Sentiment score
7.8
NetApp AFF offers scalable, adaptable storage solutions, easily expanding without disruption, though cost and physical limits present challenges.
It is highly scalable.
It is suitable for both medium-sized and enterprise businesses.
It hasn't broken down anytime in the last six to seven years, despite hurricanes, earthquakes, and power outages.
I rated the scalability as seven because even though the solution can scale, load balancing must be done manually, as it's not automated.
You can add more disks, more disk shelves, or migrate the data seamlessly.

Sentiment score
8.2
Nasuni is praised for its stability, offering reliable performance, minimal maintenance, and flexibility with virtually no downtime issues.
Sentiment score
8.4
NetApp AFF is highly stable, reliable, and handles tasks without disruption, with minor bugs resolved quickly.
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.
 

Room For Improvement

Pure FlashArray X requires cost-effective improvements in UI, integration, cloud features, multitenancy, analytics, backup, AI, and scalability.
Nasuni struggles with cloud integration, performance, and user experience, needing improvements in data retention, security, and analytics.
NetApp AFF users seek easier setup, enhanced management, lower latency, better support, improved documentation, and cost-effective, scalable solutions.
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.
We mostly rely on long-term releases. We don't need the most up-to-date features, but we need a reliable environment.
I suggest Nasuni improve their syslog forwarders to support TCP protocol, as it's more secure than UDP, which is plain text and not protected at all.
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.
 

Setup Cost

Enterprise buyers see Pure FlashArray X NVMe as a justified premium investment due to performance and comprehensive licensing.
Nasuni offers competitive pricing with flexible cloud compatibility, licensing per terabyte, and cost-effective enterprise solutions.
NetApp AFF pricing varies widely, viewed as expensive yet cost-effective, with negotiation impacting affordability and overall value justifying 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.
I would give it a nine out of ten in terms of costliness.
I prefer solutions with lower pricing.
NetApp support is cheaper than Dell support.
While it is not cheap, they have introduced a new series of AFF that are more affordable.
 

Valuable Features

Pure FlashArray X NVMe offers exceptional performance, reliability, scalability, and seamless VMware integration, enhancing workload efficiency and user experience.
Nasuni provides scalable cloud-based file management with global file locking, data security, and efficient disaster recovery features.
NetApp AFF excels with efficiency, seamless ONTAP integration, ease of use, high availability, low latency, and real-time replication.
Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator.
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.
The features I find most valuable in Nasuni are the unlimited snapshots, antivirus capabilities, auditing, and ransomware protection.
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.

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.

It helped us save 40 to 45 percent on some types of data
It can provide a 360-degree view of your data, depending on how you implement it and whether you're storing your data in Nasuni. However, if you're working with multiple cloud providers, I don't think it's mature enough to provide a 360-degree view of what's in AWS, Azure, and Google Cloud. I think it can do it, but it's still a lot of scope and range fitting. Given that Nasuni storage is actually cheaper in some areas, it made sense for us to move a lot of our data away from Microsoft. Nasuni gave us more of a 360 view of that particular data type. Other data types are a little different because the company went in a direction where they wanted to store some stuff in an AWS S3 bucket rather than a file storage system. An S3 bucket has its advantages, but if you were to store more of your data in Nasuni, you would get a wider 360-degree view of it rather than on several cloud providers. I have data in AWS, Google, and Azure, and I would like to see a wider view of all the data stored across these three top providers. Currently, I use it for AWS and Azure, but I couldn't use both of them at the same time. I think Nasuni could have better visibility across these different areas. I had to take my data out and then do some analysis to get the costs. It would be helpful to have more built-in analytics tools to compare the storage costs between the various cloud providers. I would also like some graphing capabilities. We had a tool called Grafana that we used for graphing. I think some more visual analytics like that would be nice.

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.

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…
