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.
"The scalability is good."
"It's just very easy for general block storage."
"I find two features of Pure Storage most valuable. The first is the "safe mode" function, and the second is its simplicity."
"The ease of management is one of the most valuable features of this solution. I would have also said that it's pretty fast but now our SQL servers are starting to beat it up pretty bad."
"It helps us maintain uptime much better than other solutions we've used in the past, and the support is extremely quick and responsive."
"The most valuable feature is its data reduction."
"The reliability is very good."
"The speed of the Pure FlashArray is very, very fast and nothing in the market can compare to it."
"Huawei OceanStor is easy to manage."
"OceanStor is cheaper than Dell EMC, and its management interface is quite simple."
"Huawei OceanStor is designed with built-in high availability features, such as fault tolerance, ensuring consistent data access and minimizing downtime."
"The support is excellent."
"The initial setup was straightforward."
"It is a highly available product."
"Generally stable with good technical support."
"Its technical support team is helpful."
"At the FlashSystem level, customers are especially fond of multi-tier and distributed rate systems, particularly the dynamic rate six arrays."
"The performance of the All-Flash System is very good. There is more enhanced performance and data production in the solution, which I appreciate."
"We are a 100% satisfied with the stability of the solution."
"The most valuable feature in demand is virtualization and its support storage of virtualization features."
"The most valuable feature of the solution is SCM (Storage Class Memory), which has the lowest latency value in the storage industry."
"The initial setup was really straightforward. It was not complex. Deployment took one month, due to the data migration duration."
"The all-flash storage has tier replication capabilities."
"IBM FlashSystem is a stable solution."
"I think replication is one area that still needs improvement. Earlier, Pure Storage FlashArray only had IP-based replication. There was no API-based replication, but they have enhanced the feature now. However, they need to work on API replication for C-type of arrays."
"I would love for them to have a hyper-converged solution."
"CIFS and SMB Shares cannot be mounted directly."
"There are many features which need to be added, particularly on the replication side."
"I would like to see more detailed reporting on the data. However, it would be nice to know what are the exact VMs usage after deduplication and/or what that VMs actual latency and bandwidth is, outside of VMware."
"What it needs to do is work a little closer with solutions, like VMware, so it understands the particular workloads that are on it. Today, it does not understand the applications which are running against it."
"Self-backup is the only feature lacking in this solution."
"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."
"The technical support has been a let down for us. It's something the company has to work on. We haven't been satisfied with their level of service."
"We did experience a little latency with this solution."
"In the future release, Huawei OceanStor should improve on what they already have. It is a good solution."
"The user interface is not so user friendly."
"The management is not a good feature in all of Huawei products. It's not easy or simple. Huawei has some problems with management and handling storage information from one interface."
"The administration should be simplified because there are a large number of options that make it too complicated, and the customers can get confused."
"The main concern is regarding the usability of the data storage."
"The duration of the built-in snapshot technology must be improved."
"Customization features must be improved."
"The deduplication and compression ratio is not very good. It's not reaching a very high ratio."
"The array level RAID does not seem available."
"The interface of this solution could be improved."
"Our model does not support compression or deduplication."
"The product needs to improve their scalability."
"Replication features need improvement. Currently, they are there in the product, but I'm not sure as to how it works exactly."
"We use some open-source tools for monitoring, such as Grafana and it should be bundled along with IBM FlashSystem."
