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.

Offers flexibility and top-notch technology

You can go to bed peacefully if you have a NetApp. If you have NetApp within your data center, you get to know about power failure if you are using it. Your NetApp will still come alive. Even if it does not come alive, I can say that it is not like other tools when it comes to dealing with power failure. The tool is affordable, and the technology is top-notch. It is the only technology that has software for what we call inline compression and deduplication. All the products under NetApp are aiming to use AI. I know that you can achieve whatever you want to do with NetApp EF-Series All Flash Arrays. I rate the tool a nine out of ten.

Quotes from Members

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

Pros

"The database workloads are pretty fast because I frequently move data from here to there."

"The tool's valuable features are speed, security, data compression, and reliability. Its data compression feature is the best that we have ever seen. It helps us to save money and resources."

"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."

"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."

"The latency is good."

"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."

"The most valuable feature of this solution is its ease of use."

"It has good, reliable, fast storage."

More Pure FlashArray X NVMe pros

Cons

"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."

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

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

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

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

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

"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."

"Maybe the price can be reduced since the solution is very expensive."

More Pure FlashArray X NVMe cons

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

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

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

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

"This is an expensive solution."

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

"The Lenovo ThinkSystem DM Series was very hard to configure. Installation of the product was very hard. These are its areas for improvement."

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

More Lenovo ThinkSystem DM Series cons

"We have used IBM previously. We found that the storage from IBM was poor and we chose NetApp EF-Series All Flash Arrays because it can scale very easily."

"Their problems are on the software and the controlling of the storage where they lack segmentation and federation."

"The solution's technical support is not as good as it is supposed to be since you have to push them to get support."

"It was difficult to implement and lacks some additional features that would be useful, but as a solution fits a particular need for our organization."

"There could be better integration with some of our Cisco products."

"The initial setup phase of NetApp EF-Series All Flash Arrays is not straightforward and needs improvement."

"I've observed an issue when creating a new storage solution with NetApp EF-Series All Flash Arrays."

"The price of the All Flash solution is very high."

Pricing and Cost Advice

"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."

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

"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."

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

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

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

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

More Pure FlashArray X NVMe 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."

"The pricing of the solution is expensive, considering the initial investment required...At the end of the product's life cycle, it could get cheaper, but the initial investment in NetApp makes it one of the most expensive solutions."

"Cheaper pricing is always good. NetApp has been doing everything the right way. They've been figuring out things really well, going in the right direction."

"Its cost-effectiveness is a major selling point. Compared to other storage vendors, the EF-Series offers excellent value for its price. It's truly a leading product in the industry."

"Price-wise, NetApp EF-Series All Flash Arrays is costlier than Dell. You have to buy a lot of licenses separately."

"One has to opt for a perpetual-based licensing model for one year or three years. After three years, you need to renew the license."

"The price point for EF is considerably lower than the alternatives."

"The pricing is comparable with other competitors and similar in mid-range solutions, and for high range solutions, it would depend on our requirements or needs."

"The pricing of this solution is competitive with other vendors here in Egypt."
