More Pure FlashArray X NVMe Pros →

"The benefits are the simplicity, flexibility and the ease of integration between the Unity platform and VMware, for example, and Microsoft platforms; the integration tools and the simplicity of management.""I like the integration into VirtualCenter. I used to have to add LUNs manually, then scan them in and format them. It does that all for you, all in one, immediate deployment of LUNs.""I don't think I've ever seen latencies above 10 milliseconds unless it was something that wasn't the array that was messing up. The thing is rock-solid.""All-flash array eliminates all the overhead of tiering and a lot of the data structuring overhead involved.""We can sleep at night because the support is great.""The most valuable features include snapshots, Thin Clones, and deduplication and compression.""The inline deduplication and data reduction capabilities have been the most valuable.""The storage management is superb, with a user-friendly graphical interface and dashboards.

Cons
"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure.""Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution.""We would like to see VNC integration or be able to use Pure Storage with VNC.""Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe.""I'd like to see the product implement active replication for vehicles such as VMware.""We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly.""There is room for improvement in the pricing of the product.""In the next release, I would like to see real-time analytics for further insight into consumption models."

More Pure FlashArray X NVMe Cons →

"The VNX reporting is much more granular, versus the Unity reporting.""What I'd like to see is a little more detail on the networking side. I can go into where it's showing me the replication, but when I go into the network it just gives me broad-based information. I don't know which replication job is actually feeding it. I have to go in and rely on other apps.""Unity only does compression. It would be nice if there was a deduplication feature as well. At my previous job, we used XtremIO and that was deduplication and not compression, and I think we got more out of it because the more OSs you have that are the same, the fewer copies it needs to keep of all that data. So, the deduplication would be a nice feature to have.""It could be improved in the area of management flexibility. For example, I really need to set read-only access for LUNs, and there's no such option with Unity XT.""The interface and configuration could improve.""I have a problem because between the Unity XT and the PowerMax, sometimes we need another product between these two products. There could be better integrated and the capacity of the size could be larger.""Replication with VMware - it's called the vSphere Metro Storage Cluster - is lacking in the Unity and is present in Compellent.""I would like to see more integration with other products."

More Dell Unity XT Cons →

"I recognize it's a difficult challenge, but I would like to see them make the pricing more reasonable.""I would like to see more cloud integration.""When we were doing some tests, we found that there was an I/O freeze when they were switching the controller.""The scalability of the solution is not as good as it probably could be.""Part of our company works on Dell EMC because Pure Storage did not have synchronous applications when we were purchasing our products.""Some services could be inserted directly into the SAN, so Pure Storage could complete with the HyperFlex.""We need to add more storage in Pure Storage FlashArray with the cluster mode activated for us to have better performance.""I would like to see the NAS add-on component become more fault-tolerant than just a single virtual machine running inside the array. I'm unwilling to use it for that reason."

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."
  • More Pure FlashArray X NVMe Pricing and Cost Advice →

  • "The price is good for commercial grade storage arrays."

  • "This product is cheaper than the EMC VNX solution. It is good for small businesses."
  • "It is shipped with all licensed, included for this product range, no need to buy additional licenses"
  • "The only improvement would be a lower cost per unit/disks, however on the whole we are very pleased with this product."
  • "For costing, you have to have a budget in mind because SANs can be fairly expensive and EMC offers a wide range of products."
  • "The pricing was quite okay compared to others. We probably got it cheaper because we were the first ones out of the gate, but I would say that it's good value for the money."
  • More Dell Unity XT Pricing and Cost Advice →

  • "We feel that the pricing is fair and the licensing process was easy for both."
  • "There is always room for negotiation."
  • "The price was slightly higher than others, but competitive, if you consider all the other features that you get from it."
  • "It is a more expensive solution, but it is worth it. You are getting what you paid for."
  • "For pricing, you have to take into account their performance on deduplication and compression in a $/GB comparison."
  • "We have seen a reduction in total cost of ownership (TCO)."
  • "It is a cheaper solution."
  • "Pure Storage is all-flash, so this sometimes tends to make it a bit more expensive in the beginning."

    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 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."
