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.

Performance and interface improve data processing speeds but require complex configuration

The most valuable features of VMAX are its performance and GUI interface. We have seen significant improvements in technology over the last four to five years. The snap feature, along with deduplication, has notably enhanced our data processing speeds. We haven't experienced any outages or core-level issues in the last ten years, making us comfortable with the storage solution.

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 has low latency and high Ops. It is an evergreen model."

"The latency is good."

"Technical support has been helpful and responsive."

"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."

"The tool's valuable features are speed, security, data compression, and reliability. Its data compression feature is the best that we have ever seen. It helps us to save money and resources."

"The high availability of the product is the most valuable feature."

"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."

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

More Pure FlashArray X NVMe pros

"The valuable features of Unity include that it's flexible, has a friendly user-interface, and provides good performance."

"We run about 100 virtual servers on it. We have about 100 users accessing the file shares from there, and I've seen no problem with that. We have about a 10GB backbone. Whatever we throw at it, it hasn't shown any sign of weakness or anything. It's been really good."

"I like that the performance is very good."

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

"Veeam Backup integration: Veeam is the defacto standard for backing up of virtual environments."

"It is very user-friendly to read and determine the exact problem, unlike HP where different tools and L3 team support are needed."

"Its main advantage over vSAN was the rebuild, the intelligence of the restoration in the event of a hardware drive failure and, of course, the all-flash solution."

"The Snapshot feature is key."

More Dell Unity XT pros

"The product's initial setup phase was good."

"The ransomware protection feature is housed in a separate unit, specifically addressing the top twenty most critical threats."

"We haven't experienced any outages or core-level issues in the last ten years, making us comfortable with the storage solution."

"The snapshot feature has been precious for our testing processes, application development, and managing testing environments due to its efficiency and ease of use."

"The most valuable features of VMAX are its performance and GUI interface."

"It works very well."

Cons

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

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

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

"The tool's pricing is higher than competitors."

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

"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."

"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."

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

More Pure FlashArray X NVMe cons

"The only issue is with the product's scalability because it's not as scalable as the other polished tools in the market."

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

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

"We've got massive issues at the moment with IBM AIX. It's not stable. We have a lot of disk errors, production crashes sometimes."

"The pre-sales technical support and technical engagement could be made better for this product."

"This solution could be improved by offering containerization. This is something many of my customers are looking for."

"Dell EMC's competitor has a clustering technology. In the next release, it would be nice if they could build that into the product."

"They can certainly improve in terms of monitoring."

More Dell Unity XT cons

"Improvements are needed in both partition recovery and scalability."

"There is room for improvement in the centralized administration."

"The scalability of VMAX is somewhat limited, especially in terms of cache scalability."

"The configuration part of the product is an area with certain shortcomings where improvements are required."

"The scalability of VMAX is somewhat limited, especially in terms of cache scalability. We've had to procure additional engines to address this limitation."

"We encountered some challenges during large data migrations that could be addressed for smoother transitions."

Pricing and Cost Advice

"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."

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

"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."

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

"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."

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

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

More Pure FlashArray X NVMe pricing and cost advice

"The Dell EMC Data Protection license covers everything, like a one stop shop. All our options are covered."

"The pricing is reasonable. We're using the Flex on Demand pricing. It's really good for us when we pay for what we use. It made it easy to get it inside since it's an OpEx and instead of CapEx expense."

"Obtaining a warranty is easy."

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

"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.""

"The solution is very expensive."

"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."

"The price of Dell EMC Unity XT is higher compared to other solutions. The price should be less expensive."

More Dell Unity XT pricing and cost advice

"The price falls within the mid-range, neither inexpensive nor high-priced."

"It is not a cheap product."

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."
