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.
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.
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.
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.
Today organizations more so than ever are looking to move to software-defined data centers. Whether they adopt software-defined storage, networking, computing, servers, security, or all of them as part of this initiative, they are starting to conclude that a software-defined world trumps the existing hardware defined one. While I agree with this philosophy in principle, organizations need to carefully dip their toe into the software-defined waters and not dive head-first.
In early November DCIG finalized its research into all-flash arrays and, in the coming weeks and months, will be announcing its rankings in its various Buyer’s Guide Editions as well as in its new All-flash Array Product Ranking Bulletins. It as DCIG prepares to release its all-flash array rankings that we also find ourselves remarking just how quickly interest in HDD-based arrays has declined just this year alone. While we are not ready to declare HDDs dead by any stretch, finding any sparks that represent interest or innovation in hard disk drives (HDDs) is getting increasingly difficult.
In today’s enterprise data centers, when one thinks performance, one thinks flash. That’s great. But that thought process can lead organizations to think that “all-flash arrays” are the only option they have to get high levels of performance for their applications. That thinking is now so outdated. The latest server-based storage solution from Datrium illustrates how accelerating application performance just became insanely easy by simply clicking a button versus resorting to upgrading some hardware in their environment.
DCIG is pleased to announce the September 29 release of the DCIG 2015-16 All-Flash Array Buyer’s Guide that weights, scores and ranks more than 100 features of twenty-eight (28) all-flash arrays or array series from eighteen (18) enterprise storage providers.
Since the publication of the DCIG 2014-15 Flash Memory Storage Array Buyer’s Guide, the storage industry has embraced the term all-flash array. For that reason the forthcoming refresh of the buyer’s guide will be called the DCIG 2015-16 All-Flash Array Buyer’s Guide. More than terminology has changed over the last eighteen (18) months. The fresh data DCIG compiled shows that all-flash array vendors have substantially reduced the barriers to all-flash array adoption.
Almost any hybrid or all-flash storage array will accelerate performance for the applications it hosts. Yet many organizations need a storage array that scales beyond just accelerating the performance of a few hosts. They want a solution that both solves their immediate performance challenges and serves as a launch pad to using flash more broadly in their environment.
On March 17, 2015, the Storage Performance Council (SPC) updated its “Top Ten” list of SPC-2 results that includes performance metrics going back almost three (3) years to May 2012. Noteworthy in these updated results is that the three storage arrays ranked at the top are, in order, a high end mainframe-centric, monolithic storage array (the HP XP7, OEMed from Hitachi), an all-flash storage array (from startup Kaminario, the K2 box) and a hybrid storage array (Oracle ZFS Storage ZS4-4 Appliance). Making these performance results particularly interesting is that the hybrid storage array, the Oracle ZFS Storage ZS4-4 Appliance, can essentially go toe-to-toe from a performance perspective with both the million dollar HP XP7 and Kaminario K2 arrays and do so at approximately half of their cost.

At the beginning of 2014, I started the year with the theme: “it’s an exciting time to be part of the DCIG team“. This was due to the explosive growth we saw in website visits and popularity of our Buyer’s Guides. That hasn’t changed. DCIG Buyer’s Guides continue to grow in popularity, but what’s even more exciting is the diversity of our new products and services. This year’s theme is diversity: a range of different things. DCIG is expanding…again…in different directions. In the past year, we have added a number of offerings to our repertoire of products and services. In addition to producing our popular Buyer’s Guides and well known blogs, we now offer Competitive Research Services, Executive Interviews, Executive White papers, Lead Generation, Special Reports and Webinars. Even more unique, DCIG now offers an RFP/RFI Analysis Software Suite. This suite gives anyone (vendor, end-user or technology reseller) the ability to license the same software that DCIG uses internally to…

Dedicating a single flash-based storage array to improving the performance of a single application may be appropriate for siloed or small SAN environments. However this is NOT an architecture that enterprises want to leverage when hosting multiple applications in larger SAN environments, especially if the flash-based arrays has only a few or unproven data management services behind it. The new Oracle FS1 Series Flash Storage System addresses these concerns by providing enterprises both the levels of performance and the mature and robust data management services that they need to move flash-based arrays from the fringes of their SAN environments into their core.
A couple of weeks ago I attended the Flash Memory Summit in Santa Clara, CA, where I had the opportunity to talk to a number of providers, fellow analysts and developers in attendance about the topic of flash memory. The focus of many of these conversations was less about what flash means right now as its performance ramifications are already pretty well understood by the enterprise. Rather many are already looking ahead to take further advantage of flash’s particular idiosyncrasies and, in so doing, give us some good insight into what will be hot in flash in the years to come.
There is literally a divergence occurring right now in data storage solutions. On one hand, a number of storage providers seek to deliver highly differentiated storage solutions that work with a broad set of applications and operating systems. On the other, a few providers focus on delivering a storage solution that tightly integrates with one or more applications to deliver unparalleled levels of application performance and ease of management. The latest Oracle ZFS Storage Appliance ZS3 Series with its new OS8.2 provide the best of what both of these categories of storage systems currently have to offer to deliver a storage platform that truly stands apart.
The use of data reduction technologies such as compression and deduplication to reduce storage costs are nothing new. Tape drives have used compression for decades to increase backup data densities on tape while many modern deduplicating backup appliances use compression and deduplication to also reduce backup data stores. Even a select number of existing HDD-based storage arrays use data compression and deduplication to minimize data stores for large amounts of file data stored in archives or on networked attached file servers.
Toward the end of April Wikibon’s David Floyer posted an article on the topic of server SANs entitled “The Rise of Server SANs” which generated a fair amount of attention and was even the focus of a number of conversations that I had at this past week’s Symantec Vision 2014 conference in Las Vegas. However I have to admit, when I first glanced at some of the forecasts and charts that were included in that piece, I thought Wikibon was smoking pot and brushed it off. But after having had some lengthy conversations with attendees at Symantec Vision, I can certainly see why Wikibon made some of the claims that it did.
