SPDS是引擎么？没用过啊，能否举个例子，给我们讲解一下，谢谢！

SPD Server
The Scalable Performance Data Server (SPD Server) is a client/server, multi-user data server designed to optimize storage and to speed the processing of large SAS data sets. SPD Server does this by parallelizing many of the SAS I/O functions such as WHERE processing and INDEX creation over multiple data partitions in the same way that the SPD Engine works. However, SPD Server extends parallel capabilities to include GROUP BY processing and SQL passthru. SPD Server requires an SMP machine and is designed to use all resources available on the machine to achieve maximum scalability. The maximum benefit with SPD Server is gained when it is run on a machine with:
multiple cpus
multiple I/O channels
multiple disks
large amount of data to be partitioned
