The minimum number of disks is determined by the amount of storage space required and the I/O throughput requirement. You will also likely need storage space for a data staging area on a fast RAID array to load data into Vector. Also be sure to take into consideration the expected database growth with the expected challenge of extending the file system if and when you need more storage space for your database.

The Vector database can be stored across multiple storage locations to allow for data expansion, or to allow different types of data to be stored on different types of storage. For example, you may want to store temporary space on faster storage than data.
