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.
I have not encountered any significant issues, such as applying firmware that introduces bugs.
Stability has never been an issue except for minor controller glitches causing failover events, similar to brakes and tires on a car.
I encountered instances where the entire cluster went down due to workload and throughput 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.
Pure Storage FlashArray needs improvements in scalability, cloud integration, user controls, pricing, and compatibility with VMware and third-party environments.
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.
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.
Integrating object storage into the FlashArray would benefit entry-level and SMB customers by offering a more unified solution.
Storing cold data on expensive arrays doesn't make financial sense, and tiering to any of the big three cloud providers would be advantageous.
Currently, the limited selection of on-premise instruments hinders Pure Storage FlashArray's ability to compete effectively with other vendors.
 

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.
Pure Storage FlashArray is costly but valued for performance, all-inclusive features, and efficiency-enhancing Evergreen upgrades.
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.
I prefer solutions with lower pricing.
They're expensive.
The cost of Pure FlashArray is a bit high compared to peers, but its sustainability and features justify the price.
We lost a lot of customers because we couldn't compete on price with other vendors.

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.
FlashArray's integration with the Pure One instrument provides a centralized platform for efficient management of all arrays.
Another noteworthy aspect is their platform, Pure One, a cloud-based analytics platform that automatically creates a case and sends out a part if a disk or controller fails.
It handles internal data migration seamlessly in the background without going offline, achieving a hundred percent uptime.

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.
Barry Sunanan - PeerSpot reviewer
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.

Supercharges enterprise storage by way of highly optimized hardware, comprehensive data management and a feature rich interface.
During their early years, I was a member of Pure's Customer Advisory Board. In addition, when we first adopted Pure, they did not have replication GA yet. We got into their beta testing program and help them work out certain issues with that technology. One weakness I can say the array has, still to this day, is limited control on scheduling snapshots. Depending on the type of replication schedule you are building, you may or may not have control on specifying the start time of a given replication schedule. This is not a very big problem in the grand scheme of things, but something nonetheless that has bothered me about the scheduler in general. Another area for improvement would be automatic host alias creation. Other platforms such as EMC Unity/PowerStore will automatically detect the host name, create a alias for it and associate the logged in HBA's to it. Pure does not do this for you and as a result, requires manual configuration. This can be very time consuming especially when you are deploying a large number of new servers.
