We are so glad you enjoyed the article. Please note we have lots of other articles available regarding how to configure hardware (both computers and storage arrays) and operating systems to work best with SAS. You can find these articles on the SAS support web site at http://support.sas.com/kb/42/197.html

With regard to suggestions on RAID SSD vs single SSD vs RAID HDD, that choice is best left to your storage array vendor. From a SAS software perspective, just be sure to choose a configuration that gives you the I/O throughput required to meet user SLAs for SAS applications.
