Description

The MAX72038B is a next-generation enhanced 38-PHY, serial-attached SCSI-2 (SAS-2)-compatible expander that operates at 1.5Gbps, 3.0Gbps, and 6.0Gbps (on a PHY-by-PHY basis). This device is used for server and enclosure applications for midrange- and enterprise-storage systems requiring active SAS port expansion.

This device offers an evolutionary upgrade path for systems that currently employ parallel SCSI technology and rely heavily on SCSI-centric software or management solutions. By combining industry-leading I/O, embedded enclosure functions, and a high-performance internal switching architecture, this device provides all the features needed to design, develop, and deploy high-performance SAS storage solutions.
