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.
Dell Unity XT requires improvements in deduplication, user interface, migration, automation, scalability, and support for better efficiency.
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.
In the future, if Dell storages include this option, especially for Unity, it would help us target SME or medium enterprises for quicker closures and support the sales team.
I believe if Dell can integrate AI to predict potential failures, especially in hardware like hard disks, that would be very useful for proper maintenance.
The pricing is a bit higher than expected.
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.
Dell Unity XT provides cost-effective pricing and all-inclusive licensing, balancing cost and features effectively against competitors.
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.
It is priced at around or under $50,000.
The cost is not cheap nor expensive.
Commercially, Dell Unity XT is viable and competitively priced.
The pricing of NetApp FAS Series is not cheap, but in comparison to other vendors, NetApp FAS Series is affordable.

Its data compression feature is the best that we have ever seen.
It helps with data cost management and is seen as a mid-range product with good performance.
We installed the Flash, which makes our IO operations fast and efficient.
If their growth is not significant, we might suggest mid-level Unity storage like Unity 300.
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.
Syed Habib - PeerSpot reviewer
Efficient data replication and fast IOPS have improved operational performance
Dell and a partner jointly implemented this solution in Auvink. We installed the Flash, which makes our IO operations fast and efficient. Replication is available, allowing us to replicate data simultaneously from one site to another. All-flash technology and vTXT enhance speed, and the IOPS are faster. The cache's IOPS are much better. Snapshots provide a unique feature for testing and make management more comfortable and easy. The platform is multi-supported and certification is more convenient and easy to manage.
Arnaud Salmon - PeerSpot reviewer
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.
