In a word, yes. Find out why I think so in this blog...
There are clearly workloads that really do need NVMe performance today, but customers whose general-purpose enterprise storage platforms are coming up for technology refresh are also asking this. We've just completed a major primary research project into NVMe usage and released three documents based around it (a write-up on a series on in-depth interviews with customers already using NVMe, a worldwide NVMe survey (again, focused around those already using it), and a five-year revenue forecast…
This is a series of blogs that explore the use of NPS and address some of the criticisms that have been leveled against it over the years. NPS can be an effective tool in an enterprise storage vendor's arsenal, but how effectively a vendor designs and implements their "NPS program" will determine their success with it
More reaction to criticisms leveled against the use of NPS to evaluate customer experience…
Experience and NPS score rarely match. For an NPS score (or any tool, for that matter) to have predictive value it should consistently forecast some outcome. With NPS, the assumption is that a high number indicates lots of happy customers, and prospective customers looking at that might expect that if they purchase the product or service, they will also become happy customers. I don't know that I would…
This is a series of blogs that explore the use of NPS and address some of the criticisms that have been leveled against it over the years. NPS can be an effective tool in an enterprise storage vendor's arsenal, but how effectively a vendor designs and implements their "NPS program" will determine their success with it.
Over the last several years, there have been several startup enterprise storage vendors that have built a program around the Net Promoter Score (NPS) customer satisfaction metric that has generated a significantly differentiated customer experience. Early vendors to use this metric very successfully were Nimble Storage (now HPE), Nutanix, and Pure Storage. I looked at the NPS metric back in 2016 with a document entitled Why Enterprise Storage Managers Need to Understand the Net Promoter Score (I…
The IDC AFA MarketScape evaluated 10 vendors' enterprise storage platforms on their ability to meet requirements for dense mixed workload consolidation that includes at least some mission-critical applications. In this rapidly maturing market, there is still much to differentiate vendors. This document should provide food for thought for both customers and vendors alike.
In mid-December, IDC released the IDC MarketScape: Worldwide All-Flash Array 2017 Vendor Assessment (IDC, December 2017). Given the state of market maturity in the AFA space, it was necessary to narrowly focus assessment to arrays that were specifically sold for dense mixed workload consolidation that included at least some mission-critical applications. Many AFA vendors now have a broad portfolio of AFA platforms, targeting each at different types of workloads and customers. Other…
I had a chance to spend a few days at the Flash Memory Summit in Santa Clara this year, and this blog highlights some of the recent announcements in the AFA space from the show. NVMe was a major theme of the show, and we are seeing more enterprise storage vendors announce NVMe-based features, products and roadmaps.
At the Flash Memory Summit at the Santa Clara Convention Center this year, NVMe technology was a mainstream theme. IDC research indicates that 48% of enterprises already have NVMe deployed in some manner in their IT shops, but 99%+ of this is as local storage that was purchased after market and configured into PCIe slots on commodity x86 servers. While there were several rack scale flash vendors at the show (Apeiron Data Systems, E8 Storage, Excelero), the rack scale flash market is still an…
Some recent acquisitions in the SDS market - Nutanix bought PernixData and Red Hat bought Permabit - highlight a cautionary adage I often heard when working with venture capitalists in the past. When evaluating the future prospects of a funding opportunity, VCs want to understand whether a new business idea is a standalone product or is really just a feature that will quickly be integrated into a platform (presumably owned and shipped by someone else).
Software-defined storage (SDS) is a high growth area that is bringing some strong benefits – better agility, easier storage management, and reduced CAPEX – to those IT organizations that have the requisite skill to deploy it effectively. Some recent acquisitions in the SDS market – Nutanix bought PernixData and Red Hat bought Permabit – highlight a cautionary adage I often heard when working with venture capitalists in my past that is particularly relevant for software products. When evaluating…
Violin Memory, one of the early high flyers in the All Flash Array (AFA) space, filed for Chapter 11 bankruptcy in December 2016. This blog discusses some of the issues around their predicament, and takes a look at how the AFA market's use of custom flash modules (CFMs) (which Violin used in the Flash Storage Platform) has been impacted in enterprise-class arrays over the last couple of years.
The demise of Violin Memory, one of the early high flyers of the AFA market, has not been greatly exaggerated. The NYSE suspended trading in Violin Memory shares on October 28, 2016, and delisted its stock because it had not maintained an average global market capitalization of $15M over 30 consecutive trading days. From a revenue high of around $108M for their fiscal 2014, the company steadily shrank revenues in the wake of their September 2013 IPO. The company officially filed for Chapter 11…
As flash storage and network throughput evolve through the next several technology generations, a significant imbalance looms. As organizations decide which storage architecture they should go with - network storage or hyperconverged - it is important to understand how these two technologies are evolving in their own IT infrastructure.
Over the last several decades, processor performance improvements significantly outpaced storage performance improvements. All Flash Arrays (AFAs) which leverage flash media have helped to close this gap, which is one of the main drivers of their rapid penetration into mainstream datacenter infrastructure. Network performance is another key determinant in the actual performance that applications see, and existing network latencies and bandwidths have made flash performance accessible to them. …
Starting with the June 2016 Tracker release, we will be using an updated All Flash Array (AFA) taxonomy that is more inclusive. In a nutshell any arrays that ship from the factory in all-flash configurations and do NOT optionally support hard disk drives (HDDs) will be considered AFAs. There will be three classes (or types) of AFAs, defined based on pedigree, to help customers understand key differences between them.

Performance numbers released by vendors about their storage arrays are often based on "hero tests" that do not provide much help in communicating how a system will perform on real-world workloads. Should the vendor community strive for more realistic tests, or should customers come to better understand the limitations of existing tests? This blog explores these topics based on an informal lunch time round table discussion at IDC Directions West on March 2.
Enterprise storage marketers want to be able to apply some sort of performance characterization to their systems to help customers understand the capabilities of a storage array. At IDC Directions West in San Jose on March 2, I had an interesting lunch time conversation with a group of vendors on this topic.
Storage vendors have always used "hero tests" to generate the numbers they use to market their systems. A "hero test" is a test designed to produce the best performance number – for…
