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.
Pure has good storage.
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.
I have communicated with them, and they are effective and responsive.
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.
 

Scalability Issues

Sentiment score
7.1
Pure FlashArray X NVMe offers scalable storage with low latency, easy upgrades, though capacity customization and high costs are noted.
Sentiment score
7.8
NetApp AFF offers scalable, flexible storage solutions, allowing easy horizontal and vertical expansion despite some cost and controller limitations.
Sentiment score
7.4
NetApp FAS Series offers impressive scalability and efficient data handling, with considerations for cost and planning for expansion.
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.
You can add more disks, more disk shelves, or migrate the data seamlessly.
I would assess the scalability of NetApp AFF as excellent in handling massive data volumes.
We normally avoid current versions and use versions that have been running for at least two months in client usage before updating drivers.
NetApp FAS Series is scalable, and it is possible, but you need to pay.
The NetApp FAS Series is scalable and offers numerous solutions, but only if customers are willing to invest in the shelves.
 

Stability Issues

Sentiment score
8.1
Pure Storage offers exceptional stability and reliability with outstanding support, consistently achieving high user ratings for performance and service.
Sentiment score
8.4
NetApp AFF is highly praised for its stability, reliability, and efficient non-disruptive operations, making it ideal for critical environments.
Sentiment score
8.0
NetApp FAS Series is highly reliable with minimal downtime, praised for redundancy and continuous operation despite occasional issues.
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.
Most things are tailor-made, and we avoid downtimes even with primitive CLI commands.
 

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 improved setup, intuitive interfaces, robust third-party integration, and enhanced management and support features.
NetApp FAS Series needs better performance, integration, monitoring, pricing, usability, and support to enhance competitiveness and user experience.
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.
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.
Storage companies should create encrypted storage solutions between the OS and storage to protect against ransomware attacks.
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.
 

Setup Cost

Enterprise buyers see Pure FlashArray X NVMe as a justified premium investment due to performance and comprehensive licensing.
NetApp AFF offers competitive pricing, valued features, and flexibility, though some users find expansion costs concerning over time.
NetApp FAS Series is seen as high-cost but justified by features and performance, with negotiable pricing and discounts.
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.
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 licensing cost of the product is expensive, and when combined with support, it becomes quite costly.
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 offers high speed, low latency, and robust performance with advanced data management and seamless integration for storage solutions.
NetApp FAS Series provides reliable, flexible storage management with high availability, supporting SAN/NAS protocols and VMware integration for cost-effectiveness.
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.
You can even download the ONTAP simulator and deploy it on your virtualization platform and test almost all features.
Data reduction capabilities such as deduplication, compression, and compaction are standard features included with the license in NetApp AFF.
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.
Our IOPS are very high, reaching somewhere about 50k to 150k or 1.150k.
One important feature for customers is its ease of use and continuity, enabling seamless usage across on-premise and cloud environments.

Jaehoon Oh - PeerSpot reviewer
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.

Offers seamless installation and efficient data handling with robust support
NetApp AFF provides an all-flash storage solution for unified SAN solutions, supporting both SAN and NAS functionalities. 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.
Srikanth Purushothaman - PeerSpot reviewer
Has supported long-term data protection and backup while requiring better part availability and pricing options
For monitoring purposes, we normally use flash access storage exclusively. We utilize a hybrid system because we need performance, combining NL-SAS for the volume and SAS flash to use as a fast cache system that provides more IOPS. We normally implement RAID 10, which we prefer over RAID 6's n plus 2 combinations. We utilize it for data redundancy, even with write intensity on. Regarding the unified storage architecture for NetApp FAS Series, we normally opt for exclusivity unless budget constraints exist. Our IOPS are very high, reaching somewhere about 50k to 150k or 1.150k. The high performance ensures minimal latency. An advantage we've seen with NetApp FAS Series is that snapshots provide very rapid backup and fast recovery. We basically use snapshots for data protection as first-level protection, with deduplication between the two storages serving as second-level protection.

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…
