Dell EMC announced that it will soon add Optane-based storage to its PowerMAX arrays, and that PowerMAX will use Optane as a storage tier, not “just” cache. This statement implies using Optane as a storage tier is superior to using it as a cache. But is it?
The first movie I remember seeing in a theater was 2001: A Space Odyssey. If you saw it, I am guessing that you remember it, too. At the core of the story is HAL, a sophisticated computer that controls everything on a space ship en route to Jupiter. The movie is ultimately a story of artificial intelligence gone awry.
Virtualization largely shaped the enterprise data center landscape for the past ten years. Hyper-converged infrastructure (HCI) is beginning to have the same type of impact, re-shaping the enterprise data center to fully capitalize on the benefits that virtualizing the infrastructure affords them. Enterprises considering HCI as a replacement for existing core data center infrastructure should give special attention to how the solution implements quality of service technology. Superior QoS technology will reduce OPEX by simplifying management and reduce CAPEX by consolidating many workloads onto the solution.
Across more than twenty years as an IT Director, I had many sales people incorrectly tell me that their product was the only one that offered a particular benefit. Did their false claims harm their credibility? Absolutely. Were they trying to deceive me? Possibly. But it is far more likely they lacked accurate and up-to-date information about the current capabilities of competing products in the marketplace. Their competitive intelligence system had failed them.
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.
Hyper-converged infrastructure (HCI) appliances radically simplify the data center architecture. These pre-integrated appliances accelerate and simplify infrastructure deployment and management. They combine and virtualize compute, memory, storage and networking functions from a single vendor in a scale-out cluster. As such, the stakes are high for vendors such as Dell EMC and Nutanix that are competing to own this critical piece of data center real estate.
Many organizations view hyper-converged infrastructure appliances (HCIAs) as foundational for the cloud data center architecture of the future. However, as part of an HCIA solution, one must also select a hypervisor to run on this platform. The VMware vSphere and Nutanix AHV hypervisors are two capable choices but key differences exist between them.
Hyper-converged infrastructure appliances (HCIA) radically simplify the next generation of data center architectures. Combining and virtualizing compute, memory, storage, networking, and data protection functions from a single vendor in a scale-out cluster, these pre-integrated appliances accelerate and simplify infrastructure deployment and management. As such, the stakes are high for vendors such as Dell EMC and Nutanix that are competing to own this critical piece of data center infrastructure real estate.
Some pretty amazing storage performance numbers are being bandied about these days. Generally speaking, these heretofore unheard of claims of millions of IOPS and latencies measured in microseconds include references to NVMe and perhaps storage class memories. What ultimately matters to a business is the performance of its applications, not just storage arrays. When an application is performing poorly, identifying the root cause can be a difficult and time-consuming challenge. This is particularly true in virtualized infrastructures. But meaningful help is now available to address this challenge through advances in storage analytics.
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.
If you want to get waist-deep in the technologies that will impact the data centers of tomorrow, the Flash Memory Summit 2018 (FMS) held this week in Santa Clara is the place to do it. This is where the flash industry gets its geek on and everyone on the exhibit floor speaks bits and bytes. However, there is no better place to learn about advances in flash memory that are sure to show up in products in the very near future and drive further advances in data center infrastructure.
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.
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.
Business are finally adopting public cloud because a large and rapidly growing catalog of services is now available from multiple cloud providers. These two factors have many implications for businesses. This article addresses four of these implications plus several cloud-specific risks.

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.
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.
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.
