In an increasingly digital world, demand is rising for high-throughput and high-capacity memory and storage solutions. For mission-critical applications like those in the aerospace, defence and surveillance industries, these solutions must demonstrate rock-solid data reliability, integrity, security and performance.
Solid state drive and DRAM manufacturer Innodisk offers an array of products that meet these demanding requirements, along with innovative feature sets like InnoRobust™ and InnoRec™, encompassing a range of technologies that provide reliable, stable and secure data storage. In addition to flash storage and dynamic memory solutions, Innodisk also offers flexible expansion modules including CANbus, LANcard and display extension cards.
Direct supply and design support is available by partnering with Astute Electronics, an electronics distributor specialised in franchised, high-reliability products and trusted by many of the world’s biggest defence companies.
1. Reliability in harsh environments and operating conditions
Rugged design is essential to reliable function in the tough operating conditions of aerospace and defence applications. Innodisk’s flash and DRAM modules with InnoRobust™ are compliant to MIL-STD-810. They operate over a wide temperature range that exceeds JEDEC standards, from -40° C to 85° C, and are tested to endure the expansion and contraction associated with cycling temperatures. Intelligent algorithms distribute workloads to minimise working temperatures and prevent overheating based on the output of an integrated thermal sensor. An innovative design that separates the SSD controller and flash memory with copper maximizes passive cooling.
Anti-sulfuration protection guards silver alloys in all DDR4 DRAM modules against corrosion when exposed to sulfur gases. In addition, conformal coatings protect modules against contaminants, moisture and acids to IPC-A-610 standards. Side fill with resin on three sides of the DRAM IC increases endurance against thermal and mechanical stresses. Galvanic isolation protects modules from surges up to 2.5 kV.
2. Data protection and integrity in all situations, including power failure
Preserving data in every scenario – including in the event of adverse conditions like power failure – is important in mission-critical applications. Innodisk’s iCell, iData Guard and iPower Guard™ technologies – part of the InnoRobust™ feature set – work together to deliver this capability. With iCell, additional capacitors are included on the SSD’s IC to provide 60 ms of power during power failures to store buffered data – 30 times longer than traditional SSDs. The iData Guard algorithm protects data by instructing the controller to stop accepting host commands and immediately complete the last operation upon detecting a voltage drop. iPower Guard™ defends against damaging power supply instabilities by creating a buffer zone to counter voltage fluctuations before startup and requires post-shutdown residual voltages near 0 V before a restart is allowed.
In applications involving national security, preventing sensitive data from being compromised is of paramount importance. Innodisk’s self-encrypting drives are fully protected by hardware-based, 256-bit AES encryption. They are also compliant with TCG Opal 2.0 for easy and secure storage management.
In addition, the InnoRobust™ feature set includes a suite of data erasure capabilities, known as Security Erase, to ensure that adversaries cannot access information even if they obtain the physical drive. Security Erase includes the following functions.
- Quick Erase deletes data in seconds.
- Destroy removes and renders all data and firmware unrecoverable.
- Physical Destroy fries the module’s memory cells with a high-voltage current to guarantee complete and irreversible destruction of data.
The emergency data erasure procedures comply with the following military standards: DoD 5220.22-M, USA-Army 380-19, USA-AF AFSSI 5020, NISPOMSUP Chap 8, Sect. 8-501, USA Navy NAVSO P-5239-26, NSA Manual 9-12, NSA Manual 130-2 and IRIG 106.
4. Optimum storage management for stable performance and data preservation
Maintaining stable read-write performance when recording video is crucial to ensure that frames are not lost in surveillance applications. Innodisk’s InnoRec™ feature set includes RecLine™ technology, which optimises disk management to deliver consistent write performance. Recording operations are assigned priority over garbage collection, trim and wear leveling tasks, which are efficiently allocated resources in the background. This ensures that every frame is recorded for pristine video quality. InnoRec™ also provides many of the same module integrity technologies included in the InnoRobust™ feature set, including iData Guard, iCell and Quick Erase, as well as overheat protection provided by an integral thermal sensor and defence against contaminants with optional conformal coating.
Data stored on solid-state flash memory is subject to finite lifetimes due to charge leakage from NAND cells, an effect that is amplified in high-temperature environments and for cells that have gone through many program-erase (P/E) cycles. Innodisk’s iRetention feature actively preserves data by refreshing it periodically. The algorithm intelligently erases and rewrites data block-by-block based on P/E cycle number and temperature. This ensures that data-retention time is significantly extended compared to conventional SSDs, even in challenging high-temperature conditions.
Aerospace, defenCe and surveillance applications require memory and storage solutions that are highly reliable, secure and stable in even the toughest operating conditions.
