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.

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.

Quotes from Members

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

Pros

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

"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."

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

"Data Compression: Up to 80% space reduction in the database"

"The initial setup is straightforward."

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

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

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

More DDN IntelliFlash pros

"Overall stability is very good. It is a very stable solution."

"The latency is good."

"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 system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."

"The solution uses newer technology for deduplication and compression."

"Technical support has been helpful and responsive."

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

"The most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."

Cons

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

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

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

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

"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."

"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."

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

"In the proxy section you can’t choose a user account and password, so it is not allowed at the moment to go out, if customer has such constellation."

More DDN IntelliFlash cons

"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."

"We need better data deduplication."

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

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

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

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

"It feels more suitable for small and medium-sized businesses rather than enterprises."

"There are some challenges with data encryption and reduction."

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."

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

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

"The licensing is on a yearly basis."

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

"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."

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

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

"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."
