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.
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."
"The latency is good."
"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."
"Technical support has been helpful and responsive."
"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."
"Purchasing; We worked with a sales rep to purchase our Unity."
"We're able to access it from just about anywhere, as long as we have access to a browser. That feature is really neat because sometimes we will go to a different data center or a different site, and if we need to access it to see a LUN or to see any type of storage, we can do that. That's one of the big takeaways with Unity."
"Unity's are more easily administrated, so we need fewer people to do the administration. We have less overhead because of that."
"We run about 100 virtual servers on it. We have about 100 users accessing the file shares from there, and I've seen no problem with that. We have about a 10GB backbone. Whatever we throw at it, it hasn't shown any sign of weakness or anything. It's been really good."
"The Unity XT box is very strong. It doesn't break. The MTBF time is very large so you don't have to worry about faults or outages in your operations."
"They have a Unity REST API that I use to automate some of the storage stuff. I'm just getting started with it, but it seems pretty easy to use."
"We use the solution for site recovery manager, DR, and endpoint penetration."
"Storage Snapshots have been really nice. They allow us to do backups without impacting our production workload that much. The scalability, the ability to add disks dynamically and adjust our workload as needed, has also been really helpful. That definitely makes my job easier. And the interface for managing Unity is very easy. The integrations between VMware Hypervisor and Dell EMC are top-notch, so it's been really easy to use and manage."
"The solution works well for non-critical applications that do not require a heavy workload. The tool's all features are valuable."
"The solution is easy to scale as needed."
"Excellent and efficient support, and the product is a good price."
"It is easy to use, deploy, communicate and manage this solution."
"The performance and ease of management are the most valuable features."
"Generally stable with good technical support."
"OceanStor is cheaper than Dell EMC, and its management interface is quite simple."
"The solution is easy to use."
"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."
"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 tool's pricing is higher than competitors."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"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."
"The UI for this solution needs to be improved."
"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."
"More integration with VMware would always be helpful, plugins that go directly into the vSphere management. A single pane of glass is always beneficial."
"The solution should include a free process in the HPE portal that uses serial numbers to verify that hardware is genuine."
"We are running VMware, and with the VNXe it was possible to restore. We're using Veeam for VMware backups and with the predecessor, it was possible to mount a backup or restore a backup from a storage snapshot. With the Unity 300, this is not possible."
"It is expensive, and the pricing could be better."
"Improve the interface and provide more management capability."
"Last (and I understand that it has a low chance of being implemented) the copy services currently are redirect on write. It would be great if the administrator could choose between redirect on write and copy on write, when configuring copy job."
"The one thing that we would look at would be if they were to expand the file level features, just to give us a balance or a tier between it and Isilon options out there, for unstructured data."
"Ordering is easy, but the processing site and working with those companies was difficult."
"Unfortunately, this product doesn't support Flash Disks, but it's IOPS capacity is a great compromise."
"The solution needs to improve the compression side of the application."
"Integration with mainstream solution technologies could be better."
"The security could be a bit more robust."
"Huawei OceanStor should work on its saturation level and should be able to take up more load. It should give the same performance that it gives at 20 or 30 percent load for 80 percent as well."
"The solution’s reporting could be improved."
"I would like to see more integration features with different platforms."
"Its data replication features work slowly for nodes."
