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.

Pros

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

"The latency is good."

"On a scale of one to ten, I rate Pure FlashArray as ten."

"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."

"I appreciate the performance."

"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."

"The solution is scalable."

"The initial setup was extremely simple and straightforward."

More Pure FlashArray X NVMe pros

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

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

"The initial setup is straightforward."

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

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

More DDN IntelliFlash pros

"The most valuable feature is that is supports a high IOPS rate."

More IBM FlashSystem pros

Cons

"It is on the expensive side."

"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."

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

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

"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."

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

"We would like to see VNC integration or be able to use Pure Storage with VNC."

"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."

More Pure FlashArray X NVMe cons

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

"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."

"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."

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

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

"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."

More DDN IntelliFlash cons

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

"They don't offer subscription-based payments."

"Cloud file sharing is an area that needs improvement."

"The array level RAID does not seem available."

"The price is very costly."

"There could be some extra features added."

"This solution could be improved by offering greater amounts of storage."

"In IBM FlashSystem, data reduction is an area with shortcomings where improvements can be made in the future."

More IBM FlashSystem cons

Pricing and Cost Advice

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

"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."

"With VMware, we pay $300,000 annually."

"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."

"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."

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

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."

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

"Among IBM, Dell EMC, and Pure Storage, IBM is the cheapest. The price is also based on our location, the size of our entity, and our regular annual purchases from them. We are a very big IBM customer, so we normally get very high discounts. We are not a big customer of Pure Storage. We don't buy that much from Pure Storage per year. Everything is included in the price. There is no extra license for different functions."

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

"This is an expensive product and if the price were reduced it would be better."

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

"Regarding licensing make sure you add at least three years software maintenance from IBM at the beginning, because you will not be able to download firmware updates or any fixes/patches without this."

"The pricing is competitive in our country."

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

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

IBM FlashSystem products are enterprise computer data storage systems that store data on flash memory chips. Unlike storage systems that use standard solid-state drives, IBM FlashSystem products incorporate custom hardware based on technology from the 2012 acquisition of Texas Memory Systems. This hardware provides performance, reliability, and efficiency benefits versus competitive offerings.
