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.

Resilience has supported proactive management and secured audit readiness across multiple sites

The resilience in Dell PowerStore benefits my company from an auditing perspective because we know we have that resilience in place. I see Dell PowerStore playing a bigger role in the future because we are starting to use it more, and that is pushing it. The biggest return on investment for me when using Dell PowerStore is scalability. Scalability is key. I can amplify that scalability is the biggest return on investment because we have redundancy between two sites; if something goes down, we have to manage it, but we want to do it proactively.

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

"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."

"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."

"The most valuable feature of this solution is its ease of use."

"Technical support has been helpful and responsive."

"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."

"It has good, reliable, fast storage."

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

"The best features of Pure FlashArray X NVMe include the volume snapshot capabilities, which allow us to save most of the storage space by volume snapshots periodically."

More Pure FlashArray X NVMe pros

"Pricing is very good. It's very competitive against those of all the others that I looked at in the marketplace, such as Hitachi, IBM, HP, and Pure. Dell is right there in the mix as far as providing the best price point as well as meeting the performance requirements that we have."

"The management console of Dell PowerStore is very easy to navigate through, and there have been no problems accessing it in any of the common browsers used, including Chrome, Firefox, and Edge, making configurations easier because everything is visible in plain sight through a graphical interface."

"Dell EMC PowerStore is scalable."

"Has a great mapping feature."

"Dell PowerStore improves my organization in general as we are more confident regarding DRP tests and regulations that require us to have a DRP plan."

"The solution is stable."

"Dell PowerStore runs effectively, and we have not had any stability or reliability problems to my knowledge."

"The solution's migration feature is very valuable, but the most valuable thing is that more features appear with every iteration of the software."

More Dell PowerStore 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

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

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

"They could add more support for file storage and different types of storage."

"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."

"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."

"In the future, I would like to see integration with enterprise backup systems."

"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."

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

More Pure FlashArray X NVMe cons

"The interface of Dell PowerStore reminds me of the Cisco mentality where it's just boxes moving around as you're clicking; it's not easy to understand what you're trying to do, and you have to have solid documentation to navigate the system and make changes to ensure you're not jeopardizing your system as you present and remove storage and expand LUNs."

"Even though most customers have four-hour support, it sometimes takes two days for parts to arrive when I would expect it the next day."

"Dell PowerStore is a good solution overall, but some models could support hypervisors better by allowing for more customization and flexibility for customer needs."

"Dell PowerStore is a very expensive storage solution. That said, the speed for recovering information is amazing. I would make the product cheaper. The discounts from Dell to South America are not sufficient because we need better pricing. The discounts for small PowerStores are not enough to close deals since I'm a distributor. As both a user and seller, it's challenging to sell Dell PowerStore to the channel or final customers because we don't have enough discount from Dell."

"I would have preferred if Dell PowerStore could have a common operating system across all their products, as that would be of great advantage."

"Horizontal scaling has room for improvement."

"We question that quite often because they have been increased by thirty to thirty-five percent every quarter for unexplained reasons, and that definitely does not go down well with customers."

"The data resiliency and cybersecurity features of Dell PowerStore are just normal and would be considered medium; we need additional components such as cybersecurity vault for increased resilience."

More Dell PowerStore cons

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

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

Pricing and Cost Advice

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

"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."

"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."

"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."

"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."

More Pure FlashArray X NVMe pricing and cost advice

"The solution’s pricing is always too high."

"PowerStore's pricing is reasonable."

"The price is not cheap, but it's worth it for the features you get from the storage. If you can afford it, you are probably buying the best solution that you can have for this virtual environment."

"The rate is always too high. Nobody likes paying for it. I have not seen a client yet who says that the price should be higher. Initially, people look at it, but when they see what the benefits are, it is a no-brainer. We can give them good pricing at the outset."

"It is easy to work with Dell from the licensing perspective."

"Dell PowerStore is more expensive than Dell EMC Unity All Flash. Dell PowerStore's performance metrics were way higher than what Dell EMC Unity All Flash offered."

"We purchased it with a five-year warranty."

"Dell PowerStore is affordable and the license is just a face license which is great."

More Dell PowerStore 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."
