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.

Good customer service and support and suitable for large environments

It is very easy to install. Users don't need to remember anything while deploying IntelliFlash because everything will be taken care of by tech support. They can easily modify the installation or change the password with the help of the tech support. It is very easy to integrate IntelliFlash with other solutions. We have plugins that can be integrated with other solutions. It will require maintenance. It is the same as any other storage solution: updates and upgrades, firmware upgrades, and drive upgrades.

Quotes from Members

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

Pros

"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."

"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."

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

"The solution is very straightforward to set up."

"I appreciate the performance."

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

"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."

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

More Pure FlashArray X NVMe pros

"It performed great originally, and when it performed great, it was awesome."

"We use IntelliFlash products for larger environments, like Qatar Airways."

"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"

"The initial setup is straightforward."

"High performance and ease-of-management are the most valuable features."

"It provides a combination of all the protocols that you need, without losing deduplication and compression."

"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."

More IBM FlashSystem pros

Cons

"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."

"One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them."

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

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

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

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

"We need better data deduplication."

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

More Pure FlashArray X NVMe cons

"It only keeps one hour of real-time data without the ability to do deep analysis of each element."

"It's somewhat scalable, but maybe not so much as some of the competition."

"In future releases, I look forward to more AI features."

"Performance is horrible now. Our original intent was to buy new storage in about two years. But since it became a critical urgency for us, we decided to purchase a new one in two or three months."

"Snapshots are not as easy to access as on a NetApp device."

"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."

"We had just one small stability problem with power flapping and it did not start up again automatically. We had to access service ports and manually restart the storage processors."

"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."

More DDN IntelliFlash cons

"We use some open-source tools for monitoring, such as Grafana and it should be bundled along with IBM FlashSystem."

"The only issue my team faced was transferring the data from the old system to IBM FlashSystem, which is an area for improvement in the solution."

"The solution is not easy to use and could improve."

"Events/log analysis tools."

"The customer's expectations are what they get on the cloud, they're expecting even in the on-premises deployments, going forward."

"The deduplication technology in IBM FlashSystem needs significant improvement."

"The interface of this solution could be improved."

"The product could be cheaper."

More IBM FlashSystem cons

Pricing and Cost Advice

"The licensing is on a yearly basis."

"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."

"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."

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

"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."

"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."

"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 Pure FlashArray X NVMe pricing and cost advice

"I think we pay around 100 grand per year for three arrays or four arrays."

"I recommend the full bundle software in order to have all the functionality. It is more expensive to purchase it one by one."

"I find the pricing of the solution to be very reasonable."

"The cost of the IBM FlashSystem is lower than the HPE solution."

"The pricing may be a bit higher than other brands. If you compare the IBM FlashSystems in midrange with Dell EMC in midrange, IBM costs a bit more, but I prefer IBM because it has more specs that I can benefit from."

"This solution is expensive compared to other solutions."

"I'd rate the basic licensing and the Virtualize software a ten out of ten, and the extra Spectrum and other an eight out of ten."

"My customers got the IBM FlashSystem bundle offer. It was a one-time purchase for three years of service. The price would depend on the storage size and could reach between $25,000 to $55,000."

"The tool is cost-efficient."

"The price of IBM FlashSystem is a little high because you pay a premium because the solution is from IBM. We had paid for the SLA prior to using the solution."
