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 has good, reliable, fast storage."

"The solution is very straightforward to set up."

"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."

"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."

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

"It has benefited my organization because it has reduced time to insights."

"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."

"One of the best features is the support, which is excellent."

More Pure FlashArray X NVMe pros

"Performance-wise it's high speed. It's also more stable and scalable."

"It is just as stable as any other high-end solution."

"With auto-tiering, it's easier to understand than most arrays, knowing that all of your writes go to the tier that you specify, with easy-to-create storage profiles."

"The performance benefits weren't surprising, we expected that. What we didn't expect were the densification benefits that we got out of going all-flash. We're able to put more applications on the arrays because of how all-flash performs. The way some of the application profiles have responded to all-flash has been really pleasing."

"The Dell support is helpful and the response is quick. The agents' knowledge is very good."

"I find this version to be more budget-friendly compared to products from other vendors. This aspect greatly benefits my customers. It's highly advantageous due to its affordability. The operational aspect is also noteworthy. Additionally, its availability and performance are commendable. The speaker are also equally powerful."

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

"The most valuable feature is the speed for the end-user."

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

"In the next release, I would like to see real-time analytics for further insight into consumption models."

"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."

"Adding some functions to the product would be beneficial."

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

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

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

"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."

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

More Pure FlashArray X NVMe cons

"In the future, I want any box that comes on-premises to have the provision to integrate with cloud storage."

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

"Snapshots in VMware. You can’t do snapshots since the storage itself does that. Therefore, some apps (Veeam, for example) don’t work well with this kind of tiering storage."

"The cost of the solution could be better."

"If Dell SC Series wasn't being phased out, adding an NVMe tier and secure snapshots like those on the PowerStore platform would be beneficial."

"The SC Series doesn't support NVMe storage."

"It's not very efficient anymore. There are better products out there."

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

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

"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."

"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."

"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."

"The licensing is on a yearly basis."

"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."

More Pure FlashArray X NVMe pricing and cost advice

"We have the basic license for the use of this solution and it is a permanent license. The overall cost could be less, it is expensive."

"It is one of the most cost effective systems for us. We have been able to run it longer than most, getting the most benefit and money out of it."

"The pricing of this solution is competitive."

"The pricing of Dell EMC Compellent is competitive."

"We have found the solution to be affordable."

"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."

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

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

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."
