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

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

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

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

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

"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."

"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."

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

"The solution is very straightforward to set up."

More Pure FlashArray X NVMe pros

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

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

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

"The initial setup is straightforward."

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

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

"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 initial setup is straightforward and can be done in an hour and a half by one person."

"Speed (IOPS/second) – It is most vital for applications that need low latency and high speed for transferring the data."

"The GUI is very easy and performance is also good."

"IBM FlashSystem is a flexible solution with plenty of features."

"This solution is very stable."

"The speed and the ease of installation are the most valuable features."

"IBM FlashSystem has been stable in our operations."

"The FlashSystem 900 consistently delivers performance below 1ms for read/write. This performance is essential for an effective SVC stretch-cluster configuration across two datacenters, and presenting active-active storage to the customer."

More IBM FlashSystem pros

Cons

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

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

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

"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."

"I would like to see some AI features that would allow arrays to intelligently identify threats or unusual behavior in the data pattern and give an alert."

"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."

"It is on the expensive side."

"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."

More Pure FlashArray X NVMe cons

"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."

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

"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."

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

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

"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."

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

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

More DDN IntelliFlash cons

"Include an option to upload the support package to the IBM ECuRep when opening an IBM PMR."

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

"Our customers have raised concerns about the limitations of the FlashSystem 5200 and 7300, which only offer a 32-gigabyte connection."

"The GUI needs some improvement."

"The support could improve by allowing you to speak to someone when you call rather than them calling you back. However, once we do have contact with one of their technicians they are excellent."

"I would like to see an improvement in the handling of large amounts of rights."

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

"The ease of installation should be improved. We had issues with the configuration model."

More IBM FlashSystem cons

Pricing and Cost Advice

"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."

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

"The product is expensive."

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

"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."

"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."

"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."

"The solution requires a license and could be less expensive."

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

"I price of IBM FlashSystem is reasonable and competitive."

"The integration is already included in the license cost of IBM FlashSystem. The integration is very easy. You get the IBM storage core with all software, firmware, and upgrades. EMC provides the features in the box, but they are not free for customers. There is a licensing cost for features. We have yearly licensing, but IBM has also provided a new option where you pay as you go. They provide a big box, and I pay, for example, for 10 terabytes. If I exceed 10 terabytes, IBM will charge for the new storage after 10 terabytes. It is a good opportunity in the market for using the storage as a cloud and paying as you go."

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

"This solution is expensive compared to other solutions."

"The pricing has been very competitive for the last few years. IBM got to the point where they changed the pricing model and we feel very comfortable with the pricing. It's very competitive. Over the last two years, IBM has been coming up with all kinds of interesting promos, especially for the SMB systems. That makes it very competitive price-wise and in terms of performance..."

"Pricing can be considered as per market competition."
