Effect of configuration on I/O activityThe configuration of your database server affects I/O activity.
Chunk and dbspace configurationThe number of disks that you use and the configuration of your chunks, dbspaces, and blobspaces affect the performance of your database server. You can improve performance by planning disk use and the configuration of chunks, dbspaces, and blobspaces.
Associate disk partitions with chunksYou should assign chunks to entire disk partitions. When a chunk coincides with a disk partition (or device), it is easy to track disk-space use, and you avoid errors caused by miscalculated offsets.
