SAS3x40 SAS Expander Achieve high performance and scalability for your most demanding storage systems
Deliver the highest class of expander scalability and performance available. Enabled for the latest 12Gb/s SAS and SATA specifications, the SAS3x40 supports T-10 zoning across 255 zones, port mirroring, spread spectrum clocking, and 12 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-capcity and other storage applications. The 3x40 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 40 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
Help ensure ample enclosure bandwidth through 2MB of integrated RAM and an ARM Cortex-R4 300 MHz processor
