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.

Performance and interface improve data processing speeds but require complex configuration

The most valuable features of VMAX are its performance and GUI interface. We have seen significant improvements in technology over the last four to five years. The snap feature, along with deduplication, has notably enhanced our data processing speeds. We haven't experienced any outages or core-level issues in the last ten years, making us comfortable with the storage solution.

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

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

"What I really like about this program, is that it is easy to use and easy to configurate."

"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."

"The solution is very straightforward to set up."

"The best features of Pure FlashArray X NVMe include the volume snapshot capabilities, which allow us to save most of the storage space by volume snapshots periodically."

"Overall stability is very good. It is a very stable solution."

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

"The most valuable feature of this solution is its ease of use."

More Pure FlashArray X NVMe pros

"We haven't experienced any outages or core-level issues in the last ten years, making us comfortable with the storage solution."

"The product's initial setup phase was good."

"The ransomware protection feature is housed in a separate unit, specifically addressing the top twenty most critical threats."

"It works very well."

"The snapshot feature has been precious for our testing processes, application development, and managing testing environments due to its efficiency and ease of use."

"The most valuable features of VMAX are its performance and GUI interface."

"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."

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

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

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

"It is a highly available product."

More Huawei OceanStor pros

Cons

"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."

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

"In the next release, I would like to see real-time analytics for further insight into consumption models."

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

"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."

"It is on the expensive side."

"I would like to see replication and DR features in the next release of this solution."

More Pure FlashArray X NVMe cons

"The scalability of VMAX is somewhat limited, especially in terms of cache scalability."

"There is room for improvement in the centralized administration."

"The configuration part of the product is an area with certain shortcomings where improvements are required."

"The scalability of VMAX is somewhat limited, especially in terms of cache scalability. We've had to procure additional engines to address this limitation."

"Improvements are needed in both partition recovery and scalability."

"We encountered some challenges during large data migrations that could be addressed for smoother transitions."

"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."

"Huawei is not that cheap."

"Huawei OceanStor should work on its saturation level and should be able to take up more load. It should give the same performance that it gives at 20 or 30 percent load for 80 percent as well."

"The user interface is not so user friendly."

"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."

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

"The solution could improve by having better integration."

Pricing and Cost Advice

"The product is expensive."

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

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

"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."

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

"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."

"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."

"The licensing is on a yearly basis."

More Pure FlashArray X NVMe pricing and cost advice

"It is not a cheap product."

"The price falls within the mid-range, neither inexpensive nor high-priced."

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

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

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

"The price of the license is quite low, so it's not something special or expensive."

"The pricing depends on the features the customer wants, such as storage, RAM, and processors, but in general, Huawei is much cheaper compared to Dell and Cisco."

"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 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."

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