Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"It is an SSD array that has awesome performance, low submillisecond latency, and does what it is supposed to do. It just works, which is difficult for things to do anymore.""Their support system has insight into errors on our SAN fabric that we can't see. They've brought attention to and raised awareness for us about things that we couldn't see, when we were experiencing problems.""It is fast and reliable. It works.""It's simple, powerful, and ready to use.""The speed is the most valuable feature of this solution.""The first set up we had was really straight forward and simple.""We also use VMware integrations developed by Pure, their plugins in our vCenter environment. They help by allowing our non-technical operations teams to deploy new data stores and resize data stores without me having to involve myself all the time to do those simple tasks.""The scalability options are very nice because you can scale it much better and faster. The scalability was there in the previous environment also, but this is far better than what we had before. It basically helps the user in case they are looking for more storage. We can scale it much faster."

"The most valuable feature of Dell Unity XT is the GUI, it is very good. End users can manage using it. Additionally, the documentation is of high quality and it integrates well.""Unified block and file storage without the need of control stations and data movers. This simplifies administration and deployment and requires less rack space.""For our customers, it's the simplicity of it. They find it easy to use, along with the added features, the dynamic volumes.""The inline deduplication and data reduction capabilities have been the most valuable.""The performance is great. We have four or five different Unity arrays, and they have all run flawlessly.""The most valuable features are its performance and simplicity.""I like that when you log in it gives you a dashboard of what your storage looks like.""Scalability is good."

"The latency is good.""Technical support has been helpful and responsive.""The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability.""It has benefited my organization because it has reduced time to insights.""The high availability of the product is the most valuable feature.""We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion.""The initial setup was extremely simple and straightforward.""The most valuable feature of this solution is its ease of use."

Cons
"With scalability, I have run into a little problem with our last upgrade. There were some undocumented limitations to the number of drives that our controller could run on. So, instead of putting in a new data pack as we had anticipated, we had to keep adding and removing to get up to the capacity that we needed to be. What should have been a one day process (or a few hours) turned into a month and a half process.""It would be nice to have a better view of the allocated capacity on their Platform as a Service solution because we have to do some manual calculations to understand how much we are going to pay every month to use the storage that is allocated.""We've had it in place for about a year and a half and have had zero complaints, other than that box-to-box replication is not encrypted.""The price should be lower.""The number of Filesystems is limited, which it is not on the EMC VNX.""FlashArray's capacity for forecasting should be improved because it needs to be a bit more current. I think it's bundled with the deduplication and other compression factors. We need more user interfaces for forecasting in this software and more interfaces need to be integrated with this array management tool.""I had to contact customer support when a drive failed as I was doing a couple of OS upgrades.""Beyond a certain amount of petabytes, you have to have a separate system. Basically, it's not infinitely scalable."

More Pure Storage FlashArray Cons →

"I don't know where the hybrid cloud might be going or what connectivity there is between what was recently released as far as AWS and being able to manage both of them. Maybe there is an on-prem and an AWS instance in the same window, like a single pane, but I would like to see something along those lines, where there wouldn't be two locations to manage storage.""We had one incident with a memory leak that led to controller reboot. Although it had no impact, when such things happens the storage should be more aware of it, send alerts, and propose corrective actions.""We would like to see the concept of Storage Groups brought back to this product line.""VNX used to have some features that Unity still doesn't have. From that perspective, the progress is not that advanced.""We'd like to see a cheaper version of an all-flash array in that footprint.""​Improve the interface and provide more management capability.""Licensing has been quite difficult. It doesn't always auto-license. About half the time, when I provision one, I have to contact Service to get a license, or even go to our account manager to help get it straightened out.""The only challenge I've ever had was with a Drive firmware upgrade."

More Dell Unity XT Cons →

"I would like to see replication and DR features in the next release of this solution.""The tool's portfolio is minimal. It is expensive.""Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe.""We would like to see more visibility into garbage collection and CPU performance in the GUI.""The software layer has to improve.""We need better data deduplication.""Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services.""Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."

  • More Dell Unity XT Pricing and Cost Advice →

  • "With Pure Storage, we would like to continue seeing price reductions with flash storage. I don't think we're any different than anybody else when we continue to look to the industry for price reductions of both NVMe and traditional SSD storage. We would like to see these prices continue to decline and erode, even displacing large spinning disks."
  • "We pay approximately $50,000 USD per year in licensing fees."
  • "With VMware, we pay $300,000 annually."
  • "Our licensing fees are $500,000+ USD."
  • "As far as the licensing costs, everything is included in the license."
  • "They can tout the functionality and cutting edge technology that they have, but that's where the price tag comes in. The cost is high, but I think as they grow their business and get more customers that it will probably go down a little bit."
  • "Its price could be better. It is not too expensive, but it is the high-end cost. It is kind of a Rolls-Royce. You pay a lot, but you get a lot out of it. So, the price pressure on the way down would be great, but at the end of the day, if you need to do the work, you just pay for it."
  • "The licensing is on a yearly basis."

    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."

    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."

    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.
