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 security operating system is its most valuable feature because it's very simple, easy to use, and operate. You don't have to do very serious training to operate this equipment. It's user-friendly and pretty straightforward."
"We've been using FlashArray's snapshot for backups. Their replication across sites and response time are also excellent."
"They are quite responsive and our local team was pretty good."
"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 actually very stable"
"The tool has reduced our power consumption."
"Pure Storage technology allowed us to automate tasks, reducing something which started as a 12-hour turnaround down to about 15 minutes."
"The simplicity of it. The performance is good, but the simplicity is the best thing. Storage management is quite complex, but Pure Storage is easy to manage."
"Most of the features for the reduction in data compression are useful. It is also very easy to use and administer. Its performance is also good."
"User friendly management interface."
"The performance of the All-Flash System is very good. There is more enhanced performance and data production in the solution, which I appreciate."
"The performance of IBM FlashSystem is very good. The new technology and high throughput have given us more confidence in the solution. The management of the system has improved and we can control the monitoring system alerts and multiple FlashSystems with the Enterprise Cloud Edition, which is free. The migration of recently stored data to a new flash is much easier. You can move your data because you can utilize it externally."
"It's a mature product. It's like a BMW that evolves consistently."
"We are a 100% satisfied with the stability of the solution."
"This solution is really user friendly. It also offers good performance and is highly reliable."
"We've found the solution to be very stable so far."
"The product’s quality of service guarantees the performance of each workload."
"Ability to cluster two storages together with HA availability."
"The price of this solution is good."
"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 solution offers very good reliable systems and storage for our clients."
"The most valuable feature of the Lenovo ThinkSystem DM Series is its ability to store data well."
"We are satisfied with the stability."
"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 would like to see some improvements on the FlashBlade side around the CIFS space support. I am not super familiar with all the different NAS protocols that they run on their box, but there could be some improvements made on SMB CIFS side."
"There are a lot of things to improve."
"Data reduction is an area that needs improvement. There is a garbage collection service that runs but during that time, system utilization increases."
"The price could be better."
"The credentials on the iSCSI interface are only available to type in with the Chrome browser, and not with the Firefox browser."
"They should work on their upgrades, they're not smooth."
"We did have one hiccup with the integration of vCenter. When we were installing Pure Storage, we were using vCenter 6.7, which defaults to the HTML5 Web Client. The current plugin for Pure Storage doesn't show up in that client at all. You have to go and use the legacy FlexFlash client to see the Pure Storage plugin in vCenter."
"We would like to be able to connect to data tape for backup, specifically to the LTO backups."
"The pricing could be improved, but I think it's getting better and better with each version. IBM needs to implement NAS storage again, as this is a big flaw. Dell EMC is very good at this and if you compared them based on NAS storage, Dell EMC would win right away. IBM's solution for NAS storage is very complicated. We don't have a storage box that provides file sharing from itself, we have to put software on it and go through a whole complicated process. It should be simplified."
"A big area for improvement is that the data reduction pool feature is not recommended for use in a production environment because it has stability and performance issues."
"In IBM FlashSystem, data reduction is an area with shortcomings where improvements can be made in the future."
"It has room for improvement in the area of stability."
"There could be some extra features added."
"Sometimes the performance is effective but it gets resolved in the process."
"This solution could be improved by offering greater amounts of storage."
"Events/log analysis tools."
"I would like Lenovo to add a feature like IBM Easy Tier to DM Series. This is a crucial feature for the customers."
"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."
"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."
"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."
"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."
"The Lenovo ThinkSystem DM Series was very hard to configure. Installation of the product was very hard. These are its areas for improvement."
