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.

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.

HPC CTO at a manufacturing company with 10,001+ employees

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

"It has good, reliable, fast storage."

"The best features of Pure FlashArray X NVMe include the volume snapshot capabilities, which allow us to save most of the storage space by volume snapshots periodically."

"We were able to save a ton of data center space with density ratios we've never seen before with hardware, and with Pure, we immediately saw value in the density ratios that we would be able to achieve, the performance, the scalability, and the support."

"I appreciate the performance."

"The solution is scalable."

"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."

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

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

More Everpure FlashArray X NVMe pros

"Pricing is very fair. It's competitively priced."

"The solution works well for non-critical applications that do not require a heavy workload. The tool's all features are valuable."

"OceanStor is cheaper than Dell EMC, and its management interface is quite simple."

"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 is scalable."

"Huawei OceanStor is stable and reliable for storage solutions."

"Huawei OceanStor offers good IOPS and is reliable and energy-efficient."

"The solution is easy to use."

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

"It is on the expensive side."

"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."

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

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

"I would like to see replication and DR features in the next release of this solution."

"Maybe the price can be reduced since the solution is very expensive."

"We've seen that when we create a POD in synchronous mode, it increases the latency."

"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 Everpure FlashArray X NVMe cons

"The speed has room for improvement."

"The configuration process is very complex, and the proprietary tools/software available for configuration are kind of tricky to install and run."

"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."

"Could have a more stable, lighter Metro and better logging system."

"The tool's performance is slow for DBs. We plan to move from Huawei OceanStor to Pure Storage. Its customer service is not good."

"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."

"In terms of marketing, they need to improve by putting more effort into making people aware of their products, especially in our region."

"The deployment took a little longer."

More Huawei OceanStor cons

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

"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

"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."

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

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

"The licensing is on a yearly basis."

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

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

"The tool is an investment that we've budgeted for. While the prices may be higher than those of other vendors, we see it as a market leader with benefits. We don't regret purchasing it."

"The product is expensive."

More Everpure FlashArray X NVMe pricing and cost advice

"The tool's pricing is competitive and affordable. It has the best possible pricing that we can get from Huawei. The prices are fixed and there are no additional costs."

"The product is cheap."

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

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

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

"Its price is affordable."

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

"Pricing is very fair."

More Huawei OceanStor pricing and cost advice

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

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