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.

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

"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."

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

"The initial setup was extremely simple and straightforward."

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

"The tool's valuable features are speed, security, data compression, and reliability. Its data compression feature is the best that we have ever seen. It helps us to save money and resources."

"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."

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

"The most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."

More Pure FlashArray X NVMe pros

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

"The solution is easy to scale as needed."

"The main selling point of Huawei OceanStor is its ability to handle all storage protocols, including block, file, and object."

"Huawei is much cheaper compared to Dell, offering a competitive price that makes companies consider their options."

"Huawei OceanStor provides numerous features that are tailored to cater to the requirements of all types of companies."

"Huawei OceanStor is stable."

"The initial setup was straightforward."

"We get a quick response in case any component defaults. We have seen the benefits mostly."

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

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

"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."

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

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

"I would like to see some AI features that would allow arrays to intelligently identify threats or unusual behavior in the data pattern and give an alert."

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

"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."

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

More Pure FlashArray X NVMe cons

"Technical support could be more helpful."

"The overall price of the solution should be reduced."

"Integration with mainstream solution technologies could be better."

"I would like to see more iterations and direct integration with other solutions."

"The deployment took a little longer."

"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."

"Huawei currently lacks a solution for high-performance AI, unlike other companies like DDN, WekaIO, or IBM BlueStore."

More Huawei OceanStor 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

"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."

"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."

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

"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."

"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."

More Pure FlashArray X NVMe pricing and cost advice

"The price of the solution could be less expensive. However, there are not any licensing costs."

"This product value matches its price."

"Payment is determined by the amount of storage capacity required, and we have paid 50,000 euros for our usage."

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

"Pricing is very fair."

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

"It's roughly 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."

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."
