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

"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."

"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."

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

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

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

"The initial setup was extremely simple and straightforward."

"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."

"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 Pure FlashArray X NVMe pros

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

"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."

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

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

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

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

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

More DDN IntelliFlash pros

"We have been working with the solution for around a year and so far it has shown itself to be stable."

"Its initial setup process is easy."

"I would rate the stability of Lenovo ThinkSystem DE Series as a ten."

"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions. It's also easy to use."

"The most valuable features of the Lenovo ThinkSystem DE Series are the dual controllers, available installation documentation, and the option of multiple host bus adapter interfaces."

"The solution is very easy to set up."

"This solution is good for virtualization and meets the need for CPU and RAM requirements."

"Lenovo ThinkSystem DE Series is highly reliable, especially for block-level storage. It is stable, with minimal downtime and no issues beyond user errors."

More Lenovo ThinkSystem DE Series pros

Cons

"The software layer has to improve."

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

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

"It is on the expensive side."

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

"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."

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

"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."

More Pure FlashArray X NVMe cons

"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."

"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."

"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."

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

"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."

More DDN IntelliFlash cons

"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration. I don't know if there is room for a more hyper-conversion structure to work with, but this would be easier."

"The type of connection that is used in Lenovo ThinkSystem DE Series should be improved."

"There could be a snapshot feature in the solution."

"In the next release, I would like to see more functionality. But, again, it is an entry-level product."

"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."

"In the next release, I would like to see support for Hyper-converged infrastructure."

"The features are limited."

"The product could support advanced software integrations."

Pricing and Cost Advice

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

"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."

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

"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."

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

"The licensing is on a yearly basis."

"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."

"The solution's price could be better."

"For an all-flash setup, the cost is around $20,000 for a decent configuration."

"We have a five-year contract for providing support."

"The pricing for this solution is good compared to HP or Dell EMC."

"It is an expensive solution."

"The pricing is fair and low compared to other products in this category."

"All of the features are bundled together, and you can renew the bundle with all of the features included."

"The best thing about this solution is its price, which reduces our costs."

ThinkSystem DE Series

Overview

Pure Storage FlashArray//X is the world’s first enterprise-class, all-NVMe flash storage array. It represents a new class of storage – shared accelerated storage, which is a term coined by Gartner – that delivers major breakthroughs in performance, simplicity, and consolidation.

Pure Storage

Western Digital through its IntelliFlash arrays delivers high-performance storage with a complete range of features and connectivity options, including inline compression and deduplication, application and VM consistent snapshots, replication, RAID, data encryption, VMware vCenter integration, and multi-protocol support for SAN (FC, iSCSI) and NAS (NFS, SMBv3). IntelliFlash arrays deliver high availability through dualredundant and hot-swappable components, active/active or active/passive controllers, non-disruptive software upgrades, eMLC flash, and proactive cloud-based monitoring, analytics, and intelligence. A RESTful API provides scripted or programmatic control.

DataDirect Networks

The DE All-Flash Series delivers the performance of more than 2,000 15k rpm HDDs, yet requires only 2% of the rack space, power, and cooling. Because it consumes 98% less space and power, DE Series can significantly improve the overall efficiency of your IT operations while continuing to meet your performance requirements.
