We performed a comparison between Dell Unity XT and Lenovo ThinkSystem DE Series based on real PeerSpot user reviews.
Find out in this report how the two All-Flash Storage solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."The most valuable feature is replication."
"The reliability is very good."
"I never have to worry about its performance or if it is the root cause of an issue."
"It allows engineers to focus on other things rather than doing the more manual tasks. It automates tasks, so the ease of use is extreme. It simplifies the storage."
"It's reduced our overhead management time on storage, since it is so simple to get in and just provision a volume, present it to the host, and then you are done."
"It's just very easy for general block storage."
"I like the speed, and I like the API and how programmable it is."
"It's actually very stable"
"One of the things that I like the most about it is how they have changed the Unisphere GUI, and how it is now HTML5. It is so easy to use. Also, the array itself is so simple, easy to set up and easy to use, but it still has that great Dell EMC technology behind it."
"It is easy to set up the solution."
"On the Data Domain side, the most attractive feature is the compression ratio, which none of the other products in the market are currently able to provide. On the Unity side, what customers mostly like is the availability guarantee."
"We run about 100 virtual servers on it. We have about 100 users accessing the file shares from there, and I've seen no problem with that. We have about a 10GB backbone. Whatever we throw at it, it hasn't shown any sign of weakness or anything. It's been really good."
"With all-flash it should be able to scale. You probably just need one 4U device and you have terabytes of space."
"It's very reliable. I have not had an issue with Dell EMC Unity."
"Stable flash storage platform with good scalability, efficiency, and speed."
"It's an all-flash Unity, With that compression feature, it's comparable to a hybrid. That is one thing that we definitely like."
"Lenovo ThinkSystem DE Series is simple to use"
"The solution is very easy to set up."
"Lenovo ThinkSystem DE Series is quite an elementary box, no frills. It does not have all the functionality of the DM but it is acceptable, it does its task. It integrates pretty well."
"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions. It's also easy to use."
"The most valuable features of the Lenovo ThinkSystem DE Series are the dual controllers, available installation documentation, and the option of multiple host bus adapter interfaces."
"The solution's initial setup process is easy."
"The solution is very easy to troubleshoot. It's one of the most valuable features. It also doesn't take long to deploy and normally it comes with a three-year warranty."
"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."
"A minor issue that comes to mind is that, every once in a while, a hard drive will go bad."
"They should work on their upgrades, they're not smooth."
"I feel like there is too much automation; the user doesn't have any manual input."
"In the next release, I would like to see file-level encryption."
"Some services could be inserted directly into the SAN, so Pure Storage could complete with the HyperFlex."
"FlashArray's capacity for forecasting should be improved because it needs to be a bit more current. I think it's bundled with the deduplication and other compression factors. We need more user interfaces for forecasting in this software and more interfaces need to be integrated with this array management tool."
"It goes at about 95 percent, so we have had some performance issues. It is hard to clear them."
"I would like to have support available in Spanish."
"The upgrade process needs improvement. I should be able to swap it out, with zero downtime, with another array, down the road. I don't think Dell EMC has anything in the roadmap for this product line. I just don't want to have to deal with that anymore and all of our customers are pretty much the same."
"You can't use every feature, because it costs in performance. Therefore, you have to choose which features to use to achieve a better environment. That is why customers do not use every feature in Unity."
"Improve the administrative user interface so it is easier to work with. Currently, a simple task, such as removing a host from 100 LUNS, takes a lot of time. If they could improve LUN to host model to be more like the EMC VPLEX, for example, it would be great."
"I think there are a couple of things on the file side that we're lacking from the VNX world. It would be nice if we got some of those back. I think there are limitations on how many file systems you can back up at a time. Whereas you can do, I believe, eight continuous per data mover on the file side on the VNX, you can only do something like two or four on Unity. If they could step up to that, that would be good."
"They should have more wizards for customers so they can do more of the self-service types of functions, in terms of upgrades and patching, although it's pretty easy right now."
"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."
"It would be great if the solution could integrate an NVMe disk."
"The user interface could be improved. The Dell Compellent user interface is fantastic, but the Unity user interface is, in comparison, pretty lousy. It's functional, and I can do what I need, but the Dell Compellent user interface is so much more intuitive and user-friendly."
"Its performance could be faster."
"The features are limited."
"The solution could be more scalable, although it suits our present needs."
"Usually, when a part fails, we have to replace it and it takes a while. It would be better if the part could be available locally here in Kenya so we don't have to wait so long to repair the solution."
"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."
"In the next release, I would like to see support for Hyper-converged infrastructure."
"In the next release, I would like to see more functionality. But, again, it is an entry-level product."
"There could be a snapshot feature in the solution."
