As you can see on the product overview page, the SASWT4I leverages the LSI SAS1064E ASIC’s advanced LSI Fusion-MPT* architecture to provide entry-level hardware RAID. It utilizes the embedded CPU in the LSI SAS1064E ASIC to perform integrated RAID 0, 1, and 1E/10E operations. It's "entry-level" because it doesn't have RAID 5 or 6 support.
As for the RAID features:
Intel® Embedded Server RAID Technology: This is the software RAID technology
Intel® Integrated Server RAID: RAID solutions designed specially for Intel® server boards and systems. Built onboard, or RAID module with a special connector.
