The votes have been counted, and the decision is in: 2014 is the year of the all-flash data center. The signs have been pointing in this direction for the past few years, and 2014 is the year when all the market factors have aligned to finally make it a reality. Storage Switzerland, an analyst firm, recently noted that an all-flash data center is now not only desirable on performance merits, but has finally emerged at an increasingly attractive price point. Due to this shift, major enterprises and service providers are now considering using all flash disks – also known as solid-state disks (SSDs) – in their data center architectures, an option that previously wasn’t even possible. Such a massive swing begs the question: Why flash, and why now? To fully understand, it is instructive to examine traditional “spinning disk” approaches to storage; including why spinning disks rose to prominence and the drawbacks that have cast flash in such a good light.
What the Future Brings
Disk storage used to be the next big thing, touted for its lower cost and higher efficiency than the tape storage it was replacing. When flash was introduced, spinning disks continued to march on as the standard server architecture of choice. Why? Despite flash’s substantially higher performance, it was just too expensive to consider as a full-fledged alternative to spinning disks. Furthermore, flash was smaller in capacity and unable to hold as much data per unit as spinning disks for the price...Read More
