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

"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."

"The solution is scalable."

"Overall stability is very good. It is a very stable solution."

"I appreciate the performance."

"It has good, reliable, fast storage."

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

"The solution uses newer technology for deduplication and compression."

"The solution is very straightforward to set up."

More Pure FlashArray X NVMe pros

"This solution is easy to use."

"The most valuable feature is the ability to replicate. We are running a financial company and it needs to be available 24/7. We can't afford any downtime."

"The most valuable feature is the no-forklift upgrade. While the thing is running, I can change out the controllers one at a time and keep the customer up and running. I can add shelves and storage and SSD drives or spinning drives to the system, while it's running. I can bring all that in and rebalance the load across the new disks or, if we take disks away, rebalance the load across what's remaining, and it just works."

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

"The flexibility of this solution has been valuable for our business."

"It was very easy to install, maintain, and provides excellent manageability."

"I think that Dell EMC is one of the best technical support services in Ukraine."

"The interface is easy to use which makes the product user-friendly."

More Dell SC Series pros

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

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

Cons

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

"It is on the expensive side."

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

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

"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."

"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."

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

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

More Pure FlashArray X NVMe cons

"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"

"We have seen some degraded throughput with mixed workloads. We have been working with Dell EMC to correct some of these latency issues."

"Some menus aren't so intuitive."

"It would be helpful if the solution offered higher performance, at least on the back end."

"I would like to have 100% functionality through the web app."

"The ease of use could be improved. It took me a while to learn it."

"Dell SC Series is no longer available, while Dell PowerStore, which supports NVMe over TCP, is different and not very affordable."

"Compellent comes in the form of a component that's not true of a unified storage platform."

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 support cost per array is about $20,000 a year for 24/7 support."

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

"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."

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

"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 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."

"The licensing is on a yearly basis."

More Pure FlashArray X NVMe pricing and cost advice

"The pricing of this solution is competitive."

"This solution could be better priced in comparison with other vendors."

"We have found the solution to be affordable."

"Compared to other solutions out there, it's affordable."

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

"The maintenance is usually pretty good. It's not like some of the others where they increase it in the fourth, fifth, or sixth years."

"Pricing depends on varying life cycles."

"It's absolutely affordable. Again, not having to do a forklift upgrade like some of the others have had to do in the past, it's very affordable for our customers and they continue to buy."

More Dell SC Series pricing and cost advice

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

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