SAS35x48 SAS Expander

Ensure maximum performance and scalability for your most demanding storage requirements

Currently Viewing:

Deliver the highest class of expander scalability and performance available. Enabled for the latest 12Gb/s SAS and SATA specifications, the SAS35x48 supports T-10 zoning across 255 zones, port mirroring, spread spectrum clocking, and twelve I2C interfaces for enclosure management and debugging. DataBolt bandwidth optimizer technology aggregates bandwidth to provide 12Gb/s SAS performance to the host when using 6Gb/s and 3Gb/s SATA end devices, making it ideal for high-capacity and other storage applications. The 35x48 expander is supported by an industry-leading Software Development Kit (SDK) and tool suite for easy integration, de-bug and troubleshooting.
 
  • Enable higher enclosure capacities through 48 PHY edge expansion
  • Provide high device throughput with SAS and SATA support up to 12Gb/s, including wide port support
  • Aggregated bandwidth provides higher total performance with DataBolt technology
  • Lowest power utilization expander and industry-leading SerDes for performance and robustness
