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

"One of the best features is the support, which is excellent."

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

"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."

"Its speed is superior to our existing Unity x00 model and it has performed substantially better than our x00 model and a little bit better than our x50 model."

"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 duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."

"One of the best features is the support, which is excellent."

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

More Everpure FlashArray X NVMe pros

More Everpure FlashArray X NVMe cons

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

"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."

"The monitoring matrix and its dashboard need work."

"The solution as it is right now is not very stable. The stability seems to have eroded."

"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."

More DDN IntelliFlash cons

"In HPE Alletra Storage, areas that have room for improvement include the network-attached storage, specifically the NFS performance."

"To improve HPE Alletra Storage, I suggest adding more expansion capabilities."

"The solution could use more monitoring of their split-brain system controllers."

"Speaking specifically of the 6K Alletra series, the renewal process can be complex due to the sheer volume of SKUs."

"The energy usage could be further improved."

"The power supply was not the correct power supply, and it took forever for them to send me the one that I needed. It took five months to get it."

"I would like to see more parallelism in the next release of HPE Alletra Storage."

More HPE Alletra Storage cons

Pricing and Cost Advice

"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."

"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."

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

"The support cost per array is about $20,000 a year for 24/7 support."

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

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

"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."

More Everpure 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."

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

"There is a license. HPE Alletra uses a cloud-based model."

"Its pricing is very competitive."

"It is reasonably priced."

"It is fairly priced. It is in line with industry standard pricing and cost models."

"So far, so good."
