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

"If a company is looking for an All-Flash Tier and they need extreme performance for individual workloads, Pure's the way to go, over something like a SolidFire."

"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."

"The latency is good."

"Everything, especially the VMs inside, is pretty fast."

"After the testing, it was clear to us that the Pure FlashArray X NVMe was the easiest to manage and configure and had the best performance that we had seen in all the arrays."

"It has good, reliable, and fast storage."

"The solution is scalable."

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

More Everpure FlashArray X NVMe pros

"This solution is good for virtualization and meets the need for CPU and RAM requirements."

"Lenovo ThinkSystem DE Series is simple to use"

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

"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."

"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."

"This solution is good for virtualization and meets the need for CPU and RAM requirements."

"I would rate the stability of Lenovo ThinkSystem DE Series as a ten."

"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."

More Lenovo ThinkSystem DE Series pros

"The FlexClone feature is the solution's most valuable aspect."

"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 Lenovo ThinkSystem is used for everything in our company from ERP to BI, for production, PLM, CAD for designing, and everything else."

"It has been a perfect fit for the workload that our customer is doing."

"The product’s quality of service guarantees the performance of each workload."

"The price of this solution is good."

"Lenovo offers a good variaty of Storage Systems. Starts with DS, then DE and the most sophisticated version - DM-Series."

"Ability to cluster two storages together with HA availability."

More Lenovo ThinkSystem DM Series pros

Cons

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

"I would like to see replication and DR features in the next release of this solution."

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

"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."

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

"The tool's pricing is higher than competitors."

"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."

"The UI for this solution needs to be improved."

More Everpure FlashArray X NVMe cons

"Usually, when a part fails, we have to replace it and it takes a while. It would be better if the part could be available locally here in Kenya so we don't have to wait so long to repair the solution."

"Its performance could be faster."

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

"Improvements can be made to the product's performance."

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

"The product could support advanced software integrations."

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

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

More Lenovo ThinkSystem DE Series cons

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

"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."

"This is an expensive solution."

"Lenovo could have a wider variety of storage solutions in the NAS space."

"Many people do not realize that Lenovo has a storage solution, so better marketing from the vendor is needed."

"The solution should change the licensing model and allow customers to choose features based on their requirements."

"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."

More Lenovo ThinkSystem DM Series cons

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."

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

"The support cost per array is about $20,000 a year for 24/7 support."

"The licensing is on a yearly basis."

"With Pure Storage, we would like to continue seeing price reductions with flash storage. I don't think we're any different than anybody else when we continue to look to the industry for price reductions of both NVMe and traditional SSD storage. We would like to see these prices continue to decline and erode, even displacing large spinning disks."

"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."

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

"The tool is an investment that we've budgeted for. While the prices may be higher than those of other vendors, we see it as a market leader with benefits. We don't regret purchasing it."

More Everpure FlashArray X NVMe pricing and cost advice

"All of the features are bundled together, and you can renew the bundle with all of the features included."

"The solution's price could be better."

"It is an expensive solution."

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

"The pricing for this solution is good compared to HP or Dell EMC."

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

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

"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."

More Lenovo ThinkSystem DE Series pricing and cost advice

"The solution is highly-priced."

"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."

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