Find out what your peers are saying about Dell Technologies, NetApp, Pure Storage and others in All-Flash Storage."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 is its data reduction."
"The connections are a lot faster than what we had in the past. One InfiniBand does what we did on all of our Fibre Channels."
"The support team is available all the time and they seem to know what they are doing."
"We find the ease of usability and setup valuable."
"It is the SAN backbone for our company."
"The performance and the ever-growing maintenance are the most valuable features of this solution."
"The solution has probably reduced my power use substantially."
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"The initial setup is straightforward."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"High performance and ease-of-management are the most valuable features."
"It performed great originally, and when it performed great, it was awesome."
"Data Compression: Up to 80% space reduction in the database"
"Scalable and stable storage array."
"Ability to cluster two storages together with HA availability."
"The solution offers very good reliable systems and storage for our clients."
"We are satisfied with the stability."
"The most valuable feature of the Lenovo ThinkSystem DM Series is its ability to store data well."
"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 product’s quality of service guarantees the performance of each workload."
"The price of this solution is good."
"There are many features which need to be added, particularly on the replication side."
"They could improve the price."
"FlashArray's capacity for forecasting should be improved because it needs to be a bit more current. I think it's bundled with the deduplication and other compression factors. We need more user interfaces for forecasting in this software and more interfaces need to be integrated with this array management tool."
"The technical support is okay, but could be improved."
"Self-backup is the only feature lacking in this solution."
"What it needs to do is work a little closer with solutions, like VMware, so it understands the particular workloads that are on it. Today, it does not understand the applications which are running against it."
"We would like to see better troubleshooting aspects. It helps us if we can find out where the problem is. Right now, it's difficult. Sometimes it's difficult to pinpoint the issue. If they had more visibility and more troubleshooting feature built into the tool that would really help."
"The system has dual controllers but does not have a high level of resiliency built-in."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"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 only keeps one hour of real-time data without the ability to do deep analysis of each element."
"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."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"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."
"It's somewhat scalable, but maybe not so much as some of the competition."
"Snapshots are not as easy to access as on a NetApp device."
"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 licensing model needs to be revisited. It needs to be simplified."
"The solution should change the licensing model and allow customers to choose features based on their requirements."
"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."
"The Lenovo ThinkSystem DM Series was very hard to configure. Installation of the product was very hard. These are its areas for improvement."
