Digital Payment: Come for the Flash Management, Stay for the Reliability

We recently had the opportunity to work with Digital Payment to solve a NAND flash corruption issue by using the validation tools that come standard in FlashFX Pro. You’ve probably seen their shiny parking meters around town, including many remote locations that have no permanent power and no easy access to service. That’s why when Digital Payment learned of the reliability benefits of Reliance, they saw an opportunity to improve up-time and lower service costs. Reliability is just one of many reasons their parking meters are popular with parking lot owners and municipalities looking for dependable, user-friendly machines. Be sure to check out the full case study for more information about Digital Payment’s experience with FlashFX Pro and Reliance.

Datalight Simplifies Reliable Data Storage for Linux-based Devices

Bothell, WA, – March 18, 2010 – Datalight announces support for Linux kernel versions up to 2.6.29 with new versions of FlashFX Tera, the file-system independent flash memory driver and Reliance Nitro, the highly-reliable, high-performance file system. FlashFX Tera version 1.2 offers out-of-the-box support for over 300 different flash memory parts from all the leading suppliers, expanding the choice for OEMs using flash memory. Linux is finding its way into more devices such as smart phones, automotive infotainment, and industrial equipment which require both responsiveness and 100% data reliability, by adding Reliance Nitro 1.2, OEMs can ensure rock-solid reliability of their systems without paying a performance penalty.

“Datalight continues to raise the standard in delivering advanced file system features for MontaVista Linux,” said Dean Misenhimer, Director of Marketing at MontaVista Software. “Our partnership provides our customers the option of a pre-integrated professional flash file system solution to speed their development of flash-based devices. This ultimately leads to faster time to market with superior performance and reliability.”

FlashFX Tera supports the full range of flash technologies including NAND, NOR, and MLC NAND flash in a single driver. Its patented wear-leveling and bad block management extend the useful life of devices using flash. While FlashFX Tera can be used with virtually any file system, pairing it with Reliance Nitro provides an optimized data storage software stack to simplify system development.

Reliance Nitro version 1.2 also adds support for extended file attributes. Most commonly used to designate file permissions, extended attributes are important to customers using special Linux distributions like SMACK. As data quantity and complexity in devices grows, extended file attributes can also be used for storing additional metadata (data about the data), such as digital rights information, GPS location or any information that makes finding and using the data easier. The ability of Reliance Nitro to serve as the root file system for Linux can simplify the data storage stack for these devices by allowing them to operate with a single file system.

“With the growth in adoption of Linux for data-intensive embedded devices, OEMs need a flash file system that better supports their reliability and performance requirements.” said Roy Sherrill, Datalight CEO. “By migrating our flagship products to Linux we’re filling that gap in the market with a robust, commercial-grade solution backed by our reputation for responsive, high-quality support.”

Reliability on Windows CE 6.0

Watch Rob Hart demonstrating the Datalight flash file system on the Beagle Board with Windows CE 6.0

I HEART Reliance Nitro

With the release of our new file system this week, Reliance Nitro, we asked our Account Managers what they liked most about our new product. Their answers of course included reliability and high performance. Wes Johns and Phillip Allison were so excited they decided to make a video…  watch the youtube video

Reliance Nitro Demo Video

We’re totally psyched about Reliance Nitro, our newest file system (yes, we’re file geeks), and we’re always on the lookout for opportunities to show off the performance and reliability attributes it adds to Windows Mobile and Windows CE. When we discovered the relatively-new Beagle Board, it occurred to us that a small, low-cost platform might be just the thing to demonstrate Nitro’s amazing benefits. As you’ve probably heard, the Beagle is making waves with its low cost (around $150) and diminutive size. It uses an OMAP 3530 processor and 256MB of NAND. Though they are most commonly used with Linux, we lucked out in having a partner (MPC Data) who has already developed a Windows CE BSP for it. After a few phone calls, the wizards at MPC Data were able to develop a slick video playback demo app, and presto, the Reliance Nitro Beagle Demo was born! Amateur videographers that we are (ok, REALLY amateur), we recently videotaped John Burnham, who has been working on this project on the Datalight side (and who is a really good sport, btw) showing what happens when power is interrupted during a file write and the extra reliability factor of Reliance Nitro on Windows CE.

