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."We put a fair amount of stress on it because we run sequel workloads and we run web applications where the same web files are hit over and over. We have had almost zero stability issues with that SAN, that has been really great for us."
"It's very fast and very easy to use. It performs well and is both flexible and compatible. We like it because it's easy to use."
"The solution offers amazing performance."
"The connections are a lot faster than what we had in the past. One InfiniBand does what we did on all of our Fibre Channels."
"Data deduplication features make it easier to manage storage and forecast growth."
"Has also helped simplify storage for us. The other person we put in there, took about a week to implement. And we had both arrays set up within around four hours with a thirty minute drive time between the two locations."
"The security operating system is its most valuable feature because it's very simple, easy to use, and operate. You don't have to do very serious training to operate this equipment. It's user-friendly and pretty straightforward."
"The stability is very good. I've done destructive testing on it and never had any type of storage outages from it."
"The ease of management and “user-friendly” management environment (GUI)."
"We just started doing a bunch of automation where, if an end-user's home directory or departmental share gets filled, I can set certain things through a Unity API so that if it reaches 95 or 98 percent full, it will automatically expand. Now, instead of our getting a ticket and having to go in and do it manually, it does that for us."
"I like Unity XT's software-defined storage. It's a new feature that isn't widely used yet, but customers are impressed with it."
"We have resolved IT challenges with this solution. It sped up our environment. We went from spinning disk to all-flash, which reduced our footprint."
"Its most valuable feature is the storage alarm."
"I like that the solution is scalable. The initial setup is not complex. The basic licenses and software are included in the package. he primary advantage is that this product has been thoroughly tested and proven over time. I recommend this product."
"The most valuable features include snapshots, Thin Clones, and deduplication and compression."
"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."
"The product’s quality of service guarantees the performance of each workload."
"We are satisfied with the stability."
"Ability to cluster two storages together with HA availability."
"Scalable and stable storage array."
"The FlexClone feature is the solution's most valuable aspect."
"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 price of this solution is good."
"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 higher education moves slowly. We are still looking forward to implementing the full list of existing features."
"I would like to see data tiering to AWS."
"We would like to be able to connect to data tape for backup, specifically to the LTO backups."
"I would like to have an easy way to determine the cost per VM so that I can present a solution to our customers."
"Having something native in the Pure Storage ecosystem would make it integrated and in one single company, and we wouldn't have to work with multiple organizations."
"Pure Storage FlashArray could improve the recent file storage capabilities because it is lacking a lot of features."
"They should work on their upgrades, they're not smooth."
"The internal garbage collection process has been fixed recently in some OS updates so it is more efficient but that could be just a little better."
"In future releases, I would like to see automatic upgrades from one to the next, when this system is coming out and the next one is coming in; more akin to what Pure Storage is doing. That would be really helpful."
"The only issue is with the product's scalability because it's not as scalable as the other polished tools in the market."
"It's an expensive solution, particularly for medium companies. One device costs about 30,000 euros. The support contract is quite expensive as well. We are currently looking for other lower-cost solutions."
"This is a tier-three solution and it gives us what we need for archiving and backups."
"My only complaint would be some of the CLI Help files could be a little more detailed, but that's very minor complaint. We were trying to run some commands just to see how the storage snaps were interacting with the storage array, and it was a little difficult to look up exactly what commands should be run. The Help files detailing what exactly the commands did wasn't as detailed as we would have wanted them to be."
"What I'd like to see is a little more detail on the networking side. I can go into where it's showing me the replication, but when I go into the network it just gives me broad-based information. I don't know which replication job is actually feeding it. I have to go in and rely on other apps."
"Issues with slow responses from the support team."
"We are running VMware, and with the VNXe it was possible to restore. We're using Veeam for VMware backups and with the predecessor, it was possible to mount a backup or restore a backup from a storage snapshot. With the Unity 300, this is not possible."
"The Lenovo ThinkSystem DM Series was very hard to configure. Installation of the product was very hard. These are its areas for improvement."
"I would rate the support of Lenovo ThinkSystem DM Series a four out of five."
"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."
"Lenovo ThinkSystem DM Series could improve by having a snapshot feature. Additionally, there can be other features added to help restore the data faster."
"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."
"This is an expensive solution."
