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.

Performance and cost-effectiveness are maximized with seamless setup and significant ROI

I use Lenovo ThinkSystem DE Series to replace the old storage in our infrastructure. Additionally, I use it in customer infrastructures to migrate from the old storage to the new one On the M storage, I find the best features to be deduplication and compression. On the DE storage, the most…

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

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

"I appreciate the performance."

"The solution uses newer technology for deduplication and compression."

"Technical support has been helpful and responsive."

"The initial setup was extremely simple and straightforward."

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

"Everything, especially the VMs inside, is pretty fast."

"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."

More Pure FlashArray X NVMe pros

"This solution is good for virtualization and meets the need for CPU and RAM requirements."

"The solution's initial setup process is easy."

"Its initial setup process is easy."

"The solution is very easy to set up."

"We have been working with the solution for around a year and so far it has shown itself to be stable."

"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."

"Lenovo ThinkSystem DE Series is quite an elementary box, no frills. It does not have all the functionality of the DM but it is acceptable, it does its task. It integrates pretty well."

"I would rate the stability of Lenovo ThinkSystem DE Series as a ten."

More Lenovo ThinkSystem DE Series pros

"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."

"NetApp helps us get the fastest output."

"The deduplication and compression options from NetApp AFF A-Series are good to use for efficient storage capacity."

"NetApp's inline deduplication and compression are unmatched compared to other vendors."

"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'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 AFF A-Series is faster and more robust compared to the all-flash storage of NetApp."

"NetApp support is fantastic."

More NetApp AFF A-Series pros

Cons

"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."

"Adding some functions to the product would be beneficial."

"It feels more suitable for small and medium-sized businesses rather than enterprises."

"The tool's pricing is higher than competitors."

"We would like to see VNC integration or be able to use Pure Storage with VNC."

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

"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."

"We need better data deduplication."

More Pure FlashArray X NVMe cons

"Improvements can be made to the product's performance."

"In the next release, I would like to see more functionality. But, again, it is an entry-level product."

"There could be a snapshot feature in the solution."

"The solution could be more scalable, although it suits our present needs."

"The product could support advanced software integrations."

"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."

"The type of connection that is used in Lenovo ThinkSystem DE Series should be improved."

"Its performance could be faster."

More Lenovo ThinkSystem DE Series cons

"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."

"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."

"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."

"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."

"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."

Pricing and Cost Advice

"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 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."

"The product is expensive."

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

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

"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."

More Pure FlashArray X NVMe pricing and cost advice

"The best thing about this solution is its price, which reduces our costs."

"The solution's price could be better."

"It is an expensive solution."

"The price of the Lenovo ThinkSystem DE Series is a one-time purchase. There is a global price list available to find the price of the solution."

"We have a five-year contract for providing support."

"For an all-flash setup, the cost is around $20,000 for a decent configuration."

"The pricing is fair and low compared to other products in this category."

"The pricing for this solution is good compared to HP or Dell EMC."
