Fortunately, the pronouncements of various storage experts about where all-flash storage will be in five years are far less gloomy. There is no doubt that all-flash is receiving market buy-in. So much so, that hybrid array sales are faltering and arrays made solely with hard disk drives (HDDs) are all but disappearing.
Gartner analyst Valdis Filks believes that solid-state arrays (SSAs) will improve in performance by a factor of 10, and double in density and cost-effectiveness within the next year. This is destined to change the dynamics of the storage market.
And from there, he sees many years of further expansion. Further, price erosion will probably reach a level to allow the complete substitution of SAS hard disks, reducing the usage of hybrid systems to usage areas that focus on the lowest costs per capacity and which do not have high-performance requirements.
SSAs are emerging as the general preference to hybrid arrays and as a clear replacement for aging disk arrays. Vendors are innovating with various form factors and technologies such as PCIe, NMVe and 3D XPoint. NVMe is a much-needed update to data transport mechanisms created in an era when Internet users were happy with 28k dial-up connections, This brings the communication channels around storage closer to the velocity of modern processors and flash architectures. NVMe also excites Jeff Boudreau, president, Dell EMC Storage Division.
He notes that although we are still in the early days of real NVMe usage in storage, it will become the industry standard in five years. Storage class memory (SCM) is a general term that may include specific vendor offerings such as 3D XPoint, ZSSD and others. It is also referenced sometimes as persistent memory (PMEM).
This memory technology promises to be 10 times denser and up to 1000 times faster than conventional flash. Jeff Baxter, chief evangelist for ONTAP at NetApp, agrees that the new possibilities offered by SCM and NVMe are disrupting the market and fueling innovation. NetApp has been developing NVMe-over-Fabrics technology over existing 32 GB FC SAN infrastructure from Brocade directly to NetApp AFF all-flash arrays running the NetApp ONTAP data management system.
It has also introduced SCM technology as a cache directly within an AFF storage controller, providing three times the IOPS with the same release of ONTAP, same controller and same workload.
These technological breakthroughs are the news of today. But in a few years, they will enter the mainstream. Users can expect to pay more for products containing SCM and other technologies for a while. Eventually, however, they will become the norm. These will be based on server designs with intelligent storage software on top, and less on dedicated storage controller design. When Rob Commins, vice president of marketing at Tegile looks into the crystal ball, he sees one large shared memory pool as opposed to a shared storage pool.
Eric Herzog, vice president of worldwide storage channels, IBM, concurs with other experts that we can expect NVMe and 3D XPoint to become increasingly more prevalent. He also called attention to recent discussions and presentations centered around RRAM as yet another wave of high performance, non-volatile storage media.
At the same time, he foresees flash moving down the food chain.
