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.

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

"The most valuable feature of this solution is reliability."

"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."

"The solution is scalable."

"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."

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

"We were able to save a ton of data center space with density ratios we've never seen before with hardware, and with Pure, we immediately saw value in the density ratios that we would be able to achieve, the performance, the scalability, and the support."

"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."

"What I really like about this program, is that it is easy to use and easy to configurate."

More Everpure FlashArray X NVMe pros

"It is consistently stable; haven't had a single issue with it."

"I think this product hits all the big features of all the SANs that are out there, all the storage vendors that are out there and more."

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

"The stability of the solution is very good."

"Built-in snapshot support gives us SAN-side functionality most other platforms would have had us license separately."

"Using snapshots allows us to automate production database refreshes to development environments in minutes, rather than in hours."

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

"So coupled with the simplicity, performance, and just absolute ease of use of the management of it, I don't know why anyone wouldn't buy it."

More Kaminario K2 [EOL] pros

"Last year, I did a DM Series installation with my colleague, and this installation was effortless because we had Lenovo support on the phone, so it was easy to get help if we had any problems."

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

"We are satisfied with the stability."

"Scalable and stable storage array."

"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 most valuable feature of Lenovo ThinkSystem DM Series is its capability to tier to the cloud, such as Microsoft Azure or Amazon AWS, and the integration is good and user-friendly."

"One of the most valuable features of Lenovo ThinkSystem DM Series is the snapshot feature."

"The price of this solution is good."

More Lenovo ThinkSystem DM Series pros

Cons

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

"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."

"The solution should improve its logon requirements."

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

"They could add more support for file storage and different types of storage."

"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."

"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."

"We've seen that when we create a POD in synchronous mode, it increases the latency."

More Everpure FlashArray X NVMe cons

"Some of the nice to haves for us, in terms of today, would be VVols but again, it’s not a critical feature."

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

"I'm hoping to see Active Directory integration. Right now, you still have to use a local admin account to log in and manage everything."

"The interface look and feel could be improved."

"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."

"Replication and de-duplication could be better."

"What I think would be a great idea for Kaminario is more visibility outside the US, when my customers start talking about AFA I notice they almost never talk about Kaminario, mainly because they just don’t know about them, and there are no local sales team to tell them about the Kaminario offering."

More Kaminario K2 [EOL] cons

"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."

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

"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."

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

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

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

More Lenovo ThinkSystem DM Series cons

Pricing and Cost Advice

"The product is expensive."

"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."

"The licensing is on a yearly basis."

"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."

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

More Everpure FlashArray X NVMe pricing and cost advice

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

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

"The licensing is all-inclusive."

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

"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."

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

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

"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."
