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.

Head of Infrastructure Security (S.A.V.P) at EXIM Bank Ltd

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.

Has a fantastic feature-set and works well with workflow solutions

I would suggest, if you heavily depend on the Oracle solution from the database you should consider Oracle All-Flash because, from my understanding, it is from a single OEM, it's a single solution. It would be a homogeneous environment. I think it would be definitely a better option for customers considering other all-flash storages. It would be better if you consider a solution from Oracle, from the database studio, the storage part. I would rate it an eight out of ten. To make it a perfect ten, in the next release, I would like for it to be NVMe compliant storage.

Quotes from Members

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

Pros

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

"It has good, reliable, fast storage."

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

"The solution is scalable."

"The most valuable features of this solution are its ease of use and performance."

"The initial setup was extremely simple and straightforward."

"Everything, especially the VMs inside, is pretty fast."

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

More Pure FlashArray X NVMe pros

"It is scalable. Customers are going more into distributed architecture, so the Unity definitely has a scalable architecture built into that."

"The most valuable feature is that the solution is a hybrid system, so you can do both block and file storage."

"The fact that it's hybrid is the most valuable feature. We have the SSD so we put our SharePoint on there and some of the stuff that requires a little more speed. For SharePoint, we want the pages to respond a little more quickly. And it's nice to be able to use the slower storage for stuff that we don't need as quickly, like file servers."

"The NAS is also extremely easy to set up."

"It does great deduplication. From a storage perspective, we save money being able to dedupe right on the disk"

"It's the simplicity part of it. It's the ease of management, it's the call home, the CloudIQ functionality. It's all built in. I think Dell EMC has put a lot of thought into it."

"I like Unity XT's software-defined storage. It's a new feature that isn't widely used yet, but customers are impressed with it."

"It's easy for us to use because we use other solutions which are built for Unity, like VMware, which are recovery points. They work with the Dell EMC Unity system, as these products integrate well in our environment."

More Dell Unity XT pros

"It's actually shaking hands with the workflow solutions much better than any other storage."

Cons

"I'd like to see the product implement active replication for vehicles such as VMware."

"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."

"I would like to see some AI features that would allow arrays to intelligently identify threats or unusual behavior in the data pattern and give an alert."

"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."

"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."

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

"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 the pricing of the product."

More Pure FlashArray X NVMe cons

"In terms of what could be improved, I would say the deduplication part, because for large deduplications, you need an extra appliance to do it in order to avoid having problems in performance. I think that could be improved, because everything should be included in the product, not with an appliance from the outside."

"We had some issues recently because of a bug in the system. We were presenting LANs to the Unity array but I think it caused a disruption to the host. EMC did acknowledge it and provided an alternative way to do it."

"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."

"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."

"A customer had to buy VMX because Unity didn't have WORM."

"For the integration of the VPLEX function for Cross IDC structure, they should integrate the function into the SP controller."

"I would like the UI to look better."

"It's very frustrating that it's not backward-compatible with the previous platforms, so it's a struggle for a lot of our customers."

More Dell Unity XT cons

"It has to be flexible according to the customer's requirements. It has to be aligned with the customer business and the business environment."

Pricing and Cost Advice

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

"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."

"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."

"The licensing is on a yearly basis."

"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."

"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."

More Pure FlashArray X NVMe pricing and cost advice

"Most licenses for the solution are free but upgrades are available when adding additional software or storage."

"There is an annual charge for the license of this product. It has better pricing than its competitor: Pure Storage."

"It's an expensive solution, particularly for medium companies. One device costs about 30,000 euros. The support contract is quite expensive as well. We are currently looking for other lower-cost solutions."

"Pricing for this product is manageable, though slightly higher than comparable products."

"What they really like is the easy licensing now - Dell EMC has caught up to a lot of their competitors - based on not having to charge for everything, and they can get everything in one bundle."

"Go with the virtual appliance versus the hardware."

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

"We looked at HPE Nimble but the price of the Unity XT was very good compared to the competition."

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."
