Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"We have been able to consolidate storage into Pavilion. Pavilions are our only SANs because it is a bring your own disk solution. When new drives come out, we are able to take out half of the drives in the system, put in new drives, move our VMs over to the new drives, take the other drives out, and populate those with new drives. Then, we are suddenly twice as dense as we were before. NVMe flash is only going to get denser and cheaper so we can make use of that every couple of years by just throwing newer disks into it at a fraction of the cost of a new SAN.""The high performance is very valuable, as well as the enterprise reliability features.""There's lots of flexibility in how we use the resources while also maintaining a small footprint."

"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.""Stable flash storage platform with good scalability, efficiency, and speed.""This is a tier three solution and it gives us what we need for archiving and backups.""I have found Dell EMC Unity XT to be stable.""Initial setup is a simple process.""The most valuable features include snapshots, Thin Clones, and deduplication and compression.""The setup and installation procedures are easy.""We are happy with the way we have Dell EMC Unity XT configured."

More Dell Unity XT Pros →

"Last year, I did a DM Series installation with my colleague, and this installation was effortless because we had Lenovo support on the phone, so it was easy to get help if we had any problems.""Scalable and stable storage array.""Ability to cluster two storages together with HA availability.""The solution offers very good reliable systems and storage for our clients.""The price of this solution is good."

Cons
"The rail system that Pavilion uses to mount up into a standard Dell or APC cabinet extends further back than normal rails, and they cover up the zero PDU slot. So, I don't like the rail system that comes with the device. That is my biggest complaint.""In our current configuration, we can only run the line controllers in high availability, active-standby mode, whereas we would like to see active-active implemented.""I would like to see the management layer improved."

More Pavilion HyperParallel Flash Array Cons →

"It could be improved in the area of management flexibility. For example, I really need to set read-only access for LUNs, and there's no such option with Unity XT.""In terms of what could be improved, I would say its capacity and its connection.""Having more artificial intelligence tools built into the solution would be a great benefit. This would allow us to see more about the workloads and higher visibility, such as performance degradation.""They can certainly improve in terms of monitoring.""I have a problem because between the Unity XT and the PowerMax, sometimes we need another product between these two products. There could be better integrated and the capacity of the size could be larger.""This solution could be improved by offering containerization. This is something many of my customers are looking for.""The pre-sales technical support and technical engagement could be made better for this product.""Dell could improve Unity XT by adding support for NVMe."

More Dell Unity XT Cons →

"This is an expensive solution.""I would like Lenovo to add a feature like IBM Easy Tier to DM Series. This is a crucial feature for the customers.""The licensing model needs to be revisited. It needs to be simplified.""Many people do not realize that Lenovo has a storage solution, so better marketing from the vendor is needed.""The Lenovo ThinkSystem DM Series was very hard to configure. Installation of the product was very hard. These are its areas for improvement."

Pricing and Cost Advice
  • "This is hardware. They have a singular array that you can populate with your own disk, or you can buy the disks through them. For controllers, you pay for the components inside of the SAN, but there is only one chassis that they work with."
  • "The licensing fees are very reasonable."
  • More Pavilion HyperParallel Flash Array 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 →

  • "Lenovo offers two software tiers for the DM Series: basic and premium. If you need more features like the MetroCluster, you must buy the premium version. You can stick to the basic software if you don't need MetroCluster or features like asynchronous replication. That makes DM Series a little cheaper."

    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."

    To meet enterprise storage requirements, ThinkSystem All-Flash DM Series systems provide high performance, superior flexibility, and best-in-class data management. DM Series runs on ONTAP data management software, which gives customers unified storage across block-and-file workloads.