Durability: The Next Killer App

Sea Change Hits Consumer Electronics as Customers Demand Long-term Value

For the first time in more than a decade, people are saving again. In 2007 and years prior, the savings rate hovered around zero as we maxed our credit cards and lines of credit, driving the savings rate into the red and giving the world’s manufacturing base an almost unbelievable boom. In January 2009 though, something unexpected happened; the US savings rate suddenly moved above 5%, the highest in decades. As news of our cloudy economic picture has emerged, consumer behavior is shifting away from status-seeking luxury purchases toward more value-based buying patterns, forcing manufacturers around the world to take notice. And after decades of excess, the shift to thrift is looking like a lasting trend.

But what does this mean for Embedded? As consumers focus on needs over wants, they will increasingly seek out products that are proven durable and reliable.

This will have broad implications for manufacturers of everything from cars to clothing, refrigerators to embedded devices. Today’s consumers are choosing efficiency, durability and value over gee-whiz gadgetry. Consumer mobile OEMs too must focus on delivering value and fewer, more targeted features. Rather than packing devices full of a laundry list of apps and expensive hardware, this means streamlined offerings and more segmented products, while making sure the consumer doesn’t feel like they’re missing out. Motorola’s new EM330 is a prime example of this kind of pared-down, demographic-specific approach. The phone, called the MOTOROKR STAR is marketed specifically toward music lovers, offering a basic clamshell with music recognition software and download-on-the-go at a price point in the sub-$200 range.

As OEMs scramble to add value and enhance their reputations for durability and reliability, Datalight responds with products that support those goals. The combination of flexible flash management that lowers bill of material costs, wear-leveling algorithms extend flash life by several times, and the rock-solid reliability of our file system become essential components of a strategy to provide value to customers.

Many have remarked that markets are driven by a combination of fear and greed. Though the pendulum has recently taken a dramatic –and we believe temporary– move in the direction of fear, ultimately we know a move away from excess is good for all of us and good for the world we live in. Here’s hoping the trend toward value and quality is a long-lasting one.

Making Lemonade in 2009

OEMs Position Themselves for the Economic Turnaround

 

As everyone’s mother used to say, “When life hands you lemons…” And at this particular time in embedded technology and elsewhere, it seems there is no shortage of them.  In just the last three weeks, we’ve heard about Nortel filing for bankruptcy, Motorola planning to cut 7,000 jobs, and Sony Ericsson’s dramatic profitability swing from $1.48 billion in 2007 to negative $96 million in 2008. And yet, one thing we know about recessions is that they inevitably end in expansion. The only question is when. With the fresh winds of optimism blowing in from Washington this week, now is as good a time as any to start planning your strategy for survival followed by world domination.

Indeed, if there is a silver lining to our current situation, it has to be the unprecedented opportunities for well-positioned, forward thinking companies to dominate their markets. Clearly, this takes grit, an eye on keeping costs down, and a truly differentiated product strategy. It’s more important now than ever before for OEMs to focus on their core competencies, keep bill of materials costs low and work with vendors who have experience weathering economic storms and possess the fortitude to survive tough times.

Datalight was born in 1983 during one of the worst recessions in the post-war era, and we remember well the challenges of the early 90’s and the aftermath of 9/11/01. While many of our competitors are pulling resources from flash file system development, we are moving ahead with a full schedule of product releases and innovation for 2009. While at CES this year, we discovered one of our competitors is pulling out of the flash file system business altogether. I won’t bore you with a long-winded sales pitch, because chances are if you’re reading this newsletter you already know Datalight can help you build better products with lower development costs and give you the ability to choose between the least expensive of over 300 NAND and NOR flash parts.

Like our new president, we are cautiously optimistic about the coming year. As President Obama said so well, this economy is going to take hard work and a little time to turn around. One thing we know for sure though, is that the turnaround is coming. Companies that design products their customers need and want, continue to invest in technology and communication, and prepare themselves to capitalize on a business environment with fewer competitors will do extremely well in the coming years.

