With Pure FlashArray X NVMe, we need to escalate the issue and get an account manager for its resolution.
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.
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.

You cannot increase capacity if latency is present.
It is highly scalable.
It is suitable for both medium-sized and enterprise businesses.
Lenovo ThinkSystem DM Series is scalable, and I would rate its scalability as a seven out of ten.
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
8.0
The NetApp FAS Series is praised for stability and reliability, with users noting minimal issues and high performance.
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.
If I have sold fifty boxes, about fifty percent of them experienced failure.
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.
Lenovo ThinkSystem DM Series needs licensing flexibility, enhanced features, better service, and improved pricing and management.
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.
Many customers have lost data while configuring it, indicating a need for improvement.
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.
Lenovo ThinkSystem DM Series offers competitive pricing comparable to Dell and HPE but with complex cost calculations and optional features.
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.
There are extra expenses beyond the standard licensing fee for features such as replication and deduplication, which are available on demand.
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.
Lenovo ThinkSystem DM Series is praised for FlexClone, cloud tiering, data efficiency, and ONTAP features, offering superior service.
NetApp FAS Series excels in high availability, integration, and efficient storage solutions, featuring robust disaster recovery and unified storage.
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.
One of the most valuable features of Lenovo ThinkSystem DM Series is the snapshot feature.
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.

Reliable and fast servers with good support
We use on-premise servers with Lenovo ThinkSystem. We set up Hyper-V and load multiple types of servers including a domain controller, a SQL Server, and application servers The solution provides fast servers that are reasonably priced. We set up RAID ten to ensure drive redundancy, leading to…
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.
