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 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 most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."
"Technical support has been helpful and responsive."
"The solution is very straightforward to set up."
"The most valuable feature of this solution is its ease of use."
"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."
"Overall stability is very good. It is a very stable solution."
"One of the best features is the support, which is excellent."
"The tool is a fast-performing asset. It can perform millions of transactions within a second. I like the tool's architecture as well."
"It was easy for teams to pick up the technology with very limited exposure and training, then implement and support it."
"It is a very stable solution. I would rate it a ten out of ten."
"It offers a high level of availability, so pretty much near zero downtime."
"It has reduced our footprint in different physical locations."
"We use ESRS for our call-home, and a lot of times, Dell EMC will respond to the issue before we even know it."
"The UI is very easy to use. We can add volumes and manage them easily."
"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 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 is easy to scale, maintain, and manage."
"We have Dell EMC engineers helping us out and doing some over the shoulder training. They are working with our customer right now doing data migration over to Unities from the legacy Oracle stuff. While they're doing this, they're showing people how the Unities work and the ins and outs of the software interface."
"I like that the solution is scalable. The initial setup is not complex. The basic licenses and software are included in the package. he primary advantage is that this product has been thoroughly tested and proven over time. I recommend this product."
"All-flash is a game changer. If you need performance, simple operations, and you plan to use it with VMware, it is a good choice."
"It's easy to manage. We access it and manage it through Unisphere and have had no issues. We're able to provision storage, create consistency groups, create RDMs for our virtual machines. Creating it through Unisphere, it automatically adds the data store on the VMware side and rescans the LUNS. We just have to add and configure the storage in one place and it takes care of everything, which is very handy."
"Via a click, we can deploy a data store or LUN to the ESX host. We can also deploy VVOLs to the ESX server."
"They have a Unity REST API that I use to automate some of the storage stuff. I'm just getting started with it, but it seems pretty easy to use."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"They could add more support for file storage and different types of storage."
"In terms of what needs improvement, the dashboard and management could be simplified."
"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."
"The tool's pricing is higher than competitors."
"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"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."
"There are definitely some improvements that can be made to the CloudIQ."
"We are very interested in NVMe over Fibre Channel, which I understand is on the horizon. We would like to see that come to fruition."
"They should work with the storage engineers to better tweak the management tools to give them improved visibility into their data."
"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."
"PowerMax Storage needs improvement in the area of monitoring tools. It should have more functions and more complicated analysis options inside the monitoring tools."
"The REST API needs improvement. We are a very big automation company, and this would be big for us."
"This is a tier-three solution and it gives us what we need for archiving and backups."
"It would be great if the solution could integrate an NVMe disk."
"Currently, the protocol SNMP is not implemented. That's a problem, as we follow this protocol and I can't check the integrity of this equipment."
"Issues with slow responses from the support team."
"The user interface could use improvement."
"Since Dell took over EMC, the support has been very bad. Before, the support was fine. Now, the support is slow or they don't react."
"Unity only does compression. It would be nice if there was a deduplication feature as well. At my previous job, we used XtremIO and that was deduplication and not compression, and I think we got more out of it because the more OSs you have that are the same, the fewer copies it needs to keep of all that data. So, the deduplication would be a nice feature to have."
"There is room for improvement in manufacturing."

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?