Why Raw NAND Flash with Hardware-based ECC is the Way to Go

5 Reasons for Ditching Managed NAND
Everyone knows that NAND has challenges: from factory bad blocks and spontaneous bit failures to endurance limits, etc. That’s why a few years ago managed NAND (NAND flash plus an integrated controller) seemed to be the answer, offering the density of raw NAND, while mitigating many of its inherent limitations. What many device manufacturers may not realize is that the management hardware comes with significant costs, both in terms of dollars per part as well as design limitations. In the world of tradeoffs in which every system designer lives, there are solid technical reasons to consider using raw NAND and leaving the management to software instead. While there are clear commercial advantages for Datalight (as a provider of vendor-neutral software-based flash management) to advocate this approach, we also believe that there are strong technical reasons that flash silicon vendors would do well to embed ECC capabilities into their NAND flash devices rather than relying on ‘total hardware’ solutions such as eMMC or other complex and costly controllers. Beyond the benefits outline below, this approach would allow the flash manufacturers the ability to continue to differentiate their products from others in the industry.

1.    Cost
The cost of managed NAND parts is coming down, but the stuff still sells at a premium over its raw NAND brethren. 

2.    Flash Optimization
There are many new features of NAND available to us today.  Performance features such as cached reads, multi-plane operations, concurrency, and others are becoming invaluable to keep performance at the ever-increasing demands of portable media. The Open NAND Flash Interface (ONFI) has defined a standard method to query the capabilities and characteristics of NAND flash which can be put to use by both software and hardware systems. A software media manager offers the flexibility to take advantage of the most current flash memory features and put them to use efficiently, or to avoid certain features that may be unproven or problematic. A software solution will allow a developer to take full advantage of the media’s characteristics and features unburdened by the indirection or inability for the hardware to expose them.

3.    Visibility/Flexibility
Software (in general) is easily inspected and validated. Features such as wear-leveling move data around the flash device to optimize its life expectancy. Without the ability to inspect source code, a managed NAND solution makes it difficult to validate wear-leveling operation and/or characterize its effect on performance and reliability.  Hardware implementations are often generalized to suit a majority of use cases, while a software solution is easily tailored to the specific use case during development.

4.    Performance
Speaking of use cases, there are many system features that are not available to hardware that may make a generalized hardware solution less advantageous to a specific use case.  For example, system idle time can be used to improve the media performance by scheduling background cache operations and compaction to occur then.  Coordination between the file system and flash media manager can further optimize operations by freeing space when it will no longer be needed and having the media manager code cache certain regions of the flash where meta data might be held. Migrating flash management features to hardware removes this ability to coordinate with other components of the software stack, such as file systems.

5.    Reliability
Lest you think we believe that everything is better left to software, consider error detection and correction (EDC). Error rates are increasing substantially as flash manufacturers push the limits of physics.  Errors can be introduced externally by heat or other radiation, during writes or reads of data, and even to data that was successfully written at a different time. Historically SLC NAND flash required only a single bit error detection and correction (a hamming code is usually sufficient), while MLC parts require minimally four bit EDC.  As the die sizes continue to shrink, error rates will continue to increase, even for SLC flash. 
Calculating the codes to detect and correct such errors is getting increasingly complex and solving such a solution in software for higher-bit EDCs (above 4-bit) is time consuming and often unacceptably slow.  Hardware ECC is a necessary requirement for systems with high EDC requirements and where performance is a concern.

Many of the processors on the market today are incorporating EDC in their NAND controllers. Choosing one of these processors (e.g. TI OMAP 35xx) in combination with raw NAND flash and software management can give you the high-performance EDC to handle next generation flash while maintaining the design flexibility that a software manager provides.

Flash manufacturers have much to gain by adding ECC code into their NAND flash parts.  They know better than anyone what kind of ECC is necessary for a specific part and by adding just that one piece of hardware to their offerings, rather than the jack of all trades, master of none approach of complete flash management, they will better serve the markets. 

In short, features should reside where they can be handled most efficiently; ECCs belong in hardware, other flash management functions belong in software.  While managed NAND certainly has its place and its appeal in the market, we believe the best combination of value, performance and flexibility lies in using a combination of raw NAND and hardware with built-in ECC capabilities.
