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.

User interface offers clarity and detailed information while technical support consistently delivers

The best features of Dell SC Series are stability and replication. The replication solution is excellent, and they have a solution named Live Migration. It is a robust platform. The interface and the GUI (graphical user interface) for administrating the Compellent are exceptional, with abundant information that is very clear. The management capabilities are excellent, and the stability of our storage hardware is remarkable.

Stability-wise, a device that has been up and running for years

The failover capability and resiliency are some of the solution's valuable features. The big thing is resilience because it has richer coding in it, so multiple devices can't fail. Also, one can still access a number of CBoxes that can allow one to access their file system. Once a device fails, it fails the transparency of the end-user, and it just starts using another resource. The encryption capability, the snapshots, along with a whole bunch of features make the tool valuable. VAST Data keeps adding more and more features all the time.

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 this solution are its ease of use and performance."

"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."

"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."

"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 most valuable feature of this solution is reliability."

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

"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."

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

More Pure FlashArray X NVMe pros

"It is fast and performs well."

"The solution has a wide variety of valuable features. The data progression works well. We use the snapshot functionality quite a bit and really like it."

"Dell SC Series offers a lot of performance, being one of the best performing storages Dell ever made."

"The product offers good performance and is quite powerful."

"We see very low latency with very high IOPS for mixed workloads."

"What is most valuable about the Dell EMC SC Series system was its reliability."

"The setup and installation is much simpler now, because Dell has standardized the configure process."

"One time, we had a drive fail and we were notified before we even saw it on the device."

More Dell SC Series pros

"This has been one of the most reliable storage systems that I have ever used."

"The solution is useful for machine learning and scientific applications, including computer simulations."

Cons

"It feels more suitable for small and medium-sized businesses rather than enterprises."

"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."

"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."

"We've seen that when we create a POD in synchronous mode, it increases the latency."

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

"There is room for improvement in the pricing of the product."

"I would like to see some AI features that would allow arrays to intelligently identify threats or unusual behavior in the data pattern and give an alert."

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

More Pure FlashArray X NVMe cons

"I would like to see an integrated key manager in the controllers. Currently, it's an external product. It would be nice to have the option of having a built-in key for self-encrypting drive features."

"While the price is competitive, in the next release it would be better if they could reduce the fees."

"I would like to improve the processing ability."

"If Dell SC Series could have supported the protocol NVMe over TCP, that would have been great. It does not."

"While the scalability is good, there are certain limitations."

"Licensing, especially on the storage line, could use some simplification. It's not terrible, but, for example, with the Isilon series, they've gone to completely a la carte. A la carte is very difficult to traverse, as to what you need. It would be more beneficial, at least from my point of view as a customer, if they did it more like car companies do, where there are package lines"

"Some menus aren't so intuitive."

"The configuration could be easier in Dell EMC SC Series."

More Dell SC Series cons

"The read/write ratio is an area in the solution with some flaws and needs improvement."

"The write performance could be improved because it is less than half of the read performance."

Pricing and Cost Advice

"The licensing is on a yearly basis."

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

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

"The product is expensive."

"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."

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

"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."

More Pure FlashArray X NVMe pricing and cost advice

"We have found it to be affordable. Comparing the cost with other hardware, it seems to be right in line with the compute and the storage that we get with it."

"Always keep in mind, this is not just a enclosure with disks is a complete SAN as a service. There is software, license, and storage in one single solution."

"It has a good price point and offers some value-added enterprise features."

"Pricing depends on varying life cycles."

"We have found the solution to be affordable."

"The pricing of Dell EMC Compellent is competitive."

"It's a very affordable solution."

"This product is too expensive compared to others, and I don't see any value in using it."

More Dell SC Series pricing and cost advice

"We acquired VAST Data as a one-time, capital purchase."

"Price-wise, VAST Data is not the cheapest, not the most expensive one."
