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.

Runs smoothly and provides excellent performance and throughput

I love the SnapMirror and autonomous ransomware protection features. SnapMirror is used for replication purposes in a DC/DR setup. If something goes wrong with the data center or production DR, the data automatically gets replicated to the DR site, and the DR site becomes operational, allowing continued access to data. Autonomous ransomware protection helps recover data in case of any threat or ransomware. Ransomware is increasing daily, and according to Gartner, most companies have to pay a ransom if a ransomware attack occurs in their environment. NetApp provides a ransomware guarantee program where they commit that if data cannot be recovered in case of ransomware, NetApp will provide compensation, which adds significant value.

Quotes from Members

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

Pros

"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."

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

"We are satisfied with the performance as it is significantly faster compared to traditional storage options."

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

"Overall stability is very good. It is a very stable solution."

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

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

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

More Pure FlashArray X NVMe pros

"Their support cases are all handed through the portal. The support contacts me when they need to do upgrades. It has been great. It's all very well-handled, scheduled, and performed."

"I think Dell Unity XT is one of the best options on the market at the moment, although there is some good competition."

"We use it to implement all our VDI solutions."

"The most valuable feature of Dell Unity XT is its support of protocols for both block, and file levels. It has the features a store solution should have."

"Unified block and file storage without the need of control stations and data movers. This simplifies administration and deployment and requires less rack space."

"My storage team likes Unity's replication features. Three-site replication is a unique feature that EMC offers us."

"It is pretty stable. I like the stability, because everything works like it should. We made it all redundant. So, we don't have anything to worry about."

"Dell EMC Unity XT has good integration with VMware."

More Dell Unity XT pros

"Their dedupe functionality is probably the best in the industry. We also find their support model to be good. When we purchase something, we have a very good understanding of how long that product will be supported by them. That helps."

"I love the SnapMirror and autonomous ransomware protection features."

Cons

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

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

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

"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."

"Adding some functions to the product would be beneficial."

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

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

More Pure FlashArray X NVMe cons

"In some countries, spare part availability is an issue for us."

"It could be a little easier to attach it to a network file system."

"As the solution continues to grow and gain more traction, things will come up that will just continue to deepen the integration between VMware, vCenter, and all those other components. Anything in the divisibility there and additional tools is always great."

"Maybe deduplication would be something that would be better to have. Also, it's a fairly new management interface, so work is still being done on that. But compared to other vendors and previous EMC storage, the Unity is really good."

"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."

"VNX used to have some features that Unity still doesn't have. From that perspective, the progress is not that advanced."

"There is an issue with data duplication occurring on the flash memory. It should be improved. Timely updates and upgrades to the latest versions would be great."

"We cannot connect directly with Dell due to sanctions."

More Dell Unity XT cons

"I'm handling pre-sales and post-sales. From a partner's point of view, the tools that I'm using to create the quote or do the sizing are very slow. The tools, such as hardware universe, fusion.netapp.com, and partnerhub.netapp.com, operate very slowly. These tools should be more efficient as they enter a hung state repeatedly."

"I would like to see more in terms of replication between storage classes. They provide different lines of storage. They have a lower class. They have a capacity class. They have their enterprise class. Currently, we have interoperability at the same plane with ONTAP, but we would like to see some more mix-and-match features."

"From a partner's point of view, the tools that I'm using to create the quote or do the sizing are very slow."

Pricing and Cost Advice

"With VMware, we pay $300,000 annually."

"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."

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

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

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

"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."

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

"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."

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."

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

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

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

"When I see other products—like HP, Huawei, and Lenovo—from competitors, I have seen a lot of disadvantages with EMC, price-wise. Huawei and Lenovo are very price competitive. Looking at the price point for a country like Sri Lanka, where we have a very low economy, I think you need to look at a pricing mechanism that is a bit more flexible."

"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."

"Our CAPEX was close to $42,000 and operating costs are below $1000."

"From an ROI perspective, I'll put it this way: When we've tried to buy other SANs, the Unity ROI makes it impossible to buy them. So usually, the only time we buy another SAN is when the ROI isn't a factor, because Unity can't do the job. From an ROI perspective, it's great because it beats everything else out. We've tried to look at other options but, at the end of the day, when you price it out, the Unity wins."

More Dell Unity XT pricing and cost advice

"It is pretty good. It is definitely cheaper than Dell EMC. It is cheaper than Pure. It is cheaper than VAST. It is definitely cheaper than HPE. The only one that is on par with NetApp's pricing for enterprise customers is IBM."

"It's more expensive than other storage vendors such as Dell, Pure Storage, HPE, Lenovo, etc. It provides the value, but some of the customers don't look at the value. They first look at the cost. It should be reduced by 20% to 30%."

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."
