We performed a comparison between DDN IntelliFlash and Lenovo ThinkSystem DM Series based on real PeerSpot user reviews.
Find out what your peers are saying about Dell Technologies, NetApp, Pure Storage and others in All-Flash Storage."With Pure Storage, we don't see any latency or IOPS. It has been a very seamless integration."
"The scalability options are very nice because you can scale it much better and faster. The scalability was there in the previous environment also, but this is far better than what we had before. It basically helps the user in case they are looking for more storage. We can scale it much faster."
"For us, the most valuable feature is the compression and deduplication. Being able to deploy a three to one ratio for storage is absolutely critical in today's world with the growing need for storage and the growing need for more space."
"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."
"We can store more for a cheaper price as opposed to paying for larger devices and larger rack spaces which get outdated sooner and which we'd have to change every two years. It simplifies storage for us."
"The speed is the most valuable feature of this solution."
"The solution is easy to scale. I'm running two environments right now, so I need to scale. I'm running a part technology. I've got an A-side and a B-side."
"The most valuable features are the replication of data and the continuous snapshot that we can take from the disc."
"Data Compression: Up to 80% space reduction in the database"
"High performance and ease-of-management are the most valuable features."
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"It performed great originally, and when it performed great, it was awesome."
"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"The initial setup is straightforward."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"The most valuable feature of the Lenovo ThinkSystem DM Series is its ability to store data well."
"We are satisfied with the stability."
"Ability to cluster two storages together with HA availability."
"The FlexClone feature is the solution's most valuable aspect."
"Scalable and stable storage array."
"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."
"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."
"I recognize it's a difficult challenge, but I would like to see them make the pricing more reasonable."
"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."
"We would like to see more cloud support, which we know is coming, although it's not out yet. It's going to be released in the next versions. That would be the biggest win, if additional cloud support is built into the array."
"The number of Filesystems is limited, which it is not on the EMC VNX."
"I would like to see data tiering to AWS."
"It would be nice if Pure had something in its portfolio that provided higher deduplication and compression for backups."
"In some cases, we get into very in-depth conversations around movement of specific data and, what's more, chunk sizes. The documentation lacked any description or information on that."
"We haven't seen ROI."
"We had just one small stability problem with power flapping and it did not start up again automatically. We had to access service ports and manually restart the storage processors."
"It's somewhat scalable, but maybe not so much as some of the competition."
"In the proxy section you can’t choose a user account and password, so it is not allowed at the moment to go out, if customer has such constellation."
"Snapshots are not as easy to access as on a NetApp device."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"Performance is horrible now. Our original intent was to buy new storage in about two years. But since it became a critical urgency for us, we decided to purchase a new one in two or three months."
"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."
"This is an expensive solution."
"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."
"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."
