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

"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."

"The solution is very straightforward to set up."

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

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

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

"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."

More Pure FlashArray X NVMe pros

"Dell PowerStore has positively impacted our organization by improving the user experience, as we were having issues with the hybrid storage we had in the past, so we decided to go to an all-flash solution, and it made it possible to give a better experience because we were having heavy delays on the applications."

"The solution is resilient and reliable, the support is very good, it performs fast with excellent IOPS, and their deduplication and compression ratio features are excellent."

"Dell PowerStore has good value for money and some scalability features that are better than other products."

"The most valuable features of Dell PowerStore are the resilience, scalability, flexibility of expansion, and ease of managing the entire solution including the servers and storage."

"The beauty is the simplicity - customers can manage multiple workloads from a single dashboard with scale-out architecture."

"The solution is stable."

"The best feature of Dell PowerStore is its flexibility for expanding data storage."

"The most valuable feature of Dell PowerStore is the ease of deployment and general use."

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

"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."

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

"Maybe the price can be reduced since the solution is very expensive."

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

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

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

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

"We would like to see more visibility into garbage collection and CPU performance in the GUI."

More Pure FlashArray X NVMe cons

"While using Dell PowerStore's interface in our organization, we sometimes miss out on some information."

"One improvement I would suggest relates to the service that pings Dell when there's an issue. I would say it needs to be more transparent."

"Dell PowerStore currently only allows us to copy data from our main production system to the disaster recovery site."

"Dell PowerStore is an unfinished product compared to the HPE systems because it is relatively new."

"There are certain shortcomings with the technical support team of Dell PowerStore, where improvements are required."

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

"I would improve Dell PowerStore by enhancing the replication feature because currently, users are limited to one applier, from one cluster, a Dell PowerStore cluster, to another Dell PowerStore cluster, but are not able to configure a three-site scenario."

"As a partner, I'd like to be added to each customer's CloudIQ to take a look."

More Dell PowerStore 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

"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."

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

"Pretty much everything that you need is licensed when you buy the product. Licensing to me is different than the maintenance cost, but they can bleed into one another. We buy the product, and we expect three years of support bundled into what we negotiate on our storage arrays. I would start to see maintenance costs going into the fourth year, but we're not there yet."

"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."

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

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

More Pure FlashArray X NVMe pricing and cost advice

"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."

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

"If we use the 500 or 1000, the licensing and pricing are reasonable. PowerStore can compete with any vendor and the price isn't that expensive."

"The pricing structure and licensing model of Dell PowerStore are pretty decent. It's pretty competitive."

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

"The price of Dell EMC PowerStore could be better, it is a bit expensive."

"We are currently using Dell PowerStore for our smaller storage and there is no competition for pricing."

"The pricing rates at seven out of ten as it is considered overpriced. Entry-level models are reasonably priced, starting around $30,000 for a base model with 6 drives. However, upgrades become costly - adding 6 additional drives can cost another $30,000."

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."
