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.
One would think that with the continuing explosion in the amount of data being created every year, the number of appliances that can reduce the amount of data stored by deduplicating it would be increasing. That statement is both true and flawed. On one hand, the number of backup and storage appliances that can deduplicate data has never been higher and continues to increase. On the other hand, the number of vendors that create physical target-based appliances dedicated to the deduplication of backup data continues to shrink.
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.
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.
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.
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.
The shift is on toward using cloud service providers for an increasing number of production IT functions with backup and DR often at the top of the list of the tasks that companies first want to deploy in the cloud. But as IT staff seeks to “Check the box” that they can comply with corporate directives to have a cloud solution in place for backup and DR, they also need to simultaneously check the “Simplicity,” “Cost-savings,” and “It Works” boxes.
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.
VMworld provides insight into some of the biggest tech trends occurring in the enterprise data center space and, once again, this year did not disappoint. But amid the literally dozens of vendors showing off their wares on the show floor, here are the four stories or products that caught my attention and earned my “VMworld 2018 Best of Show” recognition at this year’s event.
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.
When organizations deploy HCI at scale (more than eight nodes in a single logical configuration), cracks in its architecture can begin to appear unless organizations carefully examine how well it scales. On the surface, high end and standard hyper-converged architectures deliver the same benefits. They each virtualize compute, memory, storage networking, and data storage in a simple to deploy and manage scale-out architecture. They support standard hypervisor platforms. They provide their own data protection solutions in the form of snapshots and replication. In short, these two architectures mirror each other in many ways. However, high-end and standard HCI solutions differ in functionality in ways that primarily surface in large virtualized deployments.
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.
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.
