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 latency is good."

"We are satisfied with the performance as it is significantly faster compared to traditional storage options."

"On a scale of one to ten, I rate Pure FlashArray as ten."

"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."

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

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

"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."

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

More Pure FlashArray X NVMe pros

"Dell PowerStore's compression and deduplication technologies are a big help for our organization. It's saving us a lot of storage compared to what we were previously using."

"It is very easy to use. Access is very friendly. It shows you a lot of important information at the first glance. It has been very easy to use."

"The most valuable feature of Dell PowerStore is the all-NVMe flash storage. This is the most powerful feature of this series. It supports compression and duplication leads."

"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."

"We started working with the first generation Dell PowerStore in 2020, and our customers are already migrating to the second generation."

"The solution is stable."

"In the five months we've been running Dell PowerStore, it's been 100% uptime with no issues at all, so it's been excellent."

"If I were giving advice to another company looking at Dell PowerStore, I would say that you cannot go wrong with Dell, as the sales and support teams are always top notch."

More Dell PowerStore pros

"IBM FlashSystem 9100 NVMe is one of the leading storage systems in the world...I rate the solution's stability a ten out of ten."

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

"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."

"A key feature is that compared to storage systems that we've been familiar with over decades, IBM simply does not fail. The reason is that IBM is the only manufacturer that engineers its own flash module, and there is a key architectural difference from everything else that we have seen in the market. The difference is that the flash module has the computational capability, which allows reliability and capacity enhancements to be uploaded from the main controllers and run in each module. So, each of the flash drives becomes its own little storage system, and that is extremely effective architecture. In this field, with this type of system, IBM has made a statement. They've never had one of these modules cause an outage. So, the failure rates on these things are just in a whole different universe from what we were accustomed to."

"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."

"Good performance with a user-friendly UI."

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

Cons

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

"The software layer has to improve."

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

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

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

"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."

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

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

More Pure FlashArray X NVMe cons

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

"The pricing point must have better positioning."

"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."

"Scalability can be improved as it meets our requirements currently, but in the longer run, scalability might be a concern."

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

"Could be improved by including a synchronizing feature for the file systems."

"The pricing could be lower. It is very expensive."

"The initial setup was a little bit cumbersome. We had a bit of an adoption process internally. It wasn't immediately straightforward on day one."

More Dell PowerStore cons

"I would like to see IBM products become more affordable because they can be quite expensive, which limits their accessibility to a broader customer base."

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

"IBM FlashSystem 9100 NVMe is currently at the end of its lifespan and will soon become obsolete in the markets."

"There is a tool provided by IBM for repairing batteries which can only be utilized by those who have an IBM technical advisor under service contract. However, for individuals who do not have such a contract, the tool can be difficult to use and requires a zip file copy. I believe that it would be greatly beneficial if the tool were made more user-friendly and accessible for all individuals who need to repair batteries."

"In the FlashSystem 5200, there were only four ports of 32 fiber channels for the architecture. This has been resolved in the new generation."

"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."

"The ZIO interface could be improved."

More IBM FlashSystem 9100 NVMe cons

Pricing and Cost Advice

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

"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 licensing is on a yearly basis."

"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."

"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."

"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."

"The product is expensive."

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

More Pure FlashArray X NVMe pricing and cost advice

"PowerStore's pricing is reasonable."

"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."

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

"Dealing with the licensing part of the product is very simple, especially considering the fact that we don't have many licenses associated with the tool."

"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."

"The pricing is good. There's no need to pay for a license; it's all-inclusive."

"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."

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

More Dell PowerStore pricing and cost advice

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

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

"The price of IBM FlashSystem 9100 NVMele can be considered affordable when taking into account the operating system that is required for it to function properly. This operating system, which is licensed by IBM, may carry a higher cost, but it is worth the investment for larger corporate entities, such as insurance companies, Fortune Five companies, and banks, who make up a significant portion of their target market. The FlashSystems are designed for larger corporations and multinational enterprises, and may not be the most cost-effective solution for smaller businesses."

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

"It's a lot less costly than cloud storage. People get surprised by the cost of cloud storage, which is extremely expensive and four or five times the cost of storage on-premises. People don't realize what they're spending on storage until they start getting bills from Amazon, Microsoft, and others. This is a good way to reduce your cloud storage expenses."

"The solution's price is competitive."

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

"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."
