The current generation of all-flash arrays offers enough performance to saturate the network connections between the arrays and application servers in the data center. In many scenarios, the key limiter to all-flash array performance is storage network bandwidth. Therefore, all-flash array vendors have been quick to adopt the latest advances in storage network connectivity.
The ratification in November 2018 of the NVMe/TCP standard officially opened the doors for NVMe/TCP to begin to find its way into corporate IT environments. Earlier this week I had the opportunity to listen in on a webinar that SNIA hosted which provided an update on NVMe/TCP’s latest developments and its implications for enterprise IT. Here are four key takeaways from that presentation and how these changes will impact corporate data center Ethernet network designs.
NVMe and other advances in non-volatile memory technology are generating a lot of buzz in the enterprise technology industry, and rightly so. As providers integrate these technologies into storage systems they are closing the gap between the dramatic advances in processing power and the performance of the storage systems that support them. The TrueNAS M-Series from iXsystems provides an excellent example of what can be achieved when these technologies are thoughtfully integrated into a storage system.
Storage vendors hype NVMe for good reason. It enables all-flash arrays (AFAs) to fully deliver on flash’s performance characteristics. Already NVMe serves as an interconnect between AFA controllers and their back end solid state drives (SSDs) to help these AFAs unlock more of the performance that flash offers. However, the real performance benefits that NVMe can deliver will be unlocked as a result of four key trends set to converge in the 2019/2020 time period. Combined, these will open the doors for many more companies to experience the full breadth of performance benefits that NVMe provides for a much wider swath of applications running in their environment.
When it comes to the mix of data protection challenges that exist within enterprises today, these companies would love to identify a single product that they can deploy to solve all their challenges. I hate to be the bearer of bad news, but that single product solution does not yet exist. That said, enterprises will find a steadily improving ecosystem of products that increasingly work well together to address this challenge with HPE being at the forefront of putting up a big tent that brings these products together and delivers them as a single solution.
DCIG’s latest Pocket Analyst Report examines the flagship all-flash arrays from HPE and NetApp. The report identifies many similarities between the HPE 3PAR StoreServ and NetApp AFF A-Series products, including the ability to deliver low latency storage with high levels of availability, and a relatively full set of data management features. DCIG’s Pocket Analyst Report also identifies six significant differences between the products. These differences include how each product provides deduplication and other data services, hybrid cloud integration, host-to-storage connectivity, scalability, and simplified management through predictive analytics and bundled or all-inclusive software licensing.
Dell EMC VMAX and HPE 3PAR StoreServ arrays can meet the storage requirements of most enterprises, yet differences remain. DCIG compares the current AFA configurations from Dell EMC and HPE in its latest DCIG Pocket Analyst Report. This report will help enterprises determine which product best fits with its business requirements. Features such as data center footprint, licensing simplicity, mainframe connectivity, performance resources, predictive analytics, raw storage density and effective storage density are key areas where these two products differentiate themselves.
Both Hitachi Vantara and NetApp refreshed their respective F-Series and A-Series lines of all-flash arrays (AFAs) in the first half of 2018. While some of these changes reinforced the respective strengths of each of their product lines, other changes provided some key insights into how these two vendors see the AFA market shaping up in the years to come. Features such as host-to-storage networking connectivity, predictive analytics, support for public clouds, and data protection and flash performance optimization are key areas where these two products differentiate themselves.
Mainstream enterprise storage vendors are embracing NVMe. HPE, NetApp, Pure Storage, Dell EMC, Kaminario and Tegile all offer all-NVMe arrays. According to these vendors, the products will soon support storage class memory as well. NVMe protocol access to flash memory SSDs is a big deal. Support for storage class memory may become an even bigger deal.

Almost any article published today related to enterprise data storage will talk about the benefits of flash memory. However, while many organizations now use flash in their enterprise, most are only now starting to use it at a scale where they use it to host more than a handful of their applications. As organizations look to deploy flash more broadly in their enterprises, here are six best practices to keep in mind as they do so.
Much has changed since DCIG published the DCIG 2017-18 All-Flash Array Buyer’s Guide just one year ago. The DCIG analyst team is in the final stages of preparing a fresh snapshot of the all-flash array (AFA) marketplace. As we reflected on the fresh all-flash array data and compared it to the data we collected just a year ago, we observed seven significant trends in the all-flash array marketplace that will influence buying decisions through 2019.
The exhibit halls at the annual National Association of Broadcasters (NAB) show in Las Vegas always contain eye-popping displays highlighting recent technological advances as well as what is coming down the path in the world of media and entertainment. But behind NAB’s glitz and glamour lurks a hard, cold reality; every word recorded, every picture taken, and every scene filmed must be stored somewhere, usually multiple times, and available at a moment’s notice. It is these halls at the NAB show that DCIG visited where it identified two start-ups with storage technologies poised to disrupt business as usual.
Enterprise storage startups are pushing the storage industry forward faster and in directions it may never have gone without them. It is because of these startups that flash memory is now the preferred place to store critical enterprise data. Startups also advanced the customer-friendly all-inclusive approach to software licensing, evergreen hardware refreshes, and pay-as-you-grow utility pricing. These startup-inspired changes delight customers, who are rewarding these startups with large follow-on purchases and Net Promoter Scores (NPS) previously unseen in this industry. Yet the greatest contribution startups may make to the enterprise storage industry is applying predictive analytics to storage.
Non-volatile Memory Express (NVMe) has captured the fancy of the enterprise storage world. Implementing NVMe on all-flash arrays or hyper-converged infrastructure appliances carries with it the promise that companies can leverage these solutions to achieve sub-millisecond response times, drive millions of IOPS, and deliver real-time application analytics and transaction processing. But differences persist between what NVMe promises for these solutions and what it can deliver. Here is a practical look at NVMe delivers on these solutions in early 2018.
Early in my IT career, a friend who owns a software company told me he had been informed by a peer that he wasn’t charging enough for his software. This peer advised him to adopt a “flinch-based” approach to pricing. He said my friend should start with a base licensing cost that meets margin requirements, and then keep adding on other costs until the prospective customer flinches. My friend found that approach offensive, and so do I.
The all-flash array market has settled down considerably in the last few years. While there are more all-flash arrays (90+ models) and vendors (20+) than ever before, the ways in which these models can be grouped and classified has also become easier. As DCIG looks forward to releasing a series of Buyer’s Guides covering all-flash arrays in the coming months, it can break these all-flash arrays into five (and soon to be six) general classifications based upon their respective architectures and use cases.
Simplicity is one of those terms that I love to hate. On one hand, people generally want the products that they buy to be “simple” to deploy and manage so they can “set them and forget them.” The problem that emerges when doing product evaluations, especially when evaluating all-flash arrays(AFAs), is determining what features contribute to making AFAs simple to deploy and manage. The good news is that over the last few years five key features have emerged that organizations can use to measure the simplicity of an AFA to select the right one for their environment.
Many organizations are using all-flash arrays in their data centers today. When asked about the benefits they have achieved, two benefits are almost always top of mind. The first benefit mentioned is the increase in application performance. Indeed, increased performance was the primary rationale for the purchase of the all-flash array. The second benefit came as an unexpected bonus; the decrease in time spent managing storage. As organizations consolidate many applications on each all-flash array; and are discovering that data tiering and quality of service features are important for preserving these benefits.
