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.

A highly stable solution that provides features like SmartMigration, HyperReplication, and SmartPartition

Other Huawei mid-end storages, like 5600 and 5500, are very easy to use. Engineers with two to three years of experience with Huawei will find that Huawei OceanStor Dorado is a bit complicated to use compared to other Huawei storages. Unlike other storages, you cannot configure the disk domain and storage pool in Huawei OceanStor Dorado.

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

"The most valuable features of this solution are its ease of use and performance."

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

"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."

"What I really like about this program, is that it is easy to use and easy to configurate."

"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."

"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."

"It has benefited my organization because it has reduced time to insights."

"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."

More Pure FlashArray X NVMe pros

"Two things really stand out for me. First, there's group cloning, which is very nice. It simplifies managing multiple clones across the group. Second, Huawei's multi-controller architecture with load balancing is a good part."

"The majority of our customers find this solution simple to use."

"The primary factors that make Huawei OceanStor Dorado Series highly valuable to us are its competitive pricing, exceptional performance, and stability."

"The support team is responsive and effective in addressing any issues that arise."

"I've been satisfied with the level of attention I'm given when I reach out to technical support."

"It is a scalable solution."

"This is a stable product that we can use for DR in production."

"The most valuable features of the solution are SmartMigration, HyperReplication, HyperSnap, HyperCopy, HyperClone, SmartPartition, and SmartCache."

More Huawei OceanStor Dorado pros

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

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

Cons

"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."

"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."

"They could add more support for file storage and different types of storage."

"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."

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

"The UI for this solution needs to be improved."

"We would like to see VNC integration or be able to use Pure Storage with VNC."

"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 Pure FlashArray X NVMe cons

"There are some limitations to this product because they do not have unified storage."

"Huawei OceanStor Dorado's biggest weakness is its lack of cloud integration."

"The user interface of Huawei OceanStor Dorado could be more user-friendly. Other solutions, such as EMC, have a better user interface."

"Difficult integration with third parties."

"The speeds of the disks themselves need to be faster. The disks are not flash. When we opened our hard drive from the inclusion, I saw a converter, and it's not entirely flash."

"Huawei should provide new security features, such as blocking ransomware sites and improving detection. Currently, we receive updates from HQ in China; there are instances where hackers may infiltrate network sites and encrypt our data."

"The solution needs to improve its integration."

"For future releases, it would be beneficial for OceanStor Dorado to integrate advanced analytics and AI-driven functionalities for predictive maintenance and performance optimization."

More Huawei OceanStor Dorado 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

"The tool's pricing is cheap; I rate it a six to seven out of ten. Most of our sales are not subscription-based. We sell the hardware, and customers keep using it. They only renew the service part annually. The support can be a bit pricey, but the solution is more cost-effective than anything else out there."

"As far as the licensing costs, everything is included in the license."

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

"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."

"They can tout the functionality and cutting edge technology that they have, but that's where the price tag comes in. The cost is high, but I think as they grow their business and get more customers that it will probably go down a little bit."

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

"Pure FlashArray X NVMe’s pricing is cheaper than other products."

"The support cost per array is about $20,000 a year for 24/7 support."

More Pure FlashArray X NVMe pricing and cost advice

"Huawei has very good pricing. They have some promotions that can be taken advantage of at certain times of the year, such as the end of December. They are providing aggressive pricing. In the Pakistan market, they are ready to beat any vendor in Pakistan because they want to grab the market."

"The solution's licensing structure needs improvement."

"There are some costs in addition to the standard licensing fees, depending on the requirements."

"This product is not too expensive, and the price is competitive on the market."

"There are lots of features included with this solution and some of them require additional licensing, such as creating high availability storage using a cluster."

"The pricing is one thing that works for them. I think their pricing is more competitively affordable than these top competitors."

"I rate the pricing a six on a scale from one to ten, where one is expensive, not cost-effective, and ten is cheap."

"It stands out as the fastest purpose-built storage solution available on the market, and the pricing is highly competitive and excellent."

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

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