Supports efficient storage management through volume snapshots and offers reliable non-disruptive upgrades

I have no specific improvements to suggest for Pure FlashArray X NVMe at this time. The performance statistics could be enhanced. I can see the performance statistics in the Pure Storage console, but it does not show the performance by 4K byte unit. It displays IOPS and bandwidth, but IOPS is about real use, and I want to know how many IOPS are currently running in 4K byte units. I cannot see that IOPS because most storage systems report their performance by 4K byte unit. I want to see Pure Storage performance by 4K byte unit to compare with other storage or other internal NVMe SSD.

Complicated deployment and poor support persist, affecting overall satisfaction

The deployment process of Lenovo ThinkSystem DM Series is very complicated compared to previous GUI systems. Many customers have lost data while configuring it, indicating a need for improvement. The after-sales service is also very poor. Furthermore, it does not offer basic features like deduplication, and the service is generally considered to be very bad.

Quotes from Members

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

Pros

"We are satisfied with the performance as it is significantly faster compared to traditional storage options."

"The high availability of the product is the most valuable feature."

"I appreciate the performance."

"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."

"We generally always advise people to make the choice to go with Pure Storage because they won't regret it."

"The latency is good."

"Technical support has been helpful and responsive."

"One of the best features is the support, which is excellent."

More Everpure FlashArray X NVMe pros

"The solution's initial setup process is easy."

"Lenovo ThinkSystem DE Series is simple to use"

"Its initial setup process is easy."

"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."

"Lenovo ThinkSystem DE Series is quite an elementary box, no frills. It does not have all the functionality of the DM but it is acceptable, it does its task. It integrates pretty well."

"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions. It's also easy to use."

"The solution is very easy to set up."

More Lenovo ThinkSystem DE Series pros

"The solution offers very good reliable systems and storage for our clients."

Cons

"I'd like to see the product implement active replication for vehicles such as VMware."

"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."

"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."

"In the future, I would like to see integration with enterprise backup systems."

"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."

"We have run into a couple of instances recently where we are running out of space."

"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."

More Everpure FlashArray X NVMe cons

"The solution could be more scalable, although it suits our present needs."

"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."

"While it is a reliable product, it could be improved. It would be useful to have structured solutions replicated to other sites."

"The type of connection that is used in Lenovo ThinkSystem DE Series should be improved."

"You can not buy a lot of options for these devices. There are a lot of things that it does not do."

"The solution could be more scalable, although it suits our present needs."

"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration."

"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."

More Lenovo ThinkSystem DE Series cons

"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 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."

"In comparison with other similar solutions, I think this one is the most expensive."

"There might be improvements needed in drive throughput as disk speed has been a limitation on Windows servers."

"The solution needs a simpler licensing theme around the DM series."

"I would rate the support of Lenovo ThinkSystem DM Series a four out of five."

"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."

Pricing and Cost Advice

"The tool's pricing is cheap; I rate it a six to seven out of ten. Most of our sales are not subscription-based. We sell the hardware, and customers keep using it. They only renew the service part annually. The support can be a bit pricey, but the solution is more cost-effective than anything else out there."

"Our licensing fees are $500,000+ USD."

"The product is expensive."

"They can tout the functionality and cutting edge technology that they have, but that's where the price tag comes in. The cost is high, but I think as they grow their business and get more customers that it will probably go down a little bit."

"As far as the licensing costs, everything is included in the license."

"Given its price, Pure is not the first option."

"Pure FlashArray X NVMe’s pricing is cheaper than other products."

"With VMware, we pay $300,000 annually."

More Everpure FlashArray X NVMe pricing and cost advice

"For an all-flash setup, the cost is around $20,000 for a decent configuration."

"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."

"It is an expensive solution."

"The pricing is fair and low compared to other products in this category."

"The solution's price could be better."

"We have a five-year contract for providing support."

"The best thing about this solution is its price, which reduces our costs."

More Lenovo ThinkSystem DE Series pricing and cost advice

"The solution is highly-priced."

"The price of the Lenovo ThinkSystem DM Series is good."

"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 solution's pricing is similar to Dell and HPE."
