Hi, One of our customer have huge servers
- Bar-metal - 64 CPU - 512 Gb RAM - 6x2Tb disk in RAID 6 (so 2Tb disk space available) I think the best way to optimize resources usage of these servers is to install several Solr instances. I imagine 2 scenarios to be tested according to data volumes, update rate, request volume, ... Do not configure disks in RAID 6 but, leave 6 standard volumes (more space disk, more I/O available) Install 3 or 6 solr instances each one using 1 ou 2 disk volumes Obviously, replicate shards and verify replicates of a shard are not located on the same physical server. What I am not sure is how MMapDirectory will work with several Solr instances. Will off heap memory correctly managed and shared between several Solr instances ? Thank you for your advice. Dominique
