Multi Hypervisor Zone/Pod

I have a probably stupid question. If I have a single zone, single pod infrastructure that has two clusters, one that's XenServer and one that's VMware, I assume I will need to download both systemVM templates correct? ACS will know which template for which? And also I assume that a user could have a machine in each cluster and still be in the same "LAN" or not?

I have not used ACS with heterogeneous clusters in the same POD.. Thank you for the help.

Hi Marty,

Don’t worry, not a stupid question :-)

Yes you should download both system VM templates when you seed your secondary storage, and yes ACS knows which template to use for each hypervisor. 

With regards to networking – as  long as the same VLANs (assuming you are using VLANs) are presented to both clusters and correct trunking is configured on the switches in between – then yes a user can have VMs on each hypervisor and have them communicate. The VR for an isolated network will obviously live on one or the other hypervisor, so VMs on the opposite hypervisor will need to traverse the network on the isolated guest network VLAN to hit it’s default gateway.
