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."Data deduplication is one feature I found to be the most valuable in the tool...Stability-wise, I rate the solution a ten out of ten."
"We like the speed. It's very low latency. In virtualization, you can mask lots of problems, and even in code you can mask lots of problems, with low latency. It's just pure speed and low latency."
"It is pretty much just plug and play. There is not that much to do with it. It is very easy to use."
"It simplifies 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."
"Because we were able to afford to go all flash, we don't manage the tiers, we're not moving data up, and we're not waiting for overnight cycles."
"Having an intuitive user interface to get things running is great."
"The initial setup was straightforward in the way that it was a database vacuum storage."
"It's unified, it does block and file, so that is pretty important to my customers who might have file servers around their environment. I can roll them all up into a single array, as well as provide block storage for them on one array."
"Replication of the communication object (COB) scenarios"
"The most valuable feature is the performance. It's still an all-flash array at a good price point."
"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."
"Stable flash storage platform with good scalability, efficiency, and speed."
"The product has helpful local technical support."
"Integration is easy with this product."
"The most valuable features are its performance and simplicity."
"The price of this solution is good."
"The product’s quality of service guarantees the performance of each workload."
"The most valuable feature of the Lenovo ThinkSystem DM Series is its ability to store data well."
"The solution offers very good reliable systems and storage for our clients."
"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."
"Ability to cluster two storages together with HA availability."
"The FlexClone feature is the solution's most valuable aspect."
"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."
"There are scenarios with very specific functionality around VMware integration particularly to do with the way we'd like to manage LUNs in VMware. The tools are pretty good but there's room for improvement there."
"In the next release of this solution, we would like to see automated copy data management for SQL Server."
"I would like some performance analytics which go deeper than today. It should be specific to some hosts and applications. This would be good."
"I would rate this solution an eight. To make it a ten it would have to be a little cheaper."
"Had some issues with Purity not being entirely compatible with VMware ESXi."
"Pure Storage FlashArray could improve in the area of cryptographic information in the consoles. The user-friendliness could improve. The Pure Storage FlashArray team should come and log into the system with their maintenance credentials and then pull out the information as evidence of cryptography."
"Pure Storage FlashArray could improve some aspects. There are certain features that are good and there are some features that I see some issues with at the technical level. Those issues are related to replication. They need to resolve those issues, which I have already highlighted to the Pure team. Additionally, there are some issues in the active cluster that could improve."
"Part of our company works on Dell EMC because Pure Storage did not have synchronous applications when we were purchasing our products."
"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."
"Because we can do synchronous replication between the two sites, this made the setup challenging for this piece. They did not know how to set this up initially. We ended up having to do bidirectional synchronous replication."
"I would like better integration with RecoverPoint. My major issue with the solution, all around, has been RecoverPoint more than Unity. While I like the easy user interface, I would like some more advanced features for troubleshooting built into the product, so that we can do more in-depth problem-solving."
"I miss storage groups. Now, if I have to add a LUN to a cluster, multiple host, I have to know which host is in that cluster. I have to write it down and that makes it hard. In VNX and earlier, I could simply put a LUN on a storage group and every host in the group had the LUN. This lack bothers me a lot because it takes a lot of time and mistakes are made. Sometimes, a Hyper-V host gets a VMware LUN and vice-versa. Not good."
"I don't know where the hybrid cloud might be going or what connectivity there is between what was recently released as far as AWS and being able to manage both of them. Maybe there is an on-prem and an AWS instance in the same window, like a single pane, but I would like to see something along those lines, where there wouldn't be two locations to manage storage."
"The support portal needs fixing. Accessing a service request on the support portal seems to be a bit difficult, as opposed to just calling the 800 number."
"Since Dell took over EMC, the support has been very bad. Before, the support was fine. Now, the support is slow or they don't react."
"We'd like to see a cheaper version of an all-flash array in that footprint."
"I would rate the support of Lenovo ThinkSystem DM Series a four out of five."
"Lenovo ThinkSystem DM Series could improve by having a snapshot feature. Additionally, there can be other features added to help restore the data faster."
"Many people do not realize that Lenovo has a storage solution, so better marketing from the vendor is needed."
"The solution should change the licensing model and allow customers to choose features based on their requirements."
"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."
"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 like Lenovo to add a feature like IBM Easy Tier to DM Series. This is a crucial feature for the customers."
