Hi, We are about to size large environment with 7 nodes/servers with replication factor 2 of SolrCloud cluster (using Solr 7.6).
The system contains parent-child (nested documents) schema, and about to have 40M parent docs with 50-80 child docs each (in total 2-3.2B Solr docs). We have a use case that will require to update parent document fields triggered by an application flow (with re-indexing or atomic/partial update approach, that will probably require to upgrade to Solr 8.1.1 that supports this feature and contains some fixes in nested docs handling area). Since these updates might be quite heavy from IOPS perspective, we would like to make sure that the IO hardware and RAID configuration are optimized (r/w ratio of 50% read and 50% write, to allow balanced search and update flows). Can someone share similar scale/use- case/deployment RAID level configuration ? (I assume that RAID5&6 are not an option due to parity/dual parity heavy impact on write operations, so it leaves RAID 0, 1 or 10).
