MLC inside financial servers - new interview with Fusion-io's CEO

Editor:- December 7, 2010 - Fusion-io today announced that it has been working closely with Credit Suisse to integrate ioMemory SSDs with its Advanced Execution Services trading platform to improve its data access performance, maximizing the effectiveness of its low latency trading platform architectures.

Editor's comments:- trading banks using SSDs isn't new. So my initial inclination was to ignore this news story. But I'm glad I didn't - because I learned a lot when I spoke to Fusion-io's CEO David Flynn yesterday. Click on this link to see the interview.

Watts that DRAM doing to the power budget?

Editor:- December 7, 2010 - Rambus said it will unveil a new power modeling tool designed to understand and predict energy consumption in current and future DRAM device today at the MICRO-43 conference in Atlanta, GA.

The paper will later be posted on its online library.

Flash Cache Realities

Editor:- December 4, 2010 - Mike Workman, CEO of Pillar Data Systems recently published a blog - Cache Works – Sometimes.

In it he demonstrates why one of the failures of reality versus expectation in enterprise SSD acceleration is the "average flash cache performance" beloved by marketers. It's the peaks which are the memorable parts of the apps speedup experience.

CWCEC launches new rugged XMC/PMC SATA SSD

Editor:- December 3, 2010 - Curtiss-Wright launched the XMC-552 - a rugged 256GB XMC/PMC form factor SATA SSD with 200MB/s throughput, fast purge (in 4 seconds), bad block blocking and 128-bit AES encryption - for defense and aerospace applications.

will Micron's enhanced flash memory really eliminate error concerns?

Editor:- December 3, 2010 - Micron recently announced availability of enhanced 16GB to 64GB 25nm MLC flash memory chips with integrated error management - which the company says - removes the burden of ECC from the host and simplifies the use of flash in enterpise apps.

"The pace of NAND scaling is largely responsible for the incredible growth and success the industry has seen to date, and for helping to create new flash-based storage solutions," said Glen Hawk, VP of Micron's NAND Solutions Group. "While the advantages in NAND scaling are evident, so are the challenges with the technology becoming increasingly more difficult to manage. Micron's ClearNAND products remove this management burden for our customers and extend the life of this all-important technology."

Editor's comments:- as discussed in my recent article - bad block management in flash SSDs good blocks and less good blocks have always coexisted in flash memory. But as device geometries shrink (to increase capacity and speed) the margin of error between usable and non usable cells has shrunk too. In practical terms this means that the raw media quaility of new flash chips has declined in the past decade from under 1% defects, then 2%, 5% and I've seen projections as high as 10% for emerging MLC.

Managing these defects (which in theory are isolated and can be quarantined by vrtual address management techniques) is just one of the many data integrity challenges which SSD controller designers have to work with.

What is not generally appreciated is that it takes a lot of work and experience with the raw flash to create a model which you think represents how these bad bits will be distributed inside the chip population over time. The ECC designer's job is to create a correction model which gives the best data outcomes - given the raw material with which they have to work. Different designers may choose different strategies based on their intellectual understanding of the problem, patent portfolio, the market the SSD is designed for and other constraints.

If you could clone a bunch of flash chips and place them in 3 different SSD designs - the lifetime of those 3 SSDs would vary significantly - even running the same application and identical data. The difference would be due to how well the controller designers matched their management techniques to the decaying processes in the flash array.

By burying some of the ECC stuff inside the flash chip - Micron makes it easier for SSD designers to create an SSD which looks good when it is new. But it also introduces another risk factor - because if Micron get their models wrong - then many SSD designs may fail much earlier than predicted. That's always been true in the past too. In 5 years time we'll know better which designers got it right and which didn't.

In the distant past I used to design measuring instruments which pushed technology boundaries - and an important part of making them work was creating and testing error budget models - over time. Then in the process control world as now in SSDs - physics and chemistry are the realities which can rudely interrupt all your carefully contrived plans. Sometimes you're lucky it happens in the lab, or the test sites, but when there's a disagreement between the concept and the real world - reality always wins - reality is not a compliant servant and doesn't always fit snugly within the urgency of marketing plans.

2011 will be Year of Reality Checks for SSD Makers

Editor:- December 2, 2010 - Now's a good time to catch on your SSD reading - and time for me to predict what I think will be the main theme of the SSD market in 2011.

It's become a tradition in recent years as you can see if you trawl through my article which charts the 35 year rise of the SSD market.

The movie What Women Want has a funny scene where Mel Gibson is putting on panty hose. That could be a metaphor for product marketers in the SSD market too.

So I think 2011 is going to be the Year of Reality Checks for SSD makers.

Good for some (who discover that their markets are much bigger than analysts predicted) and bad for others (who discover that no one really cares if they exist or how their SSD IOPS compares with a hard drive).

new article - SSD Data Recovery Concepts and Technologies

Editor:- December 1, 2010 - today published a new article - Introduction to SSD Data Recovery Concepts and Technologies - written by Jeremy Brock, President, A+ Perfect Computers.

It's hard enough understanding the design of any single SSD. And there are so many different designs in the market.

If you've ever wondered what it looks like at the other end of the SSD supply chain - when a user has a damaged SSD which contains priceless data with no usable backup - this article - written by one of a rare new breed of SSD recovery experts will give you some idea. I've waited more than 3 years to find someone to write an article on this subject for you. And now it's only a click away - read the article

CERN chooses routers for teen petabyte era

Editor:- December 1, 2010 - Brocade (a SAN switch/router maker) today announced that CERN has selected its routers to work in a data environment that exceeds 15 petabytes per year.

Editor's comments:- there's a list of historic petabyte milestones in my article - SSDs - reaching for the petabyte .

what's inside the SSD? - readers want to know more

Editor:- December 1, 2010 - today listed the top 20 SSD articles (viewed by readers in November) on the market research page.

Pageviews of the classic SSD endurance article grew 48% year on year - making it the #1 most popular article for the 1st time - and dislodging the previous encumbant SSD Buyers Guide. The latter article has been shortened to make it more readable. For readers who still want to see a full 12 month timeline of noteworthy news stories in the SSD market this year the best starting place is here.

Reader interest in the nuances of technologies inside SSDs is indicated by the upward creep of the SSD controller page in this list - and the sustained strong interest in MLC, SLC and RAM memory issues and how they affect SSD performance, price and reliability. ...see the top 20 SSD articles
