We performed a comparison between Dell Unity XT and Lenovo ThinkSystem DM 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."Technical support has been helpful and responsive."
"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."
"Pure has signature security technology, which cannot be deleted, even if you are an administrator."
"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."
"The latency is good."
"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"The most valuable feature of this solution is its ease of use."
"I like that when you log in it gives you a dashboard of what your storage looks like."
"The flash aspects of the Unity make it incredibly fast. The fact that you get that much storage directly on what is basically a 3U box to us, that density has been really useful."
"The All-Flash models are pretty fast for the vast majority of our remote workloads."
"I don't think I've ever seen latencies above 10 milliseconds unless it was something that wasn't the array that was messing up. The thing is rock-solid."
"The solution overall has high performance."
"The most valuable features of Dell Unity XT are the data compression for all of our VMs up to four times and the performance is good."
"Unified block and file storage without the need of control stations and data movers. This simplifies administration and deployment and requires less rack space."
"It gives me the flexibility with its ability to replicate to itself and the ability to use the Dell EMC Cloud as an option. That's always sitting there and waiting if we need it."
"The product’s quality of service guarantees the performance of each workload."
"We are satisfied with the stability."
"The solution offers very good reliable systems and storage for our clients."
"Ability to cluster two storages together with HA availability."
"The price of this solution is good."
"The most valuable feature of the Lenovo ThinkSystem DM Series is its ability to store data well."
"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."
"The most valuable feature of Lenovo ThinkSystem DM Series is its capability to tier to the cloud, such as Microsoft Azure or Amazon AWS. Additionally, the integration is good and they are user-friendly."
"The tool's pricing is higher than competitors."
"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"They could add more support for file storage and different types of storage."
"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."
"The software layer has to improve."
"I'd like to see the product implement active replication for vehicles such as VMware."
"There is room for improvement in the pricing of the product."
"We have only used this solution for less than one year so I don't have any improvements suggestions yet."
"Problems with I/O modules, with bugs that came out that really should have been caught before the product was released."
"Support Responsiveness & time to fix bugs should be improved."
"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."
"We cannot connect directly with Dell due to sanctions."
"Dell EMC's competitor has a clustering technology. In the next release, it would be nice if they could build that into the product."
"Last (and I understand that it has a low chance of being implemented) the copy services currently are redirect on write. It would be great if the administrator could choose between redirect on write and copy on write, when configuring copy job."
"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."
"The Lenovo ThinkSystem DM Series was very hard to configure. Installation of the product was very hard. These are its areas for improvement."
"This is an expensive solution."
"The tool's pricing is high."
"The solution should change the licensing model and allow customers to choose features based on their requirements."
"The licensing model needs to be revisited. It needs to be simplified."
"I would rate the support of Lenovo ThinkSystem DM Series a four out of five."
"I would like Lenovo to add a feature like IBM Easy Tier to DM Series. This is a crucial feature for the customers."
"It takes a very long time to enter the management console, as well as to restart the system, and these are things that should be improved."
