SAS4x32 Expander Double the bandwidth over previous generations without compromising energy efficiency

Double the bandwidth over previous generations without compromising energy efficiency with the SAS4x32 expander, featuring the most SAS ports in Broadcom’s new SAS4xNN, pin-compatible SAS/SATA family of SAS-4 expanders. The 24G SAS interface supports 6G, 12G, 24G SAS and 6Gb/s SATA devices and data transfer rates. The SAS4x32 supports PHY and T-10 zoning across 255 zones, any-to-any port mirroring, spread spectrum clocking, and enhanced, multi-purpose GPIO architecture. The DataBolt2 bandwidth optimizer (up to 40 ports) enables bi-directional data buffering at the SAS-4 data rate to end devices operating at 6Gb/s or 12Gb/s and employs a new design to further lower latency and increase performance, even in mixed-controller topologies. The 4x32 expander is supported by an industry-leading SAS-4 Software Development Kit (SDK), a comprehensive, feature-rich tool designed to efficiently accommodate OEM-specific firmware implementations, or to be used as provided.

• Enable higher enclosure capacities through 32 any-to-any PHY edge expansion
• Double the effective bandwidth over prior 12Gb/s expanders without compromising energy efficiency or package size
• Provide high device throughput with SAS and SATA support, including wide port support
• Aggregate bandwidth from lower-speed drives for higher total performance with DataBolt2 technology
• Enhance the consistency of system performance in cascaded topologies (SPL-4 Fairness)
• Hardware Secure Boot maintains the designated root-of-trust throughout the life of the product
