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.

Performance and interface improve data processing speeds but require complex configuration
The most valuable features of VMAX are its performance and GUI interface. We have seen significant improvements in technology over the last four to five years. The snap feature, along with deduplication, has notably enhanced our data processing speeds. We haven't experienced any outages or core-level issues in the last ten years, making us comfortable with the storage solution.

Data reduction capabilities such as deduplication, compression, and compaction are standard features included with the license in NetApp AFF. With the storage efficiency from a NetApp AFF installation, users can manage substantial data running on all-flash. The features such as compaction and compression provide storage efficiency guarantees in an all-flash environment.

Quotes from Members

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

Pros

"Everything, especially the VMs inside, is pretty fast."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"We are satisfied with the performance as it is significantly faster compared to traditional storage options."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"The solution is scalable."
"The most valuable feature of this solution is its ease of use."
"The initial setup was extremely simple and straightforward."
"The product's initial setup phase was good."
"It works very well."
"The snapshot feature has been precious for our testing processes, application development, and managing testing environments due to its efficiency and ease of use."
"We haven't experienced any outages or core-level issues in the last ten years, making us comfortable with the storage solution."
"The ransomware protection feature is housed in a separate unit, specifically addressing the top twenty most critical threats."
"The most valuable features of VMAX are its performance and GUI interface."
"​It supports our virtualization, our VMware environment."
"The most valuable features of the solution are speed, performance, and reliability."
"This solution has reduced our data center costs because when we went from the 8000 and 3200 series that took us from 20 racks of storage down to two."
"Scalability is excellent. If we need more space, it's a no downtime solution. It's harder to get the funding than it is to get the solution itself."
"The initial setup was straightforward."
"We are using the AQoS operating system, which allows us to get a lot more out of our AFF systems."
"AFF helps us improve performance for our enterprise applications, data analytics and VMs. We have moved our primary data stores for production over to AFF, and a lot of the problems that might happened have gone away."
"With the storage efficiency from a NetApp AFF installation, users can manage substantial data running on all-flash, and the features such as compaction and compression provide storage efficiency guarantees in an all-flash environment."
 

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."
"In the future, I would like to see integration with enterprise backup systems."
"We need better data deduplication."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"There is room for improvement in the pricing of the product."
"I would like to see replication and DR features in the next release of this solution."
"There are some challenges with data encryption and reduction."
"Adding some functions to the product would be beneficial."
"The scalability of VMAX is somewhat limited, especially in terms of cache scalability."
"We encountered some challenges during large data migrations that could be addressed for smoother transitions."
"Improvements are needed in both partition recovery and scalability."
"The configuration part of the product is an area with certain shortcomings where improvements are required."
"There is room for improvement in the centralized administration."
"The scalability of VMAX is somewhat limited, especially in terms of cache scalability. We've had to procure additional engines to address this limitation."
"The size of NetApp could be better. They're always about 40 pounds without the hard drives in them, so it would be great if there's a way to make them smaller yet keep the functionality. That would reduce the physical footprint."
"I do not like the NetApp GUI. For example, the GUI of ONTAP Command Manager could be better, but the CLI is perfect. With every new version and upgrade, they change things, which makes it messy, and I am not good at working with that."
"I need faster Fibre Channel over Ethernet. They top out at 10GBs today and I would like that to go to 40 or 100."
"NetApp AFF needs to focus more on block storage. It has to focus on high-end, performance-driven applications."
"Sometimes, NetApp support could be better. When the customers escalate, it can feel like everything's starting from scratch. These are rare cases. I'm not directly involved in support, but that's what I hear when something doesn't work."
"The total cost of ownership has increased a little."
"It has not reduced our data center costs. NetApp charges a pretty penny for their stuff."
"In the past, NetApp designed it so that you have a 70% threshold. You would never fill up past 70% since you need to have that room available. Whereas with Pure, I can fill it up to 110% of what they listed and it's still going at full speed. NetApp can't do that."
 

Pricing and Cost Advice

"As far as the licensing costs, everything is included in the license."
"Our licensing fees are $500,000+ USD."
"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 licensing is on a yearly basis."
"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."
"With VMware, we pay $300,000 annually."
"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."
"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."
"It is not a cheap product."
"The price falls within the mid-range, neither inexpensive nor high-priced."
"I find the pricing to be reasonable, particularly with the recent inclusion of features like snap locking and ransomware protection within the ONTAP license instead of having them as separate licenses."
"The stability of AFF alone has been a significant ROI."
"The pricing is pretty reasonable for what we get. But if you have to buy any more disk space, it can be quite expensive."
"Our TCO has increased by 15 to 18 percent."
"It definitely reduces costs because it simply takes less power to run these systems. While the SSDs don't take power, they are in general very big right now. So, the running cost has decreased for a lot of our customers."
"NetApp AFF is an expensive product, although not compared to other vendors."
"Other vendors may come in at a cheaper price point, but you will pay in the end with management costs and downtime."
"There is room for improvement when it comes to the cost. The cost is very high compared to other devices."

NetApp vs. XtremIO
Is there another storage platform as feature rich as NetApp FAS? I think it is fair to say that NetApp FAS running Clustered Data ONTAP is a very feature rich platform – the move to the clustered version of ONTAP has brought many next-generation features including Scale-out and Non-disruptive…
