Featured Reviews

Jaehoon Oh

Chief Technology Officer at Lambda256

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.

A solution with a simple configuration and good stability but it's quite expensive

Access to technical support should be improved for our region. Technical support is good, but they're very hard to access. When we have a problem with this storage, it's usually related to a very bad configuration. All-Flash Storage is very, very expensive. They are important solutions so I don't really have any ideas about how to rectify this. The device could use better monitoring tools.

Service manager at Crescent Technologies

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.

"Improved performance by more than 50x on our application."

"It provides a full feature set without separate licensing (deduplication, compression, snapshot, asynchronous replication, stable performance, etc.)."

"The increased performance is many times above our previous array performance in all metrics. Integration with vSphere features is also a definite plus."

"The K2 has basically removed storage as a bottleneck in our datacenter."

"Data reduction and snapshot abilities: Smaller footprint in the datacenter (lower cost for power, cooling, etc.)."

"Scale out is a differentiator for them, especially in the enterprise market. It's key for a lot of customers."

More Kaminario K2 [EOL] pros

More Lenovo ThinkSystem DM Series pros

Cons

"In terms of what needs improvement, the dashboard and management could be simplified."

"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."

"It is on the expensive side."

"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."

"In the next release, I would like to see real-time analytics for further insight into consumption models."

"We would like to see more visibility into garbage collection and CPU performance in the GUI."

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

"We would like to see VNC integration or be able to use Pure Storage with VNC."

More Everpure FlashArray X NVMe cons

"A single pane of glass to monitor/manage multiple arrays would be helpful."

"I think it should have better performance with small files. With big data, its performance is top notch, but it is difficult to load small files."

"The front panel of the drive shelf doesn't always seat firmly."

"There are a few areas where the system could be improved. Examples would be that the system currently has a 15TB LUN size limit and that snapshots need to be scheduled through script API instead of the GUI."

"The system currently has a 15TB LUN size limit and that snapshots need to be scheduled through script API instead of the GUI."

"I'd give it a perfect rating if I could push it to 300,000 IOPS like they promote; we just haven't been able to push that many IOPS out of our system."

"Access to technical support should be improved for our region. Technical support is good, but they're very hard to access."

More Kaminario K2 [EOL] cons

"The Lenovo ThinkSystem DM Series was very hard to configure. Installation of the product was very hard."

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

"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 tool's pricing is high."

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

"The Lenovo DM Series is an excellent storage product, but I think it isn't competitive with other companies like Dell EMC and IBM because IBM products are very cheap and have more features."

"Lenovo ThinkSystem DM Series is not stable. If I have sold fifty boxes, about fifty percent of them experienced failure."

More Lenovo ThinkSystem DM Series cons

Pricing and Cost Advice

"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."

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

"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."

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

"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."

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

"We pay approximately $50,000 USD per year in licensing fees."

"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."

More Everpure FlashArray X NVMe pricing and cost advice

"Kaminario is very competitive on price. They also have a pay per TB model."

"All features are provided in the licensing. The cost of Kaminario was less than the cost of a hybrid array."

"The Kaminario setup is simple and there are no hidden licensing fees so this area is a relief."

"The "extra" costs associated with features and options that are available off the shelf with Kaminario, make their value proposition extremely competitive."

"Licensing is very straightforward. The cost was considerably lower than other products we looked at."

"The licensing is all-inclusive."

"I would like them to come down in price. It is as expensive as EMC, Hitachi, and other major vendors."

"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 is highly-priced."

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

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