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.
"The solution is scalable."
"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"The most valuable features of this solution are its ease of use and performance."
"Technical support has been helpful and responsive."
"The most valuable feature of this solution is its ease of use."
"The solution is very straightforward to set up."
"What I really like about this program, is that it is easy to use and easy to configurate."
"It is easy to manage and upgrade."
"We are most interested in cloud utilization."
"The SRDF replication piece is probably the best feature. It's useful for maintaining recoverability in the event of a disaster."
"Uptime by far is the most important thing, and also the replication ability (SRDF). Most of the customers who need this type of availability also want the protection of multiple data centers, and it is able to easily switchover workloads to their other data centers."
"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."
"The smaller footprint of the device has been really nice. We have gone from eight bays to one bay. Having one floor tile in our data center has been pretty awesome. A lot less power and HVAC cooling is being consumed."
"PowerMax, with version 9.02, which we installed recently, has some very good features, such as CloudIQ."
"It has dramatically cut down the footprint in our data center and reduced the amount of raw disk capacity that we needed to purchase."
"The most valuable feature of Dell Unity XT is data duplication. Additionally, the management interface is simple, and is not a hassle using it. You don't need too much to learn or to be familiarized with it."
"The feature that I have found most valuable is the unified storage. Also, its capabilities for block-access, file access, and the center box."
"It is scalable. We can add additional tools if we need to expand it."
"It will certainly help us scale bigger. If I look at the footprint, the VNX's was multi-rack. Now, all of a sudden, we're only at a portion of a rack. And, obviously, if we can scale within the same rack - we can certainly see that by the number of hard drives we've had to put in - we can scale a lot more easily."
"It has compression, which allows you to store more data than you would normally under the arrays."
"We use it to implement all our VDI solutions."
"The setup and installation procedures are easy."
"The most valuable feature is that the solution is a hybrid system, so you can do both block and file storage."
"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."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"The tool's pricing is higher than competitors."
"In the future, I would like to see integration with enterprise backup systems."
"I would like to see replication and DR features in the next release of this solution."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"I believe it would be of great benefit to work on the customization of the pricing structure for different enterprises and their specific needs."
"The tool needs to improve its performance. Today's applications are demanding a response rate of one millisecond or below. The product should also look into AI integration."
"There are some stability issues that we just recently experienced. We hope the next release will solve these problems."
"Dell can improve the Service Level Agreement (SLA) compliance. Sometimes, when we need to replace a component, the SLA says four hours, but for some reason, the technician doesn't arrive until the next business day or even six to eight hours later before the case is placed. So, focusing on respecting the SLA is where Dell could improve."
"It's a relatively new product, but for the next release I would like to see higher bandwidth on the front-end adapters. This would allow even greater scalability for critical workloads and consolidation for non-critical workloads. The hosts may not require that level of I/O performance today. However, it allows us to scale physical non-cloud environments without large investment."
"The initial setup was complex, and we had experienced people working on it."
"I would like to see continued visibility and analytics in the platform."
"We have issues that we don't know about, which Dell EMC fixes."
"More integration with VMware would always be helpful, plugins that go directly into the vSphere management. A single pane of glass is always beneficial."
"Dell could improve Unity XT by adding support for NVMe."
"Stability is the problem. We've had stability issues with it. We've had problems with the iSCSI interface. We've had it for two years now and for two years we've had problems where a service processor will drop, we'll lose connectivity to LUNs, we'll lose connectivity to the storage, issues like that. No matter how we've tried to chase it down, everybody just points fingers at each other. The only thing that changed in our environment was that the Unity solution was installed."
"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."
"It should be lighter. It takes up a ton of rack space. It would be nice to have a smaller footprint."
"The user interface could use improvement."
"Dell EMC Unity's competitor, NetApp, has a similar product. However, it has a clustering technology where you can group multiple systems together, then you can move data from one system to another seamlessly. I would like the Unity to do that."
"The upgrade process needs improvement. I should be able to swap it out, with zero downtime, with another array, down the road. I don't think Dell EMC has anything in the roadmap for this product line. I just don't want to have to deal with that anymore and all of our customers are pretty much the same."

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?
