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

"The tool's valuable features are speed, security, data compression, and reliability. Its data compression feature is the best that we have ever seen. It helps us to save money and resources."

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

"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 most valuable feature of this solution is reliability."

"We are satisfied with the performance as it is significantly faster compared to traditional storage options."

"It has benefited my organization because it has reduced time to insights."

"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."

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

More Everpure FlashArray X NVMe pros

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

"Ease of Use: Someone can learn it in only few hours Performance: Easy Tier is doing miracles Data Compression: Up to 80% space reduction in the database"

"We have been able to realize storage space savings for our virtualization environment and it has reduced our electricity usage by reducing the number of disks needed for the virtual environment."

"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks Cheaper than pure solid state without needing to actively manage where the data is located."

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

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

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

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

More DDN IntelliFlash pros

"We are a 100% satisfied with the stability of the solution."

"Our automatic banking systems have become twice as quick with flash storage."

"The most crucial feature of IBM FlashSystem is compression."

"We've found the solution to be very stable so far."

"This product is so easy to use."

"Ability to manage third-party arrays and virtualise them: One screen to control multiple arrays. Simplified administration."

"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."

"The most valuable features were the performance of the array, i.e., very low latency and high IOPS, plus the management interface is very easy to use."

More IBM FlashSystem pros

Cons

"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."

"The software layer has to improve."

"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."

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

"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."

"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."

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

More Everpure FlashArray X NVMe cons

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

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

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

"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 annoying that if you turn on SMB3 (as opposed to the earlier CIFS protocol), then it is not possible to access a file store using a mixture of SMB and NFS."

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

"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."

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

More DDN IntelliFlash cons

"The array level RAID does not seem available."

"AHV is Acropolis Hypervisor – A relatively new Hypervisor, robust and stable as VMware vSphere, has built-in advanced analytics and powerful operations, Self Service Portal and components for DevOps included, managed by a single pane of glass (Prism) via HTML5 and it is free of charge – That is why Nutanix is so advanced and revolutionary."

"I would like to have a larger disk. Right now, you can get 57 terabytes in a shelf."

"Their technical support needs improvement in terms of reachability for the clients and response times. They should be more responsive and have more online platforms for support. They should make more technical information available online. There could be some kind of documentation community."

"I would like to see bigger modules."

"It doesn't scale out that well."

"I think the only thing the developers can look at, is that it is limited to 25 gigabytes currently. In the next release they might want to increase that."

"Replication features need improvement. Currently, they are there in the product, but I'm not sure as to how it works exactly."

Pricing and Cost Advice

"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."

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

"The licensing is on a yearly basis."

"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."

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

"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."

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

More Everpure 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."

"If five is a good price and one is a high price, I would rate the price a two or three out of five."

"The pricing is reasonable."

"I would rate the pricing of this solution a four out of five."

"The solution has good pricing, but it is not cheaper."

"Pricing can be considered as per market competition."

"For a yearly license, it is about $100,000. There are no additional costs. The entire system is included."

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

"There are no licensing fees, it is a one-time purchase of the IBM FlashSystem."
