Eugene Hemphill - PeerSpot reviewer
Helps to save money and resources with the data compression feature
One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them. One way to improve the product is to add an operational assistant that doesn't depend on VMware. It could also establish more alliances with other operational systems.

Provides good stability and is reliable in terms of performance
The solution is reliable in terms of performance They should include a snapshot feature for the solution. We have been using the solution for two to three years. The solution is stable. We have 60 solution users in our organization. The solution's initial setup process is easy. It takes three…

Reliable and fast servers with good support
We use on-premise servers with Lenovo ThinkSystem. We set up Hyper-V and load multiple types of servers including a domain controller, a SQL Server, and application servers The solution provides fast servers that are reasonably priced. We set up RAID ten to ensure drive redundancy, leading to…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."
"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."
"I appreciate the performance."
"Technical support has been helpful and responsive."
"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."
"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."
"The latency is good."
"We are satisfied with the performance as it is significantly faster compared to traditional storage options."
"The solution is very easy to set up."
"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."
"Lenovo ThinkSystem DE Series is simple to use"
"The most valuable features of the Lenovo ThinkSystem DE Series are the dual controllers, available installation documentation, and the option of multiple host bus adapter interfaces."
"I would rate the stability of Lenovo ThinkSystem DE Series as a ten."
"Its initial setup process is easy."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"The solution is very easy to troubleshoot. It's one of the most valuable features. It also doesn't take long to deploy and normally it comes with a three-year warranty."
"The solution offers very good reliable systems and storage for our clients."
"The price of this solution is good."
"The product’s quality of service guarantees the performance of each workload."
"The servers are fast and affordable."
"Ability to cluster two storages together with HA availability."
"The most valuable feature of the Lenovo ThinkSystem DM Series is its ability to store data well."
"Scalable and stable storage array."
"The FlexClone feature is the solution's most valuable aspect."
 

Cons

"We need better data deduplication."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"In the future, I would like to see integration with enterprise backup systems."
"I would like to see replication and DR features in the next release of this solution."
"I would like to see some AI features that would allow arrays to intelligently identify threats or unusual behavior in the data pattern and give an alert."
"The UI for this solution needs to be improved."
"The product could support advanced software integrations."
"The type of connection that is used in Lenovo ThinkSystem DE Series should be improved."
"Improvements can be made to the product's performance."
"In the next release, I would like to see support for Hyper-converged infrastructure."
"It would be useful to have structured solutions replicated to other sites."
"The solution could be more scalable, although it suits our present needs."
"The features are limited."
"Its performance could be faster."
"Lenovo ThinkSystem DM Series is not stable. If I have sold fifty boxes, about fifty percent of them experienced failure."
"Many people do not realize that Lenovo has a storage solution, so better marketing from the vendor is needed."
"The licensing model needs to be revisited. It needs to be simplified."
"Lenovo ThinkSystem DM Series could improve by having a snapshot feature. Additionally, there can be other features added to help restore the data faster."
"This is an expensive solution."
"The solution should change the licensing model and allow customers to choose features based on their requirements."
"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 tool's pricing is high."
 

Pricing and Cost Advice

"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"Given its price, Pure is not the first option."
"Its price could be better. It is not too expensive, but it is the high-end cost. It is kind of a Rolls-Royce. You pay a lot, but you get a lot out of it. So, the price pressure on the way down would be great, but at the end of the day, if you need to do the work, you just pay for it."
"The licensing is on a yearly basis."
"Pretty much everything that you need is licensed when you buy the product. Licensing to me is different than the maintenance cost, but they can bleed into one another. We buy the product, and we expect three years of support bundled into what we negotiate on our storage arrays. I would start to see maintenance costs going into the fourth year, but we're not there yet."
"Our licensing fees are $500,000+ USD."
"As far as the licensing costs, everything is included in the license."
"We pay approximately $50,000 USD per year in licensing fees."
"The solution's price could be better."
"It is an expensive solution."
"For an all-flash setup, the cost is around $20,000 for a decent configuration."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
"The pricing is fair and low compared to other products in this category."
"The pricing for this solution is good compared to HP or Dell EMC."
"The price of the Lenovo ThinkSystem DE Series is a one-time purchase. There is a global price list available to find the price of the solution."
"The best thing about this solution is its price, which reduces our costs."
"The solution is highly-priced."
"The solution's pricing is similar to Dell and HPE."
"Lenovo offers two software tiers for the DM Series: basic and premium. If you need more features like the MetroCluster, you must buy the premium version. You can stick to the basic software if you don't need MetroCluster or features like asynchronous replication. That makes DM Series a little cheaper."
"The price of the Lenovo ThinkSystem DM Series is good."
