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

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

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

"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."

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

"The solution is scalable."

"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."

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

More Pure FlashArray X NVMe pros

"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."

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

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

"The initial setup is straightforward."

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

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

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

More DDN IntelliFlash pros

"The maintenance service and support from IBM is very good."

"The performance of IBM FlashSystem is very good. The new technology and high throughput have given us more confidence in the solution. The management of the system has improved and we can control the monitoring system alerts and multiple FlashSystems with the Enterprise Cloud Edition, which is free. The migration of recently stored data to a new flash is much easier. You can move your data because you can utilize it externally."

"Flash disk with Easy Tier option"

"The initial customer technical support was efficient and effective."

"IBM's technical support do excellent work."

"Installing FlashSystem is very easy. It takes less than half an hour, and I can handle it all myself."

"One of the valuable features is the performance, it is one of the best in the market."

"It's a mature product. It's like a BMW that evolves consistently."

More IBM FlashSystem pros

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."

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

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

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

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

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

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

"In the future, I would like to see integration with enterprise backup systems."

More Pure FlashArray X NVMe cons

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

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

"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."

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

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

"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."

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

More DDN IntelliFlash cons

"They don't offer subscription-based payments."

"The price is very costly."

"In the next release having the next level of high-speed performance would be great."

"The interface could improve in IBM FlashSystem."

"Additional licenses might be added for the fundamental licenses, such as those for copying and flash copies."

"The GUI needs some improvement. An additional function that could be helpful is reducing the time it takes to delete volumes, especially if they are compressed or deduplicated."

"There is room for improvement in the troubleshooting part, specifically related to IBM Spectrum for Insight."

"One area for improvement is in the GUI, where host clusters are not properly dealt with. With Hypervisor host clusters, all hosts must see the same volumes in the same order. Using the concept of a “host-group” has been around (even with IBM) for many years, so why not with the V7000?"

Pricing and Cost Advice

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

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

"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 product is expensive."

"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."

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

"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."

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."

"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."

"Its price is very good."

"It pays to go back and get the best price you can from your supplier. The first offer is not always at the best discount."

"The price depends of the technology that our customers need. The price can come at a lower cost but this may increase as storage is added."

"This is an expensive product and if the price were reduced it would be better."

"The price of IBM FlashSystem is reasonable."

"The pricing is reasonable."

"Regarding licensing make sure you add at least three years software maintenance from IBM at the beginning, because you will not be able to download firmware updates or any fixes/patches without this."
