Here are some excerpts of what they said:
Pros
"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 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.""We removed the need to observe whether we ran into issues with the performance of disks or number of IOPS. Previously, our Oracle Database would throw us performance errors. Now, with PowerMax, everything runs smoothly.""You can use PowerMax for all workloads and consolidation. We have used it to scale thousands of VMs.""It allows us to protect our data using different data centers and replicate bi-directionally between our two main data centers.""Technical support has been excellent.""The performance is very good. Our predominant workloads are all less than 5 milliseconds and it's most common to have a sub-1-millisecond response time for our applications. In terms of efficiency, we've turned on compression and we're able to get as high as two-to-one compression on our workloads, on average.""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."

"My storage team likes Unity's replication features. Three-site replication is a unique feature that EMC offers us.""The inline deduplication and data reduction capabilities have been the most valuable.""The most valuable feature is the dynamic cache of this product. It is very important. We have the physical cache and we can boost this cache using disks. All the products are mainly flash now and this is one of the main characteristics which our customers like.""When I have an issue and need technical support, I reach out to them either through chat or by submitting a service request, and the response is good.""The most valuable features are its performance and simplicity.""Dell EMC Unity XT has good integration with VMware.""The most valuable feature is the fast cache with functionality rewrite.""The complete block and file sharing are the most usable features."

Cons
"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.""I would like to see more development in the cloud environment. It would be good if it comes in the cloud kind of setup.""PowerMax Storage needs improvement in the area of monitoring tools. It should have more functions and more complicated analysis options inside the monitoring tools.""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.""Some of the management features could be simplified and that's probably the main thing they need to address.""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 GUI interface is very complicated and could be improved by streamlining the number of steps in the process.""We have had some trouble with the VMAX-to-PowerMax migration, but the VMAX box will be powered down after the migration. The PowerMax boxes are working fine and we don't have any issues with them."

More Dell PowerMax NVMe Cons →

"The pre-sales technical support and technical engagement could be made better for this product.""It could go faster. Make it bigger, better, and faster at a lower price, and I am there.""Issues with slow responses from the support team.""We do a lot of VMware. It only integrates with VMware in one way, which is virtual volumes. I don't really have any visibility on anything else. From VMware, I can't look into Unity. From Unity, I can't look into VMware unless I am using virtual volumes, where they integrate together happily, but we are not using that. I would like better integration for non-virtual volume VMware use.""Support Responsiveness & time to fix bugs should be improved.""In terms of what could be improved, I would say its capacity and its connection.""The initial installation is straightforward and took approximately one hour. However, the full process was not as simple as IBM.""Dell EMC Unity XT should present a path or a roadmap on how they could put their products on the cloud. This would have some value for their current customers."

Pricing and Cost Advice
  • "Negotiate hard and consider the commercial advantages/benefits to Dell EMC for onboarding your product."
  • "One area for improvement, one that everybody always comes to, is price... it's still quite expensive to purchase these big arrays... For us, the pricing doesn't make Dell EMC uncompetitive."
  • "In terms of price-performance, it beat out other competitors when we were taking a look and comparing it to the market. That was one of the biggest driving points for us."
  • "The labor savings and support have been significant. If we're talking 100 hours of labor every three months, that is 100 hours of a database engineer costs. There are performance latency numbers as well as costs associated with recovering data that gets lost, and this system doesn't lose data. You can look at numbers that go around the cost of downtime, if data is not available. This system doesn't go down. Everyone's ROI is going to be unique, but the dependability and performance of the system combined with its ease of operation will definitely save businesses of all sizes money."
  • "Its price is competitive, but they need to have a different price for West Africa. They can do better with the price point to allow us to scale even more. We wanted to migrate our entire storage infrastructure to PowerMax, which would require us to buy more capacity, and from the price point, it didn't attract us."
  • "The PowerMax appliance pricing was reasonable. Dell EMC quoted us a substantial discount."
  • "Support pricing is very high. Our support contract is about to expire and Dell EMC provided us with an extremely high renewal quote. It was four times more than the support contract for our previous EMC VNX solution."
  • "It is high-end storage and it is a bit expensive, but it is doing what it is meant for: running business-critical applications or latency-sensitive applications..."

  • "The price of Dell EMC Unity XT is higher compared to other solutions. The price should be less expensive."
  • "Pricing for this product is manageable, though slightly higher than comparable products."
  • "The solution is very expensive."
  • "The solution is very expensive."
  • "This solution is a good price for what you get."
  • "Here is our major complaint with pricing. Dell EMC comes to us and gives us a price. We are like, "Well, this doesn't even compare to what we got on the last project." We say, "No, you should bring it down to this level." Then, they come back again and we are sort of in the middle again. I am like, You already sold us other stuff at a better price. We are not going to just say, 'Yes,' because we are out of time.""
  • "I liked the price point when we purchased it."
  • "We looked at HPE Nimble but the price of the Unity XT was very good compared to the competition."

    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

    Reviews from Real Users

    Below are some reviews and helpful feedback written by Dell EMC Unity XT users.

    A Systems Engineering Manager at a manufacturing company says, "It is definitely one of the most robust, solid, well-performing products that I have dealt with. It is set it and forget it, which is pretty amazing." He also mentions, “We can do both block and file storage on one unit without purchasing a separate device.”

    Peter S., Senior Technical Specialist at a healthcare company, states, “The most valuable feature is reliability. At the end of the day, it just runs. This solution is easy to work with and easy to maintain.”

    PeerSpot user Melvin T., Senior Systems Engineer at Prosperity Bank, explains that the solution is “easy to use and we can add LUNs or space without interruption to end-users. We're able to access it from just about anywhere, as long as we have access to a browser. That feature is really neat because sometimes we will go to a different data center or a different site, and if we need to access it to see a LUN or to see any type of storage, we can do that. That's one of the big takeaways with Unity."
