Designed for connecting multiple targets and hosts, and featuring a small footprint, the SAS3x28R expander provides high performance expansion for the most demanding storage applications. 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-capcity and other storage applications. Optimized for server backplanes with limited space, this 28-port expander’s scalability, fault tolerance, and software support will make your storage applications perform like never before. The 3x28R 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 28 PHY edge expansion
  • Provide high device throughput with SAS and SATA support up to 12Gb/s, including wide port support
  • Leverage DataBolt technology to aggregate bandwidth from lower-speed drives for higher total performance
  • Ensure ample enclosure bandwidth through 2MB of integrated RAM and an ARM Cortex-R4 300 MHz processor
