Chief Technology Officer at Lambda256

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.

Offers flexibility and top-notch technology

You can go to bed peacefully if you have a NetApp. If you have NetApp within your data center, you get to know about power failure if you are using it. Your NetApp will still come alive. Even if it does not come alive, I can say that it is not like other tools when it comes to dealing with power failure. The tool is affordable, and the technology is top-notch. It is the only technology that has software for what we call inline compression and deduplication. All the products under NetApp are aiming to use AI. I know that you can achieve whatever you want to do with NetApp EF-Series All Flash Arrays. I rate the tool a nine out of ten.

Quotes from Members

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

Pros

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

"The high availability of the product is the most valuable feature."

"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."

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

"Technical support has been helpful and responsive."

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

"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."

"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."

More Pure FlashArray X NVMe pros

"The initial setup is straightforward."

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

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

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

"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."

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

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

More DDN IntelliFlash pros

"The management software is very good."

"The main advantage of this solution is performance."

"The product's initial setup phase can be managed easily and completed in 20 to 30 minutes. It is one of the fastest storage tools that you can implement."

"The hardware and software of NetApp EF-Series All Flash Arrays are easy for us to use."

"Rapid deployment, easy integration management and cloning of areas."

"The speed is the most valuable feature."

"The most valuable feature is the ability to set a specific margin of performance to a specific workload."

"This storage solution is both stable and scalable, and it works for our needs."

More NetApp EF-Series All Flash Arrays pros

Cons

"Maybe the price can be reduced since the solution is very expensive."

"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."

"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."

"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."

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

"It is on the expensive side."

"The software layer has to improve."

"Adding some functions to the product would be beneficial."

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

"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."

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

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

"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."

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

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

More DDN IntelliFlash cons

"A little more manageability, a simpler management interface. It's not necessarily that it's way overly complex. It's just that it's not as easy as the FAS series."

"We need a center related to NetApp in Egypt so that we can deal with them directly."

"There could be an improvement when it comes to SLA support, it could be faster."

"I’d like to see bigger, faster, better hardware, of course. I think that is the way the hardware is trending anyway; bigger, faster CPU, better software, fewer bugs, all that stuff. T"

"Its pricing should be better. Its price is competitive, but they need to improve the pricing. They have different licensing models, which they need to improve. My expectation was cloud integration, which they have, but it is a different license. Therefore, people cannot enjoy it. If I want to use it, I need to pay extra. There is a cost involved for everything, but it should reach everyone. It is similar to having a Rolls-Royce, but you need to pay extra for the key. If you want the key, you need to pay."

"This solution has limited storage."

"Better integration with other brands is important so we would like to see it easier to integrate."

"They could improve overall scalability through performance. Denser capacity, which is doable, it is what the competition is doing."

Pricing and Cost Advice

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

"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."

"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."

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

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

"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."

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

"The licensing is on a yearly basis."

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."

"One has to opt for a perpetual-based licensing model for one year or three years. After three years, you need to renew the license."

"Price-wise, NetApp EF-Series All Flash Arrays is costlier than Dell. You have to buy a lot of licenses separately."

"Its cost-effectiveness is a major selling point. Compared to other storage vendors, the EF-Series offers excellent value for its price. It's truly a leading product in the industry."

"They need to improve its pricing. The storage market is dying. So, they need to improve the price because it should reach all people. NetApp is one of the top ones, and they are charging a little bit of royalty as compared to other storage solutions."

"The pricing of this solution is competitive with other vendors here in Egypt."

"NetApp EF-Series All Flash Arrays is an expensive product."

"The pricing of the solution is expensive, considering the initial investment required...At the end of the product's life cycle, it could get cheaper, but the initial investment in NetApp makes it one of the most expensive solutions."

"It's a way to get relatively low-cost, very high-performance, low-latency block storage as a point solution."
