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.

Customer needs are addressed effectively with collaborative sales and service support

Recently, customers have been asking for a cloud tiering option in storages. Some Dell storages do not have cloud tiering, which is an optional commercial feature. NetApp's FSA model 2750 comes with an inbuilt cloud tiering option. In the future, if Dell storages include this option, especially for Unity, it would help us target SME or medium enterprises for quicker closures and support the sales team.

Offers flexibility and top-notch technology

You can go to bed peacefully if you have a NetApp. If you have NetApp within your data center, you get to know about power failure if you are using it. Your NetApp will still come alive. Even if it does not come alive, I can say that it is not like other tools when it comes to dealing with power failure. The tool is affordable, and the technology is top-notch. It is the only technology that has software for what we call inline compression and deduplication. All the products under NetApp are aiming to use AI. I know that you can achieve whatever you want to do with NetApp EF-Series All Flash Arrays. I rate the tool a nine out of ten.

You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."

More Everpure FlashArray X NVMe pros

"Key features are ease of use, ease of management, ease of deployment, and the GUI is very user-friendly."

"It is stable, I have not personally seen any issues when deploying in a customer environment."

"The Unity 400 is one of the easiest to manage and the most reliable storage systems that I have managed in my 22 years in IT."

"VMware integration: Grants both the Storage and Virtual Administrator the ability to create and mount datastores, or even to check how much space each VM is consuming."

"For me, the best thing is the reliability."

"The high availability of Dell EMC Unity XT has been the most important feature."

"My experiences are generally positive with this product."

"Their product is stable."

More Dell Unity XT pros

"The solution allows us to segregate one storage unit from another."

"The speed is the most valuable feature."

"The benefits are better up-time, better response time."

"We do a lot of in-house, application-dependent type things, where we find the different niches to the different things. Certain things they do better. We've found that it actually does very well on some of our higher-end applications."

"The most valuable feature for us is the ability to move the workload between peers, and it also has a huge advantage of helping us cut down on power consumption."

"When we compared it to other all-flash arrays, it was the most cost-effective solution and really the most performant that we looked at."

"We have high use cases for SQL databases, most of our business critical applications use SQL to allow us to complete the DoD mission needs, so we have been using the EF-series for about two years now and everything has been going smoother and faster."

"Our use case is both corporate storage and for all of our datacenter and back-end enterprise applications."

Cons

"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."

"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."

"We would like to see VNC integration or be able to use Pure Storage with VNC."

"We need better data deduplication."

"I would like to see replication and DR features in the next release of this solution."

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

"We've seen that when we create a POD in synchronous mode, it increases the latency."

"In the future, I would like to see integration with enterprise backup systems."

More Everpure FlashArray X NVMe cons

"We have had some downtime. Nothing is perfect. Unity’s have had some code-release problems, versions that, from a compatibility perspective, had some glitches which caused an outage. But, given the amount of Unity’s we run, that has been fairly minor and it hasn't happened at scale or across all of our Unity’s."

"This product lacks deduplication and compression at the current version 4.1.0. LACP is not available for iSCSI either."

"It's not as reliable as it should be, I think it was probably released a little early. We've had production problems with customers, and there are still some challenges at scale as well. Compression is a problem for the system. Once you enable dedupe and compression, the performance of the system, the capability, halves... It has to be right-sized and sized for compression, but even with that, because there are only two storage processors, you're ending up at almost 40 percent usage."

"The solution can use improvement with the patch cluster like the Synchron and Active replication."

"The Dell/EMC merger has been challenging across the board."

"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 VNX reporting is much more granular, versus the Unity reporting."

"If you compare it with VMAX, where we communicate with the box through Solutions Enabler and there are a lot of commands and a lot of flexibility, the command line for Unity needs to enhanced."

More Dell Unity XT cons

"They could improve overall scalability through performance. Denser capacity, which is doable, it is what the competition is doing."

"I would like to shrink it more, if we can. The smaller, the better."

"There could be an improvement when it comes to SLA support, it could be faster."

"The management interface, while very reliable, it seems a little old now and could maybe use a little modernization."

"Their problems are on the software and the controlling of the storage where they lack segmentation and federation."

"There could be better integration with some of our Cisco products."

"We have used IBM previously. We found that the storage from IBM was poor and we chose NetApp EF-Series All Flash Arrays because it can scale very easily."

"The solution's technical support is not as good as it is supposed to be since you have to push them to get support."

Pricing and Cost Advice

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

"The tool's pricing is cheap; I rate it a six to seven out of ten. Most of our sales are not subscription-based. We sell the hardware, and customers keep using it. They only renew the service part annually. The support can be a bit pricey, but the solution is more cost-effective than anything else out there."

"The licensing is on a yearly basis."

"As far as the licensing costs, everything is included in the license."

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

"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."

"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."

More Everpure FlashArray X NVMe pricing and cost advice

"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."

"From a pricing perspective, this solution is comparable to others on the market."

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

"Compression is making a difference towards the amount of hardware that we need to purchase."

"Because of the attractive price, we were able to get rid of more expensive arrays, standardize, and get rid of a lot of spinning disks. We also got rid of more expensive flash that we weren't properly utilizing."

"The product’s pricing should be improved."

"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."

"It was easy to order. We are a big Dell shop, so it was easy to purchase and get it in place, then up and running."

More Dell Unity XT pricing and cost advice

"It's a lot cheaper than what the other vendors have for the same type of environment. It saves us money."

"The pricing is comparable with other competitors and similar in mid-range solutions, and for high range solutions, it would depend on our requirements or needs."

"The price point for EF is considerably lower than the alternatives."

"The pricing of the solution is expensive, considering the initial investment required...At the end of the product's life cycle, it could get cheaper, but the initial investment in NetApp makes it one of the most expensive solutions."

"Price-wise, NetApp EF-Series All Flash Arrays is costlier than Dell. You have to buy a lot of licenses separately."

"They need to improve its pricing. The storage market is dying. So, they need to improve the price because it should reach all people. NetApp is one of the top ones, and they are charging a little bit of royalty as compared to other storage solutions."

"The pricing of this solution is competitive with other vendors here in Egypt."

"he price point that we're getting is very competitive in the market. Since we are buying in such a large quantity, they gave us a huge discount."

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."
