Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"We are happy with the way we have Dell EMC Unity XT configured.""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.""I have found Dell EMC Unity XT to be stable.""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.""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.""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.""The most valuable aspects of this solution are its stability, performance, and ease of updating.""The most valuable feature is the integration with vCenter."

"We've found the solution to be very stable so far.""The performance is very good and we use this product to enhance our core system.""The initial setup is straightforward and can be done in an hour and a half by one person.""The installation is nice and easy.""The most valuable features of IBM FlashSystem are performance and security.""IBM FlashSystem is a powerful effective storage solution. Additionally, it is user-friendly, anyone can use it.""The compression and deduplication features are the most valuable.""Most of the features for the reduction in data compression are useful. It is also very easy to use and administer. Its performance is also good."

More IBM FlashSystem Pros →

Cons
"We have only used this solution for less than one year so I don't have any improvements suggestions yet.""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.""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.""It could go faster. Make it bigger, better, and faster at a lower price, and I am there.""The pre-sales technical support and technical engagement could be made better for this product.""The price of Dell Unity XT could improve.""Dell could improve Unity XT by adding support for NVMe.""It could be a little easier to attach it to a network file system."

More Dell Unity XT Cons →

"The product needs to improve their scalability.""The customer's expectations are what they get on the cloud, they're expecting even in the on-premises deployments, going forward.""The GUI for monitoring performance metrics could provide better visibility. For example, it doesn't let me segregate the IOPS per volume.""The pricing needs to be more competitive.""It could be easier to implement.""The design is a little old-fashioned and could be updated. The rack is very primitive and designed in an older style.""The installation is not easy. You need to have extensive knowledge to handle it.""The support could improve by allowing you to speak to someone when you call rather than them calling you back. However, once we do have contact with one of their technicians they are excellent."

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 →

  • "The integration is already included in the license cost of IBM FlashSystem. The integration is very easy. You get the IBM storage core with all software, firmware, and upgrades. EMC provides the features in the box, but they are not free for customers. There is a licensing cost for features. We have yearly licensing, but IBM has also provided a new option where you pay as you go. They provide a big box, and I pay, for example, for 10 terabytes. If I exceed 10 terabytes, IBM will charge for the new storage after 10 terabytes. It is a good opportunity in the market for using the storage as a cloud and paying as you go."
  • "They've been much more aggressive in the last five, six years than they were before that."
  • "This is an expensive product and if the price were reduced it would be better."
  • "Among IBM, Dell EMC, and Pure Storage, IBM is the cheapest. The price is also based on our location, the size of our entity, and our regular annual purchases from them. We are a very big IBM customer, so we normally get very high discounts. We are not a big customer of Pure Storage. We don't buy that much from Pure Storage per year. Everything is included in the price. There is no extra license for different functions."
  • "Its price is very good."
  • "I find the pricing of the solution to be very reasonable."
  • "You purchase it as a bundle and the price is comparable."
  • "The solution requires a license and could be less expensive."

    As with any engineered solution, it depends on your needs.  


    However, the bottom line is that for their target markets Dell EMC Unity will generally have a better price at parity performance over IBM's FlashSystem.  


    Both are focused on All-Flash arrays and Dell EMC Unity is where I start with VMWare. If I have a dedicated IBM DB2 application, I would lean toward the IBM FlashSystem. 


    The problem in the VMWare environment is that IBM has done a poor job prioritizing this area and has several I/O bottlenecks and interface driver issues. I expect future resolution, but does that happen before current platforms evolve?

    Depends what you're expecting. Full compatibility with VMware environment - DellEMC only, IBM FS has problems with iSCSI connections to vsphere 7.02 - it's not supported (FS5200 and vsphere 7.02 server with Intel cards - doesn't work fast (10Gbe - 300MB/s instead of 1,1-1,2 GB/s), no solution for now from IBM and VMware (08/2021). Integration - DellEMC and VMware are one company - everything goes smoothly. Space reclamation didn't work well on IBM systems when connected to vsphere (vsphere 6.5 and V7000 models). When using Microsoft virtualization - no difference - it's more complex to start system but when properly configured - it runs well (fast). But of both of them I would choose HPE systems,:-) (Nimble or Primera):-)

    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 products are enterprise computer data storage systems that store data on flash memory chips. Unlike storage systems that use standard solid-state drives, IBM FlashSystem products incorporate custom hardware based on technology from the 2012 acquisition of Texas Memory Systems. This hardware provides performance, reliability, and efficiency benefits versus competitive offerings.
