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.

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

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

"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."

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

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

"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 solution is scalable."

"The solution is very straightforward to set up."

"The latency is good."

More Pure FlashArray X NVMe pros

"Great value for money."

"The technology seems to be good, especially the performance on their all-flash storage."

"I find the scalability features of OceanStor valuable. Additionally, installation is easy, and it only requires one person to install it. Maintenance is also easy and not a big issue."

"The solution works well for non-critical applications that do not require a heavy workload. The tool's all features are valuable."

"Huawei OceanStor has the capability of SSDs, high-performance disks, and higher disk support."

"Huawei OceanStor is stable."

"Huawei OceanStor is easy to manage."

"The solution is easy to scale as needed."

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 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."

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

"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."

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

"We would like to see more visibility into garbage collection and CPU performance in the GUI."

"One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them."

"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."

"The software layer has to improve."

More Pure FlashArray X NVMe cons

"The solution needs to improve the compression side of the application."

"In the future release, Huawei OceanStor should improve on what they already have. It is a good solution."

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

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

"The user interface is not so user friendly."

"The main concern is regarding the usability of the data storage."

"Unfortunately, this product doesn't support Flash Disks, but it's IOPS capacity is a great compromise."

"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."

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

"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."

"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."

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

"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."

"The product is expensive."

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

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

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

More Pure FlashArray X NVMe pricing and cost advice

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

"The product is cheap."

"I am satisfied with the tool's pricing, which is in the middle. It is overpriced. I rate it an eight out of ten."

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

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

"Huawei's prices are very good compared to those of its competitors."

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

"The tool's pricing is competitive and affordable. It has the best possible pricing that we can get from Huawei. The prices are fixed and there are no additional costs."

More Huawei OceanStor 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."
