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

"The solution is scalable."

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

"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."

"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."

"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."

"I appreciate the performance."

"Overall stability is very good. It is a very stable solution."

More Pure FlashArray X NVMe pros

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

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

"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."

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

"It is a very stable product. Stability-wise, I rate the solution a ten out of ten because we did not face any issues in the last three years."

"The features I find most valuable include its use for storage and performance."

More IBM FlashSystem 9100 NVMe pros

"The most valuable feature of Lenovo ThinkSystem DM Series is its capability to tier to the cloud, such as Microsoft Azure or Amazon AWS. Additionally, the integration is good and they are user-friendly."

"One of the most valuable features of Lenovo ThinkSystem DM Series is the snapshot feature."

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

"It has been a perfect fit for the workload that our customer is doing."

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

"The servers are fast and affordable."

"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."

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

More Lenovo ThinkSystem DM Series pros

Cons

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

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

"One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them."

"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."

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

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

"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."

"We would like to see more visibility into garbage collection and CPU performance in the GUI."

More Pure FlashArray X NVMe cons

"IBM FlashSystem 9100 NVMe is an expensive solution, and its pricing could be improved."

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

"I'd like to be able to connect to tape drives behind the storage device to back up the tape if need be. We have all of our storage running in all-flash, and we make a copy on tape. Currently, when we want to hook up tape drives, we have to add some extra equipment, which is a little bit complex. We want IBM to add a feature where we could install a tape into the storage so that we can connect it through a single pane of glass. We'd like to have a feature in the IBM flash storage system so that we can connect backup tape drives through the IBM storage system and we can manage the backup tape from the storage system."

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

"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."

"IBM is currently not offering volume-based encryption or compression, while other brands or IBM's competitors are doing it."

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

"Deduplication and compression should be improved."

More IBM FlashSystem 9100 NVMe cons

"This is an expensive solution."

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

"Many people do not realize that Lenovo has a storage solution, so better marketing from the vendor is needed."

"Lenovo could have a wider variety of storage solutions in the NAS space."

"I would rate the support of Lenovo ThinkSystem DM Series a four out of five."

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

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

"The tool's pricing is high."

Pricing and Cost Advice

"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."

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

"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 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."

"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."

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

More Pure FlashArray X NVMe pricing and cost advice

"The tool's pricing is competitive."

"The price of IBM FlashSystem 9100 NVMe is less than Dell. For upgrades, the Dell solutions are more expensive."

"There are pricing options from the mid-rand to the high-range, of which the suitability depends upon the requirements."

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

"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."

"The product has an average cost."

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

"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."

More IBM FlashSystem 9100 NVMe pricing and cost advice

"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."

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