We asked business professionals to review the solutions they use.
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.""Based on our experience with VMAX, there isn't any hardware failure or something like that in PowerMax. Performance-wise also, everything is fine. We haven't faced any performance issues or any hardware failure. Its performance is great as compared to VMAX. Its I/O per second rate is higher than the old model.""Technical support has been excellent.""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.""You can use PowerMax for all workloads and consolidation. We have used it to scale thousands of VMs.""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.""They're basically tanks. You could take a baseball bat to the thing, and it's still going to keep running and doing what it's supposed to do. We've had a couple of part failures, and you can pretty much replace any part on that thing at any time during the day in the middle of production without worrying about anything happening.""We like the compression, dedupe, and I/O on the PowerMax. They are better than on the XtremIO."

"I have found Dell EMC Unity XT to be stable.""I like how it separates the iSCSI drives from the standard shares. It has two different routes to it. I know most of the other solutions do this, but I just like the way that Dell EMC does it.""The solution allows for easy, useful replication with good features for VPLEX and VIVO.""Dell EMC Unity XT has good integration with VMware.""The most valuable feature of Dell Unity XT is the GUI, it is very good. End users can manage using it. Additionally, the documentation is of high quality and it integrates well.""Stable data storage platform which promotes ease of management through its multi-cloud support. Remote support provided to users to address issues is very good.""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.""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."

More Dell Unity XT Pros →

Cons
"Firmware updates are a bit painful because you have to involve their support, as opposed to having the ability to do it yourself.""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.""Some of the management features could be simplified and that's probably the main thing they need to address.""We would like more documentation, a guide to the features of the PowerMax.""I think management is where PowerMax is weakest. We're still managing it like we managed EMC arrays in the early 2000s. There's a slicker, fancier GUI that does more things, but at the end of the day, you still have to dig into the command line and issue a lot of the same commands that we still were using almost 20 years ago.""The price could be lower, and we are unhappy with the price.""If you go to Pure or you go to NetApp, they deliver in one month. If you go to Dell or HP, they will take up to six months for delivery. This is not a business model for today.""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."

More Dell PowerMax NVMe Cons →

"Dell Unity XT could improve the compatibility of some of the features. Some of my customers had some problems. Additionally, it would be beneficial for the solution to have advanced AI and ML features.""The reporting should be better. In other systems, you can create many different kinds of reports but this is not the case with Dell.""In terms of what could be improved, I would say the deduplication part, because for large deduplications, you need an extra appliance to do it in order to avoid having problems in performance. I think that could be improved, because everything should be included in the product, not with an appliance from the outside.""We have only used this solution for less than one year so I don't have any improvements suggestions yet.""The interface and configuration could improve.""Our request to Dell EMC for improvement was in the reporting and monitoring areas. Dell EMC built up a cloud ID so that we could see the overall storage numbers. We needed to have the proper KPIs to be able to see and manage things.""Dell Unity XT could add a unit-to-unit replication. We haven't seen that because we don't have an additional one to test. However, it is not an improvement, but something that we would like to have visibility on how it's done or how it works.""This solution could be improved by offering containerization. This is something many of my customers are looking for."

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."
  • "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 pricing for this solution is good compared to other products in the market."
  • More Dell PowerMax NVMe Pricing and Cost Advice →

  • "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."
