The economical Intel RAID Controller SASWT4I offers exceptional entry-level hardware SAS/SATA RAID & non-RAID data off-load for server systems & workstations. This RAID controller allows for point-to-point connections with a SAS universal interconnect interface allowing for 1.5 & 3 Gb/s SATA hard disk drives along with logical SCSI compatibility for the extra reliability & manageability that SAS drives provide. The SASWT4I leverages the LSI SAS1064E ASICs advanced LSI Fusion-MPT architecture to provide entry-level hardware RAID. While other SAS controllers drive large RAID software stacks between the host CPU & controller, this RAID controller utilizes the embedded CPU in the LSI SAS1064E ASIC to perform integrated RAID 0, 1, & 1E/10E operations. By avoiding the PCI bus traffic & reducing RAID code overhead, the SASWT4I delivers world-class READ/WRITE operations.
