We performed a comparison between Huawei OceanStor and IBM FlashSystem based on our users’ reviews in four categories. After reading all of the collected data, you can find our conclusion below.
Comparison Results: Based on the parameters we compared, IBM FlashSystem came out ahead of Huawei OceanStor. Although both products have valuable features, our reviewers found that Huawei OceanStor has complex licensing that can make the solution too expensive and needs to improve their tech support’s communication.
"It's just very easy for general block storage."
"We also use VMware integrations developed by Pure, their plugins in our vCenter environment. They help by allowing our non-technical operations teams to deploy new data stores and resize data stores without me having to involve myself all the time to do those simple tasks."
"Technical support has been amazing."
"It's simple, powerful, and ready to use."
"We like the speed. It's very low latency. In virtualization, you can mask lots of problems, and even in code you can mask lots of problems, with low latency. It's just pure speed and low latency."
"Data reduction and compression. Sub millisecond latency."
"It has been very stable. I have not seen or heard of downtime storage issues after moving over to it."
"It simplifies storage."
"The solution works well for non-critical applications that do not require a heavy workload. The tool's all features are valuable."
"The support is excellent."
"Excellent and efficient support, and the product is a good price."
"Huawei OceanStor is a good product. Its interface is very simple. The complexities we encounter with recovery points are gone. We just attach to remote storage, click the application, and it starts."
"If your virtual machine that resides on it completely fills the storage space, thanks to it's built-in function of all-zero data space reclamation, you just have to ask to System Engineer to run a zero-free on hosts (thin provisioned) and you will get more space instantaneously."
"The performance and ease of management are the most valuable features."
"The most valuable feature of Huawei OceanStor is the hybrid applications."
"The solution is scalable."
"The power systems are very reliable if you are running 24/7 operations. For ongoing mission-critical applications, it's the best solution."
"At the FlashSystem level, customers are especially fond of multi-tier and distributed rate systems, particularly the dynamic rate six arrays."
"The most valuable feature of the solution is replication...Stability-wise, I rate the solution a nine out of ten."
"The price-performance ratio is most valuable."
"Over the years, it has become increasingly user-friendly."
"The Flash core models offer amazing performance."
"The performance of IBM FlashSystem is very good. The new technology and high throughput have given us more confidence in the solution. The management of the system has improved and we can control the monitoring system alerts and multiple FlashSystems with the Enterprise Cloud Edition, which is free. The migration of recently stored data to a new flash is much easier. You can move your data because you can utilize it externally."
"The all-flash storage has tier replication capabilities."
"The one major gripe I have is that there is no snapshotting enabled by default on the SAN."
"I would love for them to have a hyper-converged solution."
"I would like to see them lower the costs."
"It was a little costly. The price was ultimately higher than both of the other solutions that we evaluated. I'd say that's the only downside."
"With scalability, I have run into a little problem with our last upgrade. There were some undocumented limitations to the number of drives that our controller could run on. So, instead of putting in a new data pack as we had anticipated, we had to keep adding and removing to get up to the capacity that we needed to be. What should have been a one day process (or a few hours) turned into a month and a half process."
"We've had it in place for about a year and a half and have had zero complaints, other than that box-to-box replication is not encrypted."
"Pure Storage support could be a little better."
"I would like to see support for NVMe, end-to-end."
"The solution could improve by having better integration."
"The security could be a bit more robust."
"The main concern is regarding the usability of the data storage."
"Its storage capacity could be better."
"Its data replication features work slowly for nodes."
"Could have a more stable, lighter Metro and better logging system."
"We did experience a little latency with this solution."
"The duration of the built-in snapshot technology must be improved."
"Our model does not support compression or deduplication."
"Cloud file sharing is an area that needs improvement."
"The deduplication and compression ratio is not very good. It's not reaching a very high ratio."
"The price is very costly."
"There could be some extra features added."
"The generic functionality of IBM FlashSystem, IBM always dismisses using file share or sharing protocols inside their storage hardware, and they only focus on the block-level storage."
"Additional licenses might be added for the fundamental licenses, such as those for copying and flash copies."
"The solution is quite expensive. That's one of the downsides to using it."
