-It is already possible. You can use the addreplica Collection API with a
custom dataDir.-
Ah I see you have already seen the collection API, my bad. What are you
expecting of Solr? Do you want to e.g. configure multiple data dir paths for a
Solr node and have Solr allocate shards taking that into account?

> Multiple data dirs
> ------------------
>
> Key: SOLR-7256
> URL: https://issues.apache.org/jira/browse/SOLR-7256
> Project: Solr
> Issue Type: New Feature
> Affects Versions: 4.10.3
> Environment: HDP 2.2 / HDP Search
> Reporter: Hari Sekhon
>
> Request to support multiple dataDirs as indexing a large collection fills up
> only one of many disks in modern servers (think colocating on Hadoop servers
> with many disks).
> While HDFS is another alternative, it results in poor performance and index
> corruption under high online indexing loads (SOLR-7255).
> While it should be possible to do multiple cores with different dataDirs,
> that could be very difficult to manage and not humanly scale well, so I think
> Solr should support use of multiple dataDirs natively.
