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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."

"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."

"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."

"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."

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

"It has good, reliable, fast storage."

"Everything, especially the VMs inside, is pretty fast."

"The solution is scalable."

More Pure FlashArray X NVMe pros

"The improvement is massive; even a couple of milliseconds makes a significant difference to our production throughput, allowing products to leave the door more efficiently, which also cuts back on overtime and ensures we can complete our daily tasks in the required hours."

"The most important aspect of Dell PowerStore in comparison to any other platform is that it helps us save costs while giving more value per GB per dollar spent. It provides an industry-leading DRR ratio."

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

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

"Benefits of Dell PowerStore compared to Unity 400 and 650F, which we were previously using, are significant: we benefit from extensive deduplication for non-database applications, which saves us a considerable amount of costs, and the performance has improved dramatically due to advancements in technology, such as TLC disks and NVMe technologies."

"The features of Dell PowerStore I like the most include the simplicity, unified storage, and high availability."

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

"Dell PowerStore's valuable feature stems from an area named Metro Volume, which is quite simple to implement. The feature works fast and is good."

More Dell PowerStore pros

"There are many valuable features of IBM FlashSystem 9100 NVMele I have found to meet my needs. Specifically, the maintenance cycle is a standout feature of this solution. The main component of the IBM FlashSystem 9100 NVMe is the maintenance of the batteries, which have a predetermined and reliable four-year life cycle. This is in stark contrast to other solutions that may use spinning disks, which can fail unexpectedly, causing unwanted downtime and maintenance. Having a predictable maintenance cycle is a significant advantage and has made this solution a preferred choice for me."

"The solution is more available for IOPS warehousing, resolving issues, and reporting than other products."

"The storage serves the virtual environment. Most of our applications run in the virtual environment, and it serves nearly 30% of the bank's capacity."

"The high performance and high availability improved our overall processes."

"Its ease of use, performance, and hardware compression is very useful feature."

"What I like about the product are its high availability, maximum efficiency in performance, and its ability to handle a high level of I/O operations."

"Good performance with a user-friendly UI."

"The most valuable features of IBM FlashSystem 9100 NVMe are its steady performance and usefulness in high-traffic environments."

More IBM FlashSystem 9100 NVMe pros

Cons

"The UI for this solution needs to be improved."

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

"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."

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

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

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

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

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

More Pure FlashArray X NVMe cons

"The setup process could be improved. We had some issues regarding configuration and the time it took to do things. It wasn't specifically the people we worked with, but more the process and how it's done. They can work on that."

"I would say a bit more user-friendliness and in-depth features in the monitoring interface of CloudIQ would be an improvement; sometimes it is quite difficult to find the information I want."

"I would suggest that Dell PowerStore could come with various other features, such as a hybrid model apart from only all-flash, which would really help the customers."

"If I needed more capacity, it quickly moves out of Dell PowerStore into something else. If I needed something more, I would prefer to stay in the Dell PowerStore ecosystem."

"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."

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

"I do not have any current pain points that I would like them to fix, although we did have one issue when an update stopped the phone-home solution, however they fixed that via support."

"Reporting is an area that could be improved. It's very simplistic sometimes, and some of the very technical guys on my team want to see more of the details and be able to massage the report a little bit better."

More Dell PowerStore cons

"The tool's architecture is complex. It also needs to add data utilization reports."

"The pricing should be more competitive."

"The ZIO interface could be improved."

"The storage system itself should have built-in capabilities for different ransomware attacks."

"The efficacy of the GUI in IBM FlashSystem 9100 NVMe could be enhanced, and it would be beneficial to include a feature that can prevent ransomware attacks."

"Deduplication and compression should be improved."

"The solution's compression feature could be better."

"In the future, the limitation is upgrading the same storage by adding a shelf to the desk. There is a limitation in the backend connection between the storage and extended shelf."

More IBM FlashSystem 9100 NVMe cons

Pricing and Cost Advice

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

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

"The product is expensive."

"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."

"We pay approximately $50,000 USD per year in licensing fees."

"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

"In the pricing and licensing department, the product is always too expensive."

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

"As compared to others, PowerStore is cheaper."

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

"There's still a cap on the upgrade path, where you can consume all the engines within the frame before you have to go to another frame... Normally, we exceed the IOPS on the frames before we can ever exhaust the storage, so anything they can do to help us avoid stranded storage capacity, capacity that we couldn't get to, would be beneficial."

"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."

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

More Dell PowerStore pricing and cost advice

"On a scale of one to ten, where one is a low price and ten is a high price, I rate the pricing an eight."

"The solution is priced well."

"The price of IBM FlashSystem 9100 NVMe is less than Dell. For upgrades, the Dell solutions are more expensive."

"Compared to other solutions, the cost of IBM FlashSystem 9100 NVMe is reasonable, with a one-time payment of around $70,000. However, additional support is available for $25,000 for three years. The overall maintenance cost is steep."

"There are pricing options from the mid-rand to the high-range, of which the suitability depends upon the requirements."

"The price of the FlashSystem 9100 NVMe is reasonable."

"Price-wise, the solution offers excellent pricing to its users. In short, the prices offered by the solution are competitive compared to similar solutions."
