The SAS35xR expanders are the second series of high performance 12 Gb/s SAS expanders that utilize a new, power-optimized design to deliver best in class power utilization and the latest enhancements in SAS technology. The 36-, 28- and 24-port expanders offer a smaller footprint and are equipped with an integrated ARM Cortex-R4 processor for system initialization, LED management, enclosure management, and topology management functions such as discovery. The SAS35xR expanders support end device SAS data transfer rates of 12, 6, 3 Gb/s, and SATA data transfer rates of 6 and 3 Gb/s. Representing the eighth generation of SAS expanders, the SAS35xR series adds a suite of enhanced power management features encompassing the ability to create vendor-unique SMP or SES commands. Firmware features include: SAS PHY Power Conditions, Partial and Slumber Power Management, Wake-In-Band and Enter/Exit Chip Wide-Low Power modes. The innovative and unique DataBolt bandwidth optimizer is carried forward from the prior generation expander and enhanced to provide robust 12 Gb/s performance while preserving prior investments in SAS and SATA devices. By buffering data received at 6 or 3 Gb/s rates and bursting to the host at 12 Gb/s speeds, the SAS35xR expanders with the DataBolt technology cost-effectively ease the transition to 12 Gb/s SAS technology and extend the longevity of the existing infrastructure. The SAS35xR expanders support scalability and the fault-tolerant path redundancy needed by today’s data centers, enterprise servers and storage subsystems. While connecting multiple targets and hosts in a switched SAS environment, the SAS35xR expanders improve system performance and reliability in feature-rich, power-efficient and industry-trusted offerings.
