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.

With an easy initial setup phase, the tool is useful for multi-site replication and DR

The configuration part of the product is an area with certain shortcomings where improvements are required. If the product is up and running after, if it goes down, my company has observed that there are multiple failures that occur in the tool, so it needs to be reinstalled from scratch. The tool should have an automated feature or an automated option to handle the aforementioned scenario, which one can simply go and reset, after which the tool should be reinstalled with the same configuration.

Quotes from Members

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

Pros

"I appreciate the performance."

"The latency is good."

"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."

"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."

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

"It has benefited my organization because it has reduced time to insights."

"The tool's valuable features are speed, security, data compression, and reliability. Its data compression feature is the best that we have ever seen. It helps us to save money and resources."

"The most valuable feature of this solution is reliability."

More Pure FlashArray X NVMe pros

"The ransomware protection feature is housed in a separate unit, specifically addressing the top twenty most critical threats."

"It works very well."

"The most valuable features of VMAX are its performance and GUI interface."

"The snapshot feature has been precious for our testing processes, application development, and managing testing environments due to its efficiency and ease of use."

"We haven't experienced any outages or core-level issues in the last ten years, making us comfortable with the storage solution."

"The product's initial setup phase was good."

"Scalable and stable storage array."

"Ability to cluster two storages together with HA availability."

"The most valuable feature of the Lenovo ThinkSystem DM Series is its ability to store data well."

"The value we derive from using it is greater than other alternatives like HPE and Dell."

"The servers are fast and affordable."

"The FlexClone feature is the solution's most valuable aspect."

"The solution offers very good reliable systems and storage for our clients."

"Last year, I did a DM Series installation with my colleague, and this installation was effortless because we had Lenovo support on the phone, so it was easy to get help if we had any problems."

More Lenovo ThinkSystem DM Series pros

Cons

"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."

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

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

"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."

"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."

"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."

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

More Pure FlashArray X NVMe cons

"The configuration part of the product is an area with certain shortcomings where improvements are required."

"The scalability of VMAX is somewhat limited, especially in terms of cache scalability. We've had to procure additional engines to address this limitation."

"The scalability of VMAX is somewhat limited, especially in terms of cache scalability."

"Improvements are needed in both partition recovery and scalability."

"There is room for improvement in the centralized administration."

"We encountered some challenges during large data migrations that could be addressed for smoother transitions."

"Lenovo ThinkSystem DM Series is not stable. If I have sold fifty boxes, about fifty percent of them experienced failure."

"Lenovo ThinkSystem DM Series could improve by having a snapshot feature. Additionally, there can be other features added to help restore the data faster."

"The Lenovo ThinkSystem DM Series was very hard to configure. Installation of the product was very hard. These are its areas for improvement."

"The licensing model needs to be revisited. It needs to be simplified."

"The solution should change the licensing model and allow customers to choose features based on their requirements."

"There might be improvements needed in drive throughput as disk speed has been a limitation on Windows servers."

"This is an expensive solution."

"The solution needs a simpler licensing theme around the DM series. The problem is if you only need one of the features, you still have to buy the whole thing. The licensing needs to be more granular or flexible so you have the option to only license FlexCone or Inline Compression features."

More Lenovo ThinkSystem DM Series cons

Pricing and Cost Advice

"The product is expensive."

"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."

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

"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."

"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."

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

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

More Pure FlashArray X NVMe pricing and cost advice

"The price falls within the mid-range, neither inexpensive nor high-priced."

"It is not a cheap product."

"The solution's pricing is similar to Dell and HPE."

"The price of the Lenovo ThinkSystem DM Series is good."

"The solution is highly-priced."

"Lenovo offers two software tiers for the DM Series: basic and premium. If you need more features like the MetroCluster, you must buy the premium version. You can stick to the basic software if you don't need MetroCluster or features like asynchronous replication. That makes DM Series a little cheaper."
