The LSI SAS2x28 Expander is designed for external storage subsystems . Fully backward compatible with LSI’s prior-generation expander, it delivers higher 6Gb/s SAS and SATA performance while preserving functionality.

  • Enable higher enclosure capacities through 28 PHY edge expansion
  • Ensure ample enclosure bandwidth through integrated RAM and an ARM926 processor
  • Customize unique firmware solutions with LSI software development kits (SDKs)
