Flash in the Data Center – Part 3 – What about PCIe Cards?

by JCRB on March 30, 2012

  Part 1 (Garbage Collection) and Part 2 (Commodity SSDs) What about PCIe cards? Another option is to pack as much flash as possible onto a PCIe card to sit in a high speed slot on a server.  Because of their much higher interface speeds, PCIe cards have much better performance than your typical commodity [...]


Stanford Talk on Flash Memory Design

by JCRB on March 15, 2012

Back to school day. Over at Stanford they have a speaker series that has been going on for the last few… decades, called the  Stanford University Department of Electrical Engineering Computer Systems Colloquium, known to many simply as EE380. The list of past speakers is as they say, long and distinguished, and includes such industry [...]


Flash in the Data Center? Part 1 – Roll your own and Garbage Collection

by JCRB on September 26, 2011

Flash is coming to the data center. Contrary to perception 18 months ago, now this seems to be accepted as ‘common knowledge.’ There is still much discussion around what that flash will look like and in what form it will be consumed. I plan to write a series of blogs describing the unique challenges involved [...]


Flash in the Data Center? Part 2 – Why not off the shelf SSDs?

by JCRB on May 17, 2012

In my last post I discussed a few of the technical aspects of flash that make it a unique storage media, particularly the complexity of garbage collection. Here we take a look at flash packaging and how that impacts architectural decisions. For this post I’ll focus on the question: “Should I use commodity SSDs?” and [...]
