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.
"It gives us capacity planning."
"Pure Storage FlashArray's overall speed is its most valuable feature."
"The solution is easy to scale. I'm running two environments right now, so I need to scale. I'm running a part technology. I've got an A-side and a B-side."
"Performance is the most valuable feature."
"The solution offers amazing performance."
"The scalability options are very nice because you can scale it much better and faster. The scalability was there in the previous environment also, but this is far better than what we had before. It basically helps the user in case they are looking for more storage. We can scale it much faster."
"The GUI is very easy to use and intuitive."
"Most of the problems that we had in the past with the performance in IOPS have disappeared. It has been a great improvement for our customers' services."
"Dell PowerMax NVMe's tech support is good."
"It was easy for teams to pick up the technology with very limited exposure and training, then implement and support it."
"The speed and the compatible interface with IBM are the most valuable features of the PowerMax product."
"We find the service level option to provision storage very valuable. The ability to define different service levels for storage groups helps us in prioritizing our workload at the infrastructure level."
"The stability is great. It is five nines."
"This platform is reliable in supporting our data availability. We now have a higher performing platform and have been able to consolidate our workloads into one single platform."
"The solution has good operability and easy scalability."
"We're consolidating two to three arrays down to one which means that our data center footprint has decreased by like 90%. So we're saving 90% of our space, and it also is much better on power and everything else in our data center. And on top of that, the performance is much, much better than our older arrays."
"It is a workhorse and will run even demanding workloads."
"The product has helpful local technical support."
"The most valuable aspects of this solution are its stability, performance, and ease of updating."
"The most valuable feature is the fast cache with functionality rewrite."
"It is easy to manage overall. It is all web-based. It has a an easy, nice dashboard. I receive emails if there are issues. When there are any updates, I receive emails. I can either do them on my own, but normally I schedule them with Dell EMC and they remote in, then it's done."
"The benefits are the simplicity, flexibility and the ease of integration between the Unity platform and VMware, for example, and Microsoft platforms; the integration tools and the simplicity of management."
"We like the way it integrates with our environment. These features help us use multiple soft applications. The new features of going off the grid and replicating really help us. They give us an advantage versus traditional storage resources."
"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."
"I would rate this solution an eight. There's always room for improvement, nobody is perfect to get a ten out of ten. They do what they do well. It's not cheap but we it's for uses that we needed."
"I would like to see support for NVMe, end-to-end."
"One thing I'd like to see in a future release is integration between their main storage array and what they call their FlashBlade product; to be able to snapshot directly from the primary array into multiple different backup copies on FlashBlade."
"Pure Storage FlashArray could improve the recent file storage capabilities because it is lacking a lot of features."
"The setup needs to be improved the most. They can do a little more with the user interface, but the setup is what I would like to see made a bit easier."
"We would like to integrate it more with our backup solutions."
"I would rate this solution an eight because we have had outages. The commit times went very high in the database. The whole array went down so our customers were down for around eight hours. This was a very big outage which could have been our fault because we didn't do the upgrade in time."
"Self-backup is the only feature lacking in this solution."
"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."
"The technical support is lacking. We are working with Dell EMC to get some better understanding of this."
"Firmware updates are a bit painful because you have to involve their support, as opposed to having the ability to do it yourself."
"Dell should work on their marketing strategies to make the product more visible on the market. They should promote the product's compatibility with IBM, as not everyone knows it."
"I would like the scalability to improve, as it requires additional footprints."
"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."
"Dell PowerMax NVMe is costly compared to other solutions."
"There is also room for improvement in the PowerMax architecture and hardware itself. They should design the PowerMax on the basis of PCIe 4.0. I would like to see the possibility of an NVMe drive that operates on PCIe 4.0 and not PCIe 3.0."
"I think that they could do a better job of testing on the back-end, for the code revisions. I've heard of some issues down the line where people have upgraded to the latest code and there were bugs in it, and they had to release a subsequent code fix."
"The pricing is a bit high. We'd like it to come down."
"We've also encountered an issue when it comes to migrating to compressed LANs on the Unity, and during the Storage vMotion. It appears that the compression algorithm is overwhelmed, and when it becomes overwhelmed it just stops compressing and writes the raw data to the destination. We later copied internally another Storage vMotion to another compressed LAN and achieved much higher compressions on that internal copy. It would be really nice if there was a way to automatically throttle, as a part of a Storage vMotion, to say, "I want to gain the maximum benefits from the compression algorithm, so throttle back the Storage vMotion to implement 100 percent compression.""
"It would be nice to have been able to easily move off our old VNX system to this system. The process is very manual."
"I would like better monitoring capabilities: more historical data with more insight into the performance for the database. We now use a separate tool for it. Therefore, it would be nice if we could have that straight from the tool."
"It is missing some features, like deduplication."
"I don't know where the hybrid cloud might be going or what connectivity there is between what was recently released as far as AWS and being able to manage both of them. Maybe there is an on-prem and an AWS instance in the same window, like a single pane, but I would like to see something along those lines, where there wouldn't be two locations to manage storage."
"Issues with slow responses from the support team."

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?
