Everywhere you turn, there's a speed-related analogy for solid-state: "It's a turbo booster for your IT ecosystem" and "Solid-state storage is the Ferrari of the storage world." This makes sense because solid-state storage technology provides an obvious performance benefit over spinning media technology, resulting in improved application response times and reduced latencies. But sometimes focusing on the obvious can cause us to miss the bigger picture. Reduced latencies are just one of solid-state's potential benefits, and overemphasizing this benefit may prevent some organizations from reaping larger rewards.
So why do so many miss the big picture? A cursory glance of the technology reveals the obvious: it's really fast and a little pricy when compared to spinning media. In my conversations with IT leaders, I often hear that they want solid-state technology … but for a lower dollar-per-gigabyte price. That's fine, but storage performance has never been purchased that way. For years, short stroking -- trying to squeak a few more I/Os out of each platter by throwing away capacity -- was the rage. If price per capacity didn't make sense for spinning media, why do organizations rely on it to compare performance-centric solutions today? It's easier to do it that way. However, price per capacity is the wrong way to evaluate emerging solid-state storage technology, and it causes many individuals to overlook much of the disruptive power of solid-state.
I often hear IT professionals say their solid-state is fast, but that their current storage performance is good enough. It's a common response, as storage admins usually size their storage deployment to meet the needs of their applications.
That's the challenge of focusing on storage performance alone. Some organizations don't realize that by eliminating the storage bottleneck, solid-state technology can enhance the performance of the entire ecosystem and reduce costs across the IT environment. Here are a few examples of how solid-state storage technology can provide benefits outside of the storage system:
Back within the storage system, reducing latencies may not be as important as providing predictability for more traditional IT applications. As application demands fluctuate or organizations add more workloads to the existing infrastructure, the extra performance headroom provided by solid-state(especially if the system offers quality of service capabilities), can ensure that increased organization demands won't impact existing application performance.
The key takeaway is that the performance provided by solid-state storage technology is not limited to the storage system. If you were waiting for the ROI to improve before making an investment in solid-state storage, you may want to check your math. The value may already be there.
