Helps to save money and resources with the data compression feature

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. One way to improve the product is to add an operational assistant that doesn't depend on VMware. It could also establish more alliances with other operational systems.

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.

Cons

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

"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."

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

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

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

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

"In terms of what needs improvement, the dashboard and management could be simplified."

"It is on the expensive side."

More Pure FlashArray X NVMe cons

"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 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."

"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."

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

"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."

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

More DDN IntelliFlash cons

"I would like to see higher-capacity drives, as they come out; I have heard that 15 TB are out on a different NetApp series. Getting those on the EFs would be nice."

"It needs a better management tool."

"I would like to shrink it more, if we can. The smaller, the better."

"We have used IBM previously. We found that the storage from IBM was poor and we chose NetApp EF-Series All Flash Arrays because it can scale very easily."

"The solution's technical support is not as good as it is supposed to be since you have to push them to get support."

"This solution does not have any compression or deduplication."

"NetApp could improve the speed of the rebuilding rate."

"Their problems are on the software and the controlling of the storage where they lack segmentation and federation."

Pricing and Cost Advice

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

"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."

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

"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."

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

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

"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."

"The product is expensive."

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 not available to many users because the cost is very expensive."

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

"The cost of our license is approximately $200,000 over three years for NetApp EF-Series All Flash Arrays. There can be additional costs for storage. For example, if you want to have eight terabytes."

"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."

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

"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."

"he price point that we're getting is very competitive in the market. Since we are buying in such a large quantity, they gave us a huge discount."

"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."
