LSI Corp. has announced it is shipping samples of 6Gbit/s Serial Attached SCSI (SAS) expander ICs to major OEM customers. By providing OEMs with samples of its second-generation SAS expander IC products, LSI is laying the groundwork for complete 6Gbit/s SAS ecosystems, which the SCSI Trade Association estimates will be available in the second half of 2009.

The LSI SAS2x36 is a 36-port 6Gbit/s SAS expander with an integrated ARM processor for topology management functions such as discovery and enclosure services. It supports SAS and SATA data transfer rates of 1.5-, 3- and 6Gbit/s and incorporates enhanced features such as spread spectrum clocking for EMI reduction, T10-based zoning for network storage security applications, and SAS multiplexing to maximize bandwidth performance to legacy storage devices. The LSI SAS2x36 SAS expander provides storage environments with the ability to connect multiple hosts and targets through a switched device for scalability and with fault-tolerant path-redundancy to improve system reliability ideal for today's enterprise data centers.

The 6Gbit/s SAS will provide up to double the transfer rate of 3Gbit/s SAS solutions and offer greater scalability, while also providing new features including expander zoning, spread spectrum clocking and support for the T10 Protection Information Model for greater reliability, Decision Feedback Equalization for longer cables, and multiplexing. SAS-2 also provides backward compatibility with 3Gbit/s SAS technologies.
