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.

Quotes from Members

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

Pros

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

"The latency is good."

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

"The database workloads are pretty fast because I frequently move data from here to there."

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

"On a scale of one to ten, I rate Pure FlashArray as ten."

"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."

"Technical support has been helpful and responsive."

More Pure FlashArray X NVMe pros

"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 solution is more available for IOPS warehousing, resolving issues, and reporting than other products."

"Its ease of use, performance, and hardware compression is very useful feature."

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

"The most valuable features of IBM FlashSystem 9100 NVMe are its steady performance and usefulness in high-traffic environments."

"The most valuable feature of the solution is its upgrades, as we don't have to do much homework because of its different controllers."

"Good performance with a user-friendly UI."

"The most valuable feature is the speed."

More IBM FlashSystem 9100 NVMe pros

"Lenovo ThinkSystem DE Series is highly reliable, especially for block-level storage. It is stable, with minimal downtime and no issues beyond user errors."

"The solution is very easy to troubleshoot. It's one of the most valuable features. It also doesn't take long to deploy and normally it comes with a three-year warranty."

"The solution is very easy to set up."

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

"Its initial setup process is easy."

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

More Lenovo ThinkSystem DE Series pros

Cons

"The UI for this solution needs to be improved."

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

"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. Storage replication should be essential, and the analytics should not incur extra charges."

"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."

"Maybe the price can be reduced since the solution is very expensive."

"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."

"The software layer has to improve."

More Pure FlashArray X NVMe cons

"IBM's support is not good. I experienced a big problem where I opened the console IBM Storage and would see that something was broken. I called the call centers, and I said, "I have a problem. My drive is not working." They want me to give them the serial number, I gave it to them and they told me "I cannot find your product. Your product is not here.""

"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."

"I would like to have replication functionality built directly in the product, rather than having to use a separate device for this."

"The storage system itself should have built-in capabilities for different ransomware attacks."

"Deduplication and compression should be improved."

"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."

More IBM FlashSystem 9100 NVMe cons

"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration. I don't know if there is room for a more hyper-conversion structure to work with, but this would be easier."

"Usually, when a part fails, we have to replace it and it takes a while. It would be better if the part could be available locally here in Kenya so we don't have to wait so long to repair the solution."

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

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

"The product could support advanced software integrations."

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

"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."

More Lenovo ThinkSystem DE Series cons

Pricing and Cost Advice

"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."

"Our licensing fees are $500,000+ USD."

"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."

"The licensing is on a yearly basis."

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

"The product is expensive."

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