for this i asked the question about having ability to build multi VSAN clusters under one data-center with ability to access every VSAN cluster data store from each VSAN cluster but without using iscsi or NFS
