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.

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.

Cons

"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."

"Adding some functions to the product would be beneficial."

"We would like to see VNC integration or be able to use Pure Storage with VNC."

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

"We would like to see more visibility into garbage collection and CPU performance in the GUI."

"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."

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

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

More Pure FlashArray X NVMe cons

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

"I would like to see some form of direct connect fiber channel options."

"We had a hiccup when we deployed our last SAN. The 6000 that came in, they were transitioning the onboarding to be fully cloud, GreenLake-driven. The problem was we're in a regulated air-gapped environment."

"We had some issues while installing it on our servers. It required more resources while cross-checking. So, the initial setup process could be better."

"There can be more visibility and statistics for the customers to see. The customers would love to see AI."

"Due to their acquisition of Nimble, there are multiple portals. I'm hoping that that gets cleaned up."

"HPE has come out with the essential part of a new feature, and I would like to see that completely implemented in the next release."

"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."

More HPE Alletra Storage cons

"The tool's architecture is complex. It also needs to add data utilization reports."

"The solution's compression needs to be improved, as it's not the best."

"The solution's compression feature could be better."

"In the FlashSystem 5200, there were only four ports of 32 fiber channels for the architecture. This has been resolved in the new generation."

"The efficacy of the GUI in IBM FlashSystem 9100 NVMe could be enhanced, and it would be beneficial to include a feature that can prevent ransomware attacks."

"IBM's support is not good. I experienced a big problem where I opened the console IBM Storage and would see that something was broken. I called the call centers, and I said, "I have a problem. My drive is not working." They want me to give them the serial number, I gave it to them and they told me "I cannot find your product. Your product is not here.""

"I would like to see IBM products become more affordable because they can be quite expensive, which limits their accessibility to a broader customer base."

"The pricing should be more competitive."

Pricing and Cost Advice

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

"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."

"The product is expensive."

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

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

"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."

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

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