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 very straightforward to set up."
"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."
"Overall stability is very good. It is a very stable solution."
"Technical support has been helpful and responsive."
"The most valuable feature of this solution is its ease of use."
"One of the best features is the support, which is excellent."
"The solution is scalable."
"It has good, reliable, fast storage."
"The PowerMax software and CloudIQ let us get an inside view of our compression and compaction, as well as our usage of the storage."
"The response time, compared to XtremIO, is far better."
"The number one most valuable feature is reliability. I want to go home at the end of the day and come in the next day knowing it works, especially since we have storage offshore."
"The solution's snapshot capabilities and replication are very good features. Snapshots are allowing us to quickly build analytical models directly from production data. This gives us amazing insights into market trends and allows us to build more effective trading algorithms. Replication offers us unparalleled levels of resilience."
"The compression and deduplication are always on. We get more than 4:1 capacity savings using them. The efficiency benefits from compression and deduplication are through a specialized hardware module within the storage itself, and that means there is no overhead to the compression and dedupe."
"The most valuable feature is the performance and compression. The most useful tool is CloudIQ."
"PowerMax is a compact high-performance appliance. It is one of the best devices in terms of performance specs. It includes an NVMe All-Flash Array."
"The UI is very easy to use. We can add volumes and manage them easily."
"All-flash array eliminates all the overhead of tiering and a lot of the data structuring overhead involved."
"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."
"It is a workhorse and will run even demanding workloads."
"We have resolved IT challenges with this solution. It sped up our environment. We went from spinning disk to all-flash, which reduced our footprint."
"It is simple to use and easy to manage. We don't touch it after we set it up."
"The product has helpful local technical support."
"On the Data Domain side, the most attractive feature is the compression ratio, which none of the other products in the market are currently able to provide. On the Unity side, what customers mostly like is the availability guarantee."
"The most valuable feature is the integration with vCenter."
"We need better data deduplication."
"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."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"The tool's portfolio is minimal. It is expensive."
"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."
"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."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"In terms of what needs improvement, the dashboard and management could be simplified."
"I believe it would be of great benefit to work on the customization of the pricing structure for different enterprises and their specific needs."
"There is some room to grow, especially with some of the installation quirks."
"They should work with the storage engineers to better tweak the management tools to give them improved visibility into their data."
"I would also like to see a real-time, graphical view of metrics. I don't know how far back in time we can look, but if we could see the performance from two months or three months back, and how it is performing now, that would be helpful."
"Although they call it unified storage where you have SAN and NAS, with a NAS implementation on top of a SAN, the NAS implementation is a little complicated and clumsy. As SAN, as block storage, it is very powerful... If they could provide a very good NAS implementation, it would be better, so that customers don't have to look for other simple solutions for NAS."
"There are some stability issues that we just recently experienced. We hope the next release will solve these problems."
"Support of the product can be slow and an administrative challenge: planning, scheduling, and overseeing data center access for a Dell EMC rep. One improvement could be to enable a self-maintenance option. The requirements that we go through to get Dell EMC onsite to replace failed drives, power supplies, and other small redundant parts can be unnecessarily complex. If simplified, they could send us the parts, then we could replace them much faster, more easily, and truly within the SLA parameters."
"The NVMe integration could be improved."
"Ordering is easy, but the processing site and working with those companies was difficult."
"Problems with I/O modules, with bugs that came out that really should have been caught before the product was released."
"It needs deduplication. We'd like to have the dedupe capabilities in the Unity."
"You can't use every feature, because it costs in performance. Therefore, you have to choose which features to use to achieve a better environment. That is why customers do not use every feature in Unity."
"If you compare it with VMAX, where we communicate with the box through Solutions Enabler and there are a lot of commands and a lot of flexibility, the command line for Unity needs to enhanced."
"This is a tier-three solution and it gives us what we need for archiving and backups."
"There is room for improvement in manufacturing."
"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."

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?
