Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"The most valuable feature is the integration with vCenter.""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.""The most valuable aspects of this solution are its stability, performance, and ease of updating.""The complete block and file sharing are the most usable features.""The most valuable feature is the fast cache with functionality rewrite.""I have had no problem at all. I think this is one of the most important things. It is very good. Maintaining it and deploying updates require very low maintenance. We haven't had problems. We had to replace a couple of disks in all these years, but it was pretty straightforward.""This solution is easy to work with and easy to maintain.""My storage team likes Unity's replication features. Three-site replication is a unique feature that EMC offers us."

"Good performance with a user-friendly UI.""A key feature is that compared to storage systems that we've been familiar with over decades, IBM simply does not fail. The reason is that IBM is the only manufacturer that engineers its own flash module, and there is a key architectural difference from everything else that we have seen in the market. The difference is that the flash module has the computational capability, which allows reliability and capacity enhancements to be uploaded from the main controllers and run in each module. So, each of the flash drives becomes its own little storage system, and that is extremely effective architecture. In this field, with this type of system, IBM has made a statement. They've never had one of these modules cause an outage. So, the failure rates on these things are just in a whole different universe from what we were accustomed to."

Cons
"One area of improvement is replication. We are also using Oracle virtual machines, and when you are using systems from other vendors, the process of replicating from Unity through OLVM is more laborious than when we were using VPLEX.""I would like it to be a little bit easier to contact support. We can contact support, but we have to go through a phone tree. We get routed to different places. I might call support to say that I need a drive replaced and get transferred to three different groups before I get to the group I actually need.""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.""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.""The solution should include a free process in the HPE portal that uses serial numbers to verify that hardware is genuine.""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.""We have only used this solution for less than one year so I don't have any improvements suggestions yet.""I think Dell EMC should be more careful in appointing partners, and they need to have better control over their partners. And if their partner has some problems with them, we should not suffer."

More Dell Unity XT Cons →

"I'd like to be able to connect to tape drives behind the storage device to back up the tape if need be. We have all of our storage running in all-flash, and we make a copy on tape. Currently, when we want to hook up tape drives, we have to add some extra equipment, which is a little bit complex. We want IBM to add a feature where we could install a tape into the storage so that we can connect it through a single pane of glass. We'd like to have a feature in the IBM flash storage system so that we can connect backup tape drives through the IBM storage system and we can manage the backup tape from the storage system.""Deduplication and compression should be improved."

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."
  • More Dell Unity XT Pricing and Cost Advice →

  • "It's a lot less costly than cloud storage. People get surprised by the cost of cloud storage, which is extremely expensive and four or five times the cost of storage on-premises. People don't realize what they're spending on storage until they start getting bills from Amazon, Microsoft, and others. This is a good way to reduce your cloud storage expenses."

    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."

    IBM FlashSystem 9100 combines the performance of flash and Non-Volatile Memory Express (NVMe) end-to-end with the reliability and innovation of IBM FlashCore technology and the rich features of IBM Spectrum Virtualize - all in a powerful 2U enterprise-class storage system. Providing intensive data driven multicloud storage capacity, FlashSystem 9100 is deeply integrated with the software defined capabilities of IBM Spectrum Storage allowing you to easily add in the multicloud solutions that best support your business.
