Balancing Input/Output

Use disk striping, random and sequential file disk access to balance Input/Output (I/O).

• Raw Devices
  On UNIX-like operating systems, you can create a database or dbspace on a raw device or a file system file.
• Disk Striping
  Striping data across multiple disks is an essential technique for good performance.
• Internal Striping
  Disk striping takes advantage of multiple disk spindles and provides the speed of parallel disk writes.
• Random and Sequential File Access
  Performance related to randomly accessed files can be improved by increasing the number of disk drives devoted to those files, and therefore, the number of operations per second performed against those files.
• Transaction and Message Logs
  Manage the size of the transaction and message logs to conserve disk space.
