We performed a comparison between IBM FlashSystem 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."The latency is good."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"The most valuable feature of this solution is reliability."
"The initial setup was extremely simple and straightforward."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"The most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."
"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."
"Ability to manage third-party arrays and virtualise them: One screen to control multiple arrays. Simplified administration."
"IBM FlashSystem is a flexible solution with plenty of features."
"The all-flash storage has tier replication capabilities."
"Data deduplication is one of the most valuable features of this solution."
"The most valuable features are deduplication and compression, which together, enable you to have more space."
"High availability and enhanced security; Proven dependability; Data compression with hardware acceleration; Advanced copy services features are all in this product."
"Flash disk with Easy Tier option"
"The speed and the ease of installation are the most valuable features."
"The most valuable feature of the Lenovo ThinkSystem DM Series is its ability to store data well."
"The FlexClone feature is the solution's most valuable aspect."
"The product’s quality of service guarantees the performance of each workload."
"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 price of this solution is good."
"We are satisfied with the stability."
"Ability to cluster two storages together with HA availability."
"The solution offers very good reliable systems and storage for our clients."
"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"I would like to see replication and DR features in the next release of this solution."
"The tool's pricing is higher than competitors."
"There is room for improvement in the pricing of the product."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"The UI for this solution needs to be improved."
"In terms of what needs improvement, the dashboard and management could be simplified."
"The solution is not easy to implement. It takes a lot of time to study the product and it's a little complicated in general."
"It has room for improvement in the area of stability."
"Sometimes the performance is effective but it gets resolved in the process."
"With regards to the IBM V7000 storage system, where we have multiple tiers of storage, a heat map would show I/O distribution across the tiers of storage."
"The price is very costly."
"I think the only thing the developers can look at, is that it is limited to 25 gigabytes currently. In the next release they might want to increase that."
"If you want to expand, you cannot expand the disc enclosure. You have to buy a total individual node. Sometimes, this is difficult because we are just looking for capacity and not a node."
"The GUI for monitoring performance metrics could provide better visibility. For example, it doesn't let me segregate the IOPS per volume."
"This is an expensive solution."
"The solution needs a simpler licensing theme around the DM series. The problem is if you only need one of the features, you still have to buy the whole thing. The licensing needs to be more granular or flexible so you have the option to only license FlexCone or Inline Compression features."
"I would like Lenovo to add a feature like IBM Easy Tier to DM Series. This is a crucial feature for the customers."
"The solution should change the licensing model and allow customers to choose features based on their requirements."
"Lenovo ThinkSystem DM Series could improve by having a snapshot feature. Additionally, there can be other features added to help restore the data faster."
"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."
"Many people do not realize that Lenovo has a storage solution, so better marketing from the vendor is needed."
"The Lenovo ThinkSystem DM Series was very hard to configure. Installation of the product was very hard. These are its areas for improvement."
