24G SAS expanders for server, networked storage allows use of full PCIe Gen 4 bandwidth

Microsemi Corporation announced its new SXP 24G SAS expanders, the industry’s first 24G SAS (SAS-4) devices for server and networked storage. 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. This new family of devices is specifically designed to meet the demanding SAS storage infrastructure requirements by providing reliable, high performance, low power connectivity to both SAS and SATA HDDs and SSDs within the storage subsystem.

“SAS storage infrastructure continues to be a workhorse for data centers and we are extremely excited to further evolve our highly successful SXP SAS expander franchise this year by sampling the SXP 24G series of products,” said Andrew Dieckmann, vice president of marketing and applications engineering for Microsemi’s Data Center Solutions business unit. “In addition to being the first SAS expander products in the industry to support the new 24G SAS standard, the SXP 24G products will provide a significant power reduction, and include a wide range of port densities for a large variety of storage architectures while introducing Dynamic Channel Multiplexing (DCM) to enable high efficiency aggregation for lower speed SATA and SAS HDDs and SSDs.”

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

SXP 24G series solution highlights:

• Multiple device variants ranging from 28 ports to 100 ports per device
• Innovative Dynamic Channel Multiplexing (DCM) provides full utilization of 24G SAS bandwidth uplinks when aggregating 24G SAS, SAS-3, SAS-2 or SATA drives
• Significant power reduction compared to prior generations
• Firmware development framework backwards-compatible with existing SXP products

The SmartROC 3200 and SmartIOC 2200 are part of a full end-to-end solution of storage infrastructure and endpoint solutions for PCIe Gen 4 and 24G SAS.

SXP 24G SAS expanders will sample to select customers in 2018. For additional information, visit www.microsemi.com/smartstorage, www.microsemi.com/smartstorage/pcieg4 and www.microsemi.com/smartstorage/24gsas. For details on SXP 24G prototype availability, contact sales….@microsemi.com.
