Customers always have their issues resolved promptly.
Pure has good storage.
Huawei took longer to respond and send a new device when something critical happened.
The support for NetApp AFF is comprehensive—not just the documentation for self-guided reading, but for simple questions, spare parts, or urgent needs, you can have a contract that enables delivery the next business day or within four hours, depending on your process requirements.
I have communicated with them, and they are effective and responsive.

It is highly scalable.
It is suitable for both medium-sized and enterprise businesses.
It hasn't broken down anytime in the last six to seven years, despite hurricanes, earthquakes, and power outages.
Huawei OceanStor is capable of scaling up to a few megabytes and is equipped to handle varied network protocols.
You can add more disks, more disk shelves, or migrate the data seamlessly.
I would assess the scalability of NetApp AFF as excellent in handling massive data volumes.
 

Stability Issues

Sentiment score
8.1

8.4
NetApp AFF is highly praised for its stability, reliability, and efficient non-disruptive operations, making it ideal for critical environments.
During the eight years, there have been no problems such as hardware failure or stopping.
I would rate the stability of the solution as a ten out of ten.
I would rate the stability of the product at seven out of ten.
Huawei OceanStor is stable and reliable for storage solutions.
Other than the data store running out of space, I haven't had any issues with the technology.
They have always been upgrading very fast and implementing patches to resolve these issues.
 

Room For Improvement

Pure FlashArray X requires cost-effective improvements in UI, integration, cloud features, multitenancy, analytics, backup, AI, and scalability.
Huawei OceanStor users face challenges with integration, support, performance, and pricing, suggesting improvements in various technical and operational areas.
NetApp AFF users seek improved setup, intuitive interfaces, robust third-party integration, and enhanced management and support features.
We would appreciate a built-in transparent failover in the next release to eliminate the need for a separate metro cluster.
I'm eagerly anticipating the roadmap's promise of introducing multiple controllers, which could significantly boost scalability and resilience.
We mostly rely on long-term releases. We don't need the most up-to-date features, but we need a reliable environment.
Huawei currently lacks a solution for high-performance AI, unlike other companies like DDN, WekaIO, or IBM BlueStore.
The stated capacity was not a true reflection of the actual capacity.
The GUI of ONTAP Command Manager could be better, but the CLI is perfect.
Our backup system, Commvault, has an amazing capacity to do compression and deduplication better than NetApp AFF by itself.
 

Setup Cost

Enterprise buyers see Pure FlashArray X NVMe as a justified premium investment due to performance and comprehensive licensing.
Huawei OceanStor offers competitive pricing and valuable features, though its licensing model may increase costs, yet remains cost-effective.
NetApp AFF offers competitive pricing, valued features, and flexibility, though some users find expansion costs concerning over time.
While the prices may be higher than those of other vendors, we see it as a market leader with benefits.
The support can be a bit pricey, but the solution is more cost-effective than anything else out there.
I would give it a nine out of ten in terms of costliness.
Huawei is priced competitively, encouraging companies to consider it over other products.
Huawei OceanStor's pricing is very aggressive, making it highly competitive.
NetApp support is cheaper than Dell support.
While it is not cheap, they have introduced a new series of AFF that are more affordable.
The licensing cost of the product is expensive, and when combined with support, it becomes quite costly.
 

Valuable Features

Pure FlashArray X NVMe offers exceptional performance, reliability, scalability, and seamless VMware integration, enhancing workload efficiency and user experience.
Huawei OceanStor offers scalable, high-performing storage with easy management, strong support, and competitive pricing for diverse business needs.
NetApp AFF offers high speed, low latency, and robust performance with advanced data management and seamless integration for storage solutions.
Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator.
The platform's robust features include excellent sustainability tracking, and a comprehensive dashboard offering insights into IOPS, bandwidth, performance, and virtual activities.
Its data compression feature is the best that we have ever seen.
Huawei OceanStor offers good IOPS and is reliable and energy-efficient.
The main selling point of Huawei OceanStor is its ability to handle all storage protocols, including block, file, and object.
You can even download the ONTAP simulator and deploy it on your virtualization platform and test almost all features.
Data reduction capabilities such as deduplication, compression, and compaction are standard features included with the license in NetApp AFF.
Two important features that NetApp AFF has are the performance and the capacity to save data against attacks in general or hardware failure.

Featured Reviews

Jaehoon Oh - PeerSpot reviewer
Supports efficient storage management through volume snapshots and offers reliable non-disruptive upgrades
I have no specific improvements to suggest for Pure FlashArray X NVMe at this time. The performance statistics could be enhanced. I can see the performance statistics in the Pure Storage console, but it does not show the performance by 4K byte unit. It displays IOPS and bandwidth, but IOPS is about real use, and I want to know how many IOPS are currently running in 4K byte units. I cannot see that IOPS because most storage systems report their performance by 4K byte unit. I want to see Pure Storage performance by 4K byte unit to compare with other storage or other internal NVMe SSD.
ChukwuemekaOnyemelukwe - PeerSpot reviewer
Uses a proprietary technology with simple interface and has easy deployment
If you are not generating a substantial amount of data, the available storage space might suffice, making scalability less of a concern. However, if your data generation increases and you require more storage, Huawei OceanStor offers solutions to expand your storage capacity. Expanding storage resources can involve additional costs and configuration efforts. Acquiring more storage solutions and ensuring their integration with your existing setup might require a significant investment of time and resources. While this process can be complex, it allows for seamless scalability as your data storage needs grow. I rate the solution’s scalability an eight out of ten.
KennethEtsula - PeerSpot reviewer
Offers seamless installation and efficient data handling with robust support
NetApp AFF provides an all-flash storage solution for unified SAN solutions, supporting both SAN and NAS functionalities. Data reduction capabilities such as deduplication, compression, and compaction are standard features included with the license in NetApp AFF. With the storage efficiency from a NetApp AFF installation, users can manage substantial data running on all-flash. The features such as compaction and compression provide storage efficiency guarantees in an all-flash environment.

NetApp vs. XtremIO
Is there another storage platform as feature rich as NetApp FAS? I think it is fair to say that NetApp FAS running Clustered Data ONTAP is a very feature rich platform – the move to the clustered version of ONTAP has brought many next-generation features including Scale-out and Non-disruptive…
