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

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

"We are satisfied with the performance as it is significantly faster compared to traditional storage options."

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

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

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

"The solution is scalable."

"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."

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

More Pure FlashArray X NVMe pros

"The fast performance and reasonable pricing of Huawei OceanStor Dorado are the main reasons we sell them."

"The initial setup is straightforward. Deployment takes about a day."

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

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

"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."

"The installation and management are very easy."

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

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

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 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."

"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."

"There is room for improvement in the pricing of the product."

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

"The tool's portfolio is minimal. It is expensive."

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

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

"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."

More Pure FlashArray X NVMe cons

"This solution can improve by providing easier migrations and better Metro features."

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

"The built-in reporting tools need some enhancement."

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

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

"The product should be better aligned with the virtual environments"

"This solution does not support VMware VVols 2.0."

"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."

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

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

"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."

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

"The licensing is on a yearly basis."

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

"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."

More Pure FlashArray X NVMe pricing and cost advice

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

"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."

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

"You need to pay for the license."

"We usually recommend our customers choose advanced licensing and enterprise companies are more inclined to choose this solution because it is more cost-effective than competitors."

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

"The solution's licensing structure needs improvement."

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

More Huawei OceanStor Dorado 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."
