SMART Modular Technologies Flash Memory Drives Feature SEU Mitigation For Remote Applications
KUALA LUMPUR, Sept 19 (Bernama) -- SMART Modular Technologies Inc (SMART), a division of SGH announced a proprietary technology to mitigate the adverse impact of single event upsets (SEUs) in high-reliability flash-memory based systems.
SMART Modular’s MP3000 NVMe solid-state drive (SSD) products with SEU mitigation reduce annual failure rates from as high as 17.5k/ million units (Mu) to less than 10/Mu and can save hundreds of thousands of dollars in potential service costs by helping to ensure hundreds of hours of uninterrupted uptime, especially important for tough-to-repair remote deployments.
“In networking and telecom applications in remote and hard-to-service locations, SEU mitigation and the ability to recover from soft errors can make the difference for systems that require 24/7 uptime,” said its vice president of specialty memory, Satya Iyer in a statement.
SEUs are an inadvertent change in “bit status” that occurs in digital systems when high-energy neutrons, or alpha particles, randomly strike and cause bits in memory, logic components to literally flip their state.
These high-energy particles can originate from terrestrial or extraterrestrial sources such as cosmic rays. SEUs can lead to abnormal operation of digital systems or total system failure.
Addressing these errors or upsets within the SSD enable recovery without the need for a full system reboot which is critical in terms of maintaining reliable operations and uninterrupted runtimes.
The SEU mitigation technology is superior to other solutions that simply rely on error correction code (ECC) for the internal static random-access memory (SRAM). By having the ability to gracefully reboot itself without a host system reboot, the SSD also handles possible flipped bits in other components within the SSD which might account for an additional 10 per cent of failures.
Designed for applications that require maximum uptime, these boot drives with SEU mitigation come in storage capacity ranges from 60 gigabytes (GB) to 1.92 terabytes (TB), and are available in commercial and industrial temperature grades.
