Technical Summary

Shannon Direct-IO™ PCIe Flash

Shannon Direct-IOTM PCIe Flash is purposely designed for enterprise applications, remarkably accelerating mission-critical and performance-sensitive applications;

  • Native PCIe flash controller with
    ultra-scale parallelism

    Ultra-scale parallel multi-core processor flash controller, minimizes the intermediate processes and resource confliction, while achieves industry-leading low access latency (67µs Random Read/ 9µs Random Write)

  • Advanced reliability

    Advanced NAND signal processing and inter-chip flash RAID technology, guarding data with multi layers of protection; end-to-end data protection; always-on copy-on-write for data updates.

  • Power-loss data protection

    With no DRAM on board, or DRAM-less design, minimum amount of SRAM buffered-data are automatically flushed to flash media in case of sudden power-loss; guarantees data integrity without relying on battery or super-capacitor.

  • Flash life extension

    Adaptive signal processing technology for minimum flash wear; dynamic tracking and classification for host data (hot/cold), minimizes write amplification and extends system durability; endurance up to 5DWPD for 3 years.

  • Support the latest and next-gen flash

    Support 1x/1y nm NAND flash and upcoming 3D NAND; excellent scalability with capacity as high as 6.4TB (8.8TB raw) at a single full-height and half-length add-in card form-factor.

  • Compatibility

    Standard full-height half-length PCIe add-in form-factor;less than 25W peak power envelop, compatible with all standard rack server. Simple block-device accelerates mission-critical applications without any changes to existing software.
