I have 2 sites configured with a multisite cluster.
Site 1: Indexer, manager, independent search head.
Site 1: Indexer, independent search head.
I am looking for a way to have all user's searches and lookups synchronized to both search heads, and it looks like a search head cluster is the way to go.
First question:
I am having a little trouble grasping the cluster+affinity and how it applies to a search cluster.
My bandwidth between sites is quite low, and i do NOT want a site1 searchhead searching site2 and vice versa.
If I leave affinity active and run a search at site1, does the search take place ONLY on the site1 searchhead against the site1 peer?
Or is the search distributed across the 2 sites, even though it is only using the site1 index as the index to search?
Second question:
I have no need for a 3rd search head. I don't have dedicated hardware, I don't need more resources, etc.
But, I know that the search cluster needs 3 searchheads.
Can I add a second searchhead at site1 to be the third, but leave it severely underpowered? A small dual core VM whose only purpose is to provide a 3rd member.
If I do this and perform a search at site1, will it attempt to search using both the strong and weak search head and slow me down?
What it comes down to is that I do not need the full "cluster", I just need to keep my user data replicated. It seems that the cluster is the best way to accomplish this, even though it adds complexity.
