Device Overview

Summary

The SXP 12G 24-port SAS expander features SAS-3 T10 zoning, self-configuration, table-to-table routing, Ethernet port, and an integrated MIPS processor for SES and enclosure management support. All SXP expanders also feature a rich and robust customizable SDK for enclosure management and system level diagnostics and monitoring that offers our customers a clean migration path for their code between product generations.

For product comparison, please consider: PM8056, PM8055, PM8054, PM8044, PM8043
