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 will deliver 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 64k parallel queues, representing exponentially greater communication potential.
With 64k parallel 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.
Pure Storage will deliver all the benefits of NVMe – performance, density, and consolidation – with the same proven 99.9999% resiliency and Tier-1 data services that customers need for mainstream deployments.
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, can't be upgraded to NVMe. From this perspective, an investment today in one of these architectures is like making a future appointment with a forklift upgrade 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.
From the beginning, Pure Storage has sought to create products that capitalize on advances in storage and flash media. Thus, when FlashArray//M was designed a few years ago, Pure engineered compatibility for future technologies right into the product – including readiness for NVMe. In fact, the first //M ever shipped 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're guaranteeing every newly purchased FlashArray//M can be upgraded to NVMe through our Evergreen Storage program.* If we can’t make the upgrade work, we'll replace your array with a full NVMe array – for free.
