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."This solution is very scalable."
"The compression and deduplication features help to make the best use of the capacity."
"The scalability is good."
"Performance, dedupe, and that it works well with database workloads are its most valuable features."
"FlashArray has many valuable features. It's very user-friendly and it has high availability, so there is comparatively less downtime. During maintenance, there is no shutdown procedure, so you can directly power off the Array and manage the shutdown process without any data loss, which is a unique feature. Managing replication and data migration is also very easy."
"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."
"The support team is available all the time and they seem to know what they are doing."
"The first year, we started out with one or five terabytes and it took what was 20 terabytes of storage down to less than one terabyte."
"The most valuable feature of Dell Unity XT is its support of protocols for both block, and file levels. It has the features a store solution should have."
"We've never had an issue with storage."
"It does great deduplication. From a storage perspective, we save money being able to dedupe right on the disk"
"Real Unified Storage (Block, File, VVols) in a unique 2U hardware."
"The solution is so easy to manage that I forget it is there."
"It is nice the way ESRS works with remote support, being able to remote in and take a look at problems proactively."
"We are happy with the way we have Dell EMC Unity XT configured."
"The multiprotocol support. It's supporting NFS, fiber channel, CIFS, and these kinds of things. The multiprotocol is very attractive."
"The product’s quality of service guarantees the performance of each workload."
"The price of this solution is good."
"Ability to cluster two storages together with HA availability."
"The solution offers very good reliable systems and storage for our clients."
"The FlexClone feature is the solution's most valuable aspect."
"We are satisfied with the stability."
"The most valuable feature of the Lenovo ThinkSystem DM Series is its ability to store data well."
"Scalable and stable storage array."
"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 price should be lower."
"I would rate this solution an eight because we have had outages. The commit times went very high in the database. The whole array went down so our customers were down for around eight hours. This was a very big outage which could have been our fault because we didn't do the upgrade in time."
"We haven't seen ROI."
"I would like to get a weekly report of how our storage has been used, and if there is any storage sitting there not being used."
"Just some nit picky stuff, like allowing servers and volumes to be grouped. Therefore, it would easier to work with them in the GUI."
"I would like to have an easy way to determine the cost per VM so that I can present a solution to our customers."
"I would love to see a true one click upgrade solution. Right now, you have to click and schedule an appointment with Pure Storage to be able to upgrade. I would love for it to automatically download, install, and fall-over every controller as it updates."
"There's always room for improvement with the UI. That can be a little cumbersome at times."
"Scalability for the 650F is good, but I was expecting a little bit more."
"The monitoring part could be better. With EMC storage systems - or Unity and VPLEX, because I'm using them, for the moment - the monitoring part is very difficult. They should improve this to have a better reporting system."
"I haven't seen the roadmap for this solution."
"The initial setup is not so straightforward if you don't have experience with storage arrays."
"One of the issues we've had is that controllers have crashed several times... We've had a lot of problems with the storage processor, SPBs. We've actually had them crash."
"The storage processors have less port expansion than previous high-end VNX arrays. Data compression is only available in all-flash pools."
"There are features still to come, like compression and deduplication on hybrid platforms, VDM improvements to be developed for NAS environments, and also improvements in the “self-migration” tools to push or pool information (to assist the migrations to and mostly from third-party arrays)."
"The solution should change the licensing model and allow customers to choose features based on their requirements."
"Many people do not realize that Lenovo has a storage solution, so better marketing from the vendor is needed."
"I would like Lenovo to add a feature like IBM Easy Tier to DM Series. This is a crucial feature for the customers."
"This is an expensive solution."
"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."
"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 Lenovo ThinkSystem DM Series was very hard to configure. Installation of the product was very hard. These are its areas for improvement."
