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

"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."

"The initial setup was extremely simple and straightforward."

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

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

"Technical support has been helpful and responsive."

"The latency is good."

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

More Pure FlashArray X NVMe pros

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

"The solution’s overall security is good."

"The solution's pricing is its most valuable feature."

"The platform’s most valuable features are speed, accuracy, and encryption."

"The initial setup is very straightforward."

"The performance is good."

"Huawei OceanStor Dorado is fast and has significantly improved data storage efficiency."

"The most valuable feature for me is that it deduces better, whereby it can be assigned six times the usable capacity, depending on the nature of the data."

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

"Adding some functions to the product would be beneficial."

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

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

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

"It is on the expensive side."

"The tool's pricing is higher than competitors."

"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."

"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."

More Pure FlashArray X NVMe cons

"This solution does not support VMware VVols 2.0."

"The data compression and deduplication ratio of Huawei OceanStor Dorado is not as good as other solutions, such as EMC and Pure Storage. It is important when looking at capacity effectiveness."

"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."

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

"The initial setup was very complex."

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

"The solution needs to improve its integration."

"Huawei OceanStor Dorado could improve the integration, there have been some compatibility issues with some operating system functions."

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

"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."

"The product is expensive."

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

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

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

"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."

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

More Pure FlashArray X NVMe pricing and cost advice

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

"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."

"We saw ROI in terms of both money and time saved. It is worth the price."

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

"It's not easy to receive an upgrade license of Huawei OceanStor Dorado. It's easy to buy OceanStor with several features, but when you want to add on features later it's not easy. I had some problems."

"Huawei OceanStor Dorado has a competitive price compared to other solutions."

"In price comparisons with alternative products, it stands out as a more cost-effective option."

"It is an expensive solution."

More Huawei OceanStor Dorado 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."
