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.

Good customer service and support and suitable for large environments

It is very easy to install. Users don't need to remember anything while deploying IntelliFlash because everything will be taken care of by tech support. They can easily modify the installation or change the password with the help of the tech support. It is very easy to integrate IntelliFlash with other solutions. We have plugins that can be integrated with other solutions. It will require maintenance. It is the same as any other storage solution: updates and upgrades, firmware upgrades, and drive upgrades.

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

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

"It has good, reliable, fast storage."

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

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

"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."

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

"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."

"The solution is very straightforward to set up."

More Pure FlashArray X NVMe pros

"Data Compression: Up to 80% space reduction in the database"

"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."

"High performance and ease-of-management are the most valuable features."

"The initial setup is straightforward."

"It performed great originally, and when it performed great, it was awesome."

"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."

"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"

"We use IntelliFlash products for larger environments, like Qatar Airways."

More DDN IntelliFlash pros

"After migration to Unity 300F, we were able to put more DBs on flash, reducing latency. The results were visible in the front-end systems, and all users noticed the improvement."

"It is nice the way ESRS works with remote support, being able to remote in and take a look at problems proactively."

"The performance is great. We have four or five different Unity arrays, and they have all run flawlessly."

"The ease of management and “user-friendly” management environment (GUI)."

"Real Unified Storage (Block, File, VVols) in a unique 2U hardware."

"There are also DR and data protection functions that we found in the new Unity, now that we are stepping up from VNX and other storage appliances, that we've started implementing."

"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."

"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."

More Dell Unity XT pros

Cons

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

"We need better data deduplication."

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

"We would like to see more visibility into garbage collection and CPU performance in the GUI."

"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."

"One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them."

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

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

More Pure FlashArray X NVMe cons

"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."

"It only keeps one hour of real-time data without the ability to do deep analysis of each element."

"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."

"In future releases, I look forward to more AI features."

"In the proxy section you can’t choose a user account and password, so it is not allowed at the moment to go out, if customer has such constellation."

"We had just one small stability problem with power flapping and it did not start up again automatically. We had to access service ports and manually restart the storage processors."

"It's somewhat scalable, but maybe not so much as some of the competition."

"Performance is horrible now. Our original intent was to buy new storage in about two years. But since it became a critical urgency for us, we decided to purchase a new one in two or three months."

More DDN IntelliFlash cons

"The uses of tools to communicate with EMC directly. With EMC, I am not able to connect and resolve issues without assistance, so they can't do unattended maintenance on devices, which would be a massive benefit if they could."

"We would like an AI feature that would protect the backup and minimize the consumed space so we can maintain the quality of the backup. This would help us minimize our IT cost in terms of the backup procedures."

"Data replication needs improvement as the future roadmap for RecoverPoint appliance is not there."

"I would like better integration with RecoverPoint. My major issue with the solution, all around, has been RecoverPoint more than Unity. While I like the easy user interface, I would like some more advanced features for troubleshooting built into the product, so that we can do more in-depth problem-solving."

"In the dashboard there could be notification of duplicate files and the like, so we don't have to rely on Windows to do that."

"It is expensive, and the pricing could be better."

"There is no de-duplication. Unity used to be Bionics, which had de-duplication; however, in Dell Unity XT, the de-duplication was deprecated and is no longer available."

"One of the issues we've had is that controllers have crashed several times... We've had a lot of problems with the storage processor, SPBs. We've actually had them crash."

More Dell Unity XT cons

Pricing and Cost Advice

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

"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."

"The product is expensive."

"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."

"Pure FlashArray X NVMe’s pricing is cheaper than other products."

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

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

More Pure FlashArray X NVMe pricing and cost advice

"I recommend the full bundle software in order to have all the functionality. It is more expensive to purchase it one by one."

"I think we pay around 100 grand per year for three arrays or four arrays."

"The solution should be cheaper."

"The solution’s pricing is competitive."

"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."

"It's the performance combined with the gig-per-dollar value. That combination is superior to other storage options."

"The solution is very expensive."

"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."

"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 is shipped with all licensed, included for this product range, no need to buy additional licenses"

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."
