For those confused about the SAS/SATA thing this controller can do both
Adaptec decided to call this UNIFIED SERIAL ARCHITECTURE
-----------------------------------------------------------------
One Storage Architecture for SATA & SAS: Endless Possibilities

Choose an Adaptec Unified Serial™ controller to leverage cost-effective, high-capacity
Serial ATA (SATA) disk drives or high-performance Serial Attached SCSI (SAS) drives, or both, in a single storage system. Now, it’s possible to create solutions that are closely tailored to business needs today and also make upgrading or reallocating storage as simple as swapping disks.

For expanding a SCSI infrastructure, simply install an Adaptec Unified Serial controller in your server and as your data grows, take advantage of massive scalability up to 128 devices, or up to 60TB (using 500 GB drives).
