We performed a comparison between Dell Unity XT and Dell PowerMax NVMe based on our users’ reviews in four categories. After reading all of the collected data, you can find our conclusion below.
Comparison Results: Based on the comparison parameters, Dell Unity XT came out ahead of Dell PowerMax NVMe. Although the two products have similar pricing, support quality, and ROI, users found Dell PowerMax NVMe more difficult to deploy and with fewer valuable features.
"One of the best features is the support, which is excellent."
"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."
"It has good, reliable, fast storage."
"Technical support has been helpful and responsive."
"The most valuable features of this solution are its ease of use and performance."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"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 initial setup was extremely simple and straightforward."
"It significantly simplifies storage."
"There is no management overhead involved in optimizing performance. It does it so well on its own. We don't have to manage much at all. It really is like a set it and forget it solution. My storage engineers love the system. It is a lot less work than our previous systems, which weren't bad by any means. There is not nearly as much management as before. So, we are saving dozens of hours per month for our storage team, and that is a real cost in our business."
"My storage engineers are very happy with PowerMax. They are very pleased with the performance, decreased latency, and dependability. From the team, the RESTful API makes management so much easier for them versus the command line interface."
"Key features include performance, replication time, and dedup and compression."
"PowerMax, with version 9.02, which we installed recently, has some very good features, such as CloudIQ."
"You can use PowerMax for all workloads and consolidation. We have used it to scale thousands of VMs."
"It is a true, stable product."
"The SRDF replication piece is probably the best feature. It's useful for maintaining recoverability in the event of a disaster."
"The product has helpful local technical support."
"Setup is simple."
"Integration; We use the product with VMware, and also use it with Syft for home directory and departmental shares."
"The UI itself is fantastic, and the ease of administration is far better than Unisphere or Navisphere ever were. It's very easy to manage. The fact that it has built-in APIs means our automation people can help us automate a lot of tasks, and that has been helpful. And, of course, it's really fast. Obviously, that doesn't hurt anything at all."
"One of the things that I like the most about it is how they have changed the Unisphere GUI, and how it is now HTML5. It is so easy to use. Also, the array itself is so simple, easy to set up and easy to use, but it still has that great Dell EMC technology behind it."
"A lot of the Unisphere interfaces are greatly improved in terms of monitoring capabilities, alerting, and ease of use. Setting up the storage and the file system are all just a few clicks away."
"It's an all-flash Unity, With that compression feature, it's comparable to a hybrid. That is one thing that we definitely like."
"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."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"In terms of what needs improvement, the dashboard and management could be simplified."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"The software layer has to improve."
"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."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"The tool's pricing is higher than competitors."
"The tool is costly compared to other similar products. The product's pricing needs to be improved. I would like the product to include the replication feature in its future releases."
"I think management is where PowerMax is weakest. We're still managing it like we managed EMC arrays in the early 2000s. There's a slicker, fancier GUI that does more things, but at the end of the day, you still have to dig into the command line and issue a lot of the same commands that we still were using almost 20 years ago."
"I would like them to continue improving the management tools and continue moving towards a RESTful API versus CLI."
"I would like the scalability to improve, as it requires additional footprints."
"Since the merging of EMC and Dell into Dell Technologies, there has been a hurdle that they've had to overcome, and they're not over it yet. It takes two to three times longer for things to get fixed than it did when they were separate companies. That is something that has to be fixed."
"When it comes to Oracle and database workloads, data reduction could be a little bit better. Some of the competition, like Pure, have post-processes which do additional deduplication and compression on the backside; everything is in-line and then they do a secondary process. It would be a good option if you could start getting 5:1 or 6:1 data reduction on database workloads."
"I would like a more informative CloudIQ for iOS. What you can see via the web UI significantly differs from what you can see via the web application."
"The solution does not use new versions of OS and patches. Its installation is also difficult. The solution is not as fast as other storage in the market."
"There are features still to come, like compression and deduplication on hybrid platforms, VDM improvements to be developed for NAS environments, and also improvements in the “self-migration” tools to push or pool information (to assist the migrations to and mostly from third-party arrays)."
"In terms of what could be improved, I would say its capacity and its connection."
"The support portal needs fixing. Accessing a service request on the support portal seems to be a bit difficult, as opposed to just calling the 800 number."
"This is a tier-three solution and it gives us what we need for archiving and backups."
"The reporting should be better. In other systems, you can create many different kinds of reports but this is not the case with Dell."
"Having more artificial intelligence tools built into the solution would be a great benefit. This would allow us to see more about the workloads and higher visibility, such as performance degradation."
"I would like to see more integration with other products."
"There's always room for improvement with the UI. That can be a little cumbersome at times."

I have used all, EMC, and HPE 3Par, VNX, Unity, etc. All are OK. But for long term Flash Storage, I would take a look at Hitachi F Series. Best reliability hands down and they provide non-disruptive migrations, no server downtime, no scheduling with users, etc. NDM makes Hitachi a no brainer.
Many insightful answers already provided.
I would just add the following based on my experience. With so many employees an located in different places, its important for you to list the issues being encountered with the present setup, in addition of the need to upgrade, of course :
- Latency -if being experienced generally or specifically to a location as this may indicate a network issue and this is better solved before the upgrade to new storage in order not to disappoint users
-Type of need : analytics/ Big data, classical operational transactions, archiving - in this case you may go for Tiering ( that is have NVMe as the top Tier and SSD as Tier 2). Users are normally demanding but given the costs in a time of budgetary cuts, better offer them different Tiers with front end ones data residing on the better Tier
- Finally, also make sure you have some well structured storage network as you don't want some big fat slow Database VMs located in one of your data centers impacting on the performance of your leaner VMs provisioned on NVMe.
Hello Robert,
What you need to know is in the world of storage infrastructure all the constructor offers a portfolio group by categories like Entry Level Storage, Midrange Storage, Enterprise storage
PowerMax is an enterprise storage on the DELL EMC portfolio
Enterprise storage is usually used for Mission critical Application where the availability required is 99,9999%. With enterprise storage you can manage approximatively 15Millions of IOPS which are very important when you want to take decision to consolidation storage.
Personally, if you cannot expect to reach Millions of IOPS I recommend to go to DELL EMC Unity XT, otherwise move forward to Power Max
PowerMax offer many features like SLO for categories of Application (Diamond, Gold, Silver)
Diamond latency < 1ms
Gold Latency >1ms
Silver Latency >10ms, <20ms
You have also FastVP to move Hot Data to the fastest TIER storage
Physically PowerMax use a Virtual matrix to interconnect all the Engine which can reach 8 depending of the model
Midrange storage use only two controller and provide you and availability of 99,999%
Unity XT is better than HPE MSA or 3PAR
If you want other informations you can contact me
Does PowerMax have storage virtualization for external storage as part of the package?
