Helps to save money and resources with the data compression feature

One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them. One way to improve the product is to add an operational assistant that doesn't depend on VMware. It could also establish more alliances with other operational systems.

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.

Stability-wise, a device that has been up and running for years

The failover capability and resiliency are some of the solution's valuable features. The big thing is resilience because it has richer coding in it, so multiple devices can't fail. Also, one can still access a number of CBoxes that can allow one to access their file system. Once a device fails, it fails the transparency of the end-user, and it just starts using another resource. The encryption capability, the snapshots, along with a whole bunch of features make the tool valuable. VAST Data keeps adding more and more features all the time.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"One of the best features is the support, which is excellent."

"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."

"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 solution uses newer technology for deduplication and compression."

"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."

"The most valuable feature of this solution is its ease of use."

"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."

"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."

More Pure FlashArray X NVMe pros

"Generally stable with good technical support."

"It is a highly available product."

"Stability: The product is designed to have always HA (High Availability) with redundant network and processors."

"The main selling point of Huawei OceanStor is its ability to handle all storage protocols, including block, file, and object."

"The pricing is very reasonable."

"Excellent and efficient support, and the product is a good price."

"The solution is easy to scale as needed."

"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."

More Huawei OceanStor pros

"This has been one of the most reliable storage systems that I have ever used."

"The solution is useful for machine learning and scientific applications, including computer simulations."

Cons

"I would like to see some AI features that would allow arrays to intelligently identify threats or unusual behavior in the data pattern and give an alert."

"There are some challenges with data encryption and reduction."

"We would like to see more visibility into garbage collection and CPU performance in the GUI."

"I'd like to see the product implement active replication for vehicles such as VMware."

"In the future, I would like to see integration with enterprise backup systems."

"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."

"In the next release, I would like to see real-time analytics for further insight into consumption models."

"The software layer has to improve."

More Pure FlashArray X NVMe cons

"The overall price of the solution should be reduced."

"Unfortunately, this product doesn't support Flash Disks, but it's IOPS capacity is a great compromise."

"Technical support could be more helpful."

"From a political perspective, there are issues selling Chinese brands to Western companies, as some may not be permitted to use them."

"They should introduce a feature to Huawei OceanStor similar to a storage controller, allowing for seamless integration of additional storage modules."

"I would like to see more iterations and direct integration with other solutions."

"The user interface is not so user friendly."

"Based on what we were quoted, the stated capacity was not a true reflection of the actual capacity. The data store ran out of space, and Huawei had to send a new unit."

More Huawei OceanStor cons

"The read/write ratio is an area in the solution with some flaws and needs improvement."

"The write performance could be improved because it is less than half of the read performance."

Pricing and Cost Advice

"With VMware, we pay $300,000 annually."

"Pretty much everything that you need is licensed when you buy the product. Licensing to me is different than the maintenance cost, but they can bleed into one another. We buy the product, and we expect three years of support bundled into what we negotiate on our storage arrays. I would start to see maintenance costs going into the fourth year, but we're not there yet."

"The licensing is on a yearly basis."

"Given its price, Pure is not the first option."

"Our licensing fees are $500,000+ USD."

"We pay approximately $50,000 USD per year in licensing fees."

"The product is expensive."

"With Pure Storage, we would like to continue seeing price reductions with flash storage. I don't think we're any different than anybody else when we continue to look to the industry for price reductions of both NVMe and traditional SSD storage. We would like to see these prices continue to decline and erode, even displacing large spinning disks."

More Pure FlashArray X NVMe pricing and cost advice

"The price of the license is quite low, so it's not something special or expensive."

"Overall, the solution's pricing was cheaper."

"The pricing depends on the features the customer wants, such as storage, RAM, and processors, but in general, Huawei is much cheaper compared to Dell and Cisco."

"I am satisfied with the tool's pricing, which is in the middle. It is overpriced. I rate it an eight out of ten."

"Huawei's prices are very good compared to those of its competitors."

"Huawei OceanStor is priced very well but is a bit complicated."

"Payment is determined by the amount of storage capacity required, and we have paid 50,000 euros for our usage."

"Huawei OceanStor is a cost-effective storage solution."

More Huawei OceanStor pricing and cost advice

"We acquired VAST Data as a one-time, capital purchase."

"Price-wise, VAST Data is not the cheapest, not the most expensive one."
