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

"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."

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

"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."

"The most valuable feature of this solution is reliability."

"The initial setup was extremely simple and straightforward."

"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."

"The most valuable features of this solution are its ease of use and performance."

More Pure FlashArray X NVMe pros

"The simplicity and ease of use have been very valuable features. I have a very small team, and only half of the team is well versed in the HP product. Whereas if I bring PowerStore in, everyone can learn it because it will be new on the floor."

"The resilience in Dell PowerStore benefits my company from an auditing perspective because we know we have that resilience in place."

"Dell PowerStore has benefited our organization through cost savings."

"The return on investment since switching to Dell PowerStore has been really good."

"We used Cloud IQ. The central management and outside support functionality were great since we had systems all over the world."

"It has its own file formatting protocol, which saves a lot of space."

"Moving and optimizing workloads within the cluster is quite easy based on my experience with Dell PowerStore."

"The most valuable features of Dell PowerStore are the support for NVMe and SCM, which provides end-to-end performance and high IOPS, minimizing latency. It is a full-fledged storage solution."

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

"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."

"We need better data deduplication."

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

"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."

"The software layer has to improve."

"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."

"The tool's pricing is higher than competitors."

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

More Pure FlashArray X NVMe cons

"What would make it perfect is addressing the occasional lack of continuity with consultants who are on projects for five to six weeks regarding Dell PowerStore."

"Improvements could be made in the replication solutions of Dell PowerStore. Even though replication between Dell PowerStores is possible, high latency connectivity is problematic."

"We would consider this solution if the pricing is competitive with other options, as it offers a very good solution. However, the current price is slightly higher than the competition."

"Dell PowerStore has just caught up to some of the competition by introducing METRO nodes a few months ago while the competition has had the feature for years."

"The management UI is pretty decent and gets the job done, but the upgrade process is challenging."

"In terms of improving Dell PowerStore, they should have simplified documents available for customers, not just for the support team."

"If I could improve Dell PowerStore, I would suggest that integrations into backup platforms be a little more streamlined."

"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."

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

"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."

"With VMware, we pay $300,000 annually."

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

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

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

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

"The product is expensive."

More Pure FlashArray X NVMe pricing and cost advice

"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."

"HCL Tech has a TLA with Dell, so in terms of price point, we are very competitive. Based on my experience, the cost of Dell PowerStore for around 500 GB of capacity is very competitive compared to any other platform in the market."

"The solution is expensive."

"The price is high compared to the Tunisian market."

"The solution's price was comparable to other products for the use case, size, and setup."

"The pricing structure and licensing model of Dell PowerStore are very good and I like it. We chose it because it was reasonably priced and met our requirements"

"With compression, we were able to have a solution within our company's budget. We include a clause in the contract with Dell that states if the compression ratio is not met, we will adjust the workload accordingly."

"We only have a single machine and we are currently using half of the hard disk slots. We have asked for an upgrade for the rest of the hard disks but, from my point of view, it costs too much. We have 12 to 15 hard disks inside and if we try to upgrade only the hard disks, it costs the same as the complete system. This is something I don't understand."

More Dell PowerStore 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."
