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.

Provisioning and encryption ease improve data storage efficiency

To improve HPE Alletra Storage, it needs to have a true active-active controller; it claims to have an active-active controller from the back end, however, the second node is pretty much sitting there doing nothing. The MV 10000 series, which is the next series, is an improvement to HPE Alletra, and HPE is already doing that. In the next release, I would prefer to see better dedupe features; I know other companies do excellent dedupe, and they have protection group policies, meaning you have immutable data in case of a ransomware attack. If you're on the SAN, it should give you a way to protect that data without being erased. Other vendors have that capability built-in, ensuring that you can't erase the data, so features similar to that would be great.

Quotes from Members

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

Pros

"The solution is scalable."

"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."

"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."

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

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

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

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

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

More Pure FlashArray X NVMe pros

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

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

"The initial setup is straightforward."

"It performed great originally, and when it performed great, it was awesome."

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

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

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

More HPE Alletra Storage pros

Cons

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

"They could add more support for file storage and different types of storage."

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

"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."

"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."

"The software layer has to improve."

"The tool's portfolio is minimal. It is expensive."

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

More Pure FlashArray X NVMe cons

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

"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."

"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."

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

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

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

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

"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."

More DDN IntelliFlash cons

"I'm going to skip discussing how HPE Alletra Storage can be improved as I'm not in the technology area right now and haven't paid attention to that."

"HPE Alletra Storage pricing can be improved. The pricing, licensing, and software have changed."

"I'd like to see larger cluster sizes beyond four nodes."

"To improve HPE Alletra Storage, it needs to have a true active-active controller; it claims to have an active-active controller from the back end, however, the second node is pretty much sitting there doing nothing."

"The deployment was a little rocky."

"HPE can improve HPE Alletra Storage by adding some features to be available from the offline GUI, especially related to snapshots and taking a snapshot for the whole storage, as some customers need this feature."

"A negative aspect would be that I can only get pool utilization from InfoSight, not on the local array. I have to pull metrics every month from InfoSight, and it would be easier if it were just available on the local array."

"I do not have any issues with it. It has been good for us. There are no cons that I see, and that is why we use it."

Pricing and Cost Advice

"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."

"The licensing is on a yearly basis."

"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."

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

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

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

"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."

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

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 solution is expensive and can cost around five lakhs."

"So far, so good."

"For us, its price is good."

"The main competitor in the market for HPE Alletra Storage is Dell Storage, as they are selling at a low price."

"Overall, it was good. It had a good price per gigabyte."

"HPE was a clear winner on price per terabyte. It was very smooth."

"Its price can be optimized."

"The pricing is somewhat high, but when customers choose HPE, they often prioritize the brand value over pricing. The pricing is higher compared to other vendors."
