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 about disk striping
and RAID, see “SPD Engine Disk
I/O Setup” in Scalability
and Performance at
http://support.sas.com/rnd/scalability/spde/setup.html.
Note: If you are using Hadoop Distributed
File System (HDFS) for storage, see SAS SPD Engine: Storing Data in the Hadoop Distributed File System.
