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.
"There was a dramatic improvement in operating costs just as a result of the environmentals and space, let alone the cost of the unit itself."
"The performance of the storage is just unbelievable."
"We were actually able to do multiple upgrades, including head upgrades and moving between the platforms, M20 and M50, over the years. We have never once lost a ping and have never had an outage due to an OS upgrade or a complete head upgrade."
"I have seen a huge increase in speed and performance on our databases."
"Having fast storage allows actual servers to perform in high capacity so we don't have slowdowns on our applications."
"It is always out of the box, and ready to use."
"Because we were able to afford to go all flash, we don't manage the tiers, we're not moving data up, and we're not waiting for overnight cycles."
"The deduplication and compression rates are beyond impressive."
"It is easy to set up the solution."
"It has improved the utilization of our own internal resources and performance across our managed service platform, meeting our customers SLAs."
"The inline deduplication and data reduction capabilities have been the most valuable."
"The most valuable feature of Dell Unity XT is its support of protocols for both block, and file levels. It has the features a store solution should have."
"We particularly like the user interface on cloud IQ with this product."
"It is easy to scale, maintain, and manage."
"The hardware itself, it differs from Compellent and differs from the VNX before it. It doesn't have a separate file harbor that goes with it, there are no separate NAS heads. It's 2U, you have file and block storage, so you get a quite a lot of services for a small footprint."
"I like that the performance is very good."
"Huawei OceanStor provides numerous features that are tailored to cater to the requirements of all types of companies."
"The solution is easy to use."
"The solution is scalable."
"The most valuable feature is the availability."
"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."
"The solution works well for non-critical applications that do not require a heavy workload. The tool's all features are valuable."
"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."
"If they could make it cheaper, that would be something."
"A year ago they promised that they would be able to read through the database encryption with more metric and they have not delivered on that patch, which is significant because it gives us back so much more storage room. We want to be able to read through the encryption."
"I’d love to view the average, minimum and maximum performance in the reports (Analysis tab - Performance) but it is only graphics and you need to export data in CSV to find this information."
"I would like a feature to integrate with external or cloud solutions. For example, if I want to use this storage for a backup from the cloud, I want to have integration with the cloud vendors, such as Microsoft, Oracles, or Amazon. It could be available as an API to allow seamless integration. Additionally, the solution could improve by having native integration with a cloud provider, such as VMware or Microsoft, this would reduce the need to use third-party solutions to complete the task."
"I would rate this solution an eight because we have had outages. The commit times went very high in the database. The whole array went down so our customers were down for around eight hours. This was a very big outage which could have been our fault because we didn't do the upgrade in time."
"We need to add more storage in Pure Storage FlashArray with the cluster mode activated for us to have better performance."
"I feel like there is too much automation; the user doesn't have any manual input."
"Areas for improvement would be the financial operations. In the next release, I would like to see a NAS protocol included."
"In terms of what could be improved, I would say its capacity and its connection."
"There are a lot of things that can be done with it. It's got Cloud IQ, but I think it's not as mature as it could be, they could make it more effective. They could make it more comparable to some of the other products out there that have cloud analytics. The amount of insight that the Unity product is able to give, at this point, is okay, but not class-leading. Some of the other data-reduction technologies, like deduplication, are not to the level of other competitors and what their products provide."
"The iSCSI and the VMware integation using vSphere could be less confusing."
"Licensing has been quite difficult. It doesn't always auto-license. About half the time, when I provision one, I have to contact Service to get a license, or even go to our account manager to help get it straightened out."
"The pricing is a bit high. We'd like it to come down."
"The Host LUN ID is sequential by access in the hosts. When one LUN needs access by many hosts (for cluster purposes), in some cases the Host LUN ID remains different on each host."
"It should be lighter. It takes up a ton of rack space. It would be nice to have a smaller footprint."
"We went to the PowerMax because of the needs that we have for the business. We're doing true enterprise-level storage. So we went from Unity to PowerMax to give us that tier that we were looking for."
"Its storage capacity could be better."
"The speed has room for improvement."
"The upgrading process needs improvement. Deploy it and notify the customers when new versions and stuff comes out. I don't think they're doing that well."
"Technical support could be more helpful."
"The security could be a bit more robust."
"Its data replication features work slowly for nodes."
"Huawei is not that cheap."
"The main concern is regarding the usability of the data storage."
