Hi every one
we have 3 data centers or better to say server farms in different geo locations. A main center including many servers and the WAN and Internet central point (Traffic from there goes to and comes from Internet). The two other centers also include some servers serving the local site, other sites and also play the role of backup and disaster recovery servers in case of a disaster in main site. Those two sites also have WAN (Intranet) and wireless connections to the main site.
I'm designing and implementing NSX for the whole infrastructure to the extent possible. Now I have some questions which seek and appreciate the answers and any other consideration you may have
I have a couple of VLAN's which is good If I can extend and have them in different sites. (We have some old Novel apps which work in IPX so it's desirable to have them extended in all sites so they can be in a VLAN/VXLAN L2 domain and interact with each other.
I am not interested in having separate vcenters and nsx managers in different sites. I just may deploy another fail-over vcenter appliance in second site.
1- Should I install Universal DLR or not? If yes, one (or two) for each data center or just one (or two) for the whole infrastructure
2- If universal DLR is not needed and I just should have DLR's, Should I have instances (one or two) for each data center or one (or two) for all data centers? I'm asking this because when I install DLR it askes to choose a data center. Let's say again that I have VM's in different sites which I like to be in the same VXLAN if possible
3- Each site has east-west traffic in its data center, traffic from local VM's to VM's in other sites which the latter normally goes to physical network (core switches and routers ) then over wireless and WAN links to the other site. Do I need edge service gateways to accomplish this or DLR's are enough?
4- In the main site we have connections to Internet so we need one or more DMZ area. Is it a good choice to have two ESG's to separate these?
5- What transport zones I need? one for the whole datacenters including DMZ clusters, one for all datacenters except DMZ and one including DMZ's? or better decisions can be made?
6- Some sources say install controllers in management cluster! Is this right? I have management cluster including my main vcenter server and NSX managers but controllers are installed in operational data center.
Sorry for long post and thanks in advance for any help
