Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"The high performance is very valuable, as well as the enterprise reliability features.""There's lots of flexibility in how we use the resources while also maintaining a small footprint.""We have been able to consolidate storage into Pavilion. Pavilions are our only SANs because it is a bring your own disk solution. When new drives come out, we are able to take out half of the drives in the system, put in new drives, move our VMs over to the new drives, take the other drives out, and populate those with new drives. Then, we are suddenly twice as dense as we were before. NVMe flash is only going to get denser and cheaper so we can make use of that every couple of years by just throwing newer disks into it at a fraction of the cost of a new SAN."

"The setup and installation procedures are easy.""This solution is easy to work with and easy to maintain.""The high availability of Dell EMC Unity XT has been the most important feature.""The most valuable features include snapshots, Thin Clones, and deduplication and compression.""The feature that I have found most valuable is the unified storage. Also, its capabilities for block-access, file access, and the center box.""The most valuable feature is the dynamic cache of this product. It is very important. We have the physical cache and we can boost this cache using disks. All the products are mainly flash now and this is one of the main characteristics which our customers like.""I have had no problem at all. I think this is one of the most important things. It is very good. Maintaining it and deploying updates require very low maintenance. We haven't had problems. We had to replace a couple of disks in all these years, but it was pretty straightforward.""We are happy with the way we have Dell EMC Unity XT configured."

More Dell Unity XT Pros →

"I like FlashArray's ActiveCluster as well as its snapshot and cloning capabilities.""The most valuable features are the replication of data and the continuous snapshot that we can take from the disc.""I use all the features of this solution and I find them to be easy to use and functional, such as the compression and capacity to expand.""The technical support is very good.""We're getting good performance, and the compression ratio is also very good in Pure Storage FlashArray.""Processes that used to take 40 minutes to two hours can be completed in five minutes.""Access speed and power consumption are most valuable.""The speed is one of the most valuable features of Pure Storage FlashArray."

More Pure Storage FlashArray Pros →

Cons
"I would like to see the management layer improved.""In our current configuration, we can only run the line controllers in high availability, active-standby mode, whereas we would like to see active-active implemented.""The rail system that Pavilion uses to mount up into a standard Dell or APC cabinet extends further back than normal rails, and they cover up the zero PDU slot. So, I don't like the rail system that comes with the device. That is my biggest complaint."

More Pavilion HyperParallel Flash Array Cons →

"The reporting should be better. In other systems, you can create many different kinds of reports but this is not the case with Dell.""We have only used this solution for less than one year so I don't have any improvements suggestions yet.""Support Responsiveness & time to fix bugs should be improved.""Scalability of this solution could be improved.""Our request to Dell EMC for improvement was in the reporting and monitoring areas. Dell EMC built up a cloud ID so that we could see the overall storage numbers. We needed to have the proper KPIs to be able to see and manage things.""The price of this product can be more cost-effective.""This product has some scalability issues. Before you can get support, you have to look for the service tag number on your product which could make it difficult to access support.""Having more artificial intelligence tools built into the solution would be a great benefit. This would allow us to see more about the workloads and higher visibility, such as performance degradation."

More Dell Unity XT Cons →

"The backend of this solution utilizes an Active/Passive architecture, rather than an Active/Active architecture, which is a disadvantage, when compared to some of its competitors. Its storage capacity should be expanded in the next release.""A minor issue that comes to mind is that, every once in a while, a hard drive will go bad.""Data reduction is an area that needs improvement. There is a garbage collection service that runs but during that time, system utilization increases.""Beyond a certain amount of petabytes, you have to have a separate system. Basically, it's not infinitely scalable.""The problem is that we can only make a few groups, around five or six groups. I like groups and we need a lot of them. We had to put all the information in only a few groups and cannot make a more detailed separation of them.""We need to add more storage in Pure Storage FlashArray with the cluster mode activated for us to have better performance.""Its price needs improvement. Its price is almost double than any other flash storage solution.""When we were doing some tests, we found that there was an I/O freeze when they were switching the controller."

Pricing and Cost Advice
  • "This is hardware. They have a singular array that you can populate with your own disk, or you can buy the disks through them. For controllers, you pay for the components inside of the SAN, but there is only one chassis that they work with."
  • "The licensing fees are very reasonable."
  • More Pavilion HyperParallel Flash Array Pricing and Cost Advice →

  • "The price of Dell EMC Unity XT is higher compared to other solutions. The price should be less expensive."
  • "Pricing for this product is manageable, though slightly higher than comparable products."
  • "The solution is very expensive."
  • "The solution is very expensive."
  • "This solution is a good price for what you get."
  • "Here is our major complaint with pricing. Dell EMC comes to us and gives us a price. We are like, "Well, this doesn't even compare to what we got on the last project." We say, "No, you should bring it down to this level." Then, they come back again and we are sort of in the middle again. I am like, You already sold us other stuff at a better price. We are not going to just say, 'Yes,' because we are out of time.""
  • "I liked the price point when we purchased it."
  • "We looked at HPE Nimble but the price of the Unity XT was very good compared to the competition."
  • More Dell Unity XT Pricing and Cost Advice →

  • "Its price is almost double than any other flash storage solution."
  • "The price, in general, is around $100,000, however, I know it costs more."
  • "They have a standardized fee; it's been the same price for 10 years straight. I am happy with the price — I think it's good."
  • "We do not incur additional costs beyond the licensing fee."
  • "My organization has a yearly license, but I believe that Pure Storage FlashArray has capacity-based licenses as well. I'm definitely happy with the pricing."
  • "There is an annual or perpetual license required for this solution."
  • "Pure is typically more expensive than everyone else. You get what you pay for, but I have lost deals to similar solutions because of pricing. They include everything, and that's another positive about Pure Storage. They aren't trying to nickel and dime their customers for different features. It is all included in one price. The license is by capacity, and the price depends on the capacity and the discount we're getting from the vendor. You get the SKU of the physical appliance, support, and maintenance, and that's it. You're licensed for whatever feature they offer. It is all rolled up into the price of the appliance."
  • "The pricing is reasonable."

    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."
