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.

Enhanced storage performance and an easy setup with compression challenges
We use IBM FlashSystem 9100 NVMe as a storage device in the IT industry The features I find most valuable include its use for storage and performance. The solution's compression needs to be improved, as it's not the best. Furthermore, support from the partner could also be improved as it's been…

Efficient data management leads to significant cost savings through advanced inline deduplication
NetApp's inline deduplication and compression are unmatched compared to other vendors. With both deduplication and compression inline, we experience no cost in terms of performance on the systems, however, we have huge savings on the storage side. We can turn it on for everyone and save storage space, allowing us to sell more to customers. NetApp also provides us with an interface for VLAN separation that no other vendor can provide, allowing our customers distinct, separated network layers in between.

Quotes from Members

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

Pros

"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"Everything, especially the VMs inside, is pretty fast."
"It has benefited my organization because it has reduced time to insights."
"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."
"Overall stability is very good. It is a very stable solution."
"The high availability of the product is the most valuable 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."
"The most valuable feature of the solution is its upgrades, as we don't have to do much homework because of its different controllers."
"The features I find most valuable include its use for storage and performance."
"The solution is more available for IOPS warehousing, resolving issues, and reporting than other products."
"The most valuable feature is the speed."
"The most valuable feature of IBM FlashSystem 9100 NVMe is the snapshot. We use it daily for all of the storage units."
"IBM FlashSystem 9100 NVMe is easy to use and comes with good performance."
"The high performance and high availability improved our overall processes."
"NetApp's hot and cold storage are its most valuable features. We currently use the A series. Immutable snapshots are another advanced security feature that is positive."
"NetApp's inline deduplication and compression are unmatched compared to other vendors."
"We've reduced downtime. Without all of NetApp's benefits, we would have had to reconfigure parts of storage that would have required downtime. We have dramatically reduced our downtime through successive generations of NetApp, allowing us to get Five 9s availability."
"MetroCluster is the best product on the market. It synchronizes the storage. NetApp's update packages are a huge advantage because the firmware and server updates are in one package."
"NetApp support is fantastic."
"The amazing thing is that whenever we have come up with an issue where we need to get something done, and it wasn't necessarily available, they could do things for us, usually within the next revision of the software."
"NetApp helps us get the fastest output."
"NetApp AFF A-Series is faster and more robust compared to the all-flash storage of NetApp."
 

Cons

"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"Adding some functions to the product would be beneficial."
"There is room for improvement in the pricing of the product."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"I would like to see replication and DR features in the next release of this solution."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"The support could be better."
"The solution's compression feature could be better."
"The solution's compression needs to be improved, as it's not the best."
"IBM FlashSystem 9100 NVMe is an expensive solution, and its pricing could be improved."
"The pricing should be more competitive."
"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."
"I would like to have replication functionality built directly in the product, rather than having to use a separate device for this."
"In the FlashSystem 5200, there were only four ports of 32 fiber channels for the architecture. This has been resolved in the new generation."
"Pricing could always be lower."
"NetApp AFF A-Series should work on cost. The solutions, especially enterprise-level storage, should be more affordable to improve their appeal to businesses."
"I really don't have a lot of complaints. In the past, there were issues, however, they've really done a great job of reaching out."
"We have several problems with the limitations of NetApp systems in terms of volume shares. We have a brick in a 700 or a controller, and we sometimes make small volumes, but Kubernetes container volumes don't allow us."
"It would be helpful if our partner organized a yearly session with my team to discuss the new feature sets on our current solutions and other ways NetApp can help us. Perhaps we are missing some information to help us make the right decision."
"The solution's ransomware protection could be improved."
"NetApp is shifting to the cloud and adopting AI, but it is not improving its core technology to deliver faster storage. We're still waiting to see if it improves speed with solutions like the 90 series."
 

Pricing and Cost Advice

"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'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."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"As far as the licensing costs, everything is included in the license."
"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."
"The product is expensive."
"The licensing is on a yearly basis."
"The support cost per array is about $20,000 a year for 24/7 support."
"The tool's pricing is competitive."
"The solution is priced well."
"The price of IBM FlashSystem 9100 NVMe is less than Dell. For upgrades, the Dell solutions are more expensive."
"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."
"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 product has an average cost."
"Compared to its competitors, IBM's offering is the most cost-effective."
"The solution's price is competitive."
