SPD Engine Disk I/O Setup
The Scalable Performance Data Engine (SPD Engine) may use up to four different areas to store user data and other information.
These four areas are:
In order to maximize your scalability and performance with the SPD Engine, it is important that you give careful thought to how
you allocate space and disk resources to the four areas listed above. A "Quick Guide to SPD Engine Disk-I/O Set-Up"
available in PDF
gives guidelines on how to configure your
hardware resources in order to get the best performance from the SPD Engine. Information is given to allow you to determine the
amount of space that needs to be allocated to the various areas. The pros and cons of different RAID groups for each of the
different types of areas are described. In addition, a program is provided that can be run after you have allocated your
hardware resources to help you determine if you have properly configured your SPD Engine enviroment.
