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

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

"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."

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

"One of the best features is the support, which is excellent."

"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."

"The solution is very straightforward to set up."

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

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

More Pure FlashArray X NVMe pros

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

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

"The initial setup is straightforward."

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

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

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

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

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

More DDN IntelliFlash pros

"The management software is very good."

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

"Compared to Dell Unity XT, what I see as an advantage in NetApp EF-Series All Flash Arrays is the fact that it is more scalable...The performance of the product is good."

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

"The most valuable feature of this solution is its speed."

"Its performance is most valuable. This solution is much faster than other as well as older storage solutions. The performance of the system is very good. We are getting 50 times better experience than the older storages. We are using AFF 300. It also has native cloud integration and most of the features."

"We use it for our VDI environment, and have not had any complaints with it."

"The management of it is very simple. that is the most valuable feature."

More NetApp EF-Series All Flash Arrays pros

Cons

"We need better data deduplication."

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

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

"It is on the expensive side."

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

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

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

"The tool's portfolio is minimal. It is expensive."

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."

"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."

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

"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."

More DDN IntelliFlash cons

"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"

"The only major drawback is the replication between EF-Series units."

"The management interface, while very reliable, it seems a little old now and could maybe use a little modernization."

"As far as the manageability, being able to port between the two and have to do less training in-house from a customer point of view, that would be the part to improve."

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

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

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

"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."

Pricing and Cost Advice

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

"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 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."

"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."

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

"The licensing is on a yearly basis."

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

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

"Most of my customers pay for the license on a yearly basis. It can be expensive depending on the capacity number."

"Adding more capacity will increase the cost."

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

"Cheaper pricing is always good. NetApp has been doing everything the right way. They've been figuring out things really well, going in the right direction."

"They provide licenses upon purchase, so there's no need for additional licenses. Regarding additional expenses apart from the standard licensing fees, such as for support or maintenance, there aren't any. Updates take around twenty to thirty minutes, including rebooting the systems, and we haven't faced any problems with the NetApp EF-Series All Flash Arrays. We utilize various other storages like Fujitsu, IBM, and Dalian SIP, but the NetApp EF-Series stands out as we've had no issues throughout the entire year of usage."

"It's a lot cheaper than what the other vendors have for the same type of environment. It saves us money."

"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."
