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.

Data management operations are streamlined with impressive metrics and responsive support

Improving HPE Alletra Storage is challenging to answer because there are several different metrics to consider. From a performance perspective, the improvements and large jumps are fantastic as is. From a deployment perspective, I was a big fan of the on-premise deployment model and then connecting it afterward to GreenLake. Now that's being sunsetted. From a sensor and metric standpoint, there is just enough data without getting useless metrics, where you become blind to what it provides. The HPE Storage Technical Assistance Center is still probably the best out of all the storage vendors. It's difficult to improve upon being able to call in and get assistance almost instantly.

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."

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

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

"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."

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

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

"I appreciate the performance."

"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."

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."

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

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

"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"

"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."

More DDN IntelliFlash pros

"The greatest benefit we have seen is at the level of increased disk space and speed with the new features of the HPE Alletra Storage server."

"3PAR took it to another level, but Alletra and GreenLake have impressed me utterly and totally and made life easier."

"The overall redundancy and performance of the system is valuable."

"The deduplication feature is great."

"Performance-wise, you're looking at different models; a 6030 gives you more than a 6010, and a 6050 gives you more than a 6030."

"HPE Alletra Storage is simple."

"More deduplication and compression are valuable because capacity matters."

"Alletra has helped us reduce time spent on storage."

More HPE Alletra Storage pros

Cons

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

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

"We need better data deduplication."

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

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

"In the future, I would like to see integration with enterprise backup systems."

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

More Pure FlashArray X NVMe cons

"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."

"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."

"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."

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

More DDN IntelliFlash cons

"In my case, HPE Alletra Storage does not provide a cloud-like operational model on-premises for managing data infrastructure."

"HPE Alletra Storage could be improved by adding support for file-based or S3 storage, as we have NetApp as our NAS storage."

"I'd like the solution to offer more free training."

"I'm not sure if I've gone through all the features. There's always room for improvement."

"The challenge I face is that the recent models launched are not available now. When we pitch a solution to a customer and sell HPE Alletra 6000, the customer sees that the product has been discontinued by HPE."

"There were challenges initially, deploying it. I'm not sure there was an issue with compatibility between our ESX host connecting to storage, or something of that nature. However, we would constantly drop storage."

"We struggle to gain access to senior support engineers. Typically, we need to escalate via sales."

"Especially for smaller companies, it would be nice if there were more disk add-ons or incentives, such as 'If you buy our system with our forever warranty, you get new controllers every three years.'"

Pricing and Cost Advice

"The licensing is on a yearly basis."

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

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

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

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

"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."

"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
