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.

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.

Quotes from Members

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

Pros

"It has good, reliable, fast storage."

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

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

"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."

"I appreciate the performance."

"The solution is scalable."

"The latency is good."

"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."

More Pure FlashArray X NVMe pros

"The initial setup is straightforward."

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

"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"

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

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

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

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

More DDN IntelliFlash pros

"The most valuable feature is the flexibility in the rail, as it is hybrid storage."

"The initial setup was straightforward."

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

"Stability: The product is designed to have always HA (High Availability) with redundant network and processors."

"Great value for money."

"This is a stable storage system."

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

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

More Huawei OceanStor pros

Cons

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

"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."

"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."

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

"I'd like to see the product implement active replication for vehicles such as VMware."

"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."

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

"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."

More Pure FlashArray X NVMe cons

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

"Snapshots are not as easy to access as on a NetApp device."

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

"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."

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

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

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

"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."

More DDN IntelliFlash cons

"Based on what we were quoted, the stated capacity was not a true reflection of the actual capacity."

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

"Integration with mainstream solution technologies could be better."

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

"They should introduce a feature to Huawei OceanStor similar to a storage controller, allowing for seamless integration of additional storage modules."

"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."

"The management is not a good feature in all of Huawei products. It's not easy or simple. Huawei has some problems with management and handling storage information from one interface."

"The duration of the built-in snapshot technology must be improved."

More Huawei OceanStor cons

Pricing and Cost Advice

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

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

"The licensing is on a yearly basis."

"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."

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

"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

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

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

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

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

"We pay a monthly licensing fee for this solution. The price could be less expensive."

"This product value matches its price."

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

"It's roughly affordable."

"Huawei OceanStor is a cost-effective storage solution."

"The product is cheap."
