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.

Mesh connectivity and load balancing ensure consistent performance and reduced I/O interruptions

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. Unlike other storage systems that rely on active-passive or active-active controllers, which can experience downtime during maintenance, OceanStor Dorado supports more than two controllers, allowing for seamless maintenance without impacting I/O operations. We even tested this by pulling out a controller during peak I/O time, and the system handled it flawlessly – no errors, no disruptions. That's simply unmatched in my experience.

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 solution is very straightforward to set up."

"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."

"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."

"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 database workloads are pretty fast because I frequently move data from here to there."

"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."

"The high availability of the product is the most valuable feature."

"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."

More Pure FlashArray X NVMe pros

"We can use Huawei OceanStor Dorado capacity storage for many different purposes."

"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."

"It is a scalable solution."

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

"Most of the features which all enterprises storages solutions have are available in Huawei OceanStor Dorado."

"The product has the best compression and encryption features. The most valuable features I have found in the tool are its performance and cost-effectiveness. While Huawei OceanStor Dorado may not always be chosen for its features compared to other brands like Dell, HPE, etc., it is often selected due to its affordability. Customers opt for Huawei OceanStor Dorado primarily because it offers similar performance features as other brands at a lower cost."

"The most valuable features are the five chips architecture and the purpose-built NVMe hard disk drive. Additionally, the IOPS feature is good."

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

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

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

"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."

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

"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."

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

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

"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."

More Pure FlashArray X NVMe cons

"They should add a feature to the platform to help us manage storage communication with one of the vendors."

"One of the key areas that need enhancement pertains to the software procurement process."

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

"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."

"In additional features, it would be easier to do snapshots on a regular basis. So, like, a new feature that would allow you to take snapshots every hour."

"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 product should be better aligned with the virtual environments"

"The initial setup was very complex."

More Huawei OceanStor Dorado 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."

Pricing and Cost Advice

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

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

"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."

"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 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."

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

More Pure FlashArray X NVMe pricing and cost advice

"The pricing is very competitive."

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

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

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

"The price of the solution is competitive compared to others, such as Dell EMC and Hitachi. I believe the reason they are providing a discount is they want to increase their penetration into 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 is more affordable than the competitor solutions"

"The price of the solution is reasonable. There is not a vendor that offers an All-Flash Storage Array at the price of Huawei OceanStor Dorado. The other solutions are approximately 50% higher."

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."
