Looking to improve system reliability? The LSI SASx28 Expander provides large storage environments the ability to connect multiple targets and initiators through a switched device for scalability and fault-tolerant path redundancy. It’s ideal for datacenter and storage subsystems leveraging 3Gb/s SAS and SATA drives.

  • Enable higher enclosure capacities through 28 PHY edge expansion
  • Provide high device throughput with SAS and SATA support up to 3Gb/s, including wide port support
  • Ensure ample enclosure bandwidth through integrated RAM and an ARM processor
  • Supports 1.5 Gbit/s SATA connections
