LSI corporation is the first to implement new serial-attached SCSI (SAS) 12 Gb/s interface, geared for future generations of storage devices that can make use of that much bandwidth. For now, LSI proposes SAS expander chips that distribute that bandwidth among current-generation storage devices. The company displayed the world's first SATA 12 Gb/s add-on card, which uses PCI-Express 3.0 x8 interface to make sure there's enough system bus bandwidth. This card can connect to up to 44 SAS or SATA devices, and supports up to 2048 SAS addresses. It is backwards compatible with today's 6 Gb/s and 3 Gb/s devices.
