Deliver the highest class of expander scalability and performance available with the LSI® LSI SAS3x40 expander. Enabled for the latest 12Gb/s SAS and SATA specifications, the LSI SAS3x40 supports T-10 zoning across 255 zones, port mirroring, spread spectrum clocking, and five I2C interfaces for enclosure management and debugging. The LSI DataBolt™ Bandwidth Optimizer aggregates bandwidth to provide 12Gb/s SAS performance using existing 6Gb/s or 3Gb/s devices, making it ideal for top-tier storage solutions.

  • Enable higher enclosure capacities through 40 PHY edge expansion
  • Provide high device throughput with SAS and SATA support up to 12Gb/s, including wide port support
  • Aggregate bandwidth from lower-speed drives for higher total performance with LSI DataBolt technology
  • Help ensure ample enclosure bandwidth through 2MB of integrated RAM and an ARM Cortex-R4 300 MHz processor
