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

"One of the best features is the support, which is excellent."

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

"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."

"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 cost for Pure may be high, but the reliability and scalability make it well worth the money."

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

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

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

More Everpure FlashArray X NVMe pros

"PowerStore helps to simplify IT operations."

"We have found the solution very stable and we like it very much."

"Dell PowerStore is very easy to deploy."

"In my view, if a storage array requires constant monitoring or 'whispers in your ear' every five minutes with issues, it isn't doing its job. Because the sites currently running PowerStore are silent and stable, I consider the Return on Investment to be excellent. It provides exactly the peace of mind we are looking for."

"The most valuable feature of Dell PowerStore is its easy-to-use feature, specifically the simplicity."

"I assess customer service and technical support as very good."

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

"The most valuable feature of Dell PowerStore is Metro Volumes."

More Dell PowerStore pros

"It is a very stable solution."

"It is a very stable product. Stability-wise, I rate the solution a ten out of ten because we did not face any issues in the last three years."

"It is a high-performance product that serves our requests well."

"The most valuable feature is the speed."

"IBM FlashSystem is an excellent product."

"It's easy to use, has good stability, and many features."

"The FlashCore modules support more value to the architecture due to their unique characteristics."

"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."

More IBM FlashSystem 9100 NVMe pros

Cons

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

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

"We need better data deduplication."

"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."

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

"The software layer has to improve."

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

More Everpure FlashArray X NVMe cons

"We are looking for the Dell PowerStore to become more mature to maximize our use cases."

"Many customers are looking for a cyber recovery feature included in PowerStore. We would like to see this added in a future release."

"Technical support rates at a seven out of ten, primarily due to response time rather than knowledge."

"Dell PowerStore customer service is good, but sometimes they usually take a lot of time to understand the issue."

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

"The performance of PowerStore is good, but I don't feel the software is completely ready; the system is fast but not stable enough and I would not buy the system again."

"I am not satisfied with Dell PowerStore because of stability. Stability and complexity of some features and configurations are issues with Dell PowerStore."

"When it comes to Dell PowerStore, I would like to see more integration and more security features included. It's unfortunate that the solution does not feature Flash trace."

More Dell PowerStore cons

"Other vendors have included a block and file system. IBM doesn't include a file system."

"The support could be better."

"IBM FlashSystem 9100 NVMe is an expensive solution, and its pricing could be improved."

"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."

"The pricing should be more competitive."

"The solution's compression needs to be improved, as it's not the best."

Pricing and Cost Advice

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

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

"The licensing is on a yearly basis."

"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."

"As far as the licensing costs, everything is included in the license."

More Everpure FlashArray X NVMe pricing and cost advice

"As compared to others, PowerStore is cheaper."

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

"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."

"Dell PowerStore charges for the hardware warranty every three years. The price will depend on the storage model or how much hardware it has."

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

"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."

"The solution is expensive."

More Dell PowerStore pricing and cost advice

"The solution's price is competitive."

"The product has an average cost."

"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 price of the FlashSystem 9100 NVMe is reasonable."

"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."

"The solution is priced well."
