The next great advance in enterprise storage speed and consolidation is upon us, and it’s the shift to NVMe. A high-performance technology that’s already in laptops and phones, NVMe is faster and more parallel than SAS, and enables a significant increase in performance and density for those storage architectures that are ready for it.
Today’s fastest all-flash storage architectures are fundamentally limited by SAS-based serial connectivity, which is inevitably a bottleneck: no matter how many CPU cores you’ve got or how dense your flash, all data must move serially. NVMe, on the other hand, offers thousands of parallel queues, representing exponentially greater communication potential.
With thousands of queues, NVMe enables compute and storage to engage in massively parallel communication. NVMe’s huge throughput advantage over SAS is going to be required to take advantage of tomorrow’s advances in multi-core CPUs, super-dense SSDs, new memory technologies, and high-speed interconnects.
Storage architectures that aren’t prepared for NVMe – and there are many of them – will be left behind over the next few years. Legacy arrays and flash retrofits, for instance, probably can’t be upgraded to 100% NVMe. From this perspective, an investment today in one of these architectures is like making a future appointment with a forklift upgrade, a full storage re-purchase, and yet another data migration.
Industry analysts forecast that NVMe will become the leading interface protocol for flash by 2019. A critical mass of consumer devices has already shifted to NVMe, and the enterprise will not be far behind.
All the benefits of NVMe – performance, density, consolidation – are available today in FlashArray//X. And you get all the Tier-1 data services and proven 99.9999% availability that you need for mainstream deployments.
FlashArray//M is just a non-disruptive, Evergreen upgrade to the 100% NVMe power of //X. When //M was designed a few years ago, Pure engineered compatibility with future technologies right into the product – including readiness for NVMe. In fact, the very first //M already had dual-ported, hot-pluggable NVMe NV-RAM modules, an industry first at the time.
We’re so confident of our readiness for NVMe that we guarantee every newly purchased FlashArray//M can be upgraded to full NVMe through an Evergreen upgrade to FlashArray//X.* If we can’t make the upgrade work, we’ll replace your array with a full NVMe array – for free.
