Innovating Solid State Storage Solutions


  • Built-in features from our latest generations of Shannon Dirext-IOTM PCIe Flash(model G3s)include:
  • ◆ Ultra low-latency: 4KB random read as low as 68µs, random write at 10µs.
  • ◆ PCIe 2.0x4 interface with up to 1.6GB/s throughput, up to 390K 100% random IOPS.
  • ◆ 1x/1y nm NAND, HHHL card at 2.4TB.
  • ◆ Adaptive inter-chip flash RAID.
  • ◆ Power-cut safe
  • ◆ Up to Drive Write per Day for 3 years

Technical Summary

Shannon Direct-IOTM PCIe Flash presents host systems as a simple block-device, serving up a new memory tier that sits on the PCIe bus directly connected to the CPU.
This new memory tier is nearly as fast as DRAM with storage capacity on par with hard disks.

  • 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 (68µs Random Read/ 10µs 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. MTBF > 2 million hours)

  • 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 2.4TB (3.3TB raw) at a single half-height and half-length add-in card form-factor.

  • Compatibility

    Standard 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.
