Microsemi Corp., a wholly owned subsidiary of Microchip Technology Inc., has introduced what it claims is the first 24G SAS expanders for server and data center storage.
The expanders doubles the bandwidth of the storage interconnect and enables the full bandwidth of the PCIe Gen 4 to be utilized by the storage interconnect. The SXP 24G family 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 efficient aggregation for lower speed SATA and SAS hard disk drives and solid state drives, Microsemi said.
Seagate, Teledyne and MiTAC Computing Technology Corp. are already collaborating with Microsemi to enable the next generation of SSD and HDDs for servers and data centers.
The SXP24G expander family features variants ranging from 28 ports to 100 ports per device, DCM provides full utilization of 24G SAS bandwidth uplinks when aggregating 24G SAS, SAS-3, SAS-2 or SATA drives and firmware development framework that is backwards-compatible with existing SXP products
