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.

Improves cost efficiency and significantly while boosting workload performance

We have realized several benefits from using Dell PowerStore; we migrated to the current Dell PowerStore models from tiered storage, and now we're using all flash. The dedupe and compression has been a big benefit for us versus the old storage that it was running, and we've seen the performance of all flash for our storage services. My company finds particular features within Dell PowerStore valuable, primarily the cost benefits for the performance that we get out of the platform. We've definitely seen the benefit on that side of it, including the cost per terabyte, and the support from Dell has been excellent as well. We haven't had any issues with it, so it's been very reliable as a platform for us. The performance metrics I use to measure success with Dell PowerStore are all IOPS and throughput. We are not using it with AI workloads on Dell PowerStore, so it's primarily just customers running IaaS, however, it is important that it's reliable and performs well, and we get that from Dell PowerStore. Dell PowerStore has supported growth and operational success for my business; a key driver at the moment is consolidation, and the dedupe and compression ratios allow us to standardize on a single platform. This has helped improve our operational metrics and overall operations, as we now have only one vendor to support and one set of storage arrays to manage. We have a very clear path into support and escalation if there is an issue, and we are not dealing with multiple vendors.

"Other vendors have included a block and file system. IBM doesn't include a file system. And yet, it's very necessary for all organizations' networks to have file systems. We have other systems for the file system, however, ideally, we would like to have one system with these features."

"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."

"There could be a possibility of not requiring to buy a new box while upgrading to a newer version."

"The pricing should be more competitive."

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

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

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

"The licensing is on a yearly basis."

More Pure FlashArray X NVMe pricing and cost advice

"When we compared it with the other solutions, the pricing of PowerStore was equal. The pricing is good."

"Dell PowerStore is more expensive than Dell EMC Unity All Flash. Dell PowerStore's performance metrics were way higher than what Dell EMC Unity All Flash offered."

"It is expensive compared to one of its competitors."

"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."

"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."

"The software features are included in the pricing without any additional purchase requirements."

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

More Dell PowerStore pricing and cost advice

"Compared to its competitors, IBM's offering is the most cost-effective."

"The tool's pricing is competitive."

"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."

"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."

"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 solution's price is competitive."

"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."
