Storage locations on HDFS

You can place storage locations in HDFS, in addition to on the local Linux file system. Because HDFS storage locations are not local, querying them can be slower. You might use HDFS storage locations for lower-priority data or data that is rarely queried (cold data). Moving lower-priority data to HDFS frees space on your Vertica cluster for higher-priority data.

If you are using Vertica for SQL on Apache Hadoop, you typically place storage locations only on HDFS.
