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.

Pros

"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."

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

"The latency is good."

"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."

"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."

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

"It has good, reliable, fast storage."

"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."

More Pure FlashArray X NVMe pros

"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."

"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."

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

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

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

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

More DDN IntelliFlash pros

"The most valuable feature is reliability."

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

"The speed, performance, and stability are the best features of IBM FlashSystem."

"The performance monitoring feature is useful as it can report in 15 minute intervals by hour, day, week, month, or by a custom date range."

"This solution is really user friendly. It also offers good performance and is highly reliable."

"At the FlashSystem level, customers are especially fond of multi-tier and distributed rate systems, particularly the dynamic rate six arrays."

"The most valuable features are, of course, the virtualization of the storage, the performance, and the compression."

"When it comes to the interface of the solution we did not encounter any challenges. Additionally, the solution has good documentation."

More IBM FlashSystem pros

Cons

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

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

"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."

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

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

"We need better data deduplication."

"There is room for improvement in the pricing of the product."

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

More Pure FlashArray X NVMe cons

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

"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."

"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."

"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."

"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

"The solution has a low number of NVME host attachments at 16 per IO group over the fiber channel."

"The array level RAID does not seem available."

"The marketing could be improved."

"They can improve its initial configuration. The initial configuration is currently very difficult. There are multiple choices or alternative ways to configure based on the use case and what you are targeting out of the device, that is, more capacity or more performance. These multiple alternatives cause a lot of confusion. They should increase the processing part of the nodes. Currently, you can cluster up to eight nodes. From my experience and the workload that I am facing in my environment currently, I would like to see either a bigger or stronger node or a larger number of nodes that can be clustered together. We formally communicated to them that we need to see either this or that, and they are working on something."

"There is room for improvement in the troubleshooting part, specifically related to IBM Spectrum for Insight. Customers are uncomfortable with remote access, which affects automated remote support."

"The pricing could be improved, but I think it's getting better and better with each version. IBM needs to implement NAS storage again, as this is a big flaw. Dell EMC is very good at this and if you compared them based on NAS storage, Dell EMC would win right away. IBM's solution for NAS storage is very complicated. We don't have a storage box that provides file sharing from itself, we have to put software on it and go through a whole complicated process. It should be simplified."

"The technical support in my region is satisfactory but it could improve. Support is very important for customers and downtime is very critical for us. We would like onsite or complete technical support which can help us to minimize our downtime or if problems occur."

"Cloud file sharing is an area that needs improvement."

Pricing and Cost Advice

"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."

"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."

"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."

"The product is expensive."

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

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

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

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

More Pure FlashArray X NVMe pricing and cost advice

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

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

"This solution is expensive compared to other solutions."

"The price is a little bit high so is rated a six out of ten."

"IBM V7000 has a new license and price structure which provides intuitive licensing based on the functions customers wish to enable and use the most."

"Overall the price of the solution is expensive and this includes the license."

"Its price is very good."

"Pricing can be considered as per market competition."

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

"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."
