PCIe 4.0 RAID controller increases performance and maximizes design flexibility with Tri-Mode connectivity and NVMe devices


The MegaRAID 9500 series is the industry’s first PCIe Gen 4.0 RAID adapter family, offering PCIe Gen 4.0 host and storage interfaces. The MegaRAID 9560-16i adapter, based on the SAS3916 high-port count PCIe 4.0 x8 RAID-on-Chip (RoC), delivers twice the performance of previous generations.

The 9560-16i is compatible with existing PCIe SFF-8639 Module (U.2) backplanes, allowing users to boost performance for today’s ever increasing bandwidth environments. Coupled with two industry initiatives expanding the deployment of Tri-Mode SerDes technology, which enables the operation of NVMe, SAS or SATA devices in a single drive bay, the 9560-16i is instrumental in getting the most performance and flexibility out of U.3 backplanes:

- SFF-TA-10001 Specification (U.3), which defines a common bay type for SAS, SATA and NVMe
- Universal Backplane Management (UBM), which defines a common backplane control and management framework

With Tri-Mode SerDes technology, the adapter negotiates between speeds and protocols to seamlessly work with any of the three types of storage devices. Tri-Mode support provides a non-disruptive way to evolve existing data center infrastructure.
