SAS3x48 SAS Expander Ensure maximum performance and scalability for your most demanding storage requirements

Deliver the highest class of expander scalability and performance available with the SAS3x48 expander. Enabled for the latest 12Gb/s SAS and SATA specifications, the SAS3x48 supports T-10 zoning across 255 zones, port mirroring, spread spectrum clocking, and five 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.    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 Help ensure ample enclosure bandwidth through 2MB of integrated RAM and an ARM Cortex-R4 300 MHz processor
