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.

Quotes from Members

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

Pros

"The most valuable feature of this solution is reliability."

"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."

"The initial setup was extremely simple and straightforward."

"We are satisfied with the performance as it is significantly faster compared to traditional storage options."

"Everything, especially the VMs inside, is pretty fast."

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

"It has good, reliable, fast storage."

"It has benefited my organization because it has reduced time to insights."

More Pure FlashArray X NVMe pros

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

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

"Data Compression: Up to 80% space reduction in the database"

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

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

"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."

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

"The initial setup is straightforward."

More DDN IntelliFlash pros

"The most valuable feature of HPE StoreOnce is the virtual drive."

"The valuable feature is the ability to work with the Veeam software to reduce the backup windows."

"Recovery is important."

"The speed and deduplication ratio are two of the most valuable features of the solution."

"HPE StoreOnce is particularly useful in situations where organizations require a backup solution to store their data. Its deduplication feature is quite impressive, providing a deduplication ratio of around 25 to 26."

"Based on customer feedback, I rate it highly as one of the most stable products in the backup and archiving line compared to offerings like Data Domain or from Huawei and Lenovo."

"I like the tool’s deduplication feature. We get a ratio of 9:1 for deduplication. The product is also Linux based. Last year, our organization faced some virus attacks. However, the backup was safe because of the product being a Linux version. HPE StoreOnce is a secure product."

"The most effective features for data deduplication are maximizing storage capacity and minimizing expenditure."

More HPE StoreOnce pros

Cons

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

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

"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."

"The tool's pricing is higher than competitors."

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

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

"There is room for improvement in the pricing of the product."

More Pure FlashArray X NVMe cons

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

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

"Performance is horrible now. Our original intent was to buy new storage in about two years. But since it became a critical urgency for us, we decided to purchase a new one in two or three months."

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

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

"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."

"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."

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

More DDN IntelliFlash cons

"HPE StoreOnce could improve the capacity support."

"We're outsourced with a partner who recalls a larger amount of problems with the stability of the product."

"Its customer service could be faster."

"The repository should have an extension to connect to the cloud and deposit the backups."

"improvement? HPE StoreOnce has a limitation with respect to controllers. Other tools offer more than one controller. I feel that the high availability of the view controller should be redundant. The tool’s control and UI part should be improved and made more advanced. The feature that helps with the manual movement of tapes should also be improved."

"In terms of areas for improvement, I believe HPE StoreOnce could learn from competitors like Dell's Data Domain and ExtraHop in refining its architecture."

"The product's support is an area with certain shortcomings requiring improvements. Support needs to be faster."

"We archive our backups on tape, so I feel like if we could somehow plug our tape drive directly into the StoreOnce device and set it up to where it would archive based on, if some kind of rules based engine or what have you, that would really be an improvement for us."

Pricing and Cost Advice

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

"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."

"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 licensing is on a yearly basis."

"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."

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

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

More Pure FlashArray X NVMe pricing and cost advice

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

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

"The licensing costs is capacity-based and come bundled with support."

"The solution's cost is above average."

"With the same capacity of Data Domain and ExaGrid, which is 80 terabytes, HPE is the cheapest one."

"I rate the product's pricing a seven out of ten."

"The price puts me off. It's definitely on the high side."

"The cost of HPE StoreOnce is very expensive."

"There are costs for additional storage and space."

"The product is not expensive. It is available at a good price."
