FerriSSD® Supports Single Root-IO Virtualization

One Storage Directly Support Virtual I/Os to Multiple VFs

The SR-IOV architecture applies the concept of virtualization. Its architecture provides for the direct connection of multiple automotive modules to an SSD via PCIe channels. This provides the flexibility to run a VM on any supported hardware target and optimizes the usage of the available hardware resources.

The advantage of virtualized architecture is that data transfers no longer need to be routed via the hypervisor (virtual machine manager, or VMM), thus eliminating the delay caused by translating software code from PCIe format into hypervisor format and back again. This also reduces the burden on the CPU in which the hypervisor runs.

Now offered with built-in SR-IOV capability, a single FerriSSD® device from Silicon Motion in a virtualized architecture can support up to eight VMs, which are implemented in hardware on the embedded SSD controller, providing a direct, high-speed PCIe interface to each VM via a dedicated virtual function (VF) implemented in the SSD controller.

Cost saving – replacing multiple, lower performance, less robust storage devices with a single, high-performance SSD.
Low Latency – the SR-IOV capability provides for near-native QoS in a flexible virtualized architecture.
Reduced CPU utilization – thanks to the elimination of the hypervisor layer between virtual machines and an SR-IOV-enabled SSD.

FerriSSD®: End to End Data Path Protection to Guarantee Data Integrity

Silicon Motion's FerriSSDs incorporate full data error detection with recovery engines to provide enhanced data integrity throughout the entire Host-to-NAND-to-Host data path. The FerriSSD® data recovery algorithm can effectively detect any error in the SSD data path, including hardware (i.e. ASIC) errors, firmware errors and memory errors arising in SRAM, DRAM or NAND.

FerriSSD®: NANDXtend® ECC technology to Extend Operating Lifetime

Conventional SSDs employ standard BCH and RS ECC (error correction coding) engines to initiate first-level correction using NAND shift-read-retries. In addition to this first-level error correction, FerriSSDs also implement a highly efficient second-level correction scheme using an LDPC (low-density parity-check) code and an advanced RAID algorithm (a highly efficient redundant backup) to reduce potential dPPM at customer site while extending the service life of SSD.

IntelligentScan™ and DataRefresh™ to Enhance Data Retention in High Temperature Environment

Silicon Motion's proprietary IntelligentScan function will activate automatically to scan recharge, repair or retire the cell block (DataRefresh) according to the host behavior and working environment (eg. ambient temperature). As a result of the combination of IntelligentScan and DataRefresh, FerriSSD® can effective prolong its service life much beyond typical NAND specifications.
