We also had one outage where a controller of one of the products had failed and had to be replaced on-site.
Customers always have their issues resolved promptly.
The support for NetApp AFF is comprehensive—not just the documentation for self-guided reading, but for simple questions, spare parts, or urgent needs, you can have a contract that enables delivery the next business day or within four hours, depending on your process requirements.
Sometimes, the support was inadequate because the initial architecture was poorly defined.
We are also using it ourselves for the SAN and CIFS protocol.
They often provide basic solutions, such as suggesting a failover or a power cycle, which are not the sophisticated solutions we expect from a vendor.

During the eight years, there have been no problems such as hardware failure or stopping.
I would rate the stability of the solution as a ten out of ten.
I would rate the stability of the product at seven out of ten.
They have always been upgrading very fast and implementing patches to resolve these issues.
When panic occurs on the node, it reboots itself, and we have experienced numerous hardware-related issues.
 

Room For Improvement

Pure FlashArray X requires cost-effective improvements in UI, integration, cloud features, multitenancy, analytics, backup, AI, and scalability.
NetApp AFF users seek easier setup, enhanced management, lower latency, better support, improved documentation, and cost-effective, scalable solutions.
NetApp FAS Series needs enhancements in flexibility, pricing, integration, performance, documentation, support, virtualization, and scalability to address user concerns.
Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe.
We would appreciate a built-in transparent failover in the next release to eliminate the need for a separate metro cluster.
I'm eagerly anticipating the roadmap's promise of introducing multiple controllers, which could significantly boost scalability and resilience.
The GUI of ONTAP Command Manager could be better, but the CLI is perfect.
Our backup system, Commvault, has an amazing capacity to do compression and deduplication better than NetApp AFF by itself.
Nutanix leads the business in this approach, and I feel that NetApp is missing some aspects, such as CPU, GPU, and RAM, in its AI portfolio.
There is an opportunity there for NetApp with Cloud Volumes ONTAP.
It was not possible to have a custom user inside ONTAP without the delete permission to delete the volume.
 

Setup Cost

Enterprise buyers see Pure FlashArray X NVMe as a justified premium investment due to performance and comprehensive licensing.
NetApp AFF pricing varies widely, viewed as expensive yet cost-effective, with negotiation impacting affordability and overall value justifying costs.
NetApp FAS Series is pricey but offers good ROI and savings through bundled licensing, with support impacting overall costs.
While the prices may be higher than those of other vendors, we see it as a market leader with benefits.
The support can be a bit pricey, but the solution is more cost-effective than anything else out there.
Pure FlashArray X NVMe’s pricing is cheaper than other products.
NetApp support is cheaper than Dell support.
While it is not cheap, they have introduced a new series of AFF that are more affordable.
The pricing of NetApp FAS Series is not cheap, but in comparison to other vendors, NetApp FAS Series is affordable.
 

Valuable Features

Pure FlashArray X NVMe offers exceptional performance, reliability, scalability, and seamless VMware integration, enhancing workload efficiency and user experience.
NetApp AFF excels with efficiency, seamless ONTAP integration, ease of use, high availability, low latency, and real-time replication.
NetApp FAS Series excels in high availability, integration, and efficient storage solutions, featuring robust disaster recovery and unified storage.

The platform's robust features include excellent sustainability tracking, and a comprehensive dashboard offering insights into IOPS, bandwidth, performance, and virtual activities.
Its data compression feature is the best that we have ever seen.
You can even download the ONTAP simulator and deploy it on your virtualization platform and test almost all features.
Two important features that NetApp AFF has are the performance and the capacity to save data against attacks in general or hardware failure.
While NVMe disks are expensive and require three disks for parity calculations, hard drives in NetApp FAS Series are inexpensive, making it more cost-efficient per GB, even with RAID tech implementation.
One important feature for customers is its ease of use and continuity, enabling seamless usage across on-premise and cloud environments.
At this moment, autonomous ransomware protection is the key feature.

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.

Flexible with great support and high-speed multi-protocol storage
Keystone offers flexible consumption models that go beyond just how much capacity at such and such a speed, et cetera. We don't always know what the profile of that data will be. However, if we can quickly agree on terms that meet our needs and make NetApp still reasonably profitable, we can confidently deploy, see how things go and adjust. That kind of service delivery model, that customer service model has sped things up and made contract negotiations much easier. It frankly made the owners of the system more confident. We've experienced faster time to market. It's hard for us to find and retain infrastructure staff. We're in a business where the firm fixed price contract reigns supreme, and so we can't always just offer someone more money. However, if they can dedicate their time to learning one company's portfolio and learning it really well, but be useful in a bunch of different places, they will do well. We've seen that in a lot of different places. We've been able to hire younger people and retain them, moving them from program to program based on their understanding of the solution its skill set, and its portability. It's been useful for high-speed multi-protocol storage in places with ever-increasing density. We have limits on how much power and cooling and rack space we have, and yet they've delivered every time. We needed a storage company that had mastery of multi-protocol, and this solution stands out. They especially stand out as a secure provider. We require solutions that we can run ourselves, that we can air gap since so much of what we do is either classified or very sensitive or cannot live in a public ecosystem. For us, the issue consuming AI has been the trust of the models given to us by third parties. We can't necessarily trust their provenance, what fed them, what originally trained them, or what gave them their worldview, for lack of a better term. We can't simply just trust that at face value since we know nothing about where it came from or what inferences it might make. We must assume that some AI inferences were made deliberately to damage or hurt national security systems. So the models that we start with tend to be very, very primitive, crude, and not well trained, so we have to train them much longer and not always with the availability of cloud that has inexhaustible capacity. A partner who understands this and provides consistency at all scales is very important.

Offers good performance and
Once, I've been in a program, but they stopped supporting protocols like HTTP, STP, and that kind of stuff. All of the DIP supports at the beginning were kind of support when it was just Python and just five storage. And it happened a few times that the customer required the STP and HTTP protocol for storage. And I was surprised I couldn't do it anymore with NetApp. So, it would be beneficial for them to support both kinds of protocols. The only little black points that I would put on top of NetApp FAS Series. There is room for improvement in deployment and configuration processes. The thing with ONTAP is that we have a lot of layers, from the raw disks to the volumes we present to servers and configure. There are quite a lot of things to configure. Probably NetApp should ease the way to install that. In NetApp products, such as ONTAP and FAS, a solid understanding of storage is still necessary to handle configurations in larger systems. It's not the same with Pure Storage or Huawei. Even someone less familiar with storage could manage it, making it more accessible.

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…
