Supports efficient storage management through volume snapshots and offers reliable non-disruptive upgrades

I have no specific improvements to suggest for Pure FlashArray X NVMe at this time. The performance statistics could be enhanced. I can see the performance statistics in the Pure Storage console, but it does not show the performance by 4K byte unit. It displays IOPS and bandwidth, but IOPS is about real use, and I want to know how many IOPS are currently running in 4K byte units. I cannot see that IOPS because most storage systems report their performance by 4K byte unit. I want to see Pure Storage performance by 4K byte unit to compare with other storage or other internal NVMe SSD.

Efficient data replication and fast IOPS have improved operational performance

Dell and a partner jointly implemented this solution in Auvink. We installed the Flash, which makes our IO operations fast and efficient. Replication is available, allowing us to replicate data simultaneously from one site to another. All-flash technology and vTXT enhance speed, and the IOPS are faster. The cache's IOPS are much better. Snapshots provide a unique feature for testing and make management more comfortable and easy. The platform is multi-supported and certification is more convenient and easy to manage.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."

"What I really like about this program, is that it is easy to use and easy to configurate."

"The most valuable feature of this solution is reliability."

"The solution is very straightforward to set up."

"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."

"The solution uses newer technology for deduplication and compression."

"The database workloads are pretty fast because I frequently move data from here to there."

"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."

More Pure FlashArray X NVMe pros

"It's an all-flash Unity, With that compression feature, it's comparable to a hybrid. That is one thing that we definitely like."

"Stable flash storage platform with good scalability, efficiency, and speed."

"The way it takes the Snaps, that is one of the best features. Snapshot performance is what is key in the Unity, compared to a traditional VNX."

"Dell excels in service and support."

"It has a very intuitive web console that runs in HTML5 and makes navigation and administration fairly easy."

"A lot of the Unisphere interfaces are greatly improved in terms of monitoring capabilities, alerting, and ease of use. Setting up the storage and the file system are all just a few clicks away."

"For our customers, it's the simplicity of it. They find it easy to use, along with the added features, the dynamic volumes."

"Storage Snapshots have been really nice. They allow us to do backups without impacting our production workload that much. The scalability, the ability to add disks dynamically and adjust our workload as needed, has also been really helpful. That definitely makes my job easier. And the interface for managing Unity is very easy. The integrations between VMware Hypervisor and Dell EMC are top-notch, so it's been really easy to use and manage."

More Dell Unity XT pros

"The speed and scalability of Dell XtremIO are significant features that improve data storage management."

"We've seen great enhancements from the performance point of view. There's good availability, stability, and continuity, but the performance actually has increased by 60 or 70%."

"Speed and reliability:"

"Scalability is a significant feature of Dell XtremIO, as it is easy to expand and manage."

"The performance is good, which is important."

"Performance and deduplication. This is a very robust block storage option that offers both performance and data optimization."

"The solution's most valuable feature is its high performance."

"The most valuable feature of the solution is its performance."

More Dell XtremIO pros

Cons

"In terms of what needs improvement, the dashboard and management could be simplified."

"In the next release, I would like to see real-time analytics for further insight into consumption models."

"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."

"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."

"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."

"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."

"It feels more suitable for small and medium-sized businesses rather than enterprises."

"They could add more support for file storage and different types of storage."

More Pure FlashArray X NVMe cons

"Things that could be improved include one-to-many replication, data deduplication, and asynchronous Fibre Channel replication. It is asynchronous on iSCSI and I would like to have that on the Fibre Channel. Unisphere-wise, I have to log in to each Unity as a unique environment. In VNX, I logged in to the domain and I was logged in to every VNX. So that's missing."

"It is missing some features, like deduplication."

"I think there are a couple of things on the file side that we're lacking from the VNX world. It would be nice if we got some of those back. I think there are limitations on how many file systems you can back up at a time. Whereas you can do, I believe, eight continuous per data mover on the file side on the VNX, you can only do something like two or four on Unity. If they could step up to that, that would be good."

"I would like to see them add Storage Groups, like we have had in Clariions and VNXs."

"Include cloud-based replication for blocks"

"The technical support sometimes takes three to four days to get hardware to facilities. I would rate customer service four out of ten."

"There are a lot of things that can be done with it. It's got Cloud IQ, but I think it's not as mature as it could be, they could make it more effective. They could make it more comparable to some of the other products out there that have cloud analytics. The amount of insight that the Unity product is able to give, at this point, is okay, but not class-leading. Some of the other data-reduction technologies, like deduplication, are not to the level of other competitors and what their products provide."

"I haven't seen the roadmap for this solution."

More Dell Unity XT cons

"XtremIO is coming to its end of life."

"I would like to see more scalability."

"XtremIO needs to be lower priced. It also needs better endpoints and scalability."

"The management should be improved and the GUI interface could be better and easier."

"The product could be improved by reducing the pricing and having better organization in their technical support team."

"They can improve the product by providing an HTML5-based interface instead of the Java GUI based application."

"The interface could be simplified for beginners to ease the configuration of special objects in the system."

"Scalability is something that can be improved because there is an issue when it comes to mixing versions."

More Dell XtremIO cons

Pricing and Cost Advice

"Pretty much everything that you need is licensed when you buy the product. Licensing to me is different than the maintenance cost, but they can bleed into one another. We buy the product, and we expect three years of support bundled into what we negotiate on our storage arrays. I would start to see maintenance costs going into the fourth year, but we're not there yet."

"Our licensing fees are $500,000+ USD."

"Given its price, Pure is not the first option."

"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."

"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."

"Pure FlashArray X NVMe’s pricing is cheaper than other products."

"The licensing is on a yearly basis."

"We pay approximately $50,000 USD per year in licensing fees."

More Pure FlashArray X NVMe pricing and cost advice

"Looking at it based on cost per gigabyte, it's certainly very effective."

"Our costs are roughly $200,000 a year."

"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 solution is very expensive."

"One of the most valuable features is its cost. It was inexpensive compared to other arrays that we were looking at."

"Its biggest valuable feature is its price point for the amount of storage and performance you get. It's a sweet spot. It's cheaper than the other SANs out there, but performs well enough. It fits that nice, middle-ground portfolio."

"The flexibility is important. We still have a lot of customers that have a use case for non-flash, yet you can also build the flash version as well."

"The price of Dell Unity XT could improve. However, it is a one-time purchase."

More Dell Unity XT pricing and cost advice

"Don’t buy this array. You’re paying for loads of magic beans, since it’s mediocre at best for a platform in a rapidly growing field. Look instead at Pure Storage or something with variable block deduplication. You’ll end up spending less and getting a better product with actual support."

"XtremIO is an all-flash array, which means it's a costly solution. When compared with general mid-range storage solutions, this is more expensive. As far as I know, there are no additional costs besides the license."

"XtremIO is pretty straightforward about pricing. However, you need to look at your data so you can estimate, with the advice of DEL EMC, what data reduction ratio you will reach. In our case, a 3:1 reduction ration gave us a positive case compared to other storage arrays."

"Pricing and licensing are in line with other products from other manufacturers. You get what you pay for."

"It is expensive if you need to increase scalability."

"It is great when a product can deliver high-end performance capabilities while offering a very competitive price point."

"The initial purchase price was good but when you need to upgrade, it's a different story."

"This solution is a little bit pricey."

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."
