24G SAS Expanders Address High Bandwidth Storage

Microsemi claims its SXP 24G family of devices are the industry's first 24G SAS (SAS-4) expanders for server and networked storage. Reportedly, 24G SAS doubles the bandwidth of the storage interconnect, which enables the full bandwidth of the PCIe Gen 4 to be utilized by the storage interconnect.


The SXP24G family includes an enhanced firmware development framework that enables users to preserve their firmware investment in prior generations of Microsemi's SAS expanders. The devices also feature Trusted Platform support, a unique level of platform security, which includes hardware root of trust that is aligned with initiatives like the Open Compute Security Project.
