Creating and Loading SPD Engine Files

Efficiency Using Disk Striping and Large Disk Arrays

Your system might have a file creation utility that enables you to override the file system limitations and create file systems (volumes) greater than the space on a single disk. You can use this utility to allocate SPD Engine libraries that span multiple disk devices, such as RAID. RAID configurations use a technique called disk striping that can significantly enhance I/O. For more information on disk striping and RAIDS, see "SPD Engine Disk I/O Setup" in Scalability and Performance at http://support.sas.com/rnd/scalability/spde/setup.html.
