Shannon Direct-IOTM PCIe Flash is purposely designed for enterprise applications, remarkably accelerating mission-critical and performance-sensitive applications;
3D-NAND technology further increases the capacity density and lowers the TCO for enterprise SSDs. Shannon Direct-IO® PCIe Flash employs the most advanced 3D-NAND flash and exploits a scalable architecture, providing a user capacity up to 12.8TB in a single SSD, an industry first-ever.
Shannon Direct-IO® PCIe Flash offers atomicity for any write operation of sizes less than 32KB. It can be enabled for database applications to significantly reduce latency and increase the QoS of SSD for mission critical database applications.
Key-Value store functionality is offered without relying on file systems, providing applications with direct access to NAND flash. Shannon Direct-IO® PCIe flash enables significant reduction in KV store access latency, which in-turn increases QoS for no-SQL applications, centric to today’s hyper scale data center infrastructure.
Shannon Direct-IO® PCIe Flash utilizes a DRAM-less architecture; minimum amount of SRAM buffered data are automatically and safely flushed to NAND in case of sudden power-loss, thus guaranteeing data integrity without relying on battery unit or super-capacitor.
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.
