We performed a comparison between Dell Unity XT and Huawei OceanStor 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, Dell Unity XT came out ahead of Huawei OceanStor. Both products have similar deployment difficulty and support quality, but Huawei OceanStor has more features that need improvement and can get expensive, depending on the chosen licensing.
"The solution is scalable."
"The high availability of the product is the most valuable feature."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"One of the best features is the support, which is excellent."
"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 latency is good."
"The initial setup was extremely simple and straightforward."
"With all-flash it should be able to scale. You probably just need one 4U device and you have terabytes of space."
"I don't think I've ever seen latencies above 10 milliseconds unless it was something that wasn't the array that was messing up. The thing is rock-solid."
"The setup and installation procedures are easy."
"I have had no problem at all. I think this is one of the most important things. It is very good. Maintaining it and deploying updates require very low maintenance. We haven't had problems. We had to replace a couple of disks in all these years, but it was pretty straightforward."
"This solution makes it easy to manage storage, provision new workloads, and scale-up."
"The product has helpful local technical support."
"For our customers, it's the simplicity of it. They find it easy to use, along with the added features, the dynamic volumes."
"The way it takes the Snaps, that is one of the best features. Snapshot performance is what is key in the Unity, compared to a traditional VNX."
"The most valuable features of Huawei OceanStor are the dashboards, bandwidth, and data performance."
"The most valuable feature of Huawei OceanStor is the hybrid applications."
"The solution is scalable."
"Great value for money."
"The most valuable feature is the flexibility in the rail, as it is hybrid storage."
"The most valuable feature is the availability."
"The support is excellent."
"OceanStor is cheaper than Dell EMC, and its management interface is quite simple."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"I'd like to see the product implement active replication for vehicles such as VMware."
"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."
"The tool's portfolio is minimal. It is expensive."
"The UI for this solution needs to be improved."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"In the future, I would like to see integration with enterprise backup systems."
"Unity only does compression. It would be nice if there was a deduplication feature as well. At my previous job, we used XtremIO and that was deduplication and not compression, and I think we got more out of it because the more OSs you have that are the same, the fewer copies it needs to keep of all that data. So, the deduplication would be a nice feature to have."
"We did encounter a firmware bug which actually caused loss of data. There was some heartburn around that. But in general, it has operated as expected, except for that bug."
"It could always use native replication. Then I could get rid of RecoverPoint."
"I would like the device to have the ability to pull down its own firmware. That would be a great thing."
"It's not as reliable as it should be, I think it was probably released a little early. We've had production problems with customers, and there are still some challenges at scale as well. Compression is a problem for the system. Once you enable dedupe and compression, the performance of the system, the capability, halves... It has to be right-sized and sized for compression, but even with that, because there are only two storage processors, you're ending up at almost 40 percent usage."
"I would like to see more integration with other products."
"Compression and block deduplication on non-all-flash solutions."
"Maybe deduplication would be something that would be better to have. Also, it's a fairly new management interface, so work is still being done on that. But compared to other vendors and previous EMC storage, the Unity is really good."
"The security could be a bit more robust."
"In the future release, Huawei OceanStor should improve on what they already have. It is a good solution."
"The solution needs to improve the compression side of the application."
"The product must improve the local technical support in China."
"The main concern is regarding the usability of the data storage."
"The speed has room for improvement."
"The overall price of the solution should be reduced."
"The administration should be simplified because there are a large number of options that make it too complicated, and the customers can get confused."
