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.

Quotes from Members

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

Pros

"The best features of Pure FlashArray X NVMe include the volume snapshot capabilities, which allow us to save most of the storage space by volume snapshots periodically."

"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."

"The most valuable feature of this solution is its ease of use."

"The solution is very straightforward to set up."

"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."

"The initial setup was extremely simple and straightforward."

"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."

"One of the best features is the support, which is excellent."

More Pure FlashArray X NVMe pros

"Using this solution has meant that I do not need to look for different partners to provide me with solutions like a backup service. Dell provides end to end solutions."

"We can get almost real-time response times."

"It's unified, it does block and file, so that is pretty important to my customers who might have file servers around their environment. I can roll them all up into a single array, as well as provide block storage for them on one array."

"The flash aspects of the Unity make it incredibly fast. The fact that you get that much storage directly on what is basically a 3U box to us, that density has been really useful."

"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."

"I like the easy management with the new Unisphere management and the HTML5 interface."

"It's easy to use, easy to manage, easy to troubleshoot, and the process support is good."

"We like the way it integrates with our environment. These features help us use multiple soft applications. The new features of going off the grid and replicating really help us. They give us an advantage versus traditional storage resources."

More Dell Unity XT pros

"It's a very compact device. For a medium-sized business, it's very helpful because the device is efficient and very fast."

"Overall performance of the solution."

"We can add a node, we add compute, we add storage, and we've had really good luck with that."

"The square footage for doing development is at a premium when dealing with government networks. To be able to put a lot of IOPS in a lot of high-speed performing drives in a very small location which requires very little HVAC with very little power, it is very valuable to us."

"SolidFire is one of the products that does have great APIs right out-of-the-box. It works great. The tools and the other stuff seem to work a little better right out-of-the-box than the ONTAP stuff does, C-Mode."

"Individual settings you can put on each individual volume, if you want to do that."

"If we get complaints about any kind of performance metric issues, whether it's storage related or something on the virtual side, we use it to pinpoint what the actual issue is."

"If you buy the solution for its specific purpose it will work well."

More SolidFire pros

Cons

"It is on the expensive side."

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

"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."

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

"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."

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

"Maybe the price can be reduced since the solution is very expensive."

"There is room for improvement in the pricing of the product."

More Pure FlashArray X NVMe cons

"It would be great if the solution could integrate an NVMe disk."

"Ordering is easy, but the processing site and working with those companies was difficult."

"The user interface could use improvement."

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

"Dell could improve Unity XT by adding support for NVMe."

"I would like it to be a little bit easier to contact support. We can contact support, but we have to go through a phone tree. We get routed to different places. I might call support to say that I need a drive replaced and get transferred to three different groups before I get to the group I actually need."

"My only complaint would be some of the CLI Help files could be a little more detailed, but that's very minor complaint. We were trying to run some commands just to see how the storage snaps were interacting with the storage array, and it was a little difficult to look up exactly what commands should be run. The Help files detailing what exactly the commands did wasn't as detailed as we would have wanted them to be."

"One area of improvement is replication. We are also using Oracle virtual machines, and when you are using systems from other vendors, the process of replicating from Unity through OLVM is more laborious than when we were using VPLEX."

More Dell Unity XT cons

"A little better segregation of the multi-tenancy. Right now, it's just VLAN-specific, that's all you can do."

"They could do a file-based NAS: SolidFire NAS-based. It's probably not its niche, but that is our direction, not to use block, and it's block. Solid state block is what it is."

"The scalability of HCI or SolidFire as such isn't a concern, but when you compare it to PowerMax or NetApp AFF series devices, scalability is a concern because it's only the drives that are connected to the nodes. We don't have any shelf connectivity."

"The tool should improve its initial cost which is expensive compared to other products."

"The upgrade process could be better."

"When you set up the nodes, we have to serial into each one of these nodes to configure the IP ranges. It's still very easy, but it's time consuming."

"One of the challenges we faced while using SolidFire was that the product line that we were using in our company was discontinued."

"Though it is a stable solution, its users may face some security issues at times...The security provided by the solution is one area that can be improved."

More SolidFire cons

Pricing and Cost Advice

"The support cost per array is about $20,000 a year for 24/7 support."

"The licensing is on a yearly basis."

"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."

"The tool is an investment that we've budgeted for. While the prices may be higher than those of other vendors, we see it as a market leader with benefits. We don't regret purchasing it."

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

"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."

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

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

More Pure FlashArray X NVMe pricing and cost advice

"Licensing is a little bit confusing. Going through everything with them, there are a lot of line items to go over. Every single thing is broken down into a line item, and it starts to get really confusing in terms of what we're actually purchasing when it comes to the product."

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

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

"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.""

"Just from an overall power and heating usage, it costs substantially less than some of our existing solutions"

"Pricing is as high as it has ever been for EMC."

"Obtaining a warranty is easy."

"Licensing is fine. We worked with a sales rep to purchase our Unity."

More Dell Unity XT pricing and cost advice

"The price of this solution is more expensive than others."

"Based on what I heard from other people, its price was on the higher side."

"We would probably use SolidFire more, except we're getting more bang for our buck with our purchases of ONTAP right now, and the deal we made with NetApp, so it's more of just a cost decision"

"On a scale where one is a high price and ten is a low price, I rate the solution between three and four. It is an expensive solution."

"It might be considered expensive, but when evaluating performance, it represents good value online because you pay for what you get."

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."
