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.

"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."

"The most valuable features of this solution are its ease of use and performance."

More Pure FlashArray X NVMe pros

"The solution's most valuable features are its form factor and switching to NVMe."

"I am saving costs because I am getting better performance and deduplication rates."

"For access from virtual machines, iSCSI, and NFS, it is very good. It helps increase performance."

"Dell PowerStore has benefited our organization through cost savings."

"To growth and business success, Dell PowerStore contributes definitely because the appliances have these expansion enclosures and scale-up and scale-out work pretty well with Dell PowerStore, up to a certain degree."

"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 most valuable feature is the functionality of the integration between the storage and the domain."

"The stability has been excellent."

More Dell PowerStore pros

"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."

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

"The most valuable feature of IBM FlashSystem 9100 NVMe is the snapshot. We use it daily for all of the storage units."

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

"The most valuable feature is the speed."

"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

"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."

"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."

"I'd like to see the product implement active replication for vehicles such as VMware."

"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."

"We need better data deduplication."

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

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

"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 Pure FlashArray X NVMe cons

"The storage could be improved. I would like a feature for how to best secure an appliance and the storage since we are connecting the container to the public cloud. I would like them to develop another level of security, making it more secure than from what they have now."

"You cannot delegate permissions."

"The previous version of Dell PowerStore we used was easier to use compared to the current one. They have made it more cumbersome to handle, although it still works. It has become more complicated to manage."

"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."

"The initial setup was a little bit cumbersome."

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

"When you create a case on Dell's support website, you don't always get someone who is experienced in the kind of systems you need help with...making it an area where Dell's support team needs to make improvements."

"If I could improve Dell PowerStore, I would suggest that integrations into backup platforms be a little more streamlined."

More Dell PowerStore cons

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

"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 support could be better."

"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."

"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."

Pricing and Cost Advice

"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."

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

"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."

"Pure FlashArray X NVMe’s pricing is cheaper than other products."

"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."

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

More Pure FlashArray X NVMe pricing and cost advice

"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."

"The solution is expensive."

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

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

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

"With compression, we were able to have a solution within our company's budget. We include a clause in the contract with Dell that states if the compression ratio is not met, we will adjust the workload accordingly."

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

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

More Dell PowerStore pricing and cost advice

"The product has an average cost."

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

"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."

"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."

"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 tool's pricing is competitive."

"The solution is priced well."

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