Chief Technology Officer at Lambda256

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.

Good customer service and support and suitable for large environments

It is very easy to install. Users don't need to remember anything while deploying IntelliFlash because everything will be taken care of by tech support. They can easily modify the installation or change the password with the help of the tech support. It is very easy to integrate IntelliFlash with other solutions. We have plugins that can be integrated with other solutions. It will require maintenance. It is the same as any other storage solution: updates and upgrades, firmware upgrades, and drive upgrades.

Cloud Architect at ESDS Software Solution Pvt Ltd.

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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

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

"The latency is good."

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

"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."

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

"The solution is very straightforward to set up."

"The solution uses newer technology for deduplication and compression."

"The most valuable feature of this solution is reliability."

More Pure FlashArray X NVMe pros

"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"

"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."

"High performance and ease-of-management are the most valuable features."

"It provides a combination of all the protocols that you need, without losing deduplication and compression."

"It performed great originally, and when it performed great, it was awesome."

"We use IntelliFlash products for larger environments, like Qatar Airways."

"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."

"Data Compression: Up to 80% space reduction in the database"

More DDN IntelliFlash pros

"Huawei has more features than other vendors. It integrates well with security management solutions, though not directly with databases."

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

"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 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 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 performance is good."

"The solution is scalable."

"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

Cons

"In terms of what needs improvement, the dashboard and management could be simplified."

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

"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."

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

"The software layer has to improve."

"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."

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

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

More Pure FlashArray X NVMe cons

"We had just one small stability problem with power flapping and it did not start up again automatically. We had to access service ports and manually restart the storage processors."

"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."

"It only keeps one hour of real-time data without the ability to do deep analysis of each element."

"Performance is horrible now. Our original intent was to buy new storage in about two years. But since it became a critical urgency for us, we decided to purchase a new one in two or three months."

"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."

"In the proxy section you can’t choose a user account and password, so it is not allowed at the moment to go out, if customer has such constellation."

"In future releases, I look forward to more AI features."

"It's somewhat scalable, but maybe not so much as some of the competition."

More DDN IntelliFlash cons

"The initial setup was very complex."

"The product could always be faster."

"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."

"I would really like to see Heterogeneous Storage Virtualization in a future release."

"Difficult integration with third parties."

"The price must be improved."

"The solution needs to improve its integration."

"The localization problem needs to be improved."

Pricing and Cost Advice

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

"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."

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

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

"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."

"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."

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

"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."

More Pure FlashArray X NVMe pricing and cost advice

"I recommend the full bundle software in order to have all the functionality. It is more expensive to purchase it one by one."

"I think we pay around 100 grand per year for three arrays or four arrays."

"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."

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

"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."

"The solution's licensing structure needs improvement."

"The pricing is very competitive."

"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."

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

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