Eugene Hemphill - PeerSpot reviewer
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.
Anil Rahulwar - PeerSpot reviewer
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.
Syed Habib - PeerSpot reviewer
Efficient data replication and fast IOPS have improved operational performance
Dell and a partner jointly implemented this solution in Auvink. We installed the Flash, which makes our IO operations fast and efficient. Replication is available, allowing us to replicate data simultaneously from one site to another. All-flash technology and vTXT enhance speed, and the IOPS are faster. The cache's IOPS are much better. Snapshots provide a unique feature for testing and make management more comfortable and easy. The platform is multi-supported and certification is more convenient and easy to manage.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."
"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."
"The high availability of the product is the most valuable feature."
"I appreciate the performance."
"We are satisfied with the performance as it is significantly faster compared to traditional storage options."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"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."
"The database workloads are pretty fast because I frequently move data from here to there."
"Data Compression: Up to 80% space reduction in the database"
"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"We use IntelliFlash products for larger environments, like Qatar Airways."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"High performance and ease-of-management are the most valuable features."
"It performed great originally, and when it performed great, it was awesome."
"The initial setup is straightforward."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"We run about 100 virtual servers on it. We have about 100 users accessing the file shares from there, and I've seen no problem with that. We have about a 10GB backbone. Whatever we throw at it, it hasn't shown any sign of weakness or anything. It's been really good."
"The most valuable aspects of this solution are its stability, performance, and ease of updating."
"Their support cases are all handed through the portal. The support contacts me when they need to do upgrades. It has been great. It's all very well-handled, scheduled, and performed."
"The setup and installation procedures are easy."
"It's easy to handle for administrators and it's a unified system. It's not as complex as Celerra systems or CX4 Clariions to administrate. You can do everything with one GUI."
"I don't think I've ever seen latencies above 10 milliseconds unless it was something that wasn't the array that was messing up. The thing is rock-solid."
"It is simple to use and easy to manage. We don't touch it after we set it up."
"It's easy to manage. We access it and manage it through Unisphere and have had no issues. We're able to provision storage, create consistency groups, create RDMs for our virtual machines. Creating it through Unisphere, it automatically adds the data store on the VMware side and rescans the LUNS. We just have to add and configure the storage in one place and it takes care of everything, which is very handy."
 

Cons

"I'd like to see the product implement active replication for vehicles such as VMware."
"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."
"I would like to see replication and DR features in the next release of this solution."
"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."
"The UI for this solution needs to be improved."
"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"Snapshots are not as easy to access as on a NetApp device."
"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."
"It's somewhat scalable, but maybe not so much as some of the competition."
"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 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."
"You can't use every feature, because it costs in performance. Therefore, you have to choose which features to use to achieve a better environment. That is why customers do not use every feature in Unity."
"We integrated it with vSphere but that integration was "iffy". It was okay but we had a few challenges with it."
"It is missing some features, like deduplication."
"We noticed in the last release of code that there were some inefficiencies around getting our data efficiency up in terms of dedupe and compression."
"In future releases, I would like to see automatic upgrades from one to the next, when this system is coming out and the next one is coming in; more akin to what Pure Storage is doing. That would be really helpful."
"This is a tier-three solution and it gives us what we need for archiving and backups."
"The one thing that we would look at would be if they were to expand the file level features, just to give us a balance or a tier between it and Isilon options out there, for unstructured data."
"We would like to see the concept of Storage Groups brought back to this product line."
 

Pricing and Cost Advice

"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."
"We pay approximately $50,000 USD per year in licensing fees."
"The support cost per array is about $20,000 a year for 24/7 support."
"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."
"Given its price, Pure is not the first option."
"As far as the licensing costs, everything is included in the license."
"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."
"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 return on the investment was simply speeding up our entire vSphere stack, which allowed our developers and engineers to get their workloads done faster and simpler. We were experiencing VM snapshot times of 45 minutes to two or three hours, and it shrunk it down to under five minutes."
"While Dell EMC is costly, I don't have any complaints about their licensing model."
"The pricing is reasonable. We're using the Flex on Demand pricing. It's really good for us when we pay for what we use. It made it easy to get it inside since it's an OpEx and instead of CapEx expense."
"This solution is a good price for what you get."
"This solution offers great pricing."
"This unit is one of the cheapest storage all-flash arrays in the market and it does well for what it is intended. It can be combined for both file and block storage."
"Obtaining a warranty is easy."
"One of the most valuable features is its cost. It was inexpensive compared to other arrays that we were looking at."
