Data Storage: NAND Flash in the Data Center: 10 Potential Pitfalls to Avoid
Perhaps the most consistent trend (for more than eight years now) in data storage, covering both the enterprise and consumer markets, is the continued development and improvement of solid-state disk NAND flash media. All the major storage and device companies offer solid-state drive (SSD) options for be servers, laptops and other devices. Tablet PCs have been using NAND flash all along, and their skyrocketing sales have been a huge validation of the media's market value. In the data center environment, however, there are some precautions and limitations in NAND flash that should be discussed and evaluated ahead of a major investment. This slide show discusses some of those topic areas. Our expert sources for this slide show are from Violin Memory: CTO and co-founder Jon Bennett and Vice President of Corporate Development Scott Metzger. Violin Memory, based in Sunnyvale, Calif., is a new-generation storage company that makes scalable, high-performance NAND flash enterprise arrays. We're staying away from specific product-related information in this slide show.
Many flash memory products solve for narrow application areas. Some database accelerators require a deeper understanding and tuning effort to implement for a very specific part of the application stack. Beware of "specialized" storage, the kind that says it is specially designed for a particular use case. If the system is optimized for whatever that use case looks like today, what happens tomorrow when the software or system vendor comes out with the next release and things change?
