• Vector data files should be stored on an HDFS location, separate from the default storage location, II_DATABASE. An II_HDFSDATA location is created by the installation process for this purpose.

• Backup files should be stored on an HDFS location, separate from the default backup location, II_CHECKPOINT. An II_HDFSBACKUP location is created by the installation process for this purpose.

• Work locations can be on local or HDFS storage. The local storage path will be created on each node. Also, an II_HDFSWORK location is created by the installation process for this purpose.

• The database wal directory is stored on HDFS and is accessible by all nodes.

• Data is distributed and replicated over the nodes by HDFS, influenced by the VectorH partitioning scheme.

• On the master node, the storage considerations are identical to those of Vector (standard Vector data paths).
