Overview

Pure Storage FlashArray//X is the world’s first enterprise-class, all-NVMe flash storage array. It represents a new class of storage – shared accelerated storage, which is a term coined by Gartner – that delivers major breakthroughs in performance, simplicity, and consolidation.

Dell EMC Unity XT is one of the best all-flash storage arrays on the market today. Dell EMC Unity XT arrays are designed for performance, optimized for efficiency, and built for a multi-cloud world. In addition, they support digital transformation, enabling businesses to reach the full potential of their data capital quickly and easily. Dell EMC Unity’s All-Flash and Hybrid Flash storage platforms provide the performance, efficiency, enterprise-class software, and virtualization integrations required for running a wide range of virtualized applications.

Dell EMC Unity XT Features

Dell EMC Unity XT has many valuable key features, including:

  • Unified storage flexibility: With Dell EMC Unity XT you can consolidate separate storage platforms into a single Unity XT unified storage system via a simple and intuitive (HTML5) management GUI that also connects you to CloudIQ.

  • All-inclusive data protection: Dell EMC Unity XT offers a reliable way to protect application data with all-inclusive data protection services, including snapshots, data-at-rest drive encryption, replication, thin clones, and dynamic pools.

  • Software-defined solutions: Dell EMC Unity XT provides software-defined storage and HA for on-prem and in the cloud solutions.

  • Multi-cloud alignment: With Dell EMC Unity XT you have the ability to build and manage an effective data-first multi-cloud strategy. It allows you to consolidate public and private cloud resources that align with your business goals.

Reviews from Real Users

Below are some reviews and helpful feedback written by Dell EMC Unity XT users.

A Systems Engineering Manager at a manufacturing company says, "It is definitely one of the most robust, solid, well-performing products that I have dealt with. It is set it and forget it, which is pretty amazing." He also mentions, “We can do both block and file storage on one unit without purchasing a separate device.”

Peter S., Senior Technical Specialist at a healthcare company, states, “The most valuable feature is reliability. At the end of the day, it just runs. This solution is easy to work with and easy to maintain.”

PeerSpot user Melvin T., Senior Systems Engineer at Prosperity Bank, explains that the solution is “easy to use and we can add LUNs or space without interruption to end-users. We're able to access it from just about anywhere, as long as we have access to a browser. That feature is really neat because sometimes we will go to a different data center or a different site, and if we need to access it to see a LUN or to see any type of storage, we can do that. That's one of the big takeaways with Unity."

Huawei's OceanStor Dorado V3 all-flash storage is the ideal choice for enterprises' mission-critical business. It is the industry's first commercial use of NVMe all-flash storage, and it delivers high-performing, reliable, and efficient storage services.

Pure Storage FlashArray is the world’s first enterprise-class storage array that runs exclusively on the nonvolatile memory express (NVMe) protocol for memory access and storage. It represents a totally state-of-the-art type of storage technology. It offers users shared accelerated storage that delivers cutting-edge features in the realms of performance, simplicity, and consolidation. Pure Storage is fresh and modern today and will be for the next decade. Without forklift upgrades or planned downtime, Pure Storage takes the work out of storage ownership and delivers unprecedented customer satisfaction.

Pure Storage FlashArray is built with simplicity and reliability in mind. The solution can be implemented and optimized in hours, as opposed to other similar solutions that can take days. It has no moving parts, which removes areas where it could potentially be vulnerable to suffering errors. It is highly stable and gives users the ability to manage system shutdowns in a way that  prevents data loss.

Benefits of Pure Storage FlashArray

Some of the benefits of using Pure Storage FlashArray include:

  • A much higher level of speed than similar pieces of technology. Pure Storage FlashArray maximizes the speed at which data can be transferred while at the same time minimizing system latencies that might slow the transfer down. Additionally, it offers users quick memory read and data access speeds.

  • A higher bang for your buck in terms of the storage capabilities you get for the money you pay. They are smaller in size than more standard storage technologies, but they offer flash memory, which enables users to store larger amounts of data than the current standard.

Reviews from Real Users

Pure Storage FlashArray is a highly effective piece of storage technology which stands out among its competitors for a number of reasons. Two major ones are its overall robustness and the value that it offers by way of its reliability and ease of use. It provides users with many valuable features that allow them to maximize what they can do with this solution. Pure Storage FlashArray’s reliability and ease of use make it a highly valuable solution. 

PeerSpot user Prabakaran K., a technical consultant at Injazat Data Systems, notes the robustness of this solution when he writes, "FlashArray has many valuable features. It's very user-friendly and it has high availability, so there is comparatively less downtime. During maintenance, there is no shutdown procedure, so you can directly power off the Array and manage the shutdown process without any data loss, which is a unique feature. Managing replication and data migration is also very easy."

PeerSpot user Jason D., a cloud solutions architect at a tech services company, notes three features that make this solution valuable when he writes, "We've had different types of storage, and three things of this solution are valuable. The first one is its outstanding performance. The second one is its stability. In the about three years that we've had it, we've had component failures, but we never had a service interruption or any data loss. The third one, which is really critical, is that it is super easy to use in terms of provisioning, storage, and managing the arrays. I'm able to maintain a multi-site environment with a couple of dozen arrays with a single mid-level storage admin."
