We have nine sites in a multi-site cluster with indexers at each site ranging from three to 15 servers. Each site's indexers are all on the same vlan and ip subnet for for their region. I have a need to expand one of the sites with more indexers but the vlan has run out of IP addresses. Is it possible to just create a new vlan to use a different IP subnet range and add these new indexers to the previously configured site? For example site2's indexers are in vlan 2 on ip subnet range 10.1.1.0/24. Can I add 6 new indexers to site2 with those new servers in vlan 3 on ip subnet range 11.1.1.0/24?
I looked over the documentation and didn't see a requirement indexers in a site for a multi-site cluster need to all be on the same vlan/ip subnet range but wanted to check if this is a legit configuration from real users in the community. Any pro's and con's? We currently have two independent search heads but are going to a search head cluster later this year.
thank you
