Single index - multiple SOLR instances
Hello,
Is it possible to have the index created by a single SOLR instance, but have
several SOLR instances field the search queries. Or do I HAVE to replicate
the index for each SOLR instance that I want to answer queries? I need to
set up a fail-over instance. Thanks

OK. Of course, you'll have to make sure everything on the SAN is redundant (down to controllers, power supplies, etc.) and that the disks can handle that high query load/IO.

Thanks, Otis. That is great, as I plan to place the index on NAS and make it
writable to a single solr instance (write load is not heavy) and readable by
many solr instances to handle fail-over and also share the query load (query
load can be high)

Ashok,
You can put your index on any kind of shared storage - SAN, NAS, NFS (this one is not recommended). That will let you point all your Solr instances to a single copy of your index. Of course, you will want to test performance to ensure the network is not slowing things down too much, if there is network in the picture.
