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 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."

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

"I appreciate the performance."

"We generally always advise people to make the choice to go with Pure Storage because they won't regret it."

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

"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."

"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."

More Everpure FlashArray X NVMe pros

"It's a great product. Integrating PowerStore with the IT workflow is easy."

"The rack space I'm saving alone is an ROI because I'm able to then use those racks for more servers."

"The solution's technical support is excellent. I rate the technical support a ten out of ten."

"It is a stable solution."

"For the targeted workload that we have, it's performing substantially better than we had expected within our business case."

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

"It's really good, price-wise. It's cost-effective."

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

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

"In terms of what needs improvement, the dashboard and management could be simplified."

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

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

"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."

"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."

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

"One area that I haven't been sold on yet is the POD replication."

"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."

More Everpure FlashArray X NVMe cons

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

"The solution’s security and technical support could be improved."

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

"During the installation phase, the licensing part was not straightforward. It was very difficult for the technicians, who are not trained Dell EMC technicians, to do the licensing because the information on their website is not straightforward."

"Earlier the quality of support was excellent, but now it has deteriorated. We do not get quick support, and we have to wait longer to get the support."

"After upgrades, there were a few bugs in the product, and it can be considered as an area of concern where improvements are required."

"It was very new when we first deployed it a year ago. Even the upgrade processes and knowing what to expect, as well as documentation, could be more robust."

"We used to be able to see the metrics for our customers. On Compellent, we could look up that customer and see all the metrics. That is not allowed for us now. We cannot do that anymore. I have to be explicitly allowed by the customer to do that, and some companies' security does not allow that."

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."

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

Pricing and Cost Advice

"The product is expensive."

"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 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."

"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."

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

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

"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."

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

More Everpure FlashArray X NVMe pricing and cost advice

"Dell PowerStore has been priced aggressively, especially when compared to other NVMe storage options. It is likely one of the most cost-effective options for organizations seeking a pure NVMe play in terms of pricing."

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

"As compared to others, PowerStore is cheaper."

"We are happy with the pricing that we get from Dell."

"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."

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

"Licensing is very simple. Everything is included in the basic license. There are no concerns about having to pay to add a feature. Everything is there."

"There are no separate licenses required as all the basic licenses are included in the bundle."

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."
