We performed a comparison between Dell PowerStore 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."It's just very easy for general block storage."
"We've been using FlashArray's snapshot for backups. Their replication across sites and response time are also excellent."
"The management is simple in Pure Storage FlashArray."
"The solution is very reliable."
"NVMe data storage platform that's easy to set up and easy to use. It's stable, with a lower response time, and quick technical support."
"The speed is one of the most valuable features of Pure Storage FlashArray."
"Provides fast access and is user-friendly."
"The compression and deduplication features help to make the best use of the capacity."
"This solution is very useful to us as we use it internally for all of the services that we need. We use it as a lab and we showcase new technology to the customers and how it can help them going forward."
"When compared to Pure Storage, Dell PowerStore's cost was quite attractive."
"For access from virtual machines, iSCSI, and NFS, it is very good. It helps increase performance."
"Currently, the features of replication and deduplication have been very important to us."
"PowerStore is easy to use. All the drives use soft encryption. To upgrade it, you download the app, and it runs by itself. It's very easy to deploy, share, and create volumes."
"The compression is excellent."
"There is no complicated configuration for queries and calls. You just create a model and go."
"Reliable, with comprehensive features and a well-established support base."
"Scalable and stable storage array."
"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 most valuable feature of the Lenovo ThinkSystem DM Series is its ability to store data well."
"The product’s quality of service guarantees the performance of each workload."
"It would be good to have metrics of the box's performance so we can see what it delivers, but currently, I can't see what it's actually doing."
"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."
"The GUI could improve, it could be more intuitive. There is hidden functionality."
"The backend of this solution utilizes an Active/Passive architecture, rather than an Active/Active architecture, which is a disadvantage, when compared to some of its competitors. Its storage capacity should be expanded in the next release."
"The price of Pure Storage FlashArray could be better."
"When we were doing some tests, we found that there was an I/O freeze when they were switching the controller."
"Pricing could be better in comparison to other solutions."
"It is way in excess of what we need. If anything, we could see a bit more speed. I'm just comparing it with what some of my colleagues who are implementing their own systems do."
"The only area I can highlight for improvement is that the 4:1 data reduction target has not been reached. This may be due to an issue with Dell EMC's initial analysis of data compression. As a result, we have had to add new physical disks to reach our goal of total available disk space."
"You cannot delegate permissions."
"Dell PowerStore is a good solution overall, but some models could support hypervisors better by allowing for more customization and flexibility for customer needs."
"It was very new when we first deployed it a year ago. Even the upgrade processes and knowing what to expect, as well as documentation, could be more robust."
"It needs more mature code."
"The NAS part is very poor. It's very basic. Even Dell EMC has said that to us. We are waiting for version 3 of PowerStore for that. This must be improved and it is in the roadmap."
"The customer service and support are bad."
"Horizontal scaling has room 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."
"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."
"The solution should change the licensing model and allow customers to choose features based on their requirements."
"The Lenovo ThinkSystem DM Series was very hard to configure. Installation of the product was very hard. These are its areas for improvement."
