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.
"Provides fast access and is user-friendly."
"It helps simplify storage. When you're running Pure all-flash, you don't have to do a lot of the old Oracle best practices. You don't have to worry about putting log files on a different disk channel than the data files, and those types of issues... That has made it vastly easier to do large volumes, rapid provisioning in databases, without taking a performance hit."
"The predictive performance analytics is a very good feature, as our system is performing better than before."
"The most valuable feature is how it simplifies the management of the SAN."
"The most valuable feature of Pure Storage FlashArray is the all-flash storage performance, low latency, and efficiency of their de-duplication technology. Additionally, the ease of use is good compared to other storage systems. The features in data protection, snapshotting, and replication between data centers and sites are superior to other solutions."
"The most valuable features of Pure Storage FlashArray are simplicity, ease of use, and dashboard management."
"Redundancy and the fault tolerance of the platform are the most impressive."
"It simplifies the overall management. We don't have to worry about storage anymore."
"The most valuable aspects of this solution are its stability, performance, and ease of updating."
"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."
"In the hybrid version, I would say they are fast. They have fully automated storage tiering. In the all-flash version, higher performance, compression, data replication."
"The feature that I have found most valuable is the unified storage. Also, its capabilities for block-access, file access, and the center box."
"I like the easy management with the new Unisphere management and the HTML5 interface."
"The storage management is superb, with a user-friendly graphical interface and dashboards. The performance is good. The integration, dashboards, and analytics are excellent. It gives me immediate output and quick access to the reports I need promptly. It's an excellent product with high stability. The solution is scalable. The support team is highly supportive, responsive, and efficient in providing solutions. This product is highly useful and well-suited for all types of automation."
"This product is perfect for small, and mid-range customers who need to pay less, but still, get enterprise-level capabilities."
"It does great deduplication. From a storage perspective, we save money being able to dedupe right on the disk"
"The most valuable feature is the availability."
"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 setup and the price are the most valuable and not the features related."
"The most valuable features of Huawei OceanStor are the dashboards, bandwidth, and data performance."
"Its technical support team is helpful."
"Excellent and efficient support, and the product is a good price."
"Great value for money."
"The solution is scalable."
"Part of our company works on Dell EMC because Pure Storage did not have synchronous applications when we were purchasing our products."
"We understand that they're thinking about it, but one of the things that would be nice is if they added some basic file-level capabilities to the platform. The idea is that they would run a basic NFS or CIF share from the controllers. FlashBlade is the powerhouse for File and Object storage, but if you don't need all that power, a lightweight file function would make FlashArrays more versatile."
"The connectivity needs improvement. You do not have the possibility to have a file and block connectivity at the same time on the same machine. It has limited ability to do so."
"Currently, the solution fails to support file screening."
"It would be nice if Pure had something in its portfolio that provided higher deduplication and compression for backups."
"We do have an issue with the vCenter integration. Pure Storage says it has a lot of free space, but vCenter says its completely full. This is because their dedupes are saved as space, but Vcenter still detects the disk as completely full. So, we do have an issue with that."
"We would like more extended historical data to help with some of the capacity planning. This is something that we are asking for all the time. E.g., what was the historical performance of this particular volume? So, we would like more historicals."
"There are many features which need to be added, particularly on the replication side."
"Compression and block deduplication on non-all-flash solutions."
"Replication with VMware - it's called the vSphere Metro Storage Cluster - is lacking in the Unity and is present in Compellent."
"We had some issues recently because of a bug in the system. We were presenting LANs to the Unity array but I think it caused a disruption to the host. EMC did acknowledge it and provided an alternative way to do it."
"We would like to see more advanced integration capability added to this solution."
"I would like it to be a little bit easier to contact support. We can contact support, but we have to go through a phone tree. We get routed to different places. I might call support to say that I need a drive replaced and get transferred to three different groups before I get to the group I actually need."
"Licensing costs could be reduced."
"It is expensive, and the pricing could be better."
"The support portal needs fixing. Accessing a service request on the support portal seems to be a bit difficult, as opposed to just calling the 800 number."
"Its storage capacity could be better."
"I would like to see the next generation all-flash, which could be combined."
"The product must improve the local technical support in China."
"The overall price of the solution should be reduced."
"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."
"Technical support could be more helpful."
"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 user interface is not so user friendly."
