Explanation

Storing Solr indexes on local disk with separate mounts per SolrServer instance isolates I/O between instances, preventing one instance's disk activity from bottlenecking others - this is a core performance best practice for distributed search. RAID0 is recommended when maximum throughput and speed are the priority (striping across disks), while RAID5 balances performance with fault tolerance through parity - both configurations are appropriate depending on the availability requirements of the deployment. Option B is incorrect because the statement accurately reflects FusionInsight HD's official deployment guidance: shared disk without separation creates resource contention and single points of failure that degrade Solr performance at scale.

Memory tip: Think "one Solr, one disk" - dedicated mounts prevent "noisy neighbor" I/O interference, and RAID gives you the speed (RAID0) or safety net (RAID5) that a production search index demands.
