We performed a comparison between IBM FlashSystem and Lenovo ThinkSystem DE Series based on real PeerSpot user reviews.
Find out in this report how the two All-Flash Storage solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI.
"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."
"The solution is very straightforward to set up."
"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"It has benefited my organization because it has reduced time to insights."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"It has good, reliable, fast storage."
"The most valuable feature is that is supports a high IOPS rate."
"We are a 100% satisfied with the stability of the solution."
"The initial setup was really straightforward. It was not complex. Deployment took one month, due to the data migration duration."
"Installing FlashSystem is very easy. It takes less than half an hour, and I can handle it all myself."
"Flash disk with Easy Tier option"
"The storage system is one of the best in the world."
"IBM FlashSystem is a powerful effective storage solution. Additionally, it is user-friendly, anyone can use it."
"It is simple to make an update."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"The most valuable features of the Lenovo ThinkSystem DE Series are the dual controllers, available installation documentation, and the option of multiple host bus adapter interfaces."
"Lenovo ThinkSystem DE Series is simple to use"
"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."
"The solution is very easy to set up."
"Its initial setup process is easy."
"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions. It's also easy to use."
"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."
"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."
"They could add more support for file storage and different types of storage."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"The tool's pricing is higher than competitors."
"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"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."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"Our model does not support compression or deduplication."
"The solution is not easy to use and could improve."
"The marketing could be improved."
"Events/log analysis tools."
"Replication features need improvement. Currently, they are there in the product, but I'm not sure as to how it works exactly."
"The storage capacity of this solution could be improved."
"Our customers have raised concerns about the limitations of the FlashSystem 5200 and 7300, which only offer a 32-gigabyte connection."
"I would like to see bigger modules."
"There could be a snapshot feature in the solution."
"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."
"The features are limited."
"In the next release, I would like to see more functionality. But, again, it is an entry-level product."
"Improvements can be made to the product's performance."
"Its performance could be faster."
"The solution could be more scalable, although it suits our present needs."
"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."
