Jaehoon Oh

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.

Offers better price and features compared to its competitors

The technical support for the solution is very good. Huawei, in our region, has more than 2,000 employees in the office, and they mostly have post-sales engineers for storage, servers, and networks. Huawei also trains its partner engineers on the storage it offers. If a customer faces any problem, then a partner engineer will first resolve it. If an issue is not resolved in the tool, then Huawei engineers get involved, and the case gets lodged with Huawei's tech team, after whom a Huawei engineer will come. The partner, a tech team, and then a Huawei engineer get involved in the support process. I rate the technical support an eight out of ten.

Alan Powers

HPC CTO at a manufacturing company with 10,001+ employees

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.

"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."

"On a scale of one to ten, I rate Pure FlashArray as ten."

"The initial setup was extremely simple and straightforward."

"The most valuable features of this solution are its ease of use and performance."

"The setup and the price are the most valuable and not the features related."

"The solution is easy to use."

"If your virtual machine that resides on it completely fills the storage space, thanks to it's built-in function of all-zero data space reclamation, you just have to ask to System Engineer to run a zero-free on hosts (thin provisioned) and you will get more space instantaneously."

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

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

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

"The software layer has to improve."

"It feels more suitable for small and medium-sized businesses rather than enterprises."

"The UI for this solution needs to be improved."

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

"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."

"We need better data deduplication."

More Pure FlashArray X NVMe cons

"Technical support could be more helpful."

"The deployment took a little longer."

"When it comes to the technical support team, I feel that the response time is an area with certain shortcomings where improvements are required."

"The solution’s reporting could be improved."

"The security could be a bit more robust."

"The technical support has been a let down for us. It's something the company has to work on. We haven't been satisfied with their level of service."

"From a political perspective, there are issues selling Chinese brands to Western companies, as some may not be permitted to use them."

"Its storage capacity could be better."

More Huawei OceanStor 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 licensing is on a yearly basis."

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

"Its price could be better. It is not too expensive, but it is the high-end cost. It is kind of a Rolls-Royce. You pay a lot, but you get a lot out of it. So, the price pressure on the way down would be great, but at the end of the day, if you need to do the work, you just pay for it."

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

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

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

"The product is expensive."

"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 Huawei OceanStor should be less expensive. It is expensive at the moment."

"This product value matches its price."
